WebIn this week's live QA, I explain why a black hole can have infinite density but not infinite gravity. Does your perception of time change due to your mass, ... WebApr 1, 2014 · Even within black holes, the famous 'Singularity' may not have infinite density, but merely a finite density near the Planck value. This is how 'quantum gravity' is thought to regulate, or eliminate real physical singularities; something which ordinary general relativity is not able to do. I read it in a book Elegant Universe, by Brian Greene.

WebWe don't know. There's a chance that there is an infinitely dense singularity at the center. There is also the chance that there is a volume of some sort that is not infinitely dense, … WebWhen we say that everything reverts back to an infinitesimal point of infinite density “exploding”. We don't generally say that, though. At least, if "we" means "physicists" here. One reason why we don't say this is that the universe may be infinite in size, which means it was infinite in size at the Big Bang as well. 1. google handwriting for windows
If black holes have infinite density and infinite gravity then how are ...
Gravitational singularities are mainly considered in the context of general relativity, where density would become infinite at the center of a black hole without corrections from Quantum Mechanics, and within astrophysics and cosmology as the earliest state of the universe during the Big Bang. Physicists are … See more A gravitational singularity, spacetime singularity or simply singularity is a condition in which gravity is predicted to be so intense that spacetime itself would break down catastrophically. As such, a singularity is by … See more Many theories in physics have mathematical singularities of one kind or another.
