Stephen Hawking, holes and time history

Stephen Hawking, holes and time history

Stephen Hawking, a British theoretical physicist, is known for his attempts to combine general relativity with quantum theory and for his contributions entirely related to cosmology. Hawking has a privileged brain, like few others.

Stephen William Hawking was born on January 8, 1942 in Oxford, England. His parents' house was in North London, but during World War II Oxford was considered a safer place to have children. When he was eight years old, his family moved to St Albans, a town about 20 miles north of London.

At eleven, Stephen went to St Albans School, and then to the University College in Oxford, his father's old school. Stephen wanted to do Mathematics, even though his father would have preferred Medicine. As Mathematics could not be studied at the University College, he opted for Physics instead. After three years and not much work he was awarded the first class degree with honors in Natural Sciences.

Stephen then went to Cambrigde to investigate in Cosmology. After earning a PhD in Philosophy, he became a Researcher, and later Professor at the Gonville and Caius Senior Colleges.

After leaving the Institute of Astronomy in 1973, he entered the Department of Applied Mathematics and Theoretical Physics, and since 1979 he has held the position of Lucasiano Professor of Mathematics, occupied years ago by Isaac Newton.

Stephen Hawking has worked 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. Such results indicate the need to unify General Relativity with Quantum Theory, the other great scientific development of the first half of the twentieth century.

A consequence of such unification was that the black holes were not totally black, but could emit radiation and eventually evaporate and disappear. Another conjecture is that the universe has no borders or limits in imaginary time. This would imply that the way in which the universe began is completely determined by the laws of science.

Later he refined this concept considering all these theories as secondary attempts to describe a reality, in which concepts such as singularity have no meaning and where space and time form a closed surface without borders. He has written History of Time: from the Big Bang to Black Holes (1988) and other works that have become best-sellers. Hawking has made important contributions to science while fighting amyotrophic lateral sclerosis, an incurable disease of the nervous system. In 1989 he was awarded the Prince of Asturias Award for Concord.

Professor Hawking has twelve honorary doctorates, he has won the CBE in 1982 and was appointed Honorary Partner in 1989. He is the recipient of numerous awards, awards and medals and is an Honorary Member of the Royal Society and the US National Academy of Sciences. . Stephen Hawking combines family life and his research in theoretical physics, along with an extensive travel and conference program.

Hawking has also developed a series of predictions about the dangers that could end Humanity: artificial intelligence, human aggressiveness and ... aliens!

In the words of the scientist, "If the aliens ever visit us, I think the result would be like when Christopher Columbus first landed in America, which didn't turn out well for the natives"The British scientist believes that extraterrestrial civilizations would reach Earth to conquer or colonize it.

Endowed with a fine irony, his theories and statements have been almost always surprising and often misunderstood. In one of his last appearances he stated that "what existed before the big bang was basically nothing"That is to say, nothing that could exist before has anything to do with what came next. Therefore, it cannot be contemplated in any theory. At the time of that great explosion, the universe was a singularity, where all Physics laws would cease to apply.

Professor Stephen Hawking, the physicist who revolutionized science and our way of understanding the Universe, died at his home in Cambridge on March 14, 2018, at 76 years of age.
