How fast does a black hole expand
Web14 mrt. 2024 · The theoretical density of a black hole depends on how big it is and how you define its size. The density at the center of a black hole is infinite (it's a famous "singularity" [1], which leads to difficulties in modern cosmology). On Earth, densities range from 10 -4 g/cm 3 for light gases to 0.001 g/cm 3 for aerogels and up to the heaviest ... Web28 dec. 2015 · 7. Most † black holes are indeed expanding, but not because the Universe is expanding. Rather, their size (more precisely their Schwarzschild radius) increases proportionally to their mass, so they grow as they accrete more matter. It is a common misconception that everything expands along with the expanding Universe. It doesn't.
