Schwarzchild discovered that black holes were possible in the [[theory of relativity]]. [[Albert Einstein]] tried to re-work the whole theory to eliminate the need for these [[Singularity|singularities]].  However, [[Roger Penrose]] and Stephen Hawking proved the first of many [[Singularity Theorems]], which states that singularities must form under certain conditions. This demonstrated that, rather than mathematical oddities, singularities are a fairly generic feature of realistic solutions to [[relativity]].  According to relativity, any mass with radius less than its [[Schwarzchild Radius]] is a black hole.

But contrary to popular myth, a black hole is not a cosmic vacuum cleaner. In other words, a one-solar-mass black hole is no better than any other one-solar-mass object (such as, for example, the Sun) at "sucking in" distant objects. However a one-solar-mass black hole carries the same amount of weight as any other one-solar-mass object in a much smaller space.

However, a one-solar-mass black hole has the same amount of matter as any other one-solar-mass object but compressed into a much smaller space.
