It has recently been known that the earth has to face such troubles again and again. In 2012, Japanese astrophysicist Fusa Miyake (Nagoya University) discovered that the rings of some trees in the Japanese cedar (the national tree of Japan – also known as “sugi”) contain exceptionally high concentrations of the radioactive carbon isotope C-14.
For example, Miyake found that rings from the year 774 had significantly increased concentrations of C-14. He concluded that it could only be explained by a shower of cosmic rays that fell on Earth at that time.
Obviously, the dose of radiation at that time was too small to kill humans and animals. The situation was similar with another cosmic shower, created by Miyake in the year 993 based on the annual rings.
Meanwhile, researchers have been able to identify further “Miyake events”. 7176 BC is considered definite. 5410 BC 5259 BC and 663 B.C. Chr.
Scientists see star explosions or strong sunquakes as the main cause of repeated cosmic radiation from space to Earth.
Measurements in Antarctic ice, in which cosmic rays caused increased concentrations of radioactive beryllium-10 in the years in question, indicate that at least the Miyake events 774 and 993 are of solar origin.
Of course: Miyake’s events so far cannot predict when the next cosmic shower will hit Earth – tomorrow or in a thousand years? But even if the next rain is not as fatal to humans and animals as the previous rain, civilization will still be in grave danger.
All satellites, computers and the entire electronic infrastructure on Earth would fail – with unpredictable consequences. A cosmic shower with high concentrations of radiation has not been noted. In such a situation, all life on earth could be destroyed in a jiffy.
