Black hole singularities
WebApr 8, 2024 · Black holes are often called singularities for this reason. Their size would be shrunk down to a mathematical point. Instead, a black hole would have what is known as an event horizon. ... Black holes have an important part to play in the creation of galaxies and might even be part of the solution to the riddles of dark matter or dark energy. 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.

The fact that General Relativity predicts that singularities are inevitable under certain conditions is proof that GR is wrong. A singularity is an infinity and a place where the equations of GR literally break down and become meaningless. (Infinities are decidedly unphysical!)
WebThe black hole singularity always lies on the future light cone, whereas astronomical observations clearly indicate a hot Big Bang in the past. The possibility that the Big Bang is actually a white hole remains. The major assumption of the FRW cosmologies is that the universe is homogeneous and isotropic on large scales. WebAug 1, 2024 · One possible interpretation of this result is that the semiclassical treatment is making the second asymptotic region of the eternal black hole into a singularity, which is now in causal contact with the relevant asymptotic region, becoming a naked singularity (it appears that to recover the asymptotic flatness of the second region, one would …
