Anatomy of a Black Hole

Justin Stafford's insight:

Stars like our sun turn into red giants where as larger stars turn into red supergiants in the second stage of their life once all the Hydrogen has been fused. The stars are similar up to this point the big change happens when all the helium has been fused. The gravitational forces outweigh the expansion forces, the star contracts. The more massive stars then explode releasing lots of energy and matter which is called a supernova, leaving behind a black hole if massive enough and the smaller stars like our sun dont throw off their matter and become white dwarfs or neutron stars.

Justin Stafford's insight:
