How to Find the Mass of Black Hole

A black hole is original spacetime. It's not a tear in the fabric of space time. An infinity is unphysical. What is an infinity? You divide a number by zero. That's when you get infinity. So that s us that there is a flow or defect in the physics, in the equations of general relativity. We need a theory of relativity that brings together geometr dynamics of einstein and quantem theory,. Quantum field theory, quanted mechanics will combine these two to create a proper theory of quantum gravity.
