Black holes could be considered self-sustaining in that physical properties are preserved, for example mass, charge, spin. Recent studies yielded the possibility that black holes can interact in a thermodynamic fashion with the universe and emit small amounts of a rather weak radiation (Hawking radiation) which carries energy and thus mass away from the black hole; in this manner they could shrink in size and eventually evaporate entirely. But at the same time they tend to accumulate additional mass through their gravitational field, hence there would need to be an imbalance for the mass not to be sustained.
stellar black holes were stars (these are large)primordial black holes were pieces of the big bang (these are microscopic)
No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.
Black holes do not die but they can evaporate.
Black holes are round because they are formed from dead stars and white holes. As you can guess a star is a sphere and that is why black holes are round.
There are no black holes in our solar system
They are called "black holes".
Yes. They get sucked into black holes all the time!
The most massive stars will die as black holes.
Schwarzschild black holes. Named after the scientist who proved mathematically black holes can exist.
Yes black holes are moving but they have no sense of direction..

Black holes were stars that were so massive that they collapsed on itself. The gravity in black holes is infinite and more you get closer to it, more time gets slower. Black holes suck all matter that is too close. Even light can't escape Black holes.
