The mathematics backing up the theory of black holes is referred to as the schwartzchild radius. The equation considers a black hole an object so dense its escape velocity exceeds the speed of light. the equation is
<math>rs=2Gm/C^2</math> where rs is the Schwarzschild radius;
G is the gravitational constant;
M is the mass of the gravitating object;
C is the speed of light in vacuum.
