Melot Adrian (Adrian Melott), professor of physics and astronomy at the University of Kansas, and Brian Thomas (Brian Thomas) from Washburn University (both – the U.S.) have proposed a new explanation for the mysterious “event Charlemagne” – named after the simultaneous him victory for Charles 774-775’s clashes with the Lombards.

Recall: the phenomenon was discovered in 2012, was in an abnormal surge in the concentration of radioactive carbon-14 in tree rings of the era. Its discoverers explained bursts of cosmic rays. “They concluded that [if it was caused by a luminary, then] the sun had to be attributed to a thousand times more powerful radiation than observed during [the largest in the known history of mankind] geomagnetic storm in 1859 – says Adrian Melot. – We just viewed carefully these erroneous calculations and found that the outbreak was only 10-20 times stronger than … in 1859. ”

Indeed, the assumption of a solar flare, a thousand times more powerful than the strongest out of all known, it is impossible to accept. But the 10-20-fold deviation look reasonable and preferable to a supernova explosion – the benefit of the eastern astronomers at this time have already fixed supernovae, but in the years 774-775 noticed nothing.

It adds Mr. Melot, data space telescope “Kepler” show that Sun-like stars are peculiar to periodic outbreaks with a capacity well above the standard. This is the flash and explains the sharp increase in radioactivity in 774-775 years, scientists believe. In addition, he said, the alternative is close exploding supernova should be excluded for other reasons. To give it a burst of growth in carbon-14, the supernova was to erupt within 100 light years. However, a similar phenomenon in the afternoon was obliged to look brighter than the full moon at night – and so for months. It is impossible to imagine how it could go unnoticed. In addition, the remains of such a supernova would still be visible, which is within 100 light years is observed.

It is extremely unlikely scientist believes and gamma-ray bursts from distant supernova – an event when two opposite points of the supernova explosion erupt dense gamma beams that span vast distances. Yes, they can “get” to some of the planet for many thousands of light years, for distributed relatively coherent. But even at such a distance from the solar system, said Mr. Melot, this happens every 15-20 million years – so, 1250 years ago, the probability of this phenomenon was incomparably lower than superoutburst on the Sun.

By the way, the investigator reasonably believes that the event is not the last. It is, according to “Kepler”, about once in a thousand years or so, so wait. It is true that we will survive the cataclysm with much bólshimi losses than the Carolingian state and his contemporaries. The then humans could get an easy rise in the incidence of skin cancer (due to the destruction of a significant amount of ozone) and falling yields. And here we are … But what’s there, in 1859, around the world refused to even wire (telegraph) connection. Imagine how it will affect the wireless communication? .. An event that is 10-20 times more powerful than a solar flare time of Charlemagne, would cause in steel pipes and metal conduct electricity the more power than they are long. Oil and gas pipelines, transformers, large and small power – all this can easily be damaged. So electricity can disappear – and not for two hours, for quickly replace all the transformers did not work. And it does not mention such a small, but suddenly found themselves under high voltage rail and mass death of most electronic devices. In short, a successful December!
