Einstein was right to say time expanded

According to Einstein's special theory of relativity, a flying clock will tick more slowly than a stationary clock. And that is true, an international research group claims.

About 100 years after Einstein wrote that time runs faster or slower depending on the speed of movement of an object than another, scientists used a particle accelerator to prove that it was true. .

They then measured the time of these atomic beams with a high-precision laser spectrometer. When compared to the outside real world, they found that the movement time of atoms was indeed slower than usual.

"We were able to confirm this effect was never exactly true," said lead researcher Gerald Gwinner from the University of Manitoba in Winnipeg, Canada. "And in absolute agreement," he added.

The first experiment measured time dilation took place in 1938, when US scientists used the Doppler effect (the phenomenon of sound nuances of an object - such as a train whistle - changes when approaching or leaving. far away from listeners) for making measuring instruments.

Einstein's theory of special relativity became the basis for science fiction stories, as it opened up the prospect of bending and twisting time.

According to this theory, if one of the twins is launched into space at a very high speed, then when he returns, he will be younger than his brother on earth.
