1. Theories of Black Holes
... , including the particles of light known as photons. This radiation exerts an outward pressure that exactly balances the inward pull of gravity caused by the star's mass. As the nuclear fuel is exhausted, the outward forces of radiation diminish, allowing the gravitation to compress the star ... residue (largely iron) can muster. If the star is sufficiently massive or compressible, it may collapse to a black hole. The first person to discuss black holes was a Cambridge man by the name of John Mitchell. Mitchell argued that it was possible to have a star that was sufficiently massive and ...
