Stephen William Hawking (1942 - 2018) has been an eminent theoretical physicist, astrophysicist, cosmologist and world-renowned British scientific disseminator for his work on spacetime singularities in the context of general relativity, and the theoretical prediction that black holes emit radiation (Hawking radiation).
Stephen Hawking he worked all his life on the basic laws that govern the universe. Together with Roger Penrose, he showed that Einstein's general theory of relativity implies that space and time must have a beginning in the big bang and an end within black holes. I work for unify general relativity with quantum theory, the other great scientific development of the first half of the twentieth century. A consequence of such unification that he discovered was that black holes were not totally black, but could emit radiation that could eventually evaporate and disappear. Another conjecture is that the universe has no time limits as we imagine it. This would imply that the way in which the universe began is completely determined by the laws of science.
He wrote numerous informative books on science, some were very popular, like the famous book "Brief history of time, from the Big Bang to black holes ", published in 1988 and has been the best-selling science book in history.
Hawking suffered a severe disability due to degenerative amyotrophic Lateral Sclerosis (ALS), which fortunately did not prevent him from maintaining his high scientific and public activity and has made him a reference of motivation and improvement for many people.
Today we bring you here the most brilliant and often sarcastic phrases of Stephen Hawking.
