Earth has been hit by a gamma ray explosion

A gamma ray explosion, the strongest form in the universe, may have hit Earth in the 8th century.

In 2012, researchers found evidence that our planet was caught by a mysterious radiation burst in the Middle Ages, but at that time experts did not agree on the cause. after this phenomenon.

Traces of this strange event were discovered by Japanese astrophysicist Fusa Miyake, after identifying the carbon-14 spike, isotope associated with high-energy radiation, in the tree rings of ancient cedar.

The time of the trunk of radiation was contaminated in 774 or 775, according to the Monthly Notices of the Royal Astronomical Society.

Space scientists in turn gave enough hypotheses, but none of them were suitable, and no supernova explosion occurred at the time.

Recently, scientists from the University of Jena (Germany) have given an explanation, it may be the result of the terrible collision between two black holes in the process of combining, and in a short time they expelled an extremely high amount of gamma rays.

In addition, the event in 774 or 775 can only take place at least 3,000 light years away, otherwise the Earth has been baked.
