I was surprised there wasn't a thread for discussing quantum mechanics already. So I made one.Let's exchange our thoughts surrounding quantum mechanics.I'll go first:I was checking material around the double-slit experiment, again, trying to wrap my head around it, and found something I didn't noticed the previous times.> Photons act as a wave in the electromagnetic field and transmit their energy as a particle.This made me think about a ton of stuff but here is the short version.The classic example to illustrate the interference pattern is water waves. But water waves are made of water molecules (Go figure) and the reason they produce waves it's because of the interaction between water molecules as part of one thing. Shoot two streams of water through both slits and you won't get any interference patterns.Could it be that the interference patter with the photon and electron versions is because there is just a unaccounted discrete interaction and not the "the particle passes through both slits at the same time" explanation everyone gives?My guess is that when a photon passes through a slit, its electromagnetic field alters the electromagnetic fields of the slits and that affects the next photon that passes through, bending it's path in a uncertain way.The part that it's still a bit fuzzy on my mind is how does this explanation fits with the scenario where the path of the photon is known and the interference pattern disappears.
>>17069476Your interpretation isn't far off from Pilot Wave Theory. Basically the answer to the "fuzzy" part of your interpretation is that available paths exist in a higher dimensional space so the (still deterministic) wave does take on a different geometry depending on what information about that path is available in the visible dimensional space. We just don't see that structure here in 3D. (I am greatly oversimplifying in a way that would piss off a lot of physicists. But this is sufficient to answer your question. There is no shortcut to doing and understanding the math if you want a complete picture).But honestly, this is really no simpler than Copenhagen. A "particle" is just the minimum energy level at which a field is capable of interacting with something. Until that interaction occurs, there is no particle to "go through both slits." It's just a continuous wave of energy dispersed across the field. Obce the interaction does occur, the minimum energy for the interaction to occur must come from somewhere so it's "leached" from the entire wave.
>>17069497Regarding the Pilot Wave Theory. Definitely I have to dive into the math to understand it but here is what I got. Tell me if I'm wrong.> Wave = Particle> The path taken is deterministic but defined by the available paths> The available paths are expressed as multidimensional vectors> The effects observed reside in out observable dimensions> The changes on the observed effects are explained not by the particle taking multiple paths at the same time but by traversing one of the available multidimensional vectors / paths
>>17069516> *The effects observed reside in our observable dimensions> The path taken is deterministic but defined by the available pathsSomething like a ball rolling across a multidimensional surface, where the ball can't roll outside this surface.
>>17069516> Copenhagen: uncertainty is in the particle, easy and simple to perform the calculations.> Pilot Wave: uncertainty is in the wave, hard and cumbersome to perform the calculations.Both make identical experimental proven predications and give the same final results from the math. So in that regard they are both unfalsifiable despite being completely opposing interpretations - in fact the same is true for all QM interpretations.
>>17069516"Wave = particle" is wrong under pilot wave. According to the theory: there is always a particle. And the wave more or less represents a set of force vectors guiding the particle.Describing available paths purely topologically was kinda the part that would piss off any knowledgeable physicist. It lives a bit more in an "abstract" realm of "configuration space." When information is known about possible paths, that removes possible configurations from where the set of force vectors could be pointing.To confuse matters more, there's a concept floating around that if you take modern pilot wave to its logical conclusions, it's no different from many worlds (which is the interpretation popsci rags often mischaractarize as meaning there's literally alternate realities parallel with our own). It's a debatable viewpoint but it does highlight how much the concept of a deterministic wave "guiding" particles has to be contorted to match observed data.
>>17069533Here is what I got:> "Copenhagen" and "Pilot Wave" are both different theories that represent different interpretations> Although these both come from different interpretations, both produce similar enough results and predictions.> Because of the way both theories interpret the data, saying that a wave is a particle is not the same depending on the theory> Copenhagen says: the wave is the particle> Pilot Wave says: the wave influences how a particle moves
>>17069549>both produce similar enough results and predictionsnot similar, identical. that's why there's all this confusion and bullshit spoken about QM, you can't prove any of these alternative ideas wrong (or right).
>>17069549Much closer. As another anon said: all present interpretations of QM observe the same exact outcomes so any distinction between them is purely ontological/philosophical until a differentiating experiment can be conceived and demonstrated.With Copenhagen, it's not so much that the particle "is" the wave and more that a particle isn't even really a "thing." Much like how a "volt" describes a quantity of energy rather than a physical object, a "particle" is just the minimum quantity of energy for an interaction to occur in the associated field.But yes, pilot wave does, indeed, reify particles and waves both as distinct entities.
>>17069533The fucked up part here is, if I build a macroscopic gutter which accurately represents the "warm EM" field OP is considering, it won't remit aether or make quantum duality easier for people to understand, it will just make everyone think we can model discrete information using mere intuition rather than actually needing math.It doesn't matter if an enlightened monk can will the framegate open a few extra seconds to get some stragglers through, relying on a siddhi for your wormhole services is NOT gonna pass for the competent and right solution.
regardless of interpretation it is clearly think that the quantum state objectively does no more than carry information about probabilities. its very easy to go into detail how this is exacyly objectively the case. this doesnt help interpretation but rules out all ontological interpretations like objective collapse and many worlds, the latter of which is internally inconsistent and therefore impossible anyways. imo the only true problem in quantum theory interpretation-wise is bell violations because you have to choose between nonlocal bullshit or completely unsatisfying nonreality
>>17069476The photons are not all that well described in standard QM. The space wave function is not the same thing as electric field. A complete description of everything is done only in QED.
>>17069476A very early example of your line of thinking is the thinking of Planck and other statistical (or thermodynamics) physicists who lived in around 1920. The idea was that, let’s say in the context of the double-slit experiment, that the electrons (or whatever particles) were basically a field that would propagate around like water waves, but that the interaction with matter was intermediated by discrete exchanges. So the discrete electron was just a relic of the transferring of energy from the electron field to a different medium. But electrons didn’t inherently have a particle nature during their pass through the slits, instead it was a wave field up until the interaction with the detector.Einstein was the one to refute this logic in his paper about photons and the way the statistics of photons imply the must have some bosonic nature. The statistical properties of how photons behave imply some behavior of their wavefunctions and how those wavefunctions correspond to a system of bosonic particles.But if you step back and look at this from a more modern perspective, i.e. the perspective of Quantum Field Theory, really the idea that things are fields all the way down is not all that radical, and then the way electrons interfere is pretty much what one would expect. The details of bosonic/fermionic vs. identical classical particles is the hinge thing to worry about, and really what that shows in this context is how the fields behave in terms of quantum exclusion, state occupancies, and statistics. So from a truly modern perspective it is quite acceptable to just say it is all fields all the time (akin to waves in water), they are just “quantized” meaning the fields observe the *statistical* rules of quantum bosonic/fermionic fields
>>17072319PS there are a bunch of “Pilot Wave” shills here who would like to enact Bohm’s Marxist Material Determinism Dialectic or some woo-woo modern zombie version of it, but these folks are basically brainwashed internet groupies of a few California Marxist Hippie Commune people who contaminated the early internet with a bunch of propaganda; don’t listen to them. they should snap out of it and realize that they are talking into the wind for decades and anyone with a real physics education has realized they are retarded for like 40 years. Bohm just spent a lot of time at Esalen and in Ojai with Ramamurti so a bunch of New Age boomtards got tricked into his Marxist delusions
>>17072321>RamamurtiSorry, I meant Krishnamurti.If you want to see how retarded Bohm was you can find videos on youtube of Bohm asking Krishnamurti about physics. Krishnamurti obviously knows nothing but rambles with sophistry in your typical jeet charlatan way, and Bohm, the supposed genius physicist, just rides his dick constantly like “omg Krishnamurti that’s amazing you are so good at physics”. pathetic
>>17072221>>imo the only true problem in quantum theory interpretation-wise is bell violations because you have to choose between nonlocal bullshit or completely unsatisfying nonrealityYou can also go for "nonlocality" in time aka non-Markovian quantum mechanics. An event that happened billions of years ago has absolutely no influence on a particle until suddenly it does
>>17072332yes im not sure about this notion. it is quite vague what it actually means. fits a broad umbrella potenttially of odeas that fit "temporal non-local". whereas spatial nonlocal hidden variable very easy to understand what neans
>>17072221>imo the only true problem in quantum theory interpretation-wise is bell violations because you have to choose between nonlocal bullshit or completely unsatisfying nonrealityyou actually don’t… Have you read what Bell wrote about Bertlman’s Socks? Have you read the relevant chapter in The Quark and the Jaguar where Murray Gell-Mann explains the real version of Consistent Histories (before Hartle got off track and turned it into some bastardized version)? You don’t need nonlocality nor non-“realism” to explain Bell’s theorem experiments. All you need is a version of Bertlman’s Socks that admits that quantum variables (like spin) are not the same as classical variables. No superluminal signal propagates. The particles are created in a correlated state and the outcome is determined from how their state was when they were created (Once you see Bertlman’s left sock is one color, you know instantly the other sock is a particular color. No superluminal signal needs to happen.) The fact that spin variables have unusual properties does not imply anything about realism or locality except that quantum variables like spin don’t agree so straightforwardly with classical ideas of “realism”I posted extensively here about consistent histories like 10-8 years ago but the perennial confusions always crop back up. It’s sad that people don’t read Gell-Mann’s book
>>17072931>the outcome is determined from how their state was when they were createdLike a hidden variable?
>>17072981No, a “hidden variable” refers to something that is not measurable. In this case the spin variable is the relevant variable, and it is measurable
>>17072982But in what way are they different than classical variables?>Once you see Bertlman’s left sock is one color, you know instantly the other sock is a particular colorYeah but they don't have a defined color that we just don't know (hidden variable) prior to measurement so some non-local stuff has to happen to give them both a color
>>17072988>they don't have a defined color that we just don't know (hidden variable)>some non-local stuffPick one and only one. If "non-local" stuff is acceptable, you can have non-local hidden variables.
>>17069497>>17069476pilot wave is such old debunked boomer bullshit. in fact if a QM discussion goes on for more than a few minutes without anyone mentioning QFT it's probably loads of bullshit. idk who is funding the popsoy channels to keep ancient qm debates going and to avoid just talking about QFT>>17072321holy never listen to this schizo
>>17073148It's not that clear cut. There has been work done that makes PWT (mosty) work with QFT. It's ugly as fuck though.
>>17069476>Photons act as a wave in the electromagnetic field and transmit their energy as a particle.Light transmits as a continuous wave until absorbed as a small chunk of energy by some bit of matter. When light is traveling through space, it is a continuous wave at all times. It is not a bunch of "photons" traveling together looking like a continuous wave. It is infinitely divisible. Ok, well at least divisible until the wavelength gets so long that you can't distinguish it using any "measurement" to where it's practically zero. Light can be emitted as a small chunk of energy by a bit of matter, but once it's traveling through space, it's a continuous wave.
>>17073021>If "non-local" stuff is acceptable, you can have non-local hidden variables.Yeah but according to you we don't need non-locality to explain Bell's inequality
>>17073152Not only is it "ugly as fuck." The modifications to pilot wave have rendered it nearly identical to many worlds.
>>17072988No, like I said before, if we interpret Bertlmann’s socks in in the proper original Consistent Histories picture, then his socks had a definite color from the instant Bertlmann put them on when he got dressed that day. If we are talking about quantum spins, the outcome of what you would see when you look a spin along the x, y, or z direction is encoded into the spin when it and its pair-produced spin-nonzero particle is encoded into both the particles when they are created. The fact that they are represented as an “indeterminate” state is simply because these are quantum variables and that’s simply how quantum variables work. But the way you get perfect (anti-)correlation across space like separated distances when both particles spins are measured along the same axis arises from the fact that they were (anti-)correlated from when they were produced. Nothing nonlocal, it’s just that you anre mistakenly trying to interpret [(up1+down2)+(down1+up2)]/[sqrt(2)] as a classical thing. Just accept that it is a quantum variable and that does not mean it isn’t fully (locally) encoding anticorrelated measurements from the production of the particlesRead Quark and Jaguar, please. The relevant section is a short 4-5 page explanation and it’s written by one of the greatest physicists of the last 100 years. You can find it screenshotted in the archive of this board on warosu.org. You can search “Flapdoodle”
>>17073346>Light can be emitted as a small chunk of energy by a bit of matter, but once it's traveling through space, it's a continuous wave.and that doesn't sound weird at all. I mean I'm not saying it's not real, just that it's weird. like seriously weird. like everything you've ever seen as fantasy or scifi but ^1000^1000^1000 more weird and strange.or the fact that we even fucking exist. like what the fuck is this and why??
>>17072931i mean this is menaingless unless you explain exactly what these non-classical variables are and how they work. if you could do that then resolving bell's theorem would no longer be an unresolved issue ... but it still is unresolved. you dont have a coherent alternative that doesn't fit into categories like nonrealism or retrocausality
and to be clear in my view i think non-realims is still non-local. but i fink that non-realism allows you to avoid violating relativity. tae do this you need retrocausal influence (or perhaps you might call it non-causal, linked to time-reversal invariance). but if you dont have reality "retrocausality" isn't really a problem anymore because even if you frame causation as retrocausal or non-causal, you have no underlying hidden variables that actually need to change
>>17073536Actually transmitting a photon doesn’t really need to be done as a “small chunk”. If you think of a big antenna, or even better if you think of a black hole emitting hawking radiation, then that sort of emission doesn’t really admit a QFT description where a photon is popping off of one particular atom. In QFT you would model that as some extended, macroscopic object pumping energy into an extended “boundary region” of the QFT description and causing various photon “modes” to get excited over that entire extended region. And on the absorption side of stuff like this (like a big antenna to detect radio waves, or a very big photodetector without any granular pixels) you would also probably have a similar thing where the appropriate model considers that interaction/measurement using an operator that is spread out over a macroscopic areaIt is good to think a bit about how the formalism of scattering theory in QFT works. The micro-physics, usually described using Feynman diagrams to do perturbation theory, does break things down as point particles interacting at discrete points in spacetime (and then superposes them in the path integral). But that is just the matrix-element part of the S-matrix calculation. The S-matrix also has the amplitudes travelling off “to infinity” which basically means your large macroscopic detectors, so that’s implicitly a part of QFT as well
>>17073545I don’t think there is anything in my explanation that differs from the variables you see in an ordinary Intro QM textbook. Just ordinary wavefunctions. The point is that your thinking is getting fucked because you are trying to retrofit your understanding of classical variables onto ordinary wavefunctions. The formalism gets it right but classical intuition can’t be used. Quantum variables are just different. I think this boils down to questioning the definition of “real” or “realist” means in the usual Bell dialogues. In a good Consistent Histories interpretation there is a concept of “locally realist” but it doesn’t map neatly onto what classical realism à la Einstein/Podolsky/Rosen had in mind
>>17073564well this is meaningless if you dont know what the wavefunction means. this will mean different things depending on your interpretation. in a naive realist wavefunction framework this is still non-local
>>17073564then what is local realist in consistent histories
>>17073569It’s what I said: that the outcomes of the measurements you make on entangled particles are guaranteed to be (anti-)correlated because the wave function encodes that from the moment of the particles’ pair production (which is local)I am happy to answer GOOD questions or discuss things at a level where it seems like you are actually reading and responding, but right now this is rather tiresome because I am just repeating things you could just scroll up and read without me doing these repetitions. I also asked you to read a short excerpt from book that you can easily find and apparently you have not
>>17073572but guaranteeing they are anti-correlated means that one particle needs information about the other particle's outcome. this is non-trivial because you can freely choose the measurement setting and you can make the choice even just a moment before the measurmeent is made, well after the particles are created and when they are many miles apart. yeah you can say something like "quantum variables are just different" but its obviously non-local
>>17073567A wavefunction is not “local” nor “nonlocal”. A wavefunction is a description of a physical system that exists on paper; it doesn’t physically exist within space and time. To even ascribe the concept of “local” or “ nonlocal” to a wavefunction is the wrong thing to do. The particles and measurements made on them, and any potential signals propagating between them is what needs to follow the rules of locality. Not wavefunctions.to make it brutally obvious, you realize that wave functions (or state vectors) live in something called Hilbert space (or its multiparticle generalization, a Fock space), right? And you realize Hilbert and Fock spaces have many many more dimensions than just 3+time, right ?
>>17073573no, this is the crux of the matter. I claim that they are quantum variables, which are different from classical variables, but nevertheless it is not at all nonlocal. Nothing in the entire chain of my explanation ever resorts to non-locality. You are the one conjuring that up because you are trying to impose some classical concepts where they don’t apply
>>17073578It is pretty unnerving how many people fail to get a premise this trivial, measurement is not what gives it value. There is not a magical point of appearance when we finally get around to measuring it, the universe already knows and we had to blind ourselves/the instruments for the quantum values to keep from decohering. We are "loud" up here in the chemical realm, keeping our noise low /makes/ measure possible, it doesn't rewrite physics for us to choose an experiment.
>>17073596I think you basically have it right. Kind of a poetic way of expressing it but I think you and I are on the same page
>>17073578>dictatorial handwave>with the deBroglie/Bohm formalism all this gets resolved>mein Bell... Bohm... Bohmians couldn't muster enough brains to make the theory relativistic. Bohm's revolution did not succeed>ES WAR EIN BEFEHL!!!
>>17073661ah shit I missed a line there>*drops glasses on table with a trembling hand*>there will remain in the room only Klauser, Aspect, Zeilinger... and Aharonov
>>17073661>>17073667Honestly I don’t get your point. I have the utmost respect for Aspect and Kalusonger/Zeilinger. In fact I think if you look through the archives of this board (as I have instructions about earlier in this thread) I was saying that Aspect should be getting the Nobel years before he actually got it . So with that in mind, what are you trying to say?
>>17073678that qm is in a state of zugzwang which you seem to not recognize, yourselfBell proved theoretically and Aspect et all by experiment that there is no way to maintain the illusion of local realism and more importantly that HIDDEN VARIABLE THEORIES CAN'T EXPLAIN QM OBSERVABLESyou keep handwaving hitleriannily about how quantum variables are just built different, but that's just copium
>>17073681It’s not me, it’s Murray Gell-Mann. I am not trying to appeal to authority since I have been trying to defend this perspective on my own with logic and facts for hours, even days now. But my argument is basicallyjust trying to reiterate what Murray Gell-Mann said. he expressed it in his own word in the book i mentioned several times here. I plan to continue arguing with you shills but i’m putting my cards in the table, unlike you fuckers (i assume you are all retired boomers. that gives you an advantage on the time you can devote to this shit since you are all retired boomers, but at the same time you are all so hopelessly lost and out of touch that it makes me pity you)
>>17073693I don't think we disagree in the way you believe we disagree>>17072931>You don’t need nonlocality nor non-“realism” to explain Bell’s theorem experiments.yes you do. you need to abandon locality, realism or the arrow of time>Gell-Mannone of the boldest scientific fraudsters of the 20th century, introduced renormalization because QED kept blowing up on uncensored infinities (it still does), made up quarks because QCD didn't work (still doesn't work, new "colors" of ever smaller particles keep being added, it's epicycles all the way down), was great friends with Jeffrey Epstein>>17073564>Quantum variables are just different.>>17073578>I claim that they are quantum variables, which are different from classical variablesdifferent how?
>>17073518>But the way you get perfect (anti-)correlation across space like separated distances when both particles spins are measured along the same axis arises from the fact that they were (anti-)correlated from when they were produced.Bell proved that local hidden variable theories can be constructed for a few special cases like this one but he also proved that they can't exist for arbitrary detector orientations.>You can find it screenshotted in the archive of this board on warosu.org.

>>17073702renormalization group, sorryrenormalization was introduced by Feynman who at least had the decency to observe that it was a mathematically dubious, physically meaningless kludge and a new theory will be needed to do away with it...which Gell-Mann and friends took as license to instead EXTEND the theory they knew was no good and introduce an infinite tower of kludges to hide the inevitable fuckups under the rug
>>17073765btw, any interested anons should read the wiki talk page, it's high comedyhttps://en.wikipedia.org/wiki/Talk:Renormalization_group>I have a question. The article speaks about the "renormalization group", but nowhere does the article prove that there is a structure that forms a group.

>>17073702>QCD didn't work (still doesn't work, new "colors" of ever smaller particles keep being added, it's epicycles all the way down)are you seriously this retarded? The Standard Model of particle physics was basically formulated in the 70s by Wilczek and Politzer (Gross took credit for Wilczek’s work, and ‘t Hooft had the answer before any of them but that is another story). The theory was complete over 50 years ango. And by 2000 the top quark was observed and in 2012 the Higgs was discovered. The standard model has basically been completely settled and it makes extremely accurate predictions. The current crisis in particle physics is exactly the opposite: nothing new at all has been added to the standard model for decades, and all proposals (GUT particles, supersymmetry, dark matter particles) have failed to materialize, leaving the standard model untouched for decades. I don’t know what kind of insanity you have but it is causing you some serious delusions
>>17073576I mean the whole thing that kickstarted the locality debate was a debate about the wavefunction where Einstein was concerned that the wavefunction requires nonlocality if it collapse. so the ontology and interpretation is relevant.
>>17073578theres no point in saying there are quantum variables different to classical variables if you cant specify what that even means. i have just given a valid question in response to the account you gave and you can't even comment on how my concern would be alleviated. if you are going to say that we have some new quantum variable different to classical notions of non-locality, then you have to explain why
>>17073957>it makes extremely accurate predictionsit's a curve-fitting exercise lol, fuck knows what's actually going on, physicsniggers certainly don't seem to care>muh fine structure "constant">muh renormalization "group"fuck off

>>17074133it’s different because as I said, a state like [(up1+down2)+(down1+up2)]/[sqrt(2)] does not mean that particle 1 and particle 2 are both half-and-half up or down and until particle 1 is measured and some knowledge of the result of the measurement gets to particle 2 somehow (locally or nonlocally) then it doesn’t know how to anti-correlate with particle 1 (this is what a native classical interpretation would say). instead the state encodes the anti-correlation the instant those particles exist in that state, i.e when they are produced at the same spot. So it is local.Did you read the book passage in the warosu link I posted yet ? Or am I speaking to someone with Zoomer brain who refuses to read six pages and instead needs to be spoonfed waters-down explanations of the source material?
>>17074149>>17074153>>17074157Wow, someone is seriously triggered!

I realize that some people have emotional connections to some “alt-science” stuff (maybe because of religious convictions that don’t jive well with the consensus understanding of the scientific community) but even still, some decorum is warranted instead of chomping out and throwing f-bombs repeatedly

>>17073569Consistent histories manages to be local by sacrificing realism.>The cost of this strategy is that the formalism permits multiple incompatible but equally valid frameworks, so no unique, framework-independent account of past quantum events is selected.
>>17069476All the quantum weirdness comes from one assumption:You can choose to carry out a certain measurement causally independent from the rest of the universe which in turn forces the universe to non-locally respond to your decision.Of course that's bullshit.
>>17073944>branching histories>>*slaps hood* haha this baby can fit so many universes in itwhere does the energy to create all these branches ex nihilo gajillions of times per second come from?
>>17074351I already said that I admit that Consistent Histories brings the definition of “realism” into the spotlight. I actually said this *repeatedly*. But there is still some concept of “realism” in Consisten Histories, it is just not a straightforward thing if you are thinking in terms of classical intuitionanyhow thanks for pointing this out. Consistent Histories is very stringent on canonical locality but where it causes confusion is in terms of how we think about “realism”
>>17074360>the photons telepathically tell Alice which way to orient her polarization filter this timeayy lmao
>>17074363No, it's just physically impossible to orient the filter any other way
>>17074361where does the Path Integral get the privilege of doing a superposition of infinitely many different particle trajectories from? Let me guess, you don’t like path integrals either?
>>17074365mine's a mathematical object, yours an allegedly real physical process which is allegedly required to explain some observable physical phenomena and to do so by allegedly creating vast amounts of mass energy out of nothingand let me try to help you out of your Everettian delusion in yet another way: these universes need to contain all possible outcomes for all observers, so does one need to get created for every observer that gets Lorentz boosted anywhere?
>>17074364>justpropose another mechanism by which the spin of the photon and the orientation of the filter are causally bound
>>17074370Everything is causally bound
>>17074368I think now you are falling into the trap where Consistent Histories sort of diverged into different schools. If you look on Wikipedia’s entry about Consistent Histories, the misguided wikipedians make the conclusion that Consistent Histories is basically an improved Copenhagen interpretation. Those folks pushed it in the direction completely opposite anything “Everettian”. It’s not Copenhagen and neither is it Many-Worlds. It is a way to reconcile quantum variables with the fact that there is just one history of the universe subject to the fact that quantum variables have some randomness in them.Gell-Mann uses the “branches of history” vocabulary but one does not need to think of those branches as physically real (or even more stupidly, requiring some supply of energy to produce them). Consistent Histories, in a proper form (not the Wikipedia form nor the bastardized Many Worlds read on it you seem to have stumbled on) just has some quantum variables which take randomized outcomes, but they follow from one single timeline through history (one real branch, the other “branches” Gell-Mann refers to are things that could have, but did not happen). it is not a deterministic interpretation
>>17074372not enough, niggernot enoughyou see, the filter has to be rotated JUST SO, and EVERY GOD DAMN TIME, not just once or twiceyou need a mechanism for that, some sort of evolution rule for the universe that makes that particular sequence of events happen, not just some bs handwavy "it's all determined from the Big Bang", I mean, okay it's determined, but why is it determined to happen this particular way? why do events exhibit this regular pattern? you're not off the hook, your nigger ass still has to do some physics, ya feel me?
>>17074375>why do events exhibit this regular pattern?That's just how the universe works. I could ask that about anything. Why do the constants have the values that they have? Why does space have 3 dimensions? Etc. ...
>>17074377yeah, that's called doing physics, discovering the rules of the game. if you're not interested in discovering the rules of the game, you just a basic bitch nigga
>>17074374>there is just one history of the universeand which would this preferred foliation be? and what do you propose to use instead of GR and SR which you've just thrown out the window?and for the second time, what do you mean by "quantum variables" and how do you believe they differ from regular-ass variables?
>>17074383> and which would this preferred foliation be? there is no preferred anything. The random outcomes of measurements of systems like (up+down)/root(2) are just what they are, we accept that and move on.>and what do you propose to use instead of GR and SR which you've just thrown out the window?I absolutely never said anything like that. SR and GR are valid>and for the second time, what do you mean by "quantum variables" and how do you believe they differ from regular-ass variables?i have explained this several times already. I would appreciate big you could refer to specific points in the discussion above where I already had this conversation
>>17074389there has to be, because various observers see events occurring in different orders, and the only way you could assemble those into One Coherent History is to claim there is One Preferred Frame where it all makes sense and you can Lorentz transform all the observed sequences of events into that frame and they would all coincide>i have explained this several times already.nope
>>17074285but the correlations that come out of the state are all in different bases that depend on the setting of the measurement device. it cant all be encoded at source because the correlation depends on the measurement device which you only know about later. so your logic is wrong. yeh sure if we were only talking about anti-correlations of two devices with the same setting you could determine at source. but you can make the devices different directions to eachother freely and in order to get the correct quantum correlationa each particle needs to know both measurement device settings. it cant be decided just at source
>>17074394You are making a linguistic error. The Consistent Histories interpretation doesn’t insist that there is a preferred reference frame for ordering events that are spacelike separated. Maybe you intuited that from the vocabulary of the name? But Consistent Histories does not make any claims to that sort of nonrelativistic ordering>>17074817but it can be determined at the source if you don’t insist on some inappropriate classical interpretation. The choice of measurement device or orientation of spin measurements does not affect the state. The state encodes the correlations at the source. Whether you choose to do one measurement or another is fine for the state; the state you perform the measurement on doesn’t care what measurement you do on it (it only decorrelates as a result of the measurement process, i.e. it changes when you measure the particles described by the initial state, but the incoming state on which you perform the measurement doesn’t react to what measurement you are doing to it). So the correlations; no matter whether you are doing the measurement that implies perfect anticorrelation or whether it’s a measurement where there is no correlation, is all handled in the state that gets encoded at the instant of pair production
