Sharp BlueRichard Baker's thoughts on history, science, technology, literature and the future.The causal structure of black holes, part two- May 15, 2008 In the previous part of what has now become an ongoing series on the causal structure of various general relativistic spacetimes, I discussed the causal structure of the flat, Minkowski spacetime of special relativity, and of the Schwarzschild vacuum outside a spherical, uncharged, non-rotating star which collapses to form a black hole. In this part, I'd like to discuss the so-called Kruskal extension of the Schwarzschild vacuum. This is the general solution for a static, asymptotically flat...http://www.theculture.org/rich/sharpblue/archives/000190.html |
