B Flat Black Hole Using the Chandra X-Ray Observatory, astronomers have found for the first time, sound waves froma supermassive black hole. The black hole in question, is in the Perseus cluster of galaxies, about 250 million light years from Earth. The sound the black hole makes translates to the bote B flat, but the note is 57 octaves lower than the middle C -- making it impossible for the human ear to hear it. This has some significance, as astronomers have long wondered why gas in galaxy clusters don't cool -- cooling gas would allow star formation, as it would allow gravity to exert its influence -- however, gas in galaxy clusters remain hot. Sound waves from black holes may be the mechanism keeping the gas hot.

South Park: Bigger, Longer & Uncut -- This is one hilarious movie -- but boy is it rude. It's rude beyond the point of being offensive. The movie takes the good taste filter off and amuses with humour that simulate the juvenile in us. Every now and again though, that little kid in us needs to be amused -- and this movie will certainly do that. If you're offended by the movie, it's because the adult in you is watching. The Brothers Grimm -- This was an OK fantasy movie, moving at a good pace, with the appropriate level of action and humour. The special effects were well done -- and so was the cinematography.
