Hi, sorry if you see any mistakes, its not my mother language
i have a theory came to my mind about gravity
if super massive star have huge amount of gravity, thats what we know
it explodes, and loose around 95% of her mass, doesnt mean that core mass should weaken?
that means the gravity it self is not affected by star, it affected by the matter in space and star forms, on gravitational “hole” on that place
then all around it makes sense, because after supernova it should loose mass, not become a black hole
what you guys think about it?
