What research have you done on this? What have you found so far?OCD said:TL;DR Summary: what is the consensus about the information paradox?
from what I understand it is believed that information is preserved but we are still working out how exactly, is this the case?
no I haven't read "The Black Hole Wars" I know that it covers the dispute between Susskind and hawking and that Hawking eventually concedes to a information preservation resolution. from what I understand Susskind's answer to the paradox is the holographic principle. Most of the recent literature that I have found about this topic conclude that information is in fact not lost which is why I asked the question.phinds said:What research have you done on this?

Thanks. Both of these papers illustrate a common problem with theoretical approaches to this issue (as well as many other issues). The framework they are working in is an asymptotically Anti-de Sitter (AdS) spacetime. This is commonly done in string theory and related fields because it is mathematically tractable. Unfortunately it is also physically irrelevant, because our universe is not asymptotically Anti-de Sitter, it is asymptotically de Sitter. So a physically relevant model would have to use something like Schwarzschild-de Sitter spacetime, i.e., a black hole in a de Sitter background.OCD said:
The Black Hole Information Paradox arises from the conflict between quantum mechanics and general relativity. According to quantum mechanics, information about a physical system should never be lost. However, when matter falls into a black hole, general relativity suggests that the information could be lost forever once the black hole evaporates via Hawking radiation. This paradox challenges our understanding of fundamental physics.
Yes, numerous proposals have been put forward to resolve the paradox. Some of the most notable include the idea of black hole complementarity, the firewall hypothesis, and the holographic principle. Each of these approaches attempts to reconcile the loss of information with the principles of quantum mechanics, but a definitive resolution has yet to be universally accepted.
The holographic principle suggests that all the information contained within a volume of space can be represented as a theory on the boundary of that space. In the context of black holes, this means that the information about the matter falling into a black hole could be encoded on its event horizon, potentially preserving the information and offering a way to resolve the paradox.
The current consensus is that while substantial progress has been made, the Black Hole Information Paradox is not yet fully resolved. Theoretical advancements, particularly in the context of string theory and quantum gravity, have provided promising avenues, but a complete and universally accepted solution remains elusive. Many physicists believe that a deeper understanding of quantum gravity is necessary to fully resolve the paradox.
If the Black Hole Information Paradox is resolved, it would have profound implications for our understanding of the universe. It would likely lead to a more unified theory that reconciles quantum mechanics and general relativity, potentially offering new insights into the nature of space, time, and information. It could also influence our understanding of black holes, the fundamental structure of the universe, and the ultimate fate of information in cosmological processes.
