Interesting article in the New York times this morning at: http://www.nytimes.com/2008/11/25/science/25dark.html Scientists believe they may have detected the results of two small masses of dark matter colliding and being destroyed. I found this interesting: "But if he is right, Dr. Wefel said that the ATIC data favored something even more exotic than supersymmetry, namely a particle that is lost in the fifth dimension. String theory predicts that there are at least six dimensions beyond our simple grasp, wrapped up so tightly we cannot see them or park in them. A particle in one of these dimensions would not appear to us directly." It spoke to one of the ideas being discussed here. Peace & Love!
