No, they form whenever a star dies, which can happen from two seconds after another black hole forms, or it could be 100 years before the next one forms. Point: They form at random.
Answer:
Contrary to the previous answer black holes do not form every time a star dies. For the formation of a black hole the star needs to be large (in terms of stars as a whole - our own Sun is too small to become a Black Hole).
no because black holes can only form through supernovas.
The black holes from Gamma ray usually burst because of their energetic form.
Probably stellar mass black holes
Black holes are sort of the final stage of stellar evolution; they don't form much else. Two black holes may merge to form a larger one, and after a very, very long time, they will evaporate.
Most black holes form when massive stars exhaust their fuel and their cores collapse. There are also supermassive black holes at the centers of most galaxies. Scientists are not sure how supermassive black holes form.
The energy that comes from black holes is called Hawking radiation.
Most black holes are believed to form when very massive stars die.
Black holes are outside the confines of both the Earth and the Solar System, the passing of our year does not affect when they form.
Yes. When the most massive stars die, their cores collapse to form black holes.
If five black holes came together they would merge to form a single black hole with a mass equal to the sum of the masses of the five original black holes.
Mostly the center of the galaxy.
No. Most black holes form when an extremely massive star dies and the core collapses, becoming a black hole.
