What is a
black hole?
A black hole is an object so massive and dense that nothing—not
even light—can escape from its powerful gravitational field.
How are black holes formed?
Smaller black holes (about 10 times as massive as the Sun) are created
in supernova explosions, when the core of a dying star suddenly
collapses. Supermassive black holes hundreds of millions of times
as massive as the Sun are found at the centers of galaxies. Theories
about the formation of supermassive black holes vary, but they probably
grow so large by feeding on the mass that accumulates at galactic
centers.
What happens inside a black hole?
The science of physics is not yet advanced enough to know for sure
what happens inside a black hole. |
