The Nobel prize in physics is typically awarded to scientists who make sense of nature; those whose discoveries render the universe more comprehensible. But the 2022 Nobel has been awarded to three physicists who revealed that the universe is even stranger than we thought thanks to Quantum Entanglement

I love this channel for ideas and theory, and I also love Anton Petrov's channel for latest news about various discoveries and mysteries of Astrophysics. Here's a take you might like, by the well-known Sean Carroll. From his perspective, literally anything that can happen, the slight deviation in movement, spin, path, or whatever, of a single quark, all the way to the largest, incomprehensible cosmological events all does happen at once, sort of like the Multiverse interpretations. Yet what we see at macro scale Reality, is only where these things overlap the most, with the rest disappearing into oh no I can't remember and I've gone cross-eyed.

@Jaime_Protein_Cannister 11 місяців тому
@Kassius KLAY there is no consciousness involved, you're just repeating sensational Google bs people read. A particle exist as a superposition of states and has no deleyed will or hidden variables. The point being once information about an object is taken such as speed,spin position , etc ,the variable can no longer change, yet up until that moment the object has not collapsed. This can be caused by objects without conciousness once so ever. It's like a turtle hiding into its shell after being affected by external stimuli, an observation in scientific terms means "collection of information" as opposed to "eyeing it" The misunderstanding about it generaly comes from eraser experiment. People don't understand the mechanic and read made up headline which is no different to celebrity gossip site

Thank you for pointing out that Bell's Inequality and the experiments honored by the Nobel Prize only rule out local hidden variables theories. I'm not saying I'm necessarily advocating for pilot waves or any other non-local theory, but it's been annoying seeing videos discussing this topic completely ignore that they may be disproving locality rather than hidden variables.
@davidhand9721 Рік тому
Until I saw Sabine's video on the topic, I spent a few sleepless nights worrying about fundamental randomness & non-realism, having only seen glowing headlines. I already knew that these experiments had been done, but I didn't realize they were only now getting the Nobel recognition. So when everything I see just says that the Nobel prize was given out for proving reality isn't real, I get very worried. Luckily Matt and Sabine are here to talk us down. I'm sure it's in this video somewhere, too, but pilot waves are far from the only escape hatch here. Many Worlds never collapses a wavefunction, so all results still exist and the results don't have to square until they're brought together, at or below the speed of light. It's really very elegant when you look at it as just math and forget about everyone telling you there are branching realities. "Superdeterminism" is the more popular option, though, I believe, and it really isn't different from just taking determinism seriously. With either of those interpretations, you get to keep locality by thinking about realism a little differently.

I've always wondered if quantum physics issues arise because we're 3d creatures trying to understand multidimensional objects. What if entangled particles share a higher dimensional coordinate. Like how polynomial equations can have two answers, entangled particles intersect our 3d reality at multiple locations. So information isn't traveling "faster than the speed of light" but instead it's basically just one system connecting the two points in 3d space. This could also explain the weird shape of atomic orbitals and stuff in chemistry too. Those might be "perfect shapes" in higher dimensions.
@falnica Рік тому
That extra dimensional coordinate would be a hidden variable, and given the results of these experiments, that coordinate would need to be independent of everything else happening in spacetime, if it even exists. For more about this, look up "Superdeterminism"
@zataritamods7499 Рік тому
@@falnica I agree, except the way I see it is the particles are the result of the system, not the system it's self. Like the x intercepts in a polynomial. What we see is only a part of the system. Our reality is the x axis in that analogy. So the particles might not have the extra variable, the system that exists in higher dimensions have the variables. The particles just intersect our 3d reality at those points. And us being 3d entities are trying to reverse engineer the system from our limited perspective. I dunno to be honest, that's just sorta how I've always imagined it working in my head, and "dark matter" is just these systems that dont intersect our 3d reality; however, it influences the rest of the systems that do intersect our reality

For entanglement to happen, as observed, the particles have to be placed near each other. They cannot be entangled if one of the particles exits far apart, like 100,000,000 miles, for example. Therefore, an ACTION has to take place to get them entangled. If all it takes is an ACTION, like motion, then there must exist in nature entangled particles. Has anyone discovered an naturally occurring entangled particle?

Well done Matt on your fluent descriptions. I have one question regarding Quantum entanglement and the principle of instantaneous action at a distance. Assuming the two entangled particles measured by Alice and Bob, are each taken in their spaceships going in opposite directions at speeds that create some measurable time dilation; when the instantaneous action happens, do Bob and Alice see the effect happen at the same time, or is the ‘instant’ measured as being at the relative times of each? If the latter is true, on one objective perspective, the action takes place at a future time relative to the other and creates an interesting dilemma. If the former is true (ie at a time agreed by the observer to be the same (not sure how), then Alice and Bob measure the ‘instantaneous action’ as taking place at different times.

The thing that really convinced me and frankly it was shocking and very disturbing was the first experiments with single Photon and single electron two slit diffraction. To this day I'm unclear why a careful examination of that seminal experiment isn't as clear an illustration of non-locality/ in determinism.

Take a peek at either particle and automatically know the state of the other because the entanglement, by definition, makes this so. So the options are a or b. The two particles are jumping between AB & BA. You finally take a peek some time after and the particle you have locks in to A Or B And now you know the other psrticle.
