What is the Information Loss Paradox and How Does Hawking Radiation Relate?

Click For Summary
The Information Loss Paradox arises from the conflict between general relativity (GR) and quantum mechanics (QM) regarding the fate of information that falls into a black hole. GR suggests that information is lost forever when it crosses the event horizon, while QM posits that information must be preserved, allowing for the reconstruction of initial states. Hawking radiation, a process through which black holes can evaporate, raises questions about whether the emitted radiation contains the information of the matter that fell in. Various theories propose that correlations in Hawking radiation could encode this information, but there is no consensus on how this occurs. The discussion highlights the complexities of reconciling GR and QM, emphasizing that the nature of black holes and information remains a significant area of debate in theoretical physics.

But that is why different philosophies are directly relevant to science.
Where else do new concepts about the fundamental nature of reality come from but from differing views or “scientific religions”
New concepts come from the same place they always have-- unexpected experiments or observations, not philosophies.
It is not the job of referees to decide if the philosophic belief that might be contained within an idea; it is actually a problem that they often do reject scientific doctrine not in line with their own even if the ideas in the papaer may be workable.
The role of the referee is to evaluate the axioms chosen, not from the perspective you discussed of what is "right" or "wrong", but rather what is or is not appropriate to the goals of the investigation. That's the point, "doctrine" and "philosophy" should play no role at all. That may not always happen in practice, but I brought it up because you said that you can evaluate what is "right" without first tailoring the very meaning of that word to the given situation.
And papers shouldn’t be considered Right or even Accurate because they are published, only useful.
I agree-- which is exactly why you do have to first consider how the word "wrong" gets used before you can be a referee. You said that your interest was only in what is more accurate, and that's fine for you, but it means you cannot be a referee. I was establishing the importance in not applying black and white meanings of right and wrong to theories, especially when based on a philosophical rather than a practical stance.
For example there are several models proposed for an atom (cubic, plum-pudding, Saturnian, Rutherford, Bohr) using any of those is not a disqualification for a paper; Only that the ideas and how they are used may actually be useful in the context of the paper.
That is the point I am making. Contrast that to "the search for the right philosophy".

For example, Bohr circular orbits in the Bohr Atom is well understood to be wrong and an incorrect description of atomic structure. But even modern papers still use Bohr circular orbits as an analogy of reality that accurately helps describe fundamental elements of nature such as the fine structure constant. ]

I don’t think the current scientific consensus that these atomic models are ‘wrong’ yet some remain useful as scientific analogies of reality, will ever change to declare one of them as a correct and complete description of atomic structure.
Again, you are only repeating my point. You said that you personally were "more interested in figuring out what is wrong, to get to a more correct solution".
In the same way I believe QM will always serve as an accurate analogy of reality but someday we will be able to demonstrate that QM and Bohr as wrong to consider it a complete description of reality.
I'm there already. I take it as the default position of science that our search is for accurate analogies of reality, not "a complete description". When did we start thinking we were doing something else? Or I suppose the better question is, when should we have stopped thinking that?
But it does not explain what HUP is, it only gives an analogy of it.
We never explain what anything is. Do we explain what gravity is? Or time? We have no idea what these things are, but we build models for how they work or ways to measure their results. That's why we will never have a "complete description", the best we can do is unify what we have found to work. Even that seems unlikely to me, but the effort is noble as long as we don't mistake it for something it isn't.
But an incorrect analogy of nature because it is incomplete;
If that were true, then no analogy of nature could possibly be correct, because as we agreed, no analogy of nature is complete. An analogy need not be complete to be correct-- that would be an identity, and would not even serve the purpose of an analogy.

Individual particles of water and items of fluff floating on the water are rearranged as dispersion has moved them to new locations.
I didn't say the information in the particles was reversible (they are a complex system, which is from whence I claimed all irreversibility originates), I said the information in the wave was reversible-- the latter being the analog of the HUP.
This like many other examples support HUP & the one way direction of thermodynamic entropy, and tells me that “information conservation” should not be considered a requirement of reality.
But the mechanism you cite, the action of the particles, has nothing to do with the HUP-- that action was happily considered irreversible long before quantum mechanics, that's my point. It is not something fundamental that makes it irreversible, it is how we choose to treat the system, out of practical considerations. Again, it is not "what is right", it is "what axioms we choose and why".

And IMO HUP defines QM as not requiring information conservation.
Refuting that is why I mentioned the information reversibility in a wave that is governed by the classical analog to the HUP.

To the extent that some issue refereed papers stating otherwise; I’ve not seen any give satisfactory detail on how information is conserved from the past anywhere in nature, without nature propagating a Super-deterministic future.
It is not the universe that is either reversible or super-deterministic, it is our chosen axioms that either are or are not. The axioms of quantum mechanics are reversible and deterministic, but not super-deterministic because they are unpredictable in how they will couple to the complex classical systems that make measurements.

what if hawking radiation is not proved..i think it is not yet proved...will this give any answer for this paradox
