On March 13, 2018, the world lost one of the most recognized and great men that science has had: Stephen Hawking. In his 76 years of life not only did he battle against a complicated disease, but he also made contributions to science and the theory of the universe with a passion that is rarely found.
It's hard for a scientist to admit mistakes and generate new ideas, but Hawking always refuted his own theories and fought for the truth behind them. Due to all the advances that he generated in the study of the universe, we honor him by reviewing his career and personal life.
8. Personal life
Stephen Hawking was a Ph.D. candidate at Cambridge when he was diagnosed with Amyotrophic Lateral Sclerosis, a disease that affected his motor functions. He married Jane Wilde, whom he met shortly before becoming ill. With her, he had three children, but they divorced in 1995. They both were married again.
7. In the university
Unlike what many of us think, Stephen Hawking did not spend the entire day studying. Apparently, the genius only used one hour of his day to study for the university and a large part in other activities.
6. The universe without limits
Contrary to what was thought at the time, Hawking postulated that the universe had no limits. About the origin of the universe he said that after the Big Bang several black holes were created, and that is why he decided to study them in depth.
5. Hawking radiation
Black holes were not taken into account in Einstein's studies of relativity, but years later Stephen Hawking decided to study them. He concluded that the event horizon of a black hole corresponds to the paths of the luminous rays that remain orbiting it, that is, they can not enter, nor escape from it. He related it then to entropy.
The conclusion reached by Hawking was that matter borrows energy from space by creating pairs of antiparticle particles that, once created, separate and rejoin, annihilating each other. If someone who could see the phenomenon would see that the black hole emitted a particle, corresponding to the Hawking radiation.
4. Stephen Hawking quotes
For being someone who lived a long time, even though his life expectancy was only 2 years, he was also able to develop a way of life and attitude that few have. This generated that for his work, and even his personal life, he had many phrases that are now famous.
3. Doubting his ideas
Hawking retracted numerous times of what he said and seemed never to be sure of what he was saying. For many, this is a fundamental question because it implies always being in search of the truth.
For example, for a long time he argued that when a black hole exploded the information was lost. After a controversy with Leonard Susskind he admitted his mistake and said he was going to prove that the information was in the universe, but unfortunately he did not have time to do so.
During his life, he starred in many controversies. For example, he claimed that Artificial Intelligence had the potential to exterminate humans. He considered that technology advances faster than the human mind, which is a problem. In addition, after years of doubts, he declared himself an atheist. He said that science offers all the necessary explanations, and therefore, there is no God.
1. The Theory of Everything
In December of 2014, the movie The Theory of Everything was released, which is about the life of Hawking since he met Jane, going through all his problems, his beginnings in science, and his family life. Although it does not deal in depth with the scientific question about the universe, it is an opportunity to know more about this scientist.
