The Bardeen black hole also evaporates via Hawking radiation, but whether the process is unitary seems to depend on adding backreaction, at least in the case of regular black holes (Bardeen-like model) in 2D dilaton gravity. https://arxiv.org/abs/2503.03191

Can I ask you for references on this again?

https://arxiv.org/abs/2412.02742 "Dynamical formation of regular black holes", Pablo Bueno (Spain). In this case, they construct the black hole using a tower of infinite corrections. Regular black holes are those that have neither a real horizon nor a singularity; Bardeen's black hole is a...

Could you provide a reference on this? I'm not aware of any that demonstrates the absence of an information paradox in Bardeen black holes. I recall physicist J. Edelstein saying that the information paradox also exists in regular black holes; there is still a black hole and trapped information...

I want to highlight one point: in warp, the energy conditions are violated, and it is precisely the violation of the energy conditions that produces the effective displacement. https://arxiv.org/abs/2103.05610

Isn't there a 1960 work by Stueckelberg where he constructs a version with real numbers?

My opinion is: "shut up and calculate"

Is it correct to say that in the case of the Schwarzschild black hole the source of curvature is hidden as a Dirac delta at a point? The singularity is more like a moment in time than a place in space, ok. Ricci tensor=0 and non-zero Riemann tensor, therefore curvature exists despite being a...

Not every case where a minor kills someone ends up being considered the parents' responsibility from a legal standpoint. There are cases where it is determined that they are, and others where it is determined that they are not. The circumstances vary widely. If parental influence can be proven...

I was thinking about this interesting question you raised. The answer is yes, up to a point. As long as we're talking about AI and operators, the operators are responsible. But beyond the point where AI is autonomous, we can't hold the creators responsible. It would be like punishing a parent...

I reconstruct the sentence then: "the feeling I get is as if we took BM and changed everything written in English to Spanish, and then said that the result is a new interpretation..."

The feeling I get is as if we took Copenhagen and changed everything written in English to Spanish, and then said that the result is a new interpretation.... What do you mean by interpretation? (Many Worlds and Copenhagen, while describing the same thing, are based on remarkably different...

Perhaps the term "formalized" wasn't the most appropriate. I'm not comfortable claiming that the idea of eternal inflation implies a level 2 multiverse and that this is theoretically proven. Some authors say yes, and others say no; there's no consensus. It's true that those who say yes often...

For example, a reference from one of the greatest physicists, https://arxiv.org/abs/1707.07702 (S.W. Hawking) "Based on this we conjecture that the exit from eternal inflation does not produce an infinite fractal-like multiverse, but is finite and reasonably smooth."
