Black holes have infinite density
WebDec 8, 2009 · At the center of a black hole lies the singularity, where matter is crushed to infinite density, the pull of gravity is infinitely strong, and spacetime has infinite curvature. This means that a black hole's mass becomes entirely compressed into … http://insidescience.org/news/black-hole-cores-may-not-be-infinitely-dense
Black holes have infinite density
Did you know?
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. 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.
WebBlack holes of stellar mass form when massive stars collapse at the end of their life cycle. After a black hole has formed, it can grow by absorbing mass from its surroundings. Supermassive black holes of millions of solar masses ( M☉) may form by absorbing other stars and merging with other black holes. WebApr 10, 2024 · That theory says a black hole’s core is a point of infinite density and pressure called a singularity.This, says Chris Pearson at RAL Space, Britain’s national laboratory for space research,is a mathematical impossibility.A host of more palatable alternatives have been proposed, but none has the observational evidence needed to …

WebMay 17, 2012 · As energy can be converted into mass, the immensely high gravitational energy in this extremely dense state would cause an intense production of particles, greatly increasing the mass inside the black …
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.
