Black Holes No More -- Introducing the Gravastar
Mark Eymer observes: "From the Space.com article: 'Emil Mottola of the Los Alamos National Laboratory and Pawel Mazur of the University of South Carolina suggest that instead of a star collapsing into a pinpoint of space with virtually infinite gravity, its matter is transformed into a spherical void surrounded by "an extremely durable form of matter never before experienced on Earth."' While these objects may abound in the universe, they also say that our entire universe may reside within a giant gravastar." This new theory attempts to fill holes in the currently accepted concept of the "black hole".
Memory fading, but I'll be close...
The title comes from the retelling of a story in Carl Sagan's Broca's Brain where a 17th century philosopher/physicist (which one I can't remember) is giving a lecture on how the Earth moves in the Solar System, floating in space. A woman stands and claims the theory is ridiculous. She states everyone knows that the Earth rests on the back of a giant turtle. To which the scientist asks, "Well then, what is the turtle resting on?"
Her reply? "Very clever young man, but it's turtles all the way down!"
It's a great book.
