A black hole does not create a star. A black hole is formed when a star dies.
A black hole originated as a star, that is, the star converted to a black hole.
A neutron star or a pulsar, or a black hole.
No. A black hole will remain a black hole. A neutron star is a remnant of a star not massive enough to become a black hole.
The mass of a black hole increases when something else falls into it. That is frequently another star. It could be a planet.
The collapses star gets squeezed by collapses gas and turns into a black hole.
Not necessarily, but the likelyhood for matter from one star falling on the other and increasing its mass beyond the threshold for a black hole might be a bit larger than usual.
Yes black hole is last stage of a star
Yes. A black hole is a collapsed star.
That refers to a black hole - but a black hole is not exactly a star.
If it was not a huge star, it will probably become a black dwarf. If it was a huge star, there is a chance of it becoming a black hole.
If a star was "too close" to a black hole, that star would be captured by the black hole's gravity and be pulled into it.
A black hole can't really form inside of another black hole. If you think of a black hole forming after a star goes supernova, then there isn't really a star to go supernove inside of the already created black hole. In fact, there isn't even any space inside of the blak hole for anything to happen. Two black holes can join together, but they wil eventually go to one.
