Summary
Newton’s theory is nice but it’s not enough.
Einstein’s theory is even better than Newton’s.
Black holes are supermassive objects and we can apply Einstein’s theory to them.
Gravitational forces are very crucial in nature.

conclusion
“Gravity must be caused by an Agent acting constantly according to certain laws, but whether this Agent be material or immaterial I have left to the consideration of my readers.”
Isaac Newton
“Most of the fundamental ideas of science are essentially simple, and may, as a rule, be expressed in a language comprehensible to everyone”
Albert Einstein
