The origin of the elements was a big question that scientists were trying to tackle 50 years ago, and Fred H and his colleagues thought that supernovae maybe a key to unravelling the mystery.
At the time this was a radical idea, but Fred H was never a stranger to controversy.
Fred H blows up stars by computer, this cosmic * is the most controversial of theorists.
If you think there is a mystery about why stars explode, then you got it all wrong.
H devoted 10 years of his career to proving his revolutionary theory on the origin of the elements, he deduced that red giants are alchemists, but he knew that they weren't hot enough to create all the elements, he thought the ferocity of the supernovae explosion though would make them the ... |
