Shouldn't someone have time-traveled back to our time by now?
why the fuck would you go to this era
>>110220220Imagine being an alien, traveling 60 million light years to see cool dinosaurs, but arriving to see jews instead.
>>110220220I think time travel is real but you can only either send back information that we're not advanced enough to intercept and decode yet, or it sends you to a parallel universe that is exactly the same except the time is different, and nothing you do there affects your parent universe when you return.Either way it's functionally the same
They traveled already to the 90's because those where the best times
>>110220238you'd rather they wait?
>>110220220Isn't there a theory that time travel requires the right technology to exist at both ends, so you can't travel to a point before a working time machine has actually been invented?
The fascinating thing about Terminator is that the timelines are already stuck in a loop by the time the first movie begins.Skynet doesn't get built if Terminator 1 (built by Skyney) doesn't go back so his chip can be studied by cyberdyne (who built Skynet)
>>110220375That and John Connor doesn't exist unless Kyle goes back in time and impregnates Sarah.As for the overall question, how do we know they haven't? Maybe they want things to turn out how they are right now. How would we know if there are time travelers here right now manipulating things? Why would we think their goals would be anything like our own?
>>110220274All according to plan
>>110220220then you create another universe, which may end up killing everyone in the past. time travel doesn't solve anything. also play tower of fantasy until the china region where it turns from kino to shit.
>>110220220No, because it's impossible.
>>110220350I think it's related to wormholes or something. Wormholes are theoretically possible, and are subjected to relativity like everything in the universe is, so you take one half and you accelerate it or put it near a black hole, and then bring it back; time has passed slower for that half of the wormhole than it did for the first wormhole, so you step through the wormhole that has experienced the time dilation (the one you took with you), you should theoretically come out the other side in the past.But you can only come out in the past *after* the wormhole was first created. So 10 years has passed for the time dilated wormhole, and 100 years has passed for the original wormhole. You can only come out in the past 90 years ago, 10 years after the original wormhole was created Whether or not that somehow fucks with causality, idfk. Like if you go into the past and then shut down the wormhole, wtf happens? Provided you even *can* shut down a wormhole. And wormholes are entirely theoretical still, we don't know if they can actually be big enough to send substantial amounts of matter through whatsoever without requiring infinite energy.I'm barely conscious right now so some /sci/ fag correct me if I'm explaining it incorrectly
>>110220220any time there is someone (on this timeline anyway) makes a statement that they are a time traveler, they need to make a movie out of it as a form of post hoc plausible deniability
>>110220220I traveled just now, AMA
>>110220350Primer explains the only plausible time travel approach
>>110220220>time-travelersThey're all in jail for noticing that our History books are full of lies.Seriously, would you expect our masters to let time-travelers tell us the truth?
>>110220220great inventors are all time travellers
No
>>110220220>Shouldn't someone have time-traveled back to our time by now?A few of us did. We accelerated AI for the lolz.
There is no future.

>>110220220They operate in secret, without putting history at risk, they make only precise cuts.
>>110220929Butterfly effect go brrrrr.
>>110220220time == entropy you cannot reverse it you can only speed it up
>>110221040grok make him altman
nothing, even time, matter, or energy, is real. we are in a simulation and have no idea of the horrors beyond.
>>110220350(Backwards) time travel is likely fundamentally impossible for the same reason traversable wormholes are, quantum mechanics.Even if we're wrong about literally everything we don't have observational evidence for and need to redo QM from scratch quantum fluctuations mean in any realistically achievable environment the energy build up leads to a near instant black hole.Frankly a naked singularity is more feasible to achieve in our physical plane of existence than a time machine or wormhole is.Sorry to say QM is the biggest fucking party killer because a naked singularity is in all likelihood also impossible, there's just slightly more theoretical wiggle room which means jackshit frankly.
>>110220929how did he know about the orange man in 2006?>first nuke didn't kill anyonewut
>>110220451>>110220375>humans and machines both get stuck in the same timeloopso the message is that we are both the same? terminator is just blade runner?
>>110220965No the apparent direction of time is entropy
Cyberdyne finds arm & chip in 1984
>>110220522>Muh relativity!!!Dunning-kruger ahh redditbrained midwit kek
>>110220538how is it when you fart, go back in time and fart again to smell it?
>>110221610Incredibly painful.

>>110220522wormholes dont work because you need exotic matter to hold them open, you can't cross them before they closephysics likes to troll people like that
>>110220220They did go back.You just never realized it.They DID alter the timeline.You just need to find out where
>>110221167>for the same reason traversable wormholes are, quantum mechanics.that's not the reason that traversable wormholes are impossible though?
>>110220220maybe they have invisible cloaks in the future?
>>110221863>there can only be one reason at a timeAlso yes. Yes it is.
>>110221930Why does QM make them impossible? Because of the energy density or something?
>>110220552but primer had the mechanic that the boxes stacked, and black haired guy literally went back to before the invention thats why he was bleeding after going through once, he already had been through dozens of times trying to stop the shooting perfectly idk how that movie is so hard for people to follow
