Space Pioneer Sergei Krikalev, the most abundant timeline in the world
Is travel through time really or is it just a science fiction? Thanks to the expansion of the time and Einstein theory of relativity, we know that travel through time can actually happen, albeit only with very small increases in speeds and distances that we can travel in space. If you add accumulated fast astronauts, Sergei Krikalev traveled in space-more than any human being with the total time spent in the course of 803 days 9 hours and 39 minutes-he has already moved to his future by 0.02 seconds.
The expansion of time occurs due to the differences in gravity or relative speed - each affects time in different ways. When astronauts and satellites revolve on Earth, they are a little away from the middle of the planet - intended for people on Earth - and therefore they actually suffer from the expansion of less attractive time. This means that the time of astronauts will continue a little faster, and when they return to Earth, they must "return" to the past compared to the time they were in space.
But the expansion of time due to the speed means that the watches of astronauts in space work slightly slower for the people on Earth. When you return to the ground, you should go to the future a little to catch up with hours on the ground.
Sergei Krikalev, he was longer than he spent a time in space than human beings, where he spent 803 days, 9 hours and 39 minutes, which made him travel to his future for 0.02 seconds!
In the end, we all travel through time according to the relative theory, but the effect is so small that it is not perceived. Once you leave your friend standing in his place, and start walking, your time will slow down according to your friend's point of view. Also, as soon as you move from one point on the ground, to another point that differs from it by height, such as ascending to the second floor of building what, for example, the flow of time your time will become faster, but in a very small and impact manner. This is what prompted me to say at the beginning of the article that there is at least a person who travels over time, but the truth is that we all have done it, but we simply do not notice the matter because he is only imperceptible!
