I agree there is no evidence of this. But here is another mystery of physics. The radius of a black hole's event horizon is where the escape velocity equals the speed of light, Gm/r = c. For the universe, the radius is close to the size of the universe, r ~ Tc. So why did the universe (or large regions of it) not collapse into black holes when it was much younger and denser? I believe that an observer approaching a black hole in a free fall observes nearby objects accelerating away in all directions. -- Matt Mahoney, [EMAIL PROTECTED] ----- This list is sponsored by AGIRI: http://www.agiri.org/email To unsubscribe or change your options, please go to: http://v2.listbox.com/member/?list_id=11983
