Studies show that supernova can cause the disappearance of Megalodon

The new research showed a supernova that took place 2.6 million years ago, maybe touched by climate change and caused massive extinction of large animals from the ocean, including Megalodon.

In an interview with Xinhua on Sunday, Adrian Mellot, a professor of physics and astronomy at the University of Kansas, said that perhaps one or more supernova series had taken place, about 150 light-years from Earth.

Supernova is the explosion of a star that has reached the end of its life. It could briefly overcome the entire galaxy and radiate more energy from the sun throughout its lifetime. It is also the primary source of heavy elements in the universe.

According to NASA, supernova is the biggest explosion people have ever seen.

Melt, the lead author of the paper published in Astrobiology, says that three seabed species, including iron-60 isotopes, provided evidence of the time and distance of the supernovae.

There was no other way for Iron 60 to reach Earth, but from supernova, he said.

The Melot team explores this for about 15 years.

The supernova's energy, which spreads the iron-60 layers around the world, also caused penetration of particles called muions to quench the Earth, causing cancer and mutations, especially of larger animals.

"We estimate that the cancer rate will increase by about 50 percent for something that is the size of a person. The bigger the worse it is, the elderly radiation goes up," he said.

Supernova 2.6 million years ago could be linked to the extermination of the marine megafauna at the border of Pliocene-Pleistocene, where 36 percent of the genera are missing, according to the survey.

"High energy muons can reach deeper in the oceans as a more relevant agent of biological damage, as the depth increases," the paper said.

"One of the disappearances that took place over 2.6 million years ago was Megalodon," Melot said. "We can speculate that it can have a relationship with the muons. In fact, the larger the creature, the greater the increase in radiation."
