The only indication that I got was that someone considered this not to be mainstream physics. They don't explain why or what I could edit to improve my post. Furthermore, this is a legitimate physics question because I have been working on it with a physicist in real life. In any case, I am now banned from making new posts, despite the fact that I only have 2 posts (now 1). So, this kind of moderation is effectively a trial, judgement, and execution with no possibility for appeal, improvement, or education. I don't understand how this approach edifies anyone whatsoever. What kind of community just murders people on sight without warning or explanation?
This is the message that I get when I try to ask a new question: Sorry, we are no longer accepting questions from your account...Please do not create a new account. Instead, work on improving your existing questions by editing them to comply with the site's guidelines and address any feedback you've received.
I only have 1 question on my account and I haven't received any feedback! This is not community improvement; this is ostracism. How can you learn if you can't ask questions? How can you ask good questions if you don't have feedback? In all seriousness, what option do I have but to make a new account?
Here is the question:
In this paper: https://arxiv.org/abs/2201.11658 the authors discard unitarity in favor of isometry for the time evolution of quantum systems. In this alteration, they are able to show how time is a quantum error correcting code.
Furthermore, in this paper, since the motivation toward isometry is also directly linked to the expansion of space, it is clear that in this framework, this expansion is responsible for the creation of new information which is isometrically mapped to information in the past. Thus, the expansion of space is a mechanism for the creation of quantum information that encodes the flow of time. Therefore, it seems intuitive to me that spacetime curvature may arise from the regional differences in the rate of expansion. Since energy densities are known to cause spacetime curvature, I am wondering if the expansion of the universe is a default state from which energy densities necessarily depart in their expansion?
Are energy densities regions of spacetime that cannot expand at the same background rate as empty space and, therefore, do not produce as much information change as empty space does in its expansion?
