Black holes have infinite density

WebFeb 15, 2024 · In the center of a black hole is a gravitational singularity, a one-dimensional point which contains a huge mass in an infinitely small space, where density and gravity become infinite and space-time curves infinitely, and where the laws of physics as we know them cease to operate. WebJun 5, 2024 · There is an assertion that General Relativity predicts that black holes have zero volume, so by extension that their density is infinite. However, my understanding …

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 … WebMay 19, 2024 · A black hole singularity isn't a one-dimensional point. Its dimensionality is undefined. It doesn't have infinite density according to GR, because it isn't part of the spacetime manifold, so GR doesn't define whether there is any matter there. There is a notion of a strong curvature singularity. black and white checkered sheets https://starofsurf.com

WebFeb 15, 2016 · A singularity is a place of infinite density, and that's not really a thing. It just means that the mathematics that we're using to describe the thing have broken down. ... Could Black holes have ... 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. WebBlack holes are difficult to detect, because they are black.
