... Bad Astronomy . ... Bitesize Astronomy . ... Last week's Snack talked about how black holes can affect the environment around them in such a way as to be very bright . ... It's a common misconception that black holes always have matter swirling into them. ... As this matter gets closer and closer to the black hole it piles up and a large, fairly flat disk forms. This is called the accretion disk , because matter from this disk accretes (that is, falls in) on the black hole. ... 2008 Phil Plait. ...

... While space seems to be expanding at present (just as in our own universe), this expansion seems to be a recent phenomenon: in the past it appears to have been contracting. Data It is now clear that fuzzballs are actually galaxies. ... For the brightest fuzzballs, those from which we detect more than 100 photons per second, the pattern seems to match what we would expect. The fuzzball galaxies are indeed redshifted, and the fainter ones are more redshifted than the bright (nearby) ones. ...
