The Megalodon is the largest shark in history, reaching a length of about 20 meters and extinct about 2.6 million years ago.

Contrary to horror movies, because of their titanic size, megalodons were probably very slow predators and looked more like whale sharks than deadly white sharks attacked.

The reason for the extinction of megalodons is not precisely established. According to one version, global climate change is to blame, because of which the oceans have become colder.

According to another version, which has become more popular in recent years, megalodons simply could not stand competition with new smaller and faster carnivorous species. Especially with toothed whales, the ancestors of killer whales that hunted in packs and had more developed brains.

At the end of November 2018, a scientific work was published in the journal Astrobiology, which indicated the connection between the extinction of the megalodon and many other ancient animal species and a supernova explosion that occurred at the same time interval 2.6 million years ago.

This supernova is located at a great distance of 150 light years from Earth, but after its outburst, the Earth would still be bombarded by cosmic particles - muons.

These are elementary particles, similar to electrons, but heavier. Muons pass through us all the time and account for about one fifth of the radiation dose we receive. And when there are many of them, it damages living cells.

While searching for evidence of his theory, Mellot found deposits of iron-60 isotopes on the seabed. And even at a depth of a kilometer. Iron-60 isotopes appear only during supernova explosions, and if they are found somewhere in large quantities, then a supernova has exploded somewhere.

Iron-60 is a radioactive substance that enters our planet with cosmic rays and has a half-life of about 2.6 million years. This means that any iron-60 that could have formed on Earth at an earlier period would have decayed long ago.
