yes, as long as there are things that can fall into it, it can get bigger.
A galaxy is bigger than a black hole.
things dont implode in a black hole they are dragged in and the black hole gets bigger
I don't think that either of these stars "have" a black hole.
The quasar is bigger. A quasar is a disk of superheated matter that surrounds a supermassive black hole. The mass of the black hole may be greater than that of the disk, but it is compacted into a smaller space.
That's not exactly what happens. What really happens is that they just absorb each other and become a bigger black hole.
Maby the universe
Yes. The Schwarzchild radius of a black hole is directly proportional to its mass.
Yes. A quasar is a disk of superheated material that sour rounds a supermassive black hole.
The mass of the black hole would increase in proportion to the mass of the planet
First of all, our sun can not become a black hole, it is too small for that. However if a star is three times bigger than our sun, then yes it will become a black hole.
Yes, a black hole is usually a star that has been compressed to a point where the density is really high.
It depends, Black holes can go from being microscopic to supermassive black holes that entire galaxies revolve around. It all depends on which black hole and which quasar.
