1. Gravity is a physical property of matter
1. Mass and energy bend space time
2. The bend is gravity
How black Holes work
Black holes have infinite energy density. This energy density is caused by the gravitational collapse of a massive star about 9 solar masses. The
energy density creates a black hole. But why, you may ask.
According to Einstein and Newton gravity is caused by matter and energy, so the more compact mass is then the more gravity it has.
When there is a gravitational collapse a star is compressed by the energy being attracted to the center of gravity within the collapse. The energy
and mass attract thus increasing their own gravitational pull by increasing their own density.
I may have confused some with the last part so let me say it again.
Energy and mass go to their center, thus pulling in more energy and mass increasing the density by increasing their gravity.
This is just to help those who have questions about gravity or black holes, because I think I'm pretty good at this subject.
p.s. if I am wrong on any part of this then feel free to correct me.
