Physics again confirmed the theory of relativity

Physicists from the national accelerator laboratory named Fermi (USA) have not been able during the experiment to refute one of the main provisions of the theory of relativity - the principle of Lorentz invariance. Research findings published in Physical Review Letters.

The principle of Lorentz invariance postulated that all physical laws apply equally regardless of the position and orientation of the laboratory in space and time. One consequence of the Lorentz-invariance, in particular, the continuity of physical processes when turning the system on an arbitrary angle. So, turn the laboratory along with the Earth's surface during the daily rotation of the planet should not influence the process. And day and night, the result of the experiment should be the same.

To check the situation of physics using neutrinos - particles with a very high pronikayuschey ability. Neutrino received irradiation carbon target for the accelerator of charged particles, channeled through the layer of soil located at a few hundred meters detector, which recorded the number of particles and energy. In the accumulation of such data to physicists trying to find a correlation result from the time of day. Althea not disclosed.

It turned out that the beam behaves the same way in any position in space and all directions are the same for him: the principle of invariance once again confirmed its performance.

Equity lines in the space it seems obvious from everyday experience and all the earlier experiments, but physicists microworld that experience is not an argument. There are several theories, which highlighted the direction there, and that violations of Lorentz invariance played an important role in shaping the universe. The results of this experiment, if not refute these theories, at least impose significant restrictions on them.
