The International Team of Astrophysicists and the National University of Nuclear Research "MIFI" ( NINU MIFI) gave a theory that explains that the observed experiment, abnormally high content of antimatter (positron and antiprotone) in cosmic rays is the result of a supernova explosion near the system solar.

In the series of experiments, anomalies in cosmic ray spectra have been discovered in recent years. In particular, a high flux of antimatter (positron and antiprotone), a change in the relationship between the proton and helium flux, depending on their energy (which, in the case of a only source of air, should not exist), was found. In addition, anomalies in the anisotropy (inequality of average properties) of cosmic rays were found.

Scientists have proposed a number of models that individually explain some of these anomalies. The international team of astrophysicists from Russia, France and Switzerland has developed a theory that explains all cosmic ray anomalies recently discovered.

According to a new theory developed by the National University of Nuclear Research of MIFI (NINU MIFI Moscow, Russia) in Trondheim (Norway), the Department of Astronomy of the University of Geneva, l & rsquo; Didro University (Paris, France) and the Observatory of the Sorbonne (Paris, France), one of the main reasons for the anomalies observed is the explosion of the supernova

L & # 39; One of the authors of the theory, published in the journal Fizikal Rice, is Professor Nin MIFI, Dmitry Semikoz: "The explosion of the supernova has occurred about 2 to 3 million years ago. 39 years at about 220-450 light years. (1965 to 006) According to this scientist, recent exploration of the Earth's crust at the bottom of the ocean and moon's soil has unambiguously shown that about two million people lived in the world . year proximity The temporal indicator of this cosmic event is the content of the iron isotope Fe-60 that appears only in the supernova explosion

"If the events described are the Earth is waiting for global climate change and a significant increase in radiation. When the supernova exploded ten times further, the consequences for life on our planet could be catastrophic, "said the professor. 19659010] "Depending on the distance of the supernova, the Earth would have been completely or completely completely dead all the time". he said

Fortunately, such an event happens very rarely. Supernovas, at a distance of several hundred pieces of land, explode once in a few million years, while they are really dangerous for life from the supernova explosion to a dozen or so billion years.

Dmitry Semikoz and his American and European colleagues, showed that the "firing" of the Earth by cosmic rays after the explosion of a supernova star at a distance of 300-600 light-years before about 3.2 to 8.7 million years could disrupt the "biological clock" of animals and accelerate the biological evolution on our planet due to a sudden jump in the amount of mutations due to the increase of the level of radiation.
