- TL;DR Summary
- Stars contain mass. Gravity has a proportionate effect on that mass. When the star runs out of fuel, why doesn't the gravity reduce as the burnable material reduces?
Stars have mass. This mass has a gravitational pull. The nuclear fission of the star pushes against the effects of gravity. Why doesn't the gravity reduce as the star burns more and more of the hydrogen/helium/carbon that it's made up of? In other words, how can a black hole be created when the majority of the star has been burned away? Shouldn't gravity reduce based on the amount of the star's mass that remains after all the fuel is burned?
Stars emit huge amounts of energy into space. We are alive because of some of that very energy from our own star (the Sun). As this energy is dispersed, wouldn't the mass of the star be lowering as the process of fusion continues? How can there be enough mass left after a star burns out, to cause a black hole?
