Black Holes 101
Everything you need to know about Black Holes!
How Black Holes Form!
A black hole forms when a super-giant star or a hyper-giant star lose's all of it's energy. The star's energy did counter-act the star's gravity, so when the star lose's energy it collapse's. The star shrinks down to a singularity (so small we don't understand). Since this singularity is so dense and small it gains infinite gravity (Out of our understanding).
This is a hyper-giant star named VY Canis
Cygnus X-1 is the first black hole ever identified. Cygnus X-1 was discovered by Tom Bolton in 1972.
Cygnus X-1's companion star being gravitated to the black hole.
