The most impressive was not that Stephen Hawking wrote the history of time from the beginning of the universe. It was that he finally had a lot of time at his disposal, although when he was a student in 1963, at the age of 21, he was diagnosed with amyotrophic lateral sclerosis, also known as Lu Gear disease or motor neuron, his doctors gave him only two years life.
But Hawking, who never lost his British humor, despite his difficult situation, denied any expectation and lived to become the most famous scientist after Einstein. Even when neurodegenerative disease allowed him to shake only his eyes and a finger, his mental powers seemed flaky.
As one day said, “Although a cloud hung over my future, I found, to my surprise, that I was enjoying my life more presently than before. And then I started making progress on my research. ” His goal was simple, as he explained, “The complete understanding of the universe, why it is, and why it finally exists.” If this can be considered simple …
The black holes
From a scientific point of view, Stephen Hawking will rather stay in the time of science because he has raised an unusual question: When is a black hole not black? When it exploded, it was his answer.
His first scientific achievement, according to the Guardian, came in 1970 when, along with Roger Pennross, they applied the black hole mathematics to the universe and showed that there was a unique area of infinite curvature in spacetime, from where the original “Big Bang” (Big Bang).
In 1974, he used quantum theory to say that black holes emit heat, so they lose energy and eventually “die” in a very slow process that may take more years from the age of the universe. His suggestion that black holes emit radiation in the form of heat triggered a long controversy in cosmology. According to Stephen Hawking, this meant that all the information that falls in the black hole would be lost forever, which contradicts one of the laws of quantum theory, which has the effect of colliding with most of its colleagues.
Stephen Hawking then changed his mind and argued that the information was stored in the horizon of events of the black hole and turned into radiation again, emitted by the black hole. “I admit that maybe the loss of information is not happening,” he shouted a day with his electric voice to his students in a pub.
At the age of 32, he was elected honorary member of the Royal Academy of Sciences in Britain and five years later Professor of Mathematics at Cambridge University, Britain’s most famous university seat – if not all over the world – once owned by Isaac Newton and Paul Dirk. He stayed in this position for 30 years and then became research director at the Historical University’s Theoretical Cosmology Center.
1982 was one of the first to show that quantum fluctuations led – through the process of cosmic inflation – to the creation and spread of galaxies in the universe.
Although he did not – or did not – get the Nobel, he was honored with many other great prizes (Albert Einstein, Wolfe, Copley, etc.). He also liked to make scientific bets with other physicists, although he had a tendency to lose them, like, for example, when he lost $ 100 in 2012 because he had bet that he never would have discovered the Higgs boson – found at CERN shortly after!
