Amazing; Paul is an old school wingnut of the "secret government ufo factories" type; I seem to remember one of his claims that the stealth bombers were powered by antigravity engines. WTF Today Show? Can you not just interview an astronomer or astrophysicist on this subject? Evil.
There was a documentary about this a couple years ago. Only they were theorizing the existence of just such a phenomenon. It has to do with shit getting sucked into a black hole. So, score one for the "black hole at the centre of the galaxy" theory.
