From CNN:
"(CNN) - Scientists have discovered a "monster black hole" so massive that, in theory, it shouldn't exist.
It's a stellar black hole — the type that forms after stars die, collapse, and explode. Researchers had previously believed that the size limit was no more than 20 times the mass of our sun because as these stars die, they lose most of their mass through explosions that expel matter and gas swept away by stellar winds."
