You’re both wrong. Very massive stars do leave behind a black hole, and black holes don’t “collapse” like that. Rather, they evaporate through Hawking radiation, at a rate inversely proportional to their mass. Any black hole more massive than our Moon currently gains more energy from the cosmic background than it radiates. The smallest stellar-mass black holes won’t fully evaporate for at least another 10^80 years.
Oh yeah. Silly me. I knew that actually, just forgot it a bit.

I know. But a collapsing black hole would probably produce something akin to a supernova.
A supernova doesn’t leave behind a black hole
