Formation of Black holes
- During most of the life of a normal star, over many billions of years, it will support itself against its own gravity by thermal pressure, caused by nuclear processes which convert hydrogen into helium.
- The explosive force of nuclear fusion inside them creates outward pressure which is constrained by gravity pulling everything inwards.
- Eventually, however, the star will exhaust its nuclear fuel. The star will now contract.
