Is a black hole a star?

Answer 1

It depends. Most black holes have masses comparable to massive stars, but their event horizons are much smaller, a few tens of miles across. Supermassive black holes can have enormous event horizons, some larger than our solar system.

Answer 2

A black hole began as a very large star. When this type of star goes into a supernova stage ("explodes" or "dies"), the core collapses in on itself, pulling inwards, and taking anything near enough with it. The density becomes theoretically infinite, as all of that mass becomes concentrated at a single point.

Answer 3

Every black hole at a certain point was a massive star(more than 3 solar masses).

At the end of its life it exploded into a super nova.due to its huge size it collapsed onto itself which formed the black hole.stars and black holes are two different types of entities,a black holes is the evolved stage of a star but not a star

Answer 4

no their not! but they are previous star because they are made from the matter of a dying star.... the matter on this star(not sure what kind of element) is so dense that it stretches the very fabric of space time...... x) i want to be an astronomer!

Answer 5

no. it is a collapsed star that didn't have enough mass to become a black hole. it still has a very strong gravitational pull.

Answer 6

Yes the actual explosion is called a supernova, and there is also an implosion involved in the making of a black hole.

Answer 7

Black holes were 'star'. When a star dies by crushing down its own gravity and then black hole forms.

Answer 8

black holes are dead stars
