Having said that, is it true that black holes are holes in the fabric of space and time that are black?Despite the name, a black hole is neither a hole nor black - and this is explained in a YouTube video by Oxford University astrophysicist Dr Rebecca Smethurst.
Smethurst said that as such, black holes are invisible and can only be detected by the effect it has on the matter around it. Smethurst added that"if anything, it's the complete opposite. It's a mountain of matter crushed into such a small space so dense that the escape velocity is greater than the speed of light."
"After all, a dying star that collapses in on itself in a supernova is the only process that we know that can make a black hole. They become these prisons for light; dark stars," she said.
