Sorry guys I've been away for some years.Did this ever get resolved?
Yeah, it's A. GLaDOS even says "speedy thing goes in, speedy thing comes out". The box has no momentum and that is retained.
fpbp. Bfags BTFO. /thread
>>724289883ThisThe cube's momentum starts the attosecond it's atoms go through the portal, so AT BEST it will do a little hop when it comes out. But the speed or momentum from the piston is irrelevant.
>>724289883If I handed you a calculator and had you type in 2 + 2 and it gives you a 5, would you trust that calculator to do math? No, you would not. So why are you trusting the words of a murderous malfunctioning sentient robot?
>>724289803B fags be like>put hula hoop over penis really fast>penis flies out at the speed of light
Test.
>>724289803Yeah. It is both depending on which school of thought you want to follow because portals do not exist. If you want to follow a static state of physics it is A.If the box was steady on a table on the surface of the earth and the portal was placed on the floor right next to it then its relative position and speed do not vary and it is A.BUT as I said the answer is relative.If the same box was placed on a platform going 600 km/h orbitting earth on an opposite rotation than that of the earth and the exit portal was placed on a floor on earth then you suddenly have a box whose relative position and speed changed dramatically from one spatial position to the next and you get B and a box that basically became a bullet.tl;dr it greatly depends
>>724290008Because that murderous robot gets math right?You fucking imbecile
>>724290185Maybe if you're a retard.
Ending proves B
>>724290256Try better bait.
>>724290280Explanation.
>>724290319This. The answer greatly depends on the initial states of both portals.It can be either.
>>724290280How does this prove B?
>>724290280Retard you better not be saying that UHHH MOON FAST = AIR SUCKED
>>724290319the 2200mph vector of the person is not relative to the blue portal. their velocity relative to the portal is zero.
>>724290391The moon is moving at extremely high speeds, so if Chell were to remain at her relative speed to the Earth (A), then she would be either crushed against the moon's surface, or left behind in space by the moon.If it's B, her speed massively increases to match that of the Moon. The video obviously proves B.
>>724290451The speeds are relative to the surface of the Earth obviously, since the moon is moving in the scene and the Earth isn't.
>>724289803It’s always been A. Bfags are coping midwits.
>>724290280That’s the vacuum of space
>>724289883The portal does.This momentum is transferred to the cube exiting it.
>>724290623Yes anon, very good. And can you point to the big white thing? Yes, it's the moon! I'm so proud of you!
>>724289803real answer: it's neither
>>724290493Ah, shit. You're right. It would be like placing a portal on the side of a truck speeding down the highway and then stepping out and expect to still be going the same speed and direction as the truck.
>>724290678As a 4D doorway the portal resolves the reference point difference. It’s just a doorway.
>>724290656not momentum, just velocity
>haha look guys I'm pretending to be a genuine retard A-fag>so epic I'm le trolling everyone :)))) I love 4chan humor
>>724290809You accidentally typed A instead of B.
>>724290861um no i did notretard
Low IQ is AMid IQ is BHigh IQ is A
>>724289803>frame of reference>momentum can have a negative valute>all momentum deficit must be resolvedit's b.also, if you replace the cube with a person, this would be lethal if the orange portal was moving at a really high speed.
The distance between the orange entrance and the blue exit is always 0. It’s a 4D spacefold that functions as a hula hoop.
Here we go.
>>724292078lmao retard
>>724289803Post IQ and your answer. I'll start>A
>>724290280Ending proves that's not the real moon, actually. There's simply no way it's far enough.
>>724290805What COMES with velocity and mass?
>>724290008>Bfag schizzo babblesEvery single time
>>724290280That's the vacuum of space, you fucking retard. These are troll posts, right? I'd much rather admit to being baited than believe someone can be this fucking stupid.
>>724289803No. Since portals don't exist we can't observe their true natures so everything in this thread is conjecture.
>>724295736>everything in this thread is conjecture.It would be, if the game didn't explicitly tell you how they worked. >Spectacular. You appear to understand how a portal affects forward momentum, or to be more precise, how it does not.
>>724295565that's not making the point you think it's making. you misunderstood because you're stupid. it has nothing to do with the suction and nobody said it did. that's something you made up and got angry about apropos of nothing. I can only imagine what a tiresomely angry little faggot you are IRL.

>>724293683>76 IQ>A
>>724289803Yes, behold the B fag.
>>724296243portals can't move ingame so this point is moot.when you tweak the game to allow them to move, the ingame results are A
>>724295565She goes the reverse through the portal though, against the wind.
>>724300028Wrong, there's a cutscene where a portal is placed on the moon which moves at 2200 MPH. Cutscenes always override gameplay in terms of lore: It doesn't matter if you can beat a boss in one shot in game, if the cutscene shows them defeating you then they defeated you in lore.
>>724289883>The box has no momentum
>>724300780your little sister
>>724300028>portals can't move ingameWrong, see the Neurotoxin Chamber and the Moon>when you tweak the game to allow them to move, the ingame results are AWrong, the in-game result is C because the engine can't pass a stationary object through a portal.
>>724289803It's between the twoSome of the force gets absorbed by the material beneath but some of it gets reflected back up onto the cube
>>724292078>"force of energy"Afags don't even understand high-school level Newtonian mechanics. This is why you'll so often see them saying nonsense like>it's changing position but not moving>it has a velocity but no momentum>it's only a perceived velocity, not a real velocity
>>724301378lmao just realised there's one such example in this very thread that I hadn't seen>>724290805
>>724293683100 IQB
What if you put one portal on earth and you shot the other end up in the sky and it would activate once it reached Venus which has like 100x more surface pressure?
>>724289803
>>724302051I guess you'd have a stream of pressurised Venusian atmosphere blasting out of the portal.
>>724289803If the portal hits the cube at 100mph, then the cube will come out of the other portal at 100mph for the entire length of the cube. Right? It seems intuitive
>>724302505Don't ask Afags how the cube is supposed to emerge from the portal.
>>724290185If you want to follow the "my physics are inconsistent and I do not understand them", sure, go for A
>>724290008because i want to have sex with her
>>724292078>What force of energy is moving the boxIts own inertia. It's keeping still in its own pov but the universe suddenly and dramatically shifts speed.Yes, I am implying that when a portal moves somehow the entire universe is effectively being push and pulled around, so in a way I'm making an even more ridiculously sounding point that instead of a mysterious force pushing the cube there's a vastly more mysterious force moving a fucking universeBut it's for the purpose of continuity, which leads into>Create entirely different scenarioWhen B fags show you pictures of slightly different scenarios its to illustrate how ONE set of rules works consistently between examples. Do you break down crying when you play an fps game and you enter a new room and an npc is standing in front of you shooting you, because you don't know if pressing certain buttons will make you shoot anymore?No retard, the rules stay the same.>Post a gif of b happeningYeah it's retarded to paint a picture and just proclaim "see! this is proof!" but this is ALL a fags actually do as well.>Ignore relativity on the platform sideThe cube is moving into a new inertial frame, and nothing is changing about it from the old perspective. If you were tethered behind the cube following it into a new portal, it would simply remain the same distance from you as the portal envelopes it and then envelopes you.>not portals from videogameWe are strictly talking about how the in portal universe describes itself through various examples>wind resist, elevation, etcNo we're not, the most clean examples use frictionless space for demonstrations. But again, you'd just say "OMG THATS AN ENTIRELY DIFFERENT SCENARIO!" so it's pointless
>>724290008GladOS didn't invent conservation of momentum.
>>724303127NTA but the thing is that both sides believe in conservation of momentum. Bfags just think it's relative to the portal while Afags think it's relative to some universal reference frame (like a game-engine coordinate system).
Why wouldn't this work?
>>724289803Yes, it's B. Every thread is filled with irrefutable arguments for B and the other side is left impotently seething. Some people still don't get it but that's all right. Some people don't get that the Earth is round, either.
>>724290075Objectively it flies out as fast as you put the hula hoop over it. And then stops when you stop the hula hoop. Note, the blue portal does not change its motion in the same way.
Afags will never understand that you can just keep zooming out.
>>724291013Right so <80 = A, 80 - highest ever measured = B, hypothetical higher IQ = hypothetically A again for reasons unfathomable for anyone currently or historically alive? Because I've never seen one intelligent, consistent, logical argument for A.
>>724291029You know what they say, it's not the fall that kills you, it's the sudden stop at the end.
>>724291198And that results in B, naturally. A cube going through a stationary hula hoop.
>>724303021
>>724304287Explain your working
>>724293683135B
>>724304287this makes significantly less sense
>>724303987The energy required to sustain the portals is greater than what you get out of it, or something like that.
>>724289803Is there a definite answer? Yes, it's B. Does everyone accept it? No.
>>724303987Water would slow down gradually until it stopped falling
>>724304590why?????
>>724304287>>724304303>>724304324That's almost the right idea but it got it reversed. Only the last one would slide
>>724304765It'sa me, Isaaco Newtono!
>>724304765That might be it if all but the last one was already on the ice. As it is, they all go through, they're all in motion.
>>724304287saddam hiding spot
>>724304287I think the idea here is that the each cube would be pushed by the cube behind it except for the last. But if you extend that idea to the particles within the cube you can see that the front of that cube would be pushed by its rear, and so on such that in fact all 5 cubes would slide.
>>724304179Here's the original webm
>>724305438kek
>>724292078So this is what it's like to go through life perpetually confused, huh
>>724290075Afags be like>Dude if I move my ass over your dick then your dick isn't moving which means it isn't sex and we're not gay
>>724305438Error detected, I zoomed out again, now the portal was stationary and everything was being pushed up. You now are saying speedy things going into a portal do not come out speedy. Logic error. Logic error. Logic error!!
>>724304303>>724304324>>724304765the last block in line is the only one with nothing pushing it
>>724306610the back of the block pushes the front of the block
>>724306610>>724306642In fact nothing is pushing anything because nothing is standing still to begin with.
>>724307563Now show scenario A where the shaded copy is showing the room falling on the cube that's just sitting on the floor and not going anywhere.
Afags are unironically midwits
Are Bfags afraid of hula-hoops?
>>724308274Things leave hula-hoops at the same rate they enter hula-hoops the same as portals in B.
Never forget that some B rainless idiot posted this and unironically thought it proved B
>>724290391Because B tards are too stupid to understand space is a vacuum so everything in that room is being sucked out
>>724308094Scenario B Averi's portals.
>>724308467Averi has no portals but if she had them, they would confirm B
>>724308093
>>724308462>space is a vacuum cleaner that can suck fill grown people into itStop watching too many bad scifi films with that tired trope
>>724308093That would be a denial of the motion of the blue portal and a misapprehension of the forces at play
>>724308403>Wow can you believe he just posted this clear proof of his position?
>>724309406That's literally the exact opposite of B you moron
>>724308462That's not even remotely what the image is about.
>>724290075
>>724289803Question for the Afriends: what is B even doing here? Why is this even a question? What do you think the person who came up with this was thinking?I feel like a lot of you genuinely don't even understand this, which means the entire reason for this discussion has gone entirely over your heads in the first place.
>>724309460Oh dear >>724304179
>>724309578Well, you're half right From the right side they both look the same, so the same thing would have to happen in both cases. And you understand it can't be that the cube doesn't move. In fact, it does already move in both cases even in your animation, you just try to skip over it by making it happen very quickly.
>>724309623Consider the difference between this and the OP.You have the blue portal move, and then stop. In the OP, it also "moves", but then it doesn't stop. If you want the exact same outcome as with a hula hoop, you have to give the blue portal an acceleration that corresponds exactly to the one undergone by the orange one.
>>724308462Newsflash tardo, that's not what the pic/webm is implying
>>724308462>>724309821The thing is, if this discussion were happening in a vacuum (lol) then I could understand the misunderstanding. But it comes up in every thread and we still have to do this song and dance of A misunderstanding the argument and having it be explained to them and then by the next time they've forgotten. It somewhat strains my belief in the good faith of the A side. Are we all just pretending this is the first time we're seeing this, for the sake of the game? Because I'm on new game + here. I can actually remember previous conversations. Maybe Afriends consider that a mighty intellectual fest, as well.
>>724310003I wasn't supposed to break kayfabe huh
>>724292078>what force is moving itIf you recall 4th grade physics, you don't need a force to move something, only to accelerate it. An object in motion will stay i motion unless acted upon by an external force.>different scenario constructed solely to make B workNope. It's a different scenario to prove that B is consistent with itself.>Post a gifWe only use gifs to illustrate our arguments and logic. Afags post gifs of B and go>hurr durr look how silly B looksWith no argument.>Ignore relativityNope. That's you, acting like there's some absolute universal coordinate system.>Start pretending these aren't the portals from portalWhat? B is perfectly consistent with every behavior seen in the games from a regular portal fling to the moon scene and everything in between. A breaks as soon as you walk through portals pointing in different directions.>Add shitWhat? B works perfectly with only the variables given in the original.>Call you retarded without explaining whyBecause you're too retarded to understand why.
>>724293683Oh shit my bad. I meant to type B. I only noticed now because I was having sex with the mothers of every single Afag.
>>724309547>What do you think the person who came up with this was thinking?Oh that is simple, he though: trololololo
>>724311992You only think that because you can't make any sense of it. And yet the question remains the same: why B? Why not any other old nonsense? Ever notice all the B arguments are consistent? That would be hard to do with random nonsense. In fact, we'd expect something closer to what we see from A: everyone coming up with their own ad-hoc rationalisations, starting from the conclusion, and just insisting they're right in the face of evidence to the contrary. Fact is, something is happening here that is simply beyond you, and you don't even know where to begin.
>>724290319except the earth is also moving
>>724311992>>724312442You know, with those old troll physics memes you could always tell what the trick was. Mount a magnet on the front of your car to move it, use a fan to propel your sailboat, jump just before the elevator hits the ground, etc. There's an underlying logic that allows people to argue for it, and you have to find the flaw in it. So even if you think it's just trolling, what's the logic?
>>724312589Yes. But that also doesn't matter because motion is relative and B is the right answer.It'd be a massive issue for anyone trying to argue for some sort of objective inherent momentum within a universal reference frame, though!
>>724289803some physicist answered it in relation to wormholes, it's B based on physicsin-game it depends on what the developers decide, there are contradicting answers from the devs I think but if Portal 3 is ever released it's going to be B because A would be a real brainlet tier answer and A tards would cope by saying it's not the same valve anymore or something
>>724289883This should’ve been the first and last reply but the stubborn faggotry of /v/ will never end./thread
>>724313304>So, we had designed a prototype for Portal 3 with moving portals, and we used the simple rule that anything that goes in one end comes out the other at the same speed, relative to the portal>This naturally caused cubes to start flying all over the place! We had some great ideas for puzzles>But some of our playtesters got really confused because they thought the cubes shouldn't be moving >So, in the end, we decided to scrap it
>>724313574That line describes B, though. Speed is relative.
>>724293683Fuck IQPost your answer and immigration policy
>>724313781I mean that could happen, every time I listen to dev commentary in one of valve's games the testers always come off as being ridiculously stupid
>>724309547The plain fact is that Afriends don't understand B and they don't even bother to try. They think they already know everything there is to know, and whatever is unfamiliar or strange must therefore be wrong. Bchads, on the other hand, saw something that may not have made sense to them, and tried to make sense of it. Their attitude is fundamentally one of openness and curiosity. They arrive at B through the rigorous and continued application of logical thought to the problem. Afriends decided their position from the outset and never questioned it. There's no shame in thinking it's A initially. It has its straightforward appeal. But no one who is actually willing to think about it and question their assumptions in good faith clings to it.
>>724289803I don't know what's the answer is, but I know it is neither A nor B.
>>724315338Curious to hear your reasoning
>>724313894A is quintessentially globohomo.
>>724316872MODS!?
>>724316872
>>724315571It seems inherently conservative to me. Don't think about it too hard, just accept what you were told, new information is just a trick to steer you away from the truth. It's not moving, simple as. Common sense, you know?
>>724317138L-lewd
You would only ask this question if you never finished the game.
>>724317138I get that it's more aesthetically pleasing but the cube rewinding back to its starting position does rather confuse the point.
>>724289803It's A
>>724317297No, plenty of Atards seem to have played it. Doesn't mean they understood it, of course.
>>724317397Surely no one is stupid enough to get confused by that right?>all the idiots who think that A is a parabola and B is an infinite straight motion without gravity or air resistance>all those threads with arguments about conservation of energy>tards in this very thread who think the point of the moon argument is about air pressure>if you drop a cube between a pair of portals eventually the gravity of the Earth will run outNever mind.
>>724318019You give 'em anything at all to cling to and they'll do it
>>724318019>if you drop a cube between a pair of portals eventually the gravity of the Earth will run outwas this really a thing that happened here, oh my fuck lmao
>>724313894B.My ideal policy would be that they're not allowed in at all, but my compromise is as follows:1. To be allowed in, they must get at least 130 IQ on an official test. Otherwise it's not even worth the effort.2. They must willingly sterilize themselves as to not pollute our genes.3. Anything more severe than a parking ticket is punished by execution, but I might settle for permanent deportation.4. It's illegal to hire a foreigner as long as there's even one comparable native applicant.
>>724318576Yes, several times in fact. It's an argument against infinite energy machines.The better argument is to propose that portals draw from some unseen energy source and do work when things pass through them. There's no canon support but it's at least grounded in reality.
>>724298272Is this supposed to be some kind of gotcha? That makes perfect sense and is entirely consistent with everything seen in the games.

>>724319000No one actually thinks this is sensible, right? I guess that's the difference. The Buster Keaton one is -literally- just B. They think B itself is punchline enough. The one you posted however shows the implications of A. If the cube's not moving you can keep moving it around without moving it. Even typing it out is impossible without contradiction. Of course, it's easy for them to say "yup, looks fine!" but they can't say what they think is actually happening here

>>724289883>speedy thing goes in, speedy thing comes outIrrelevant, this is a non-speedy thing going in, so what happens then? We don't know, there's no canon to prove it.
>>724319739>I need to be told what to think
>>724319739The point of the saying is that momentum is conserved, and the box has none.
Some players still don't get it
>What's your argument?>I animated it working as I say
>>724319739Well, speed is relative. The cube is moving quite fast relative to the portal. And if we simply must say that it's stationary, there's also an answer: >>724301015Basically, it's never gonna be A because A tries to have its cake and eat it too. If it's not moving, it's not coming out of the portal. If we consider that motion is relative, the cube flies off. But you can't have the cube come out and then stop.
>>724319680You're brown.
>>724319871Momentum is an emergent property, not an inherent one. Everything has momentum in some frame of reference. Portals just take something and put it in a different frame of reference with different momentum in one continuous motion. B is in fact already what you see in the games.
>>724320070I'm translucent lily white and you're a simpleton relying on heuristics and bias.
did you know that momentum doesn't actually work in the game? like you fling from a portal not because you kept your speed but because the surface of the wall is scripted to fling you in a certain direction if you meet certain criteria. you can be flung even without a portal if you position yourself just right.https://youtu.be/d4A0l39GBTo?t=214
>>724319557It is sensible if you believe A is the answer and you just look at the animation in a vacuum and don't think too much harder about any other interactions that might happen. The real gatcha is when someone who says the answer is A thinks this is a different situation and that something else should happen since it shows they are inconsistent in their reasoning. The logic of A seems to not be based on any rules, but simply that whatever looks right should happen and you can find an explanation later.

>>724320612Open door 2 and half flip the lever.
>>724320720It does because the stationary object has no momentum, so it is conserved upon exiting the portal.

This did get resolved.In the actual game engine, A happensPhysicists state that B would happen, but since the premise is impossible, it's purely theoretical
>>724321927>you're not jettisoned out through itYou are - relative to the doorway.Now, consider, there's nothing else you *can* do than go through.Now further consider that the blue portal is stationary. This last one is the relevant difference between your regular doorway and the OP. You can't simulate this bit with a door. But, again, the door you're exiting is stationary, and you're moving in relation to it.
>>724289803Technically A but portals can't move once opened. .
>>724312589Exactly. So that just proves it's B even more.
>>724321985Translating relative momentum is *literally* all portals do. They made two games out of this concept.
>>724322531You don't magically gain momentum from passing through it. The door or in this case the portal does not magically transfer its momentum to you or the cube.
>>724322290I've yet to see an Afag with a basic understanding of reference frames.
>>724322290This is cope. I've never seen anyone on your side come close to giving an intelligent response. But I'm to believe that, hypothetically, someone with a double PhD in relevant fields would disagree with me because the low-IQ ape told me so?
>>724322485Neither A nor B happens in-engine because the devs didn't allow for moving portals to engulf stationary objects.B does happen in-canon though, the moon scene shows us an excellent example of conservation of portal-relative momentum.
>>724322485>In the actual game engine, A happensIn the actual game engine, this happens: >>724301015
>>724322649The answer you give depends entirely on which reference frame you favor, if you think the cube matters more you support A, if you think the wider system matters more you support B. Retards stop here and support B, but the answer is neither because this is a nonsense question. There is no more or less correct.
>>724322645>You don't magically gain momentum from passing through it.No, everything just continues unless a force acts upon it. A force stops the orange portal, but not the blue one, nor the cube. This in contrast with a hula hoop, where stopping one side necessarily stops the other.
>>724321926>misrepresents A to chatgpt>calls everyone else retarded
>>724293683127 but I was on an off day when I took my IQ exam so it could easily be above 130.It's A.
>>724307563This gif was already disproven and giving it a new coat of paint doesn't change the fact that any cubes at the side would be unaffected.
>>724322919Actually retards then declare "hurr durr it's not real, both sides da same" even though you had no problem with this "nonsense" whilst playing the game but you are now suddenly unable to entertain a hypothetical because you can't distinguish between a logically valid argument and a contradictory one. Assuming portals, it's B.
>>724323096>This gif was already disprovenCare to tell us how?>any cubes at the side would be unaffected.What does that even mean lmao
>>724322773>the moon scene shows us an excellent example of conservation of portal-relative momentum.Webm or it didn't happen
>>724322608And the cube has no momentum so no momentum is transferred, resulting in A.
>>724307563The gray plane is traveling the opposite direction, thoughbeit
>>724323258https://www.youtube.com/watch?v=DAn87KyNjJ0>the moon is going sideways very fast (orbiting)>on passing through the portal, Chell gains this sideways velocity>Chell's velocity relative to the portal is conservedQ.E.D: B
>>724323683That's the vacuum of space sucking the air out of the planet.
>>724323294Momentum is relative. Yes, the cube has momentum.

>>724323834The portal has no momentum because it has no mass, so the cube has no momentum relative to it.

>>724324262Watch the intro for rachet and clank a rift through time retard
well either way, black people invented portals
>>724324151That's not how that works. The cube has momentum when measured relative to a frame of reference. Even if you don't include anything else in that.
>>724323945NTA, but what exactly is your point? Because if you're trying to claim Chell is sucked out onto the Moon because the Moon is moving really fast, you're blatantly, demonstrably wrong, and you need to stop talking.
>>724324163Lol brownie
>>724324371This.
I'm a research physicist at a U.S. DOE national labit's A
>>724324402But it has zero momentum in absolute terms and you cannot magic momentum out of nowhere by changing your spatial frame of reference
>>724324370You watch the intro to Dawn of War. It was pretty badass. And it's about as relevant.
>>724324448No, no one is claiming that. The point being made here is that the portals in this scene are in motion relative to each other but you can pass through them as if they aren't. That shows that relative motion (otherwise known as "motion" to people who know what they're talking about) is what matters here.But you've already had that explained to you a couple dozen times if you're at all familiar with these threads so again, why the dumb question with an assumed strawman?

Are there any genuine Afags left at this point or just Bfags pretending for easy (you)s? We've been arguing for like a decade.

>>724324893Dumb and retarded. Divine intuition tells me he couldn't be any more wrong.
>>724325373Yeah. If you take the question at face value it really is just asking what happens when a door frame falls around someone.B only becomes an option once you get into the weeds of the question, but if you're getting into the weeds the next actual logical step isn't to say it's B it's to just admit how stupid and impossible the question is to begin with.So yes, I think the answer is either A, if you just take question as presented, or the answer is fuck off and come up with a better question and properly define the portal behavior if you want to get into the weeds of it.
>>724321926>So with a fall from height, you get B: the cube is launchedThat's not even the question. It's not about a cube falling, it's about a piston pushing down.
>>724326190>webmlmfao
>>724326168>but if you're getting into the weeds the next actual logical step isn't to say it's B it's to just admit how stupid and impossible the question is to begin with.Cop-out. No, you're just not able to think it through, nor even realise how contradictory A actually is. We're both taking the question as presented but I'm just more intelligent than you.
>>724309578physically those are the exact same collision
>>724326168>B only becomes an option once you get into the weeds of the question, but if you're getting into the weeds the next actual logical step isn't to say it's B it's to just admit how stupid and impossible the question is to begin with."The question only becomes stupid and impossible once my answer isn't the right one"Afags really are stubbornness incarnate. And no it wasn't A even at face value. Because the problem specifically isn't the equivalent of a door frame. Since that would be when the portals are not back to back.
Why are Bfags so fucking stupid? Holy fuck.
>>724326168>properly define the portal behaviorWhat goes in one comes out the other. We should be able to agree on that one. B follows from there, if you actually think it through. That's literally enough already.

>>724290493Relatively speaking the earth is moving at a much higher speed compared to the moon so this example doesn't really do anything to prove B.

>>724289803There is no universe where A works. B works in some interpretations and an hypothetical C where the cube doesn't pass though the portal at all works in the other interpretations.
>>724327576And actually I probably should add, it's physics fanficton without any actually agreed upon information. It's literally just headcanon all the way down.
>>724324893Only whites can comprehend this logic. Browns will continue to spout A bullshit as their final cope for they are incapable of comprehending white science.
>>724289803B is the most intuitive answer>the rate that a portal envelops an object is the rate an object emerges on the other side>there's no reason for it to suddenly stop emerging, so it continues along it's path
>>724327368Seems like you've surpassed the vast majority of Afags by actually understanding that the Moon scene is B instead of getting confused and thinking we're talking about the air pressure. How do you explain why you were able to figure that out and not your fellow Afags?
>>724327875Why does 2.3 assume the stationary cube isn't stationary
>>724327553
>>724327553No it isn't. The Earth's surface moves much slower than the Moon's orbit.
>>724300825Holy fuck lmao. Perfect

>>724289803I'm a hapa of the two smartest races on earth and it's B.
>>724289803I'm white and it's A.
>>724327553Relative to what? The sun? The center of our galaxy? The center of the universe?In any case it varies depending on which point of orbit the Moon is at.
>>724327608If you blast a hole around me standing still, the hole won't suddenly drag me along with it.If you blast me into a stationary hole, the hole won't suddenly be dragged along with me.
I'm blackmy people INVENTED portalsregardless of the answerwhich we will also invent
>>724327553>Relatively speaking the earth is moving at a much higher speed compared to the moonRelative to what?The point is that the moon is moving relative to the earth's surface. Otherwise it would never been seen at different places in the sky when standing at the same place on earth. And you can literally look up the orbiting speed of the moon to see it's movement is actually insanely fast relative to the earth's surface.Chell's motion relative to the exit portal ended up being the same as relative to the entrance portal on passing through. Despite that demonstrably being a massive change in motion. Which is incredibly accurate to B's logic. Anyone who doesn't see that the moon scene is B does not understand B.
>>724328634Don't tempt with KSP again
>>724324893Bfags actually got one up on Atroons. Atroons, your response?
>>724328028It doesn't "assume" anything. 2.X are all showing various permutations of moving portals and cubes. Only 2.2 is the standard "portal paradox" question.
>>724324893>furtranny
>>724328028>Why does 2.3 assume the stationary cube isn't stationaryI don't know what you're trying to ask. 2.3 doesn't start with a stationary cube, it's like 2.1 where it starts with a moving cube.If you mean "why does it BECOME stationary", then that's because it emerges from the other side at the exact speed the portal is moving, so it effectively goes nowhere. Making those not the exact same speed would make it not stationary.
>>724328020I recognized it here >>724290741A is still correct, but the devs changed the laws of physics to make Moon Scene work for a dramatic ending.
>>724327094The entire gameplay does, really. Think about it. What do portals do? They make a cube's momentum change instantaneously, without affecting it directly, simply by changing the context of its momentum. Everything you do in the games is B.
>>724327576>everything here is literaly physics fanfiction.A is. B is applied logic.
>>724330943You misunderstand. You *should* be inheriting the truck's momentum. That's only logical. And the Moon scene works the same.
>>724289803It has been answered, yes it's in GMod, yes it uses the same engine/physics as Portal, jes this is factual and how it would actually be/act.Idk why people still argue about this.
>>724324893>people have modified the game engine to allow for movable portals, and in the game, A happens. HOWEVER blah blah blahWhat is this mental Billness
>>724289803Indeterminate
>>724331779You wouldn't get it Atroon
>>724331779Yeah, it's completely wrong. A doesn't happen in the game either.
>>724297346I still wonder how A-tards deal with the individual molecules that comprise the cube having no momentum when coming out but miraculously not compressing or deforming the cube immediately from the things behind it
>>724289803The speed of light is too big to make B possible outside of celestial scale spacetime distortion
>>724332210Could you explain what this has to do with anything?
>>724332176You should really just ignore most of what they say. Momentum is not important for A and it is all about the fake movement that is tied to the movement of the portals. Just take their hula hoop argument and swap if for a box with a hole where the box moves over the cube. The "velocity" of the cube is just the velocity of the cube plus the velocity of the portal it is coming out of plus the velocity of the portal it entered rotated to be aligned with the exit portal. You can apply this to make all the other scenarios like the moon work until the cube impacts something else and you need to define some new rules to deal with it. Of course A-fags haven't thought at it enough to realize that.
>>724333214I firmly believe A is just often seemingly more popular because it's like>33% trolls advocating for A>33% useful idiots feeling in good company with A>33% people taking it a bit too serious but knowing it's B
>>724332412You won't see Einstein's relativity affect the box until you have a portal going far beyond the speed that any mass can attain. C is light speed. C^2 is light's speed squared. Kinetic energy formula is approximately 1/2 times mass times velocity squared plus relativity terms which only apply to photons and such in practice.The Portal can't fall fast enough to move the box unless Goku kamehameha's it down with universe creator power
>>724333413B has been winning too much lately so A must be propped up
>>724333553Bro lmaoWe're talking about movement being relativeNot Einstein
>>724333650Forced 50-50 win rate
The cube's momentum is 0 until it passes through the portal, it will hop just a bit because the cube is small and not that heavy.
>>724333995The weight doesn't matter, it just keeps going as fast as it came out of the portal
>>724333798The portal has a mass of 0. Its momentum is (slower than light) velocity * zero. Its force is zero. The box begins to accelerate with gravity as the only vector to which is distorted such that the box doesn't even have full on free fall because it will rotate away much of that free fall energy thus causing a wimpy roll, not an epic launch.
>>724334380Portals don't alter momentum as a function of their own mass or by applying a force lolThey do it by being portalsPlay the games
the real question is what to do about the A "people"
>>724334661Gravity in respect to the portal is preserved.You didn't understand what the game was simulating.
>>724334772Nobody is talking about gravity either. You're so far off the mark here there simply isn't anything sensible to be said about your argument. It doesn't relate to anything.
>>724334750>DBspicDiddly done.
>>724334976You're retarded. Go draw vectors with Chris Chan's sonichu rape simulator instead
>>724332210You've completely failed to account for quantum tunneling
>>724335170The box particles are made of Godchadium and have infinitely strong bonds stronger than suns can burn as molten plasma
>>724335407>bonds stronger than the power of friendship
>>724331731>it uses the same engine/physics as PortalIt does not, since in the OG Portal stationary objects don't pass through portals and instead interact with the surface behind the portal. Which is the canonical answer to OP's question, by the way, but don't tell anyone.
>>724335596>the box particles are not bonded stronger than the power of friendship (per sun squared)
>>724335407Right, par for the course, really
>>724335125M8, they're portals. Here's how they work: you put the cube in, right? And then, get this: it comes out the other. Just like that.>B-but if we take the mass of the portal times gravity divided by C squared, th-the force-You put the cube INAnd it comes OUT
>>724336675>the cube comes out in A and BThat's where you're wrong kiddo. Moving the portal activates the plasma godchadium source code cockblock
>b-b-b-but that's CHEATING
>>724337072What does that have to do with relativity
>>724337545If you violate a fundamental law of spacetime you get plasma exotic energy matter fuckery with all the fundamental forces stronger than gravity going haywire in an indeterminate vector field at the infinitesimal level by shaving the box at integral slices lightspeed teleportations instead of just a hoop jump.
>>724319780i don't need to tell you that you are a faggot, everyone knows that
>>724337924Damn, amazing that they thought to programme all that in the Source engineIt was ahead of its time
>>724337924Needless to say, portals do not work this way. They don't teleport slices by moving them at speeds in excess of the speed of light. They simply let things go through them
>>724338102Bro the Source engine could render Magnusson Devices do you really thought it would struggle with Gauss's law??
>>724338963Then you are only dealing with gravity and none of the other fundamental forces(All of which suggest plasma disaster or in game portal locking)
>>724338965Quantum tunneling, zero point energy... Source is p. powerful
B tards are using collision physics to a non collision
>>724339204We are dealing with portals, Anon. Imagine it in outer space if it helps.
>>724339403Portals do not have forces if they let objects pass through. They would just tilt the free body diagram of vectors as passing.
>>724339505Indeed, they don't impart forces. I told you that already. The cube will simply continue its path, carried by its own inertia.
>>724295164saying the portal transfers momentum means that like if the portal was on a big rock and you threw it at a small object, that the object would come out of the other portal (that was stationary relative to the small object at the start) with a higher velocity than the big rock had, since the momentum of a large object was transferred to a smaller one. But it doesn't matter how big the rock is, the object will only come out of the other portal with its velocity.
>>724330943You hadn't answered my question.>How do you explain why you were able to figure that out and not your fellow Afags?What I'm getting at is it should be a red flag to you that you're sharing an answer with people who aren't smart enough to understand that the moon scene is B to begin with.
>>724340054It's not transferring the momentum of the rock to the smaller object; it's transferring the momentum of the smaller object relative to the portal.
>>724340054Right. The small object would fly out of the second portal with a high velocity given to it by the first portal encircling it
>>724326575100% of sincere A belief is people knowing they wouldn't feel anything if a moving portal passed over them (outside of a gravity field anyway), which is true. But they don't understand that an change in velocity without accelleration wouldn't have any physical sensation attached to it.
>>724292078It has to be an elaborate troll by b fags, like just straight dedicated ragebaiting. I don't even understand what type of education a person would have to get to think it's b, unless they live in north korea or some shit.
>>724341524>I don't even understandYes, that's the problem
>>724335773>Which is the canonical answer to OP's question, by the wayNTA, but could this actually be the case? We see in-game that portals seem to exist slightly on top of any surface you open one on, as opposed to existing at the same plane as the surface itself, so maybe there's some weird technicality that would cause the portal to effectively not work in-universe when moved a certain way.Yes, I know that's a massive reach, but maybe there could be something to it.
>>724341798>I know that's a massive reachIt's not a reach. It is literally how portals behave in the original game when a situation is forced where the portal is placed on a moving platform and slammed against a stationary box. It's as factual as it gets.
>>724341798>>724341941I wouldn't call it "canon" because that would require it to be intentional instead of just an engine quirk. But it's a better answer than A.
>>724341941Yes, in-game, but that's the result of the way the engine is designed to handle portals, not the result of an in-universe explanation as to how the physics surrounding portals actually works. What I'm asking is if there could be some explanation, based on some kind of actual physical law, for the entire scenario simply not working by itself.Because it's either that or A, hands down.
>>724341524>I don't even understand what type of education a person would have to get to think it's bWell an actual education in physics for a start. You do realise we've have multiple people with backgrounds in physics who say it's B at this point?
>>724309578It would be pretty funny if someone took this gif and edited it so the left side is zoomed out to show that they're actually the same scenario. I'd do it if I had any editing talent.
>>724342119>You do realise we've have multiple people with backgrounds in physics who say it's B at this point?Jan Hendrik Schon also had a doctorate, and that didn't make what he said any less wrong.
>>7243396580 inertia relative to the ground
>>724313920That guy who got stuck looping the antlion caves for like 3 hours would probably be an Afag.
>>724342107It's either that or B, actually. Because the problem with A is precisely that if you think it through, it *should* prevent the cube from going through the portal. If the cube is able to go through, it has to be B in order to be consistent.Really, A is the uncomfortable bastard child of the two. It's B until the cube is fully through and then it suddenly can't move.
>>724342107>not the result of an in-universe explanationIt's consistent with Glados's explanation. Speedy thing goes in, speedy thing goes out. If the box ain't speedy, it ain't coming out the other side.Stationary objects don't pass through portals is the canonical answer.
>>724342379That's plainly false. It's clearly moving relative to the ground that surrounds the blue portal.

>>724342473>it *should* prevent the cube from going through the portal.Why, exactly? A portal works like a doorway, it's just a doorway that connects two unconnected points of spacetime. If a portal's being lowered onto an object at a certain velocity, that doesn't just transfer it's velocity to the object traveling through it once it's beyond the threshold of the portal, it would just change the rate at which it travels through the portal itself, but would become stationary afterwards.
>>724320659>Momentum, a function of mass and velocity, is conserved between portalsThe canonical liar lied, shocker.
>>724342840It's not that education is meaningless, it's moreso that even people who are educated in a certain field aren't necessarily all going to agree with each other on the same topics, and therefore being "educated" isn't the end-all-be-all some people say it is.
>>724340326doesn't that imply that relatively smaller things come out of the portal with a higher velocity (along the normal of the portal) than they went into it with? If it doesn't in your mind there's no reason to bring up momentum rather than velocity because however you're thinking the mass terms cancel.
>>724290008Because murderous or not, Glados actually really does value the research and science she does, just for its own pure sake. She would absolutely state confirmed facts at you while trying to murder you
The cube clearly moves through the portal, why should it stop for no reason? To this day I have no idea how someone can believe AAs far as I can tell the retort is always something like>uhh, it's not moving, it's just changing position!!which makes me think Afags are just dedicated trolls, kind of impressive dedication desu

>>724322050No response from Afags. As expected.
>>724342379You don't even know what inertia is.Inertia is a property of mass. An object with no velocity can still have inertia.
>>724343171They think it because there is no experience in reality that involves having your velocity in a single reference frame change without experiencing a force. So they use their intuition about force and velocity in imagining a physically impossible experience and it outputs nonsense.
>>724342945>Why, exactly? A portal works like a doorwayIt doesn't if it prevents things from going through them unless they gave inherent speed - which we've just established is how the engine handles moving portals. So asserting that they are doorways is already making a claim about their nature. So if something stationary must remain stationary, it's not going to come out the portal, because remember, objects are made up of teensy tiny other objects, atoms. And if something isn't coming out, the portals having no "in-between", it's not going in either. That's what A should be.But instead you're speaking nonsense about the cube travelling through at a certain rate and then becoming stationary, which has no logic to it at all.
>>724326190>It's not about a cube falling, it's about a piston pushing downIt's about both because they're identical situations.
>>724343052This graphic is total horseshit, that's not at all what A is in the initial image.
>>724343052It's not exactly a lie; momentum is conserved *through* the portal, and objects going through them experience no alteration. It just looks like a change from the outside. That's the paradox if portals. Momentum is both changed and unchanged depending on your perspective.What trips up Afriends is that when the portals start moving, they flip the perspectives. They try to keep momentum the same if you're looking from the outside, by making the momentum change as seen through the portal.
>>724290280Unfortunately if Afags were intelligent enough to understand this, then we wouldn't be having this discussion.
>>724343498It is A. You just don't realise it.The most common claim made with A is that momentum is always conserved on travelling through portal. The A in that pic is what would happen if momentum actually did stay the same.Portal flings are literally about using portals to change your momentum to cross gaps. Changing direction of travel is by definition changing momentum.
Would you get resistance when crushing something between portals?
>>724343498Well no, in the sense that A really means "I didn't really think about it but this looks good to me". The mistake that image makes is trying to be consistent about A at all.
>>724343731the momentum vector's magnitude remains the same, the direction does not.
>>724343286OMG SEAN LOOK OUTA DOLLY ZOOM MOTION CAPTURE JUST FLEW OVER MY HOUSE
>>724343498Listen Bfags have to be 100% objectively right and if you disagree you're badong
>>724343498Tell us what A actually is. What rule or rules describes what happens to an object when a moving portal engulfs it?B has "relative velocity in = relative velocity out" which is pretty simple to understand and observably works for every situation in both Portal games including the Moon ending.
>>724325373Probably like 80% trolls, 10% newfags who haven't realized it's B yet, and 10% genuine subhuman retards who unironically think it's A
>>724343950It's not really a mistake. The entire point of the image is showing what would actually happen if A was consistent with portal flings.
>>724290809We simply fill the reddit bottle full of reddit juice
>>724343461>which we've just established is how the engine handles moving portals.Yes, how the game engine handles it, because such a scenario never occurs in-game and was therefore likely not considered when programming the portal mechanic. You can also spawn airboats in-game to speedrun by clipping through walls. These are both the result of in-game mechanics, not an intended representation of actual physical laws.I don't have time to try and assemble a video or animation of this or something, so try and imagine a scenario here, maybe this'll get the idea across:We have a cube, floating in space, not moving in any direction. Approaching the cube is a flat panel, with an orange portal on the side facing the cube, and a blue portal on the opposite side of the panel. As the panel reaches the cube, and as the cube passes through the orange portal to the blue portal, the cube doesn't change it's velocity or momentum. It's *position* changes, because the "surface" of one portal connects to the "surface" of the other, but the cube isn't actually *moving* during this process, because there are no physical forces acting on the cube as it passes through the portal, or rather, as the portal passes over the cube.This is why A is the correct answer.
>>724343962Through the portal, it does. In Portal 2 you use moving portals together with lasers. Lasers famously go in straight lines.
>>724344239>was therefore likely not consideredMore likely it was considered and they chose to not feature it.
>>724344073>B has "relative velocity in = relative velocity out"That's not how portals are shown to work in-game, sorry pal. The velocity of the object *as it moves through the portal* is what matters, not the velocity of the portal itself. Again, like a doorway. If I have a door frame dropped on top of me, I don't just suddenly shoot out the other side as soon as I pass through. I have a certain velocity *relative to the door as it falls on me*, but that doesn't mean I'm actually moving by myself.
>>724344239If I read your description right then the cube's position does not change, in fact. You've reinvented a hula hoop. Again. Needless to say, the cube would be moving if the blue portal were anywhere else.
>>724344309Lasers don't go in straight lines. They are photon hoses.
>>724344567>That's not how portals are shown to work in-gameShow me one thing from the game where they don't work like that.
>>724344664They don't go around sudden 90 degree bends, though, do they? The line is straight through the portal. It just looks like a change in direction. The speed is continuous through the portal. It just looks like a sudden launch.
>>724344347If valve ever went through with making moving portals a proper gameplay mechanic would have certainly have put more effort into the implementation of moving portals than they did. It's really obvious the implementation they had was the barebones needed to make the neurotoxin chamber part work.
>>724344606>You've reinvented a hula hoop.Yes, this is how a portal works. Putting the portal on another surface doesn't change the fact that the portal itself doesn't act on the object in any other way than to move it from one point in spacetime to another, and does not add any additional velocity the object did not already have. Whatever physical conditions on the other side of the portal may affect the object, such as a change in gravity, but that's not an effect of the portal itself, and is instead a result of a different environment.
>>724292325You just proved his point you nigger.
>>724344908>six responses to choose from, honed in on the firstDishonest.
>>724290008holy chromosome you are LAYERED in retardation>>724290319B because once the person falls through that portal, they will still move in the direction the object due to its mass moving. youd feel that gust of air carry you in the direction of the object but youd rapidly lose speed and momentum
>>724344895>Putting the portal on another surface doesn't change the fact that the portal itself doesn't act on the object in any other way than to move it from one point in spacetime to another,So you believe the A in >>724343052 then?
>>724344567>That's not how portals are shown to work in-gameYes it is, "relative" doesn't only refer to velocity but also orientation. Portal flings wouldn't work without "relative velocity in = relative velocity out".Not to mention, the moon scene at the end of portal 2 follows B as well.
>>724344895>the portal itself doesn't act on the object in any other way than to move it from one point in spacetime to anotherExplain this one then >>724343882
>>724344895>Yes, this is how a portal worksThat's what you're trying to prove. Fact is, if that blue portal isn't moving along with the orange, you're going to see something different. Any part of the cube that goes in the orange portal goes out the blue. That means if the blue portal is not moving like the orange, the cube isn't going to be doing what you expect. It logically can't.Notice, by the way, that I'm not disputing your hula hoop example. That is in fact how B works in that setup.
>>724290220>>724343094She isn't right though >>724343052https://www.youtube.com/watch?v=ASUUN0W4_JY
>>724344709Show me an instance in-game where a portal's momentum relative to a stationary object causes the object to move by itself after passing through the threshold of the portal.The crux of this argument is the idea of an external force acting on the object, but the problem with B is that there is no external force acting on the object, because portals don't exert any kind of force on the objects that pass through them, and merely serve to connect two different regions in spacetime. The only things affecting the objects that pass through portals are the physical conditions of the environments they travel to/from, not the portals themselves. An object with a velocity of 50 m/s traveling through one side of the portal retains that velocity as it exits the other side, until acted upon by an external force. An object traveling at 0 m/s as a portal passes over it retains that velocity until acted upon by an outside force. In both cases, the portals themselves aren't exerting any kind of force on the object in question.
>>724344073>relative velocity in = relative velocity outHow else could it work?? Imagine if the cube left the portal at 2m/s while entering at 1m/s. So that would mean the total length of the cube is growing by 1m/s??B is dead obvious just from this. The total size of the cube needs to stay the same.
>>724345018>call the person saying glados lies a retard>proceed to give the answer that concludes that glados lied
>>724345414Sadly Afags can't even conceptualize this argument.
>>724345372>Show me an instance in-game where a portal's momentum relative to a stationary object causes the object to move by itself after passing through the threshold of the portal.We've already established tha that's not in the game, but that's not the claim. >The crux of this argument is the idea of an external force acting on the objectThe crux is that portals alter momentum without applying forces - or essentially translate objects to a different reference frame. That's literally what every puzzle involves. An object going 50mph in one direction and then going 50mph in the other direction is twice as big a change as going from 0 to 50 btw.
>>724345086No, because that's not how momentum works. The A in the OP and the A in your image are two different things, and the A in the second image is wrong because it ignores the conservation of momentum, while the A in the OP doesn't. An object retains it's momentum as it passes from one side of a portal to the other, until acted upon by an external force. This is true for A in the OP, as the object has a velocity of 0 m/s on both sides of the portal, as the portal itself doesn't exert any physical force on the object as it passes through it. This is not the case in your image, where A shows an object clearly not retaining it's velocity as it travels from one side to the other.
>>724345598inb4 4d displacement fivehead shows up
>>724345372>Show me an instance in-game where a portal's momentum relative to a stationary object causes the object to move by itself after passing through the threshold of the portal.Literally any portal fling would count as you can just look at the reference frame where the object is stationary and see the speed change on exit.Actually answer the anon's question:>Show me one thing from the game where they don't work like that.You made a claim. Actually back up your claim. But we both know you can't because you don't actually know what "relative velocity in = relative velocity out" means.
>>724345668It is how momentum works. Momentum includes a direction. This is precisely what A's boneheaded interpretation of "conservation of momentum" entails; that is, it actually doesn't conserve shit relative to the portal.
>>724345598That agrees with A, thoughbeit. It's an exploration of why A is correct. The ladder is long, so it would be forced all the way through the portal THEN plop over, just as the cube would. The cube is shorter, so this happens sooner.You'd have to be some kind of retarded Bnigger to not realize this.
>>724345668>and the A in the second image is wrong because it ignores the conservation of momentumThe A in the second image is literally conservation of momentum being followed. You do understand that if momentum is actually conserved the cube shouldn't be changing in travel direction right?
>>724345883>it actually doesn't conserve shit relative to the portal.vector magnitude is conserved
>>724345182>Explain this one thenEasy. There is no space "in" the portals. A portal's "surface" leads straight from that portal's "surface" to the other's, meaning that an object positioned between two portals on two surfaces that have been pressed against each other as such would effectively be crushed, but in a very strange way. It would effectively be made to overlap itself, with all of it's mass existing in the small, finite space between the surface of the two portals. (as in, the area of space where the object resided, not some new space within the portals themselves.)
>>724345663>The crux is that portals alter momentum without applying forcesYes, which they don't.
>>724345939>That agrees with A, thoughbeitBro with this level of comprehension it's no wonder
>>724345968As it is in B, relative to the portal and the frame of reference it finds itself in. Whereas A involves a sudden stop.
>>724345939>so it would be forced all the way through the portalso it moves?>THEN plop overwhy does it suddenly stop moving at the exact moment it leaves the portal? where does the momentum go?
>>724345968Momentum isn't being conserved if only the vector magnitude is. Hell even that will only be staying the same in a single reference frame: >>724337434
>>724346260Right you are. Forgot we were talking moving portals.
>>724346147Indeed, they don't. Chell would've died otherwise, if she had been made to undergo the forces that her changes in momentum would've required under ordinary circumstances.
>>724345939Every rung of the ladder which is being "forced" through the portal has a velocity.When the feet of the ladder come through, the velocity of the ladder has no reason to stop, so it would fling.
>>724345815>Literally any portal fling would count as you can just look at the reference frame where the object is stationary and see the speed change on exit.No, it wouldn't. The change in velocity exhibited by the object in those cases is the result of the change in physical circumstance, not the result of a force being exerted from the portal itself.When an object is falling towards a portal vertically at 50 m/s, and exits from a horizontally positioned portal, it retains that velocity until an external force acts on it, that force being the force of gravity, which would now be acting on it from a different direction than it was previously, causing the object's velocity to change.>You made a claim. Actually back up your claim.You first. Don't pretend your argument's as good as proven just because I'm not doing the same thing you aren't doing.>"relative velocity in = relative velocity out"Man, that "relativity is not a force" guy was right on the money, you really just don't get it.
>>724345883>it actually doesn't conserve shit relative to the portal.The portal moving doesn't matter, portals don't exert their own forces on the objects that pass through them.
>>724344406This kills the Afag
>>724346445>Every rung of the ladder which is being "forced" through the portal has a velocity.>Ok, what is your source for this information?>It... it just does, ok!! It just HAS velocity! I have no basis for this claim but I will build an entire argument on this flawed premise anywaySasuga B-nigger...>>724346259the same reason the cube plops over, anonymous. it doesn't have momentum, it's being translated through the portal, it doesn't move in the traditional sense. kind of like how you should be moving to a library so you can learn basic physics
>>724346445Doesn't matter what version of the concept you try to convey. It's an online argument.
>>724346638You can see the rungs of the ladder moving. You can measure that they travel a certain distance in a certain time. This is a velocity.
>>724346453I'm a different anon that hasn't made any claims to be backed up and I also want to know why you said relative velocity in = relative velocity out isn't how the game works. Even a regular door follows that rule, so I'm curious how you came to the conclusion that the portals in game don't.
>>724346453>When an object is falling towards a portal vertically at 50 m/sNow we shift to the refence frame where the object is stationary meaning the portal is now moving upwards at 50 m/s.In this reference frame the object is stationary before it is engulfed by the portal. But is now moving at 50 m/s sideways when it exits the portal. All within the same single reference frame that we shifted to.>You first. I did (even though I wasn't even the anon you originally asked). Even though you were asked to first. All you're demonstrating right now is that portals DO follow "relative velocity in = relative velocity out", because you've failed multiple times to prove otherwise.
>>724346638>it's being translated through the portal, it doesn't move in the traditional senseevery time lmao>i-it's not moving, it's just changing position!!I wonder what Afags think movement is.
>>724345943>You do understand that if momentum is actually conserved the cube shouldn't be changing in travel direction right?Good god, how to begin.The object's *velocity* is conserved as it travels through the portal, not the *trajectory* of the object. As the object passes through the portal, the object goes from traveling in a downwards trajectory to a horizontal one, and the object's velocity combined with the new angle of travel, as well as the fact that the force of gravity is now acting on the object from a different direction than it was before the object passed through the portal, cause the object to travel in a new trajectory. Think about that image for a second, why would the cube just plop out of the exit portal if it had all that momentum beforehand? That image is deliberately designed to misrepresent the actual argument here by confusing people who don't understand the laws of physics, like you.
>>724346453>You first.Bro you're not even getting it lmao"relative speed in = relative speed out" isn't just observably true of every portal interaction in the game, it is *necessarily so*. You ask for proof: play the damn game. You're the one who said it doesn't work like that. Very well, provide just one example and you'll have disproved me. But you can't. Not just because portals work like that in the game, but because they wouldn't work otherwise.
>>724346772They move through the portal instantaneously, retard-sama. Are you suggesting they have infinite velocity in the course of that movement?>B...b.b...but the rungs on the other side of the portal are being moved as the rest of the portal comes through!!!That is correct, but they are not inheriting momentum from this "movement" because it occurs via the portal translation. I hope I don't have to explain to you that such a movement is not possible in the real world and thus your childish attempt to apply real word logic to it is painfully shortsighted. They are certainly also not being compressed as you have originally suggested in your infinite retardation

>no momentumreally ought to be able to have a bot run these threadsif they aren't already.
>>724346864>relative velocity in = relative velocityThe keyword here is "relative". The only instance we see in-game of independently moving objects interacting with portals, is when a moving object passes through a stationary portal, not the other way around.We know that portals conserve the momentum of the objects that pass through them, whether that be 50 m/s or 0, from playing the games and hearing Glados describe the portal's mechanics.The only velocity that matters in this problem is the velocity of the object, not the portal. The portal, by virtue of simply translating an object from one point in spacetime to another, effectively isn't moving at all, because all it is is a bridge from one point to another, and not a defined location/object in and of itself. It doesn't exert any forces on the object that passes through it, only the different environments on each end of the portals do.
>>724329208They literally said "In game, it's A". We won.
>>724347669>The only velocity that matters in this problem is the velocity of the object, not the portalThat makes no sense, the object needs to leave at the same rate it goes in. That's a fundamental principle needed for portals to make sense at all.
>>724347669>The keyword here is "relative".Yes. You do know what it means, right? Just answer the damn question. Does the cube at any point in the game not have the same speed relative to the portal upon exiting as it did entering? Yes or no?You're avoiding this for some reason.
>>724347851That's the one part they got wrong though
>>724347212Yes, yes, now respond to the rest of the argument, unless semantics are the only counter you have.You get my point, the reason why the object travels along a different trajectory after passing through the portal is because the portal causes the object to be oriented a different way as a result of how portals connect two different regions of spacetime. An object traveling in a downwards trajectory before entering a portal with a horizontally positioned exit portal doesn't continue along that trajectory as it passes through the portal, otherwise it would continue moving downwards and hit the rim on the other side. Rather, it retains it's speed, and passes through the exit portal with a new trajectory as a result.
>>724347669>The only instance we see in-game of independently moving objects interacting with portals, is when a moving object passes through a stationary portal, not the other way around.Which still means you can make claims about the moving object's motion relative to the stationary portal.Can you actually name a point in the game where "relative velocity in = relative velocity out" isn't followed?>We know that portals conserve the momentum of the objects that pass through themThey don't by the very nature that the portals are shown to change the travel direction of objects. That's what >>724343052 is pointing out.At best it can be said that the momentum is conserved only in the sense of between the two reference frames of the two portals which is the very thing "relative velocity in = relative velocity out" is describing.
>>724347669No matter how you measure velocity in game, the velocity they enter relative to the portal is still equal to the velocity they exit relative to the portal. It is easier in game since the portals aren't moving so 50 m/s relative to the level is also 50 m/s relative to both portals. It enters at 50 m/s and leaves at 50 m/s. 50=50. It is ok to just say you got over eager and said something you didn't actually mean to say on the way to getting to your actual argument.
>>724343286that retard believes in many worlds lmao
>>724347983>Does the cube at any point in the game not have the same speed relative to the portal upon exiting as it did entering? Yes or no?I already have. In-game, in the actual campaigns for portal 1 and 2, we only ever see an object exit a portal with the same velocity with which it entered, until acted upon by an external force. It happens when you drop a cube, it happens when you do a portal fling, it happens every time.Because only the object matters, not the portal.
>>724347669In every single portal interaction in the games, B's rule of relative velocity conservation applies.In every single portal interaction of the game, A's rule of absolute speed conservation applies EXCEPT for the moon scene.So B's rule is a better way to describe observed canon portal behaviour.
>>724346445>velocity of the ladder has no reason to stop, so it would flingwhat force is acting on the ladder to fling it?
>>724348297Anon, yes or no.
>>724348239>No matter how you measure velocity in game, the velocity they enter relative to the portal is still equal to the velocity they exit relative to the portal.Yes, because all portals in-game are stationary except for the laser scene, and the velocity of an object relative to a point that isn't moving is the same. My point is that relativity is irrelevant here, because the portals never exert their own forces on the objects that pass through them, because that's fundamentally not how portals work.
>>724347958Just FYI it wouldn't come out at 1m/s and "speed up" to 1000m/s, it would enter at 1m/s and on the other end 1m/s of cube would come flying out at 1000m/s. How that would look like is determined by what the object is made of but think spaghettification from a black hole.
>>724348338>In every single portal interaction in the games, B's rule of relative velocity conservation applies.Explain how.
>>724348359There is no force. The ladder emerging from the portal has a velocity relative to the exit portal because it had a velocity relative to the entrance portal.What force would instantaneously stop that velocity as soon as the feet of the ladder emerge?
>>724348502>My point is that relativity is irrelevant hereIt necessarily applies>the portals never exert their own forces on the objects that pass through themAnd yet they change their momentum anyway. So I guess forces *are* irrelevant here.
>>724348587If a cube falls in to a portal at 10m/s relative to the entry portal, it emerges at 10m/s relative to the exit portal. The direction of the velocity is also conserved relative to the portal, which is how flings work.
>>724348492I literally answered the question in that post.>we only ever see an object exit a portal with the same velocity with which it entered, until acted upon by an external force.If you can't see the answer when I've written it so plainly and clearly, no wonder you don't get it.
>>724348519Alternatively, it just comes out at the same relative speed and remains perfectly intact because a portal is just a hole
they just do
>>724348664>And yet they change their momentum anyway.Yes, because of the change in physical forces brought on by the conditions on the other side of the portal, not by the portals themselves.

>>724348338>In every single portal interaction of the game, A's rule of absolute speed conservation applies EXCEPT for the moon scene.This is actually not true if the Earth is moving. You throw a cube into a portal on a wall and it goes in at really fast minus 1 and it comes out of a portal on the same wall as really fast plus one if you are measuring the speed based on some center of the universe. It is just like a really big and fast train.>>724348502If that is your point then you should really try to avoid making statements that are clearly wrong and also irrelevant that will derail the argument. It is ok for that statement about relative velocity to be true without hurting your argument.
>>724348716Yes, precisely.This is why an object with a velocity of 0m/s *also* retains it's momentum.
>>724347669>The only instance we see in-game of independently moving objects interacting with portals, is when a moving object passes through a stationary portal, not the other way around.The literal definition of the word relative states that there's no difference between those>portals conserve the momentumFalse.See >>724343052>The only velocity that matters in this problem is the velocity of the object......relative to the portal, aka the velocity it's entering and thus exiting at. And also the velocity it will continue moving at after it's done exiting because there's no force to stop it.
>>724348738I'm going to take that as "no, there is no point in the game where the cube does not have the same speed relative to the portal upon exiting that it did when entering." Which is the correct answer! Thank you for conceding.
>>724348716they how does a cube enter at 0 m/s relative to the ground and come out flying away from the ground?
>>724348908you wanted this one
>>724349002Because velocity is conserved relative to the portal(s), not the ground.
>>724348105>Yes, yes, now respond to the rest of the argument, unless semantics are the only counter you have.It's not semantics. Velocity and Momentum have very concise definitions. Which matters because it means the claim that portals conserve momentum is not actually true.>Rather, it retains it is speed, and passes through the exit portal with a new trajectory as a result.That's the thing though. Because the velocity and momentum aren't actually conserved that means the claim that even speed is conserved becomes very frame dependant. See >>724337434.Basically an object's speed is only retained on passing through the portal when looking at the reference frame where both ends of the portal are motionless. Which we clearly aren't looking at in the original problem since one end is moving.
>>724348769Correct. That's what would happen with A. B is the one where it magically gets flung out like pictured here >>724347958Not sure why that anon claims it shows A though. Probably just the usual Bfag retardation.
>>724348817>because of the change in physical forces brought on by the conditions on the other side of the portalNo you daft bint, because of the orientation of the portals. It's *entirely* attributable to the portals and nothing else. They're all in the same fucking environment under unchanging conditions, if there were no portals there you'd just be tossing a bunch of boxes around you twat.
>>724348906
>>724349049>just making up ways to violate physics that justify how retarded you are
>>724349042I never understood why people make these but swap the A/B from the original A/B.B is correct in that image which lines up with A from the OP image which lines up with what is expressly shown to us in portal 2.
>>724309538>plopIt's the extra stuff like that that gets me laughing.
>>724348906>9.8 m/s^2>instantaneous
>>724348947>The literal definition of the word relative states that there's no difference between thoseThat's the problem, there *is* a difference between those two in this context because of the nature of how portals actually work.Portals don't imbue the objects that pass through them with any physical force of their own, only retaining any force they had. A portal is a nothing but a bridge from one point in spacetime to another, so suddenly slamming the threshold of a portal down on something at a given speed does nothing but transfer the object from one point in spacetime to another, at the rate at which the portal moved down on it, but not giving it any extra momentum of it's own.Meaning, if I slammed a portal down on a cube at 50m/s, the cube would emerge from the exit portal at that same speed, but then simply remain stationary at the mouth of the exit portal, because that's what the cube always was.Stationary.
>>724349124>That's what would happen with ANo bruv. You've got it exactly backwards. But that's the thing: you don't know what A or B actually are. None of you do. You just go by vibes. You vibe with B in this scenario, so that's now A to you.
>>724349216Every single one of them parodies the A claim that speed doesn't change.
>>724349216B in that image lines up with B in the original which is explained as Relative velocity in = Relative velocity out.
>>724348958>no, there is no point in the game where the cube does not have the same speed relative to the portal upon exiting that it did when enteringExactly, that's why A is correct, I'm glad I finally got through to you.
>>724349181Portals already violate conservation of energy and a bunch of other stuff. Conservation of relative velocity is just an observable rule of how portals function that works every single time. There's no other theory of portal behaviour that actually explains both the moon scene and all the standard interactions, that's why you see Afags either pretending to not understand the moon scene, or making up their own bullshit that it's a FAKE MOON THAT DOESN'T ORBIT THE EARTH.
>>724349216They aren't swapping A/B. You're just noticing A's logic doesn't work but failing to realise it's A's logic.
>>724309538If I pull your dick, will you die?
>>724348945An object moving at 0 m/s relative to the portal will never enter the portal.
>>724349181It's logically the only thing it can do, because the alternative is that the cube exits the portal either before it has gone entirely in, or after. No, it necessarily must be exactly the same, relative to the portal.
rel vel in = rel vel out is undefeated
>>724349392"True" velocity in = "true" velocity out. if it were "relative" based on the portals, you'd get flung out. you don't get ripped to shreds when you come out on the moon = A in the OP (and B in the globe model) is correct.I genuinely don't understand why you guys pretend to be retarded lol.
>>724349042That too, but even portals in the same room only conserve speed relative to the portal. even portals stationary relative to each other break conservation of energy if you consider some absolute speed.
>>724343171>The cube clearly moves through the portalYes it does but its stationary. You would have to throw it into the portal for it to be B.
>>724349330>don't imbue the objects that pass through them with any physical forceExactly! Which is why the cube keeps moving as there's nothing to stop it. I'm so proud of you for finally getting it :)>transfer the object from one point in spacetime to another, at the rate at which the portal moved down on itSooooo.... Movement?>the cube would emerge from the exit portal at that same speed, but then simply remain stationary at the mouth of the exit portalWhat force causes it to instantly decelerate to 0?>that's what the cube always was. >Stationary.There is no such thing as stationary by itself. Only relative to something.
>true velocityit's not even bait at this pointsee you next thread
>>724349596There's no such thing as "true" velocity in real life. That only exists in games.
>>724313894Aonly attractive women are allowed in
>>724349330No. You're almost there but you're still clinging to A for some reason.>if I slammed a portal down on a cube at 50m/s, the cube would emerge from the exit portal at that same speedThis is correct >but then simply remain stationary at the mouth of the exit portal, because that's what the cube always was.This is pure nonsense.Motion is relative, you've already described the cube actually being in motion, at this point it would need a force to *stop* and there isn't any.>But what force caused it to move out of the portal to begin with??I dunno, same force that makes portal flings work in the game? The cube experiences no force though, it feels it as continuous motion, which is to say, it doesn't.
>>724349425wtf does the moon scene have anything to do with it in the first place>open portal to the moon>suddenly experience an opening to the vacuum of space>pulled into the portal at some velocity do to pressure differential>continues through the portal at this velocity>somehow this has anything to do with an entirely different scenario where a portal travels over a cube (which can't happen in the game), the cube being at rest
>>724349913Hence the quotations. If the speed RELATIVE TO THE PORTALS mattered, chel would be obliterated coming out on the moon. the second one leg comes out at thousands of meters per second in a different direction than her torso, she's a fine mist.That's not what happens in game because it's not about the portal's "reference."Hoop.
>>724349405Except that is literally the principle that B operates under, the one you claimed waa disproved by the game, which you now quietly walked back. Now you suddenly think that's A huh?
>>724349989The moon travels sideways at 1km/sChell inherits that velocity when she passes through the portal.>>724350039Literally the opposite. Relative velocity conservation means that Chell doesn't experience the 1km/s velocity across her body.
>>724349596>if it were "relative" based on the portals, you'd get flung outNo. You simply exit the other portal in a continuous trajectory. That's what relative means.
>>724349596>if it were "relative" based on the portals, you'd get flung outNo, unless you don't actually know what that means.
>>724349989
>>724350085>Chell inherits that velocity when she passes through the portal.that's literally not what happens
>>724350039>go in at 10m/s relative to the portal (and the earth)>come out at 10m/s relative to the portal (1km/s relative to the earth)That's B, and that's what we see in game
>>724350193Literally fucking watch nigga >>724350140
>>724349805>Which is why the cube keeps moving as there's nothing to stop it. I'm so proud of you for finally getting it :)Not right! As the portal doesn't imbue the object passing through it with any physical force, the object doesn't move once beyond the threshold of the portal, with it's "movement" from one end of the portal to the other simply being the translation from one point in spacetime to another, not the result of any actual movement on the object's part.>Sooooo.... Movement?Nope! Translation. Like teleportation, but less of a snap. Think like that teleporter gun used in Gantz, but faster and less gross.>What force causes it to instantly decelerate to 0?It's not decelerating, it wasn't moving to begin with. The object's momentum is retained, and that momentum is 0m/s. Conservation of momentum would be violated if the object was moving, because that would mean the object is moving without any force having been exerted on it.>There is no such thing as stationary by itself. Only relative to something.Whatever you wanna call it, the fact of the matter is the object isn't moving on one side of the portal, and still isn't moving on the other side.Momentum is retained, A is correct.
>Afags pretending not to understand the Moon scene again
>>724350193>that's literally not what happensIt literally is. You notice that chell is still with the moon on the other end right? That means she's inherited that velocity to be moving with the moon.
>>724350205>go in at 0 m/s relative to ground>come out at 0 m/s relative to ground>plop on the ground literally A
>>724350317That is AThat is also inconsistent with the moon scene
>>724350305she would have become paste as every atom came out if she inherited that velocity.
>>724350267You're using words but you don't seem to really regard their meaning
