The effect of time dilation Shapiro confirms the theory of relativity Bashny.Net

There are several reasons why people may respond to the theory of relativity with bewilderment. It is difficult to imagine the idea, described by Einstein - for example, that the presence of mass-energy warps space-time, especially when you consider that prove the fact of such strain is almost impossible.

Einstein's theory states that an object larger size will create large deformation. This in turn means that the light may be inhibited depending on the objects that are in its path. In 1964, astrophysicist Irwin Shapiro managed to test this theory on the scale of the cosmos.

Initially the experiment Shapiro meant monitoring the distant stars, and how change other objects in contact with them.

For example, would seem like a star passing through the point of intersection with the distant Sun, will begin to move randomly in space as the sun passes in front of him. Since the light from the star is moving toward the Sun, there will be a visual effect that our star will move to the so-called poluorbite - like boat in a whirl - and eventually continues on a new trajectory. This path will cross with the Earth, and show that the star is in a completely different place than where we saw her for the first time.



But such calculations include a number of variables, so observe such an effect on distant stars was difficult - after all, the possibility of the telescope are not limitless. And Shapiro invented a new way to test this idea. He sent radar signals in the direction of Venus and Mercury, and watched how long it takes the signals to return to Earth. Shapiro did it several days in a row: as planets do not hang motionless in space, the position to get different experiment: to signals affect both the gravity and the planets and the sun. The more the arc through which the signal had to go to achieve all the objects, the more time it takes to his return. It should have been easy to calculate the delay time - and thus confirm the theory of relativity.

Latency is just 200 microseconds, but it was enough. This meant that the mass of the Sun is really delaying the light returning to Earth.

Shapiro Experiment, also known as the gravitational signal delay, was later checked more than tenfold. As time technologies are getting better, the scientists are now getting more and more accurate results. This is - one of the classic examples that prove the general theory of relativity.
