About 13,000 years ago, the planet was exposed to a cold wave of climate that scientists could not include in any of the ice ages. To explain the existence of that period, some scientists assumed that what happened was not related to an event that had arisen on Earth, The sky.
In a new study published in the journal Nature Reports, an international research team announced that the Earth had been hit by a very strong 13,000 years ago from a comet, which was divided into several parts that were distributed in different parts of the planet.
Great event
The research team, led by Chilean paleontologist Mario Pino, has for several years been studying a range of rock layers that formed in the Pelaco Pago region of southern Chile, containing chromium-rich rock pellets that can only be formed in very hot temperatures , Which led them to imagine that this happened only in the case of the collision of a monster with a heavenly crime.
According to the new study, this collision caused a large initial explosion that destroyed life in its surroundings, ignited forest fires that lasted for years, and clearly reduced the presence of humans in these areas for many years, and changed the nature of animals that existed after the great event .
To reach those results, the researchers used pollen and coal schemes, which examine the components of deep soil layers next to rivers and lakes, thus giving an impression of the living organisms that lived there.
The giant that filled the ground
On the other hand, the new paper supports a precedent issued several years ago by UC Santa Barbara University which, in a similar way, revealed a 31-kilometer shock crater beneath Greenland's snow, which researchers thought was also part of the same comet Who hit the ground in that period.
According to the new study, this collision in various parts of the planet (the far north and the far south) caused successive environmental and climatic changes that eventually led to a sudden drop in temperature to pass the Earth by the so-called "little doracic" about 13,000 years ago.
The researchers hope the new study will help to understand the disastrous period of Earth's history better, which in turn may help to understand the future of the planet with this kind of danger from the sky.
