It is believed that they usually start from the gravitational collapse of a massive star - once it runs out of fuel.
stellar black holes were stars (these are large)primordial black holes were pieces of the big bang (these are microscopic)

Black holes do not die but they can evaporate.
Black Holes are created when stars above a certain mass start collapsing in on themselves. They're mass affects space time and they become a small point in space with an unimaginably large amount of gravity.
There are no black holes in our solar system
They are called "black holes".
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.
If two black holes started pulling on each other simultaneously, they would accelerate towards each other due to the force of gravity. As they move closer, they would reach a point where they start orbiting around each other in a process called binary black hole formation. Eventually, they would merge into a single more massive black hole, releasing energy in the form of gravitational waves.
