Reply to Black hole or A neutron star? by Brilliant-Fee-690
Mass. If it's massive enough, the star collapses into a black hole because the force of its gravity overcomes the forces that would otherwise prevent it from doing so.

When a white dwarf eventually burns out, it will turn into a black dwarf- basically a cinder in space. But the universe is too young for this to have happened yet. Black holes are the result of massive stars collapsing under the pressure of their own gravity once they can no longer resist it through the power of their fusion reactions.

I was just thinking about this. Are primordial gravity waves detectable in principle? If so, how much more precise do our detectors need to be to "see" them?
