For many centuries, it seemed to people that time moves everywhere with the same speed. The difference in time in space and on Earth was not taken seriously, but Albert Einstein changed everything in his theory of relativity. All respected scientists in the world of physics could not fail to take note of this view, so this area has completely changed in its ideas.
The importance of the theory of A. Einstein
Initially, Einstein's theory was called "On the electrodynamics of moving bodies." She received her final name later, when scientists completely studied it and realized that to a greater extent this theory considers relativity. Such a topic has remained unexplored for thousands of years, so the importance of it is undeniable.
For example, if a person is in the water and throws a stone into the distance, then he won’t feel much difference. If he floats, then a change in movement will be visually noted.
The theory helped explain the difference in time in space and on Earth.
Main conclusions
If you do not directly study the whole theory, you can deduce from it certain facts that are related to space and time in space and on Earth. These two concepts are inseparable in essence.
The two most important conclusions of this theory are the curvature of space and time under the influence of gravitational fields. Such a process is evident in the movement of all bodies.
Thus, we can say that if an object moves with a certain speed, then physical phenomena will show themselves much more slowly. If the body is at rest, then the effect will be the opposite.
Say, if a person is traveling in a car, and his friend is at home, then the first one will feel the movement of time much more slowly than the second. Both the difference in such situations, and the time difference between the Earth and space, is quite difficult to feel, because it is insignificant, literally billions of a second.
But if the speed changes both in the first and in the second object, then the difference will have large indicators. If a rocket flies in space for about one year, then on Earth over this period will take about several hundred years.
Example
An example does not mean that a person in a rocket will feel a serious difference in time in space and on Earth. His usual actions will not become slow, they will go in the usual way.
For a person from Earth, this, of course, will be perceived differently if he can see another at that time in a rocket.
Despite this, the object in the rocket will also think that the period on Earth is calculated very slowly if he could see the clock there.
How is time in space relative to the earth? After all, not all people feel the difference. The fact is that a person in a rocket feels time relative to himself, therefore, he feels some changes. It seems to him that the speed of his time is much greater. This is also due to the serious acceleration of the rocket, due to which the unit does not move linearly like the Earth. Accordingly, the reference system is not equal at both points. It is for this reason that man in space believes that he is moving faster, and earthly inhabitants almost do not notice the difference.
The curvature of space and time as a cause of relativity
Each body, in this case, it is a rocket, having its own specific speed, somehow bends time and space around itself. This is noticeable even if an object moves faster with a small object on the table. True, this period is very difficult to calculate mathematically, since it has meager indicators.
But the time on Earth and in space differs significantly, so the value is not so difficult to find. This is because the mass of objects is large, respectively, space and time they bend to a greater extent. The difference in performance is easy to feel thanks to modern equipment. The gravitational field of the dimensional objects is strong, because of this, the time is calculated much more slowly.
A similar fact takes place in a number of studies that confirm it.
Everyone can believe the data without having specialized equipment. It is enough to take a small ball, and then hit it. Initially, its movement will be directed along the line, and then the trajectory will change, it will appear that the object itself is changing its movement. But this is not so, since the gravity of the Earth itself causes the ball to change direction, but the quality of movement does not change. Later, the moment will come when the line of motion of the Earth and the sword itself will coincide.
Destruction of stereotypes
Judging by what has been said, no one can say for sure what the difference in time is in space and on Earth. It is still unknown for certain that it is faster on Earth, and slower in space, or vice versa. This is because cosmos is a huge space, in each part of which time flows differently. Near a black hole, it becomes long, and away from planets and stars it speeds up at times.
Interesting Facts
Studies say that the relativity of time is a multifaceted and complex concept. For this reason, one cannot say for sure that in orbit the astronaut will feel time more slowly than the inhabitants of the Earth. For example, if you give the astronaut a clock and start it simultaneously with those that remained on Earth, then the result will be unexpected. A person who returned from space even after a year will look at the period of his absence, and the clock will show the time, which was calculated much faster than at the space station. But this will re-read the fact that he was at a greater distance from the overall cosmic body than the earthling.
Therefore, to unilaterally evaluate all the data in the theory of relativity is illogical. No wonder it is relative.
