It goes back to the French revolution where the people who sat on the left of the parliament opposed the ruling class, in that case the feudal aristocracy, while the people who supported the ruling class sat on the right of the parliament. Even after the aristocracy was gone, people started to use the term left to refer to people who oppose the ruling class of capitalist society (wealthy capital oligarchs) where as the right is those who support them.

“this isn’t right vs left, this is right vs left”

uh… okay?

I still don’t really understand why the information just can’t be destroyed. It seems like we’re starting from an assumption that it shouldn’t be destroyed despite it being so in semi-classical gravity, and then trying to think of alternative theories which could preserve it such as on the boundary or in its charge/mass/spin. Maybe that’s correct but it seems like speculation, and it’s not speculation based on any actual contradiction between theory and practice, i.e. not because semi-classical gravity has actually made an incorrect prediction in an experiment we can go out and verify, but only because we have certain preconceptions as to how nature should work which aren’t compatible with it. So it doesn’t really come across to me as a scientific “problem” but more of a metaphysical one.

There’s still a pattern in the results, so by one means or another we want to explain the results. Just calling it nondeterministic, if I understand right, would be just saying you can’t predict it from prior observations. So, whatever language you use to describe this puzzling situation, the puzzling situation thus far remains.

I mean nondeterministic in a more fundamental sense, that it is just genuinely random and there is no possibility of predicting the outcome because nothing in nature actually pre-determines the outcome.

A priori?

Through rigorous experimental observation, it’s probably the most well-tested finding in all of science of all time.

Or because it best fits with Relativity? It sounds about as strong as saying, “we know time is universal.” It’s obvious, has to be true, but apparently not how the universe functions.

So we can never believe anything? We might as well deny the earth is round because people once thought time is absolute now we know it’s relative, so we might as well not believe in anything at all! Completely and utterly absurd. You sound just like the creationists who try to undermine belief in scientific findings because “science is always changing,” as if that’s a bad thing or a reason to doubt it.

We should believe what the evidence shows us. We changed our mind about the nature of time because we discovered new evidence showing the previous intuition was wrong, not because some random dude on lemmy dot com decided their personal guesses are better than what the scientific evidence overwhelmingly demonstrates.

If you think it’s wrong show evidence that it is wrong. Don’t hit me with this sophistry BS and insult my intelligence. I do not appreciate it.

Maybe you are right that special relativity is wrong, but show me an experiment where Lorentz invariance is violated. Then I will take you seriously. Otherwise, I will not.

It could do that but what’s the evidence that it does? Or has someone proved this is already a feature of semi-classical gravity that just wasn’t noticed before? Or is it only a feature of a brand new hypothetical theory?

why’s it a problem? why can’t information just be lost at a black hole?

No they haven’t.

Quantum nonlocality really is a misnomer. Nothing is nonlocal about it. We know from the No-communication Theorem that there is no physical interaction you could carry out with one particle in an entangled pair that would affect the state of the other particle, and we know it is compatible with special relativity, which is a fundamentally local theory, as such a unification of the two is how we get quantum field theory.

“Local realism” is also a nonsensical term. There is no agreed upon rigorous definition of “realism” and its introduction to the scientific literature has only served to confuse the discussion and promote quantum mysticism because people think because Bell’s theorem supposedly shows that “local realism” is false that you there have to choose between locality or realism, but not both, and since we know the universe is local, we have to conclude there is no objective reality, devolving into mysticism and idealism.

This isn’t just a problem in popsci articles but even in published scientific literature. This “local realism” hogwash has caused even otherwise respectable physics to publish nonsense about how reality doesn’t exist. The term “realism” is never used in Bell’s theorem and has tn relevance to it. Bell’s theorem is about local hidden variable theories, and it is complete nonsense to conflate hidden variables with “realism” as if your only choices are to believe the reality is deterministic or to deny reality even exists! What kind of options are those? What about a third option that reality exists and it is just nondeterministic?

What Bell’s theorem shows is that quantum mechanics cannot be replaced with a local hidden variable theory, and since we know the universe is local, that means it cannot be replaced with a hidden variable theory. It forces us to accept nondeterminism, it doesn’t force us to deny reality, nor does it prove there is nonlocality.

It can, under certain conditions, contain information about things at a distance, but a function is not a physical entity and its reduction is not a physical process, so none of this reflects anything superluminal actually going on in physical reality.
