Thanks Daniel, Seems like I just saw on Nova where Stephen Hawking’s theory has not been disproven yet about some kind of separation of particles as matter approaches the event horizon. Sorry I can’t be more specific about the details. I guess he was the first to bring quantum mechanics into the big picture and show a relationship. Kind of a first step towards a unified theory which has eluded him for over 20 years. I misunderstood the article and thought the radio jet was coming from within the black hole; something I thought was a no no. It was a beautiful picture though.

The strong gravity of the hole is just like gravity anywhere it goes on out decreasing in strength by the inverse square law. In the accretion disk thing get pretty exciting because things get there by falling down a deep deep gravity well and their velocity or kinetic energy gets converted to heat when everything gets closer and closer together. A lot of heat. DT --- On Fri, 1/30/09, Jim Gibson <jimgibson00@yahoo.com> wrote:

To: "Utah Astronomy" <utah-astronomy@mailman.xmission.com> Date: Friday, January 30, 2009, 7:00 AM After I read Joe’s blog I went over and read Sheena’s. In reading her article on ‘Light from the darkness’ I realized I have missed a step (or 10) along the way in my understanding of black holes. On TV when ever someone is discussing black holes they always emphasize that the gravity in the black hole is so intense that not even light can escape from it. So, how do we get these radio jets escaping from a black hole as depicted in the galaxy Centaurus A? Jim
