The definition of chance in the Spanish dictionary is: "A combination of circumstances that cannot be predicted or avoided." The definition doesn't prevent a result from always occurring; it simply dictates that it's something that couldn't be predicted or avoided. Could you be referring to...

Does any theorem or principle prevent it, or do you intuitively answer that it's not possible?. I also believe it's not possible, but I was wondering if something in the QM formalism prevents it.

I once asked about this, but the question wasn't understood. For example, in the case you present, does anything prevent one particle from being in one state and the other in the opposite state by pure chance? Suppose the above happens every time we measure—that is, every time we measure a...

I add a recent paper for this topic, https://arxiv.org/abs/2510.11921, "information paradox and island of covariant black holes in LQG".

What model are we talking about? "mathematical model physically realized in our universe" *Sorry if I wasn't very expressive. After reading Peter's answer, I have two questions: What model are you referring to that connects black and white holes? (Are you referring to the maximally extended...

What "black to white transition" proposes is that the final conditions of a common evaporating black hole (not at all exotic in principle) are the initial conditions of a white hole (this is the exotic part). The final object, as Ibix indicates, is called a remnant, and it is especially small.

Exactly, the paper concludes that black holes are not dark energy, it does so as indicated in the title by adding black holes in FLRW, but I admit that I don't understand many technical details.

A white hole is part of the maximally extended Schwarzschild solution in Kruskal coordinates. The consensus is that they are not physical objects, but I cannot agree that they are not theoretically interesting. A Kleinian spacetime (two temporal dimensions) also doesn't seem to be physical, but...

Kasparov said something about this a few days ago at an economic/political forum https://www.elmundo.es/internacional/2025/10/04/68e15e4321efa0b41c8b4575.html , comments on AI: "There are things that are beyond our ability to control. Progress cannot be stopped. People will continue to...

Looking at the entire conversation, it's as simple as correcting you and explaining the standard solution. Personally, I usually use those "first personal approximations", but I don't think the moderators acted or spoke disrespectfully. You have to familiarize yourself with the harsh language...

I've heard this many times too, but I think it's an outdated and unproven view of chess. We're clear that chess is a finite game; it was discussed here https://www.physicsforums.com/threads/possible-number-of-chess-games.1067754/ . In order to debate this, we don't really need to know the exact...

In that game, there comes a point where pawn development blocks any attack by black's, the rest of white's pieces can quickly enter the game. The distribution at a certain point is clearly favorable for white's. The way to combat this would have been from the beginning, knowing that his...

Personally, I found this very interesting. As a chess player, I've always wondered if there exists a finite, simple, and perhaps dynamic set of tips that, when executed, lead to only winning games. That is, if we divide the set of all possible chess games into winning games (for me) or...

No site is immune to this; it's common in all physics forums. To avoid problems, you have to ask knowing if your question is correct and practically knowing the answer. That ensures you're never censored for asking. But if you know the answer in advance and if an answer is correct, what are you...
