I used to be under the impression that black holes do not gain size, and that all of them are the same size, no bigger than an atom, but their gravitational fields varied.
and also that any matter coming towards them would Spagettify into a line of molecules and then they would be converted to Hawking radiation. But know I am hearing about theories such as black holes are just concentrated bodies of Dark energy, or that they are some form of worm hole.
I need a second opinion.
