Quantum electrodynamics predicts that even in an evacuated room there might be spontaneous pair production, electron, positron. They would immediately annihilate, the gamma ray so produced would propagate and initiate another pair production.
Thank you for posting this. While watching, I pondered the question "Aren't all particles in the universe entangled since they were close together before the big bang?"
Yes but you can have degrees of entanglement (multi partite). What Prof Susskind is talking about is maximally entangled particles (Bell Pairs). But yes interesting point to think about space is all connected in some ways. Quantum gravity will be cracked in the next 10years no doubt from this idea. How else could space be structured. Glad Einstein cracked it without him even knowing it, he laid the clues.
The same way twin brothers are entangled and look alike or act in similar ways. Is there a spooky at a distance between two twin brothers when they act the same way in distant locations? No. Is quantum entanglement really entanglement or can this be explained by hidden local variables (like DNA in the case of the twin brothers)?
It seems reasonable that particles are entangled since the Big Bang would require unless the density was so great that this position would require loss of spin and perhaps leave everything as a wave vs a particle.
@4:00 this is highly misleading. It is only on the D-1 dimensional holographic boundary CFT that "space" is "held together" by entanglement --- that is a consequence of dropping down one dimension. In the D-dimensional gravity bulk it is all ordinary spacetime of general relativity or string theory, which is a continuum manifold at least down to the Planck scale, so it is not "held together" by any "glue". In the gravity bulk, spacetime itself is the glue, and entanglement is wormhole bridges. It's only if you think the boundary dual is in some sense more fundamental that you need to think of entanglement as a glue.... and you don't... you don't need to think of the boundary CFT as more fundamental. In any case, gauge/gravity duality is only precise for AdS spacetimes, so it's not _our_ universe you need the glue for. Here's an (imperfect) analogy: if I paint the end tips of the spines of a porcupine photo-luminescent and turn off the visible RGB lighting I see weird entanglement between spines which seem to glue my porcupine theory together. I can choose to fool myself into thinking the spine ends are the only real physics, and then I'd say the spine entanglement is my spacetime glue.
The bridge is equivalent to a quantum jump. (Leaving out all the modulation-connection details as requested) _____ QM-TIME connection analysis, if the 1-0D superposition-symmetry by infinite-eternal reflection is the quantum-potential operator, is a structured "chord" of Quantum Fields that form the particular arrangement of spacetime-entertainments.., that also correspond to the "One Electron",(=unitary-universe) theory. The above example demonstrates a specific relationship, but the circles would correspond to the superimposed quantum bubbles of spinfoam, pseudo random connection. (Repetition of a concept in as many formats as are relevant to the evidence as possible, is the perceived technique for learning empirically and intuitively)
He didn't offer any proof or evidence about, for example, 3:15 that empty space is entangled or that rupturing the entanglement would separate this emptiness, but if Leonard Susskind says it, by reason of authority, I agree.
Many Worlds hypothesis tries to explain this. I’m just a hobbyist but the word I tend to hear is that systems branch or evolve through “time”, similar to a fractal tree? leaving 10^144 (I believe the term “shitload” is acceptable) “copies” behind every second. Of course we can’t test this yet, and I have no more credibility than anyone else. PBS Spacetime has a good unbiased video that goes more in depth without melting your head with math. Sean Carrol is ok to listen to about it, but he seems more biased in his approach.
Space as we perceive it is the duality and emerges from entanglement. You are a quantum lense projecting that space because it makes it easier to find food and masturbate. Just clean up your gluons when you’re done.
