British theoretical physicist. He studied mathematics and physics at University College, Oxford, where he graduated in 1962. In 1966 he received his doctorate at Trinity Hall, Cambridge. In the early sixties had the first symptoms of amyotrophic lateral sclerosis (ALS), degenerative neuromuscular disease that has not stopped her progress in intellectual.
His scientific interest is focused on the field of general relativity, particularly in the physics of black holes. In 1971 he suggested the formation, after the big bang, many objects, called "mini black holes", which contain about one billion metric tons of mass, but occupy only the space of a proton, a circumstance that would cause enormous gravitational fields governed by the laws of relativity.
In 1974 he proposed, according to the predictions of quantum physics, that black holes emit subatomic particles to deplete your energy, to finally explode. That same year he was elected to the Royal Society; three years later he was appointed professor of gravitational physics at Cambridge, where two years later he won the Lucasian chair of mathematics, the same who took Isaac Newton.
His efforts to describe from a theoretical point of view the properties of black holes, and the relationship that these properties saved with the laws of classical thermodynamics and quantum mechanics, are reflected in his works The Large Scale Structure of Space- time (1973, in collaboration with GFR Ellis), Superspace and Supergravity (1981), the Very Early Universe (1983) and the best-selling Zoya (1988).
