They're found at the center of almost every galaxy, and the singularity is about as small as an atom w/ infinite mass. The event horizon, or the point of no return is the area where nothing but negative particles escape as Hawking Radiation (Guess who found it) The only way we can see them is due to the matter surrounding them and being ejected, and their effect on close stars. They're formed by large stars that collapse in on themselves, and probably from the aftermath of the big bang.
Incorrect. Black holes have a
finite mass and an
infinite density.... This error is wayyyy too common and it burns my eyes whenever I see it (no offense of course).
Infinite mass would mean that there would be an infinite gravitational attraction between the black hole and everything else.
