 The evidence suggested that billions of tons of matter from a massive star had shrunk to nothing.So what we are left with here is this mind-boggling idea of mass contained in zero volume, and that just make your head spin, but that's what we call a black hole.


It's these very qualities that make some scientists think understanding black holes could hold the key not to death but to the birth of the very first stars.
It's really an awe-inspring story, much more so than the classical creation myths that make it seems so easy.
Scientists had discovered that there was one other place you can find a point of infinite density 1 and zero volume, that's at the instant the universe began, a moment studied by astronomer 2 Dr Allen Dressler, today it's scientific orthodoxy, but it wasn't always that way.
The idea that the universe had a creation event from a scientific perspective was a revolutionary idea, every bit as remarkable 3 a revolution as the idea that the sun and not the earth was the center of the solar system.
