The new study showed a supernova 2.6 million years ago, influenced by climate change and caused mass deaths of ocean dioxide, including large oceanic animals.
Professor of Physics and Astronomy at the University of Kansas, Adrian Melot, told Xinhua on Sunday that there were one or more supernovaes with about 150 light stars on earth.
Supernova is the star of the end of life. It can briefly review all galaxies and can generate more energy than all the days of your life. It is also the primary source of heavy elements in the world.
According to NASA, the supernova is the biggest blast seen by humans.
The author of the new article in astrobiology, Melot, presented the three types of seabed, including the iron-60 isotope, the proof of the time and distance of supernova.
Iron Iron-60 had no other way to get to Earth, but supernova.
Melot's team has been doing research for about 15 years.
Supernovative energy that dissolves the Earth's iron-60 layer has also led to the so-called muon particles that have spread to the Earth, and especially to large animals, especially malignant tumors and mutations.
"We estimate that the incidence of oncologic diseases increases to 50 per cent for the size of a human being, so the more you are, the worse the dose for the elephant or whale rises," he said.
2.6 million A year ago, the supernova could be due to the disappearance of the sea megafuneral on the Pleiß-Plastechen border, which accounts for 36 per cent of the descendants.
"High energy muon can deepen deeper in the oceans, which is the most important agent of biological damage, and deeper," the statement said.
"It has been 2.6 million years old from Megaldo," says Meloth. "We can presume that we can do something with the muons, and the larger the creature, the greater the radiation."
