On the day of Pi, March 14, 2018, died Stephen Hawking, a physicist and popularizer of science. In 1969, doctors diagnosed him with amyotrophic sclerosis and predicted a maximum of two and a half years for him to live. But the scientist lived another 55 years, having managed to form for himself and humanity the Theory of Everything.

Above all, he was interested in global physical processes, history of the universe, the relationship between men, universe and time. Hawking is often called the founder of quantum cosmology; he managed to shed the light on such a mysterious phenomenon as black hole.

Universe and Time

Stephen Hawking often spoke of the universe and time and some of his statements seemed strange and unusual. For example, he said that the past is as indefinite as the future. Hawking argued referring to the theory of quantum mechanics that events that took place in the past did not occur in a certain way.

It does not matter, the scientist said, what a person remembers about a certain moment of their past. It is just as vague as the future, that is, it is a spectrum of possibilities.

About the creation of the universe, Stephen Hawking said that it created itself from nothingness. He saw no need for God. He dedicated a lot of time and brought scientific evidence to support this version. Stephen Hawking considered some higher power in the process of creating the world a theory with no scientific basis.

The most important discoveries

Most of his discoveries concerned the universe, space and time.

  • Together with a mathematician from Oxford Roger Penrose, he provided evidence that the Big Bang, if it took place, began with a singularity – an infinitely small point.
  • Black holes do not only suck in everything that comes close to them. They also emit energy, which is called the Hawking radiation. Because of this, the black hole eventually loses its mass. This is due to the quantum processes near the event horizon – the edge of a black hole.
  • In the 70s, the scientist was interested in the possible disappearance of light particles after they hit a black hole. At first, he was convinced that the light completely disappears. Physicist Leonard Susskind started a scientific argument with him. Only in 2004, Hawking admitted that the information is preserved. This discovery was called an information paradox.
  • Together with his colleague James Hartle, the scientist tried to put a description of all the history of space into one mathematical expression. It was called the Hartle–Hawking state (the wave function of the Universe). According to the quantum theory, the differences between space and time are fuzzy and blurred. So it turns out that everything before the Big Bang does not matter.

Hawking’s Theory of Erotica

Stephen Hawking was a gambler and loved scientific bets on the subject of black holes. He bet mainly annual famous erotic magazines subscriptions. Since it took place in the 70-80's, such magazines were valuable.

The bets could last for decades. It is interesting that Hawking lost almost all of them and acknowledged that his opponents were right. After that, he corrected his scientific theories.

Predictions

Stephen Hawking believed that the time given to humanity to live on Earth is getting shorter. In his opinion, the last person on our planet will die somewhere in the 27th century. To save the civilization, humans must move to other planets. We need to move towards Alpha Centauri – a close star system, where, as Hawking believed, there are habitable planets.

According to Hawking, black holes could be portals to parallel universes. Although, he believed that the object that got to the other side could change completely. The physicist also believed that people would soon be able to create black holes themselves.

Both scientists and the general public look at Stephen Hawking’s ideas in very different ways. But one thing is for sure – his theory occupies the minds of people because he not only made extremely important scientific discoveries, he also explained them to people in understandable terms.
