**A Couple Questions...**

I was recently watching a t.v. show and the following terms came up: event horizon, singularity and schwarzchild radius... Can anyone tell me what these things are?

The event horizon is determined by the Schwarzschild radius and it refers to the point of no return for any object falling into a black hole.

A singularity (in this context) refers to the idea that all the mass of a black hole is concentrated at one point of infinite density - a prediction of general relativity. Since quantum theory breaks down under these circumstances, no one really knows what happens inside a black hole.

The Schwarzschild radius is the radius of the sphere around the (Scwarzchild) black hole whose surface forms the event horizon and is given by the simple equation:

[tex]r_S = \frac{2GM}{c^2}[/tex]

Ther singularity is the infinitely dense point at the centre of a black hole which matter is pulled to.
