How are Black Holes Created?
Some black holes are made by dying stars. When a star is alive there is an equal balance of gravity and pressure. When the star dies out the core pushes out collapsing under its own weight causing a black hole. Look here for more informatio... Read More »

How are Black Holes Made?
One theory on how a black hole is made is that a very large 50 to 100 times the mass of the Sun) star dies. The star must deplete all of its fuel for nuclear burning in its core which will cause the star to collapse under its own weight. Wh... Read More »
