The Problem with Black Holes - Sixty Symbols
Singularities, General Relativity and Quantum Theory - can't they all just get along? This is the third part in a little series we're doing on Black Holes... Featuring Tony Padilla and Ed...

The singularity, well I mean that's just something that we just don't understand.It's a singular point and that means the curvature of the spacetime atthis point is goneinfinite and all the mass is collapsed to one point. So it''s a pointliterally a point, with this mass in there. So it's got infinite density, you know a density is mass perunit volume, well if this got no volume, it's an infinite density. These black holesthat are defined, are defined in the sense of using General Relativity and this is thiswonderful theory of Einstein which explains how matter andcurvature of spacetime are intricately linked together. So you really need somequantum theory of gravity to try to describe that, so I'm sure that ...
