The fact that there is a black hole in the center has been proven by measuring the photon emmisions and xray telescopes - there also seems to be a star that is in partnership with the hole right now which shows a pulsing exchange of matter/energy
Of course most of this is refuted by most scientists who havent really taken the time to look at it - most of them scoff at it as good meat for a movie (I think Mel Gibson has one coming out or already out about it) - unfortunately most of the scientists that post on the web as "astronomers" and experts - are really not even close - but at least they are getting good money getting their names before the cable news networks as "experts"
