In AdS/CFT correspondence, higher-dimensional space and gravity are not the source of quantum mechanics, they are emergent illusions generated by quantum entanglement on the lower-dimensional boundary.
Quantum non-locality is just what a higher-dimensional geometric connection looks like from the boundary. To us it looks non-local. At higher dimension, it’s local.
I happen to like this theory and would love to see a video on this.
@AzVidsPro Says:
what if instead of using the state of the spin(at collapse) to try to transmit the message(which is obviously impossible hence this video), we do something with the ones that have already been observed/collapsed? I mean to say that we should rely on something else other than the state.I'm coming from the standpoint that if you can deduce that something unknown is the same value in 2 different places and do it instantaneously regardless of the distance between them, It's kinda useless.
@thinkforyourself2109 Says:
"While certain quantum effects—such as entanglement and tunnelling—show correlations or transit times that look faster than light, they do not violate Einstein's speed limit because no usable information or physical signal is ever transmitted. In quantum entanglement, the physical states of two particles (through spin or polarization) are linked. If you measure the state of the first particle, its entangled partner instantly assumes a correlated state, even if it is light-years away.
"But this isn't faster-than-light communication because the outcome of a quantum measurement is inherently random (a 50/50 chance for states like zero or one), and because you cannot control what result you will get when you measure your particle, so you cannot use it to encode, send, or trigger a predetermined message to someone else. The person on the other end only knows what their particle's state is after they measure it themselves or receive a normal, sub-light-speed message from you.
"The Hartman Effect is when subatomic particles can occasionally pass through a physical barrier that classical physics says they shouldn't have enough energy to cross. Calculations in experiments (like the Hartman effect) suggest the time a particle spends inside the barrier can be extremely short—so short that it mimics speeds greater than light. However, standard physics shows that you cannot use quantum tunnelling to send a recognizable, faster-than-light signal or transfer actual data through the barrier faster than a photon travels in a vacuum."

No one has a problem with space itself expanding faster than light after the big bang, so why is faster than light information transmission between entangled particles a problem either?

All probabilities that do not appear collapse and are erased from the universe. If all possibilities would appear, the result would be chaos in the universe and paradoxes.

Is the spin much faster than the speed of light? Therefore does it slow time?

The “Many Worlds” theory is just a way that scientists lacking common sense use to explain puzzles they can’t solve yet!
@jeffroberts6865 Says:
All joking aside, one thing still puzzles me is how experimenters know that the two particles they produce are actually entangled. Perhaps these days it's an assumption based on earlier work, but nevertheless I still don't get it. It seems to require a priori knowledge. One answer I have been given is that while explanations of these kind of experiments talk about producing two entangled particles from some source, in reality the sources produce many pairs of particles, some of which won't be entangled, and the experimenters test them all to build-up a statistical view of entanglement. The testing is done not only using Bell's theorem but apparently quantum tomography (a subject for another day, perhaps).

@syedazadar914 Says:
We measure the speed of light in labs and assume it's the same everywhere. But the Michelson-Morley experiment was designed to detect motion through a stationary ether — not anisotropy in a moving superfluid. Recent DESI data and GRB polarization studies both show directional dependence at cosmic scales. The speed of light might be constant locally but not globally — and we've been measuring it wrong for a century. @DRUMSUnifiedTheory has the lab test proposals.
@darkstatehk Says:
I've started to feel uncomfortable with the term "Speed of Light" because if gravity travels at the same speed, then obviously they are obeying the same law. Magnetism travels at the speed of light, so it's electromagnetism that's traveling at the same speed. We should start calling it Invariant Speed of Spacetime, or the Speed of Causality.
Anchoring it to one aspect, i.e. light., doesn't give a full understanding.

@SirDipsauce Says:
@veritasium the particles are keeping spin, meaning the measured spin is rotating counter to the entangled particle, unless another force acts upon one of the particle to alter the spin of the spin. The local variable is essentially a nesting sin function, since it is a round object, like how the analog computer calculated tides with pulleys

It's interesting to me how many people say the word "like" as a filler for their brain to formulate the next thought. (Some people use other words haha) I remember when this became popular back in the 80's i believe. It's pretty much permeated throughout English speaking society without anyone giving a second glance to it. I wonder if a Veritasium video dedicated to that might be, like, in order. Oh, and superposition and quantum entangled spins are pretty cool too :)

@davidwilliams7094 Says:
This experiment proves nothing. It is only a more complex version of Einstein's original thought experiment. This "experiment" is so infuriating. Every video on this topic does the same thing. They give a simple reasonable explanation of what quantum mechanics predicts, but then they give an absurd convoluted explanation for what a local theory "should" predict. The local particles do not plan ahead on how they will be measured, they simply exist as perfect spinning opposites of each other in some random orientation. In the quantum explanation the measuring of one particle causes the probability field to collapse into a state in which the pear of particles are perfectly opposite of each other, which is physically indistinguishable from the local theory. If rotating the measurement devices by 60 degrees will cause the perfectly opposite quantum particles to disagree 25% of the time then a perfectly opposite local particles will also disagree 25% of the time. The only reason this "experiment" predicts a different percentage for local theory is because it is forced into this 6 state binary description that strips away the error rate created by the 60 degree twist. If you switched the descriptions that you used to calculate the percentages then you would find the local theory giving the correct percentage and the quantum theory giving the wrong percentage. And there is no reason that the descriptions couldn't be switched.
@GilbertGauger-p9j8v Says:
I studied physics in the seventies and these issues were presented. At that time my instructors being mostly veterans of the Manhattan Project, there was a very strong bias towards Copenhagen. Bell’s work was presented and the nature of the conflict was really only acknowledged and not explained well. Thank you for this presentation which much more deeply and clearly addressed the topic. I have the greatest respect for your work.

@shaungold Says:
The issue of Quantum Entanglement is very easily resolved. No matter how far away Entangled particles become, they are always still local regarding their spin. There is no sudden interchange of information at a distance. The measured particle has always been what we measure. So the other entangled particle is also already the opposite.
Bell's theorem didn't discover a paradox in nature; it simply exposed the limitations of traditional, fragmented mathematics.
