That’s far too small for a black hole to have formed according to conventional gravitic black hole cosmological theory. Such a small star could not form a black hole. At twelve solar masses, it doesn’t have enough mass to do it. There are far larger stars with much more mass that do not have enough to form a black hole. So what gives??? There is something else going on 1,550 light years away from us other than a black hole.
“hat’s far too small for a black hole to have formed according to conventional gravitic black hole cosmological theory. “
The smallest black hole discovered is 3.8x the mass of the sun.
“There are far larger stars with much more mass that do not have enough to form a black hole.”
A star will not form into a black whole till it has burned itself out.
I don't think that's correct. Wikipedia says that stellar-mass black holes can be as small as 5 solar masses. Saying the black hole is 12 solar masses does not mean that the star that produced it was only 12 solar masses; a lot of mass is blown into space by the supernova.
