Can black holes be considered stars?

[Gordon Freeman]

Objects like white dwarfs, black dwarfs, and neutron stars are all still stars, but are black holes the same?

[DiamondMiner10]

By definition a star is a luminous sphere of plasma which is held together by its own gravity and produces at least some light and heat. Black holes can produce light and heat but they are not plasma held together by gravity so they are not stars

[Gordon Freeman]

Neutron stars aren't really made of plasma, rather some abstract form of matter that we don't really know much about.


What is the state of matter in a black hole, then? Is it even matter to begin with?

[blotz]

Yes.

The state of matter in a black hole is like dividing by 0, it's indefinite. Why? Matter doesn't exist there, as its infinitely dense and infinitely hot and has infinite gravitational pull, so matter can't exist. So to ask what the state of matter in a place where matter simply cannot exist is pure insanity and contradicts itself. No insult to you, though.
