Stephen Hawking, English theoretical physicist and cosmologist who is universally considered to be one of the most intelligent scientists alive today. Currently, he is the director of research at the Centre for Theoretical Cosmology, University of Cambridge.
Quote: We are just an advanced breed of monkeys on a minor planet of a very average star. But we can understand the Universe. That makes us something very special.
Stephen Hawking has explored on the basic laws which govern the universe. With Roger Penrose he showed that Einstein’s General Theory of Relativity implied space and time would have a beginning in the Big Bang and an end in black holes. These results indicated it was necessary to unify General Relativity with Quantum Theory, the other great Scientific development of the first half of the 20th Century. One consequence of such a unification that he discovered was that black holes should not be completely black, but should emit radiation and eventually evaporate and disappear. Another conjecture is that the universe has no edge or boundary in imaginary time. This would imply that the way the universe began was completely determined by the laws of science.
