Mass extinctions cause the destruction of all life on the planet.
Scientists have found that cataclysms of a global nature occur on Earth every 27 million years. Perhaps now the next cycle has begun and soon the whole mankind will come to an end.
Over the past 500 million years, there were five major disasters on the planet. The most famous event is the extinction of the dinosaurs 66 million years ago.
At the same time, over the past 300 million years, a lot of animals and birds have disappeared.
Specialists have conducted studies on the extinction of living creatures on land and in water. They found that mass extinctions occur every 26-27 million years. Typically, this happens as a result of a huge asteroid impact or the eruption of a large volcano.
This time, our galaxy itself can provoke the extinction. Michael Rampino said that the number of large-sized asteroids has recently increased. Also, the pulses resulting from the internal activity of the Earth, provoking the emergence of basaltic volcanism, have become much stronger.
In addition, every 30 million years or so, the Earth and other planets in the solar system pass through the middle plane of the Milky Way, where there are a huge number of comets. They can easily fall on Earth and destroy all life on it.
