Cosmological Star.... Admirable person

The British theoretical physicist Stephen Hawking (1942-) has devoted much of his life to probing the space-time described by general relativity and the singularities where it breaks down. And he’s done most of this work while confined to a wheelchair, brought on by the progressive neurological disease amyotrophic lateral sclerosis, or Lou Gehrig’s Disease. Hawking is the Lucasian Professor of Mathematics at Cambridge, a post once held by Isaac Newton. In the late 1960s, Hawking proved that if general relativity is true and the universe is expanding, a singularity must have occurred at the birth of the universe. In 1974 he first recognized a truly remarkable property of black holes, objects from which nothing was supposed to be able to escape. By taking into account quantum mechanics, he was able to show that black holes can radiate energy as particles are created in their vicinity. But perhaps his most impressive feat was writing the international bestseller A BRIEF HISTORY OF TIME. The book spent more than four years on the London Sunday Times bestseller list—the longest run for any book in history.
