Are black holes considered to be stars>
They are not considered to be stars, because they are the result of a large star's death. If they were, it would be a bit like saying a skeleton is a living being - it once was, but isn't anymore, and can't do the same things it did when it was alive.
No, black holes are not stars but stars of large enough mass can collapse and become a black hole. Stars, by definition covert and radiate energy through nuclear processes at the star's core. Black hole only emit Hawking radiation.
no, stars give off light, have a core, and are visible. Black holes are the exact opposite.
