Time travel is a topic widely developed in science fiction. Situations like those that happen to Marty Mcfly or the Avengers are not part of reality. Although technically there is a person in the world who in the 1990s became the first person in the world to achieve a journey into the future.
It is about Sergey Krikalev, a Russian cosmonaut and mechanical engineer, who has an unusual and incredible story that only he can boast of. He traveled to the future due to a political-territorial situation that caused him to suffer at the time.
The story is this. We are in 1991, a time of cold war and high points of the downfall of the Soviet Union. Sergey had to go to the space station of his then country, MIR, as a flight engineer.
It arrived on May 19 and was expected to spend a few months in orbit around Earth. The crew he was traveling with was ordered to return and Sergey Krikalev chose in good faith to remain seated to meet the other crew and then return.
In the midst of this wait, however, the Soviet Union disintegrated, and replacement cosmonauts never appeared.
This means that Sergey spent from May 19, 1991 to March 25, 1992 alone in orbit. It orbited the Earth 312 days and 5,000 times.
And the trip to the future?
The Russian cosmonaut experienced an effect called time dilation, an element predicted by Albert Einstein in the theory of relativity. According to this concept, when one object moves faster than another, time slows down.
At the time, the station he was traveling in was moving at 7.7 kilometers per second, a situation that meant Sergey was living thousandths of a second faster than the population walking on the surface of the earth.
Years later, Sergey Krikalev continued to add to his flight hours by traveling to NASA’s International Space Station (ISS), where he logged a total of 803 days, 9 hours and 39 minutes away from Earth. This means that the cosmonaut is technically traveling 0.02 seconds into the future.
