How big is a black hole singularity
Did you know?
When a spherical non-rotating body of a critical radius collapses under its own gravitation under general relativity, theory suggests it will collapse to a single point. This is not the case with a rotating black hole (a Kerr black hole). With a fluid rotating body, its distribution of mass is not spherical (it shows an equatorial bulge), and it has angular momentum. Since a point cannot support rotation or … Web20 de abr. de 2024 · The most common way to form a black hole in the Universe is to have a massive star reach the end of its life and explode in a catastrophic supernova.
