Astronomers have suggested that gamma-ray bursts are able to return in time back. The results of his study of astrophysics published in The Astrophysical Journal.
Gamma-ray bursts are powerful cosmic emissions energy in the form of explosions that are often observed in distant galaxies in the hard range of the electromagnetic spectrum. To scientists it is known that particles can travel faster than light in a certain environment that has a characteristic blue glow. Researchers conducted an experiment to simulate this situation.
Scientists also said that they were able to find out that in the expanding gamma-ray flow, the shock wave can behave differently. In this case, there is an interaction with others. space. The result of this phenomenon is radiation at movement above the speed of light, and thermally synchrotron or Compton radiation at a slower speed Sveta.
When charged particles at a speed close to the speed of light get into the liquid, they begin to move faster than Cherenkov radiation. Thanks to this, theoretically, to be in two places at the same time. Study in this the direction was held at Michigan State University (USA).
