Is this the end for our planet ?

Earth is now more threatened by space rocks than ever, three times more than the time of dinosaurs 290 million years ago, according to astronomers.



The researchers also believe that cosmic collisions caused the extinction of dinosaurs 66 million years ago, when a particularly large meteorite landed in Mexico and formed a "Chicxulub" pit, which destroyed most of life on Earth.
Astronomers have devised a "sporadic time" simulation to understand the rate of cosmic events on the moon, and then apply it to the planet.

"Our research provides evidence of a dramatic change in the rate of asteroid effects on Earth and the Moon that occurred at the end of the Paleozoic era, which means that since then, the Earth has experienced a relatively high rate of effects," said Dr Sarah Mazroui of the University of Toronto. Asteroids, by 2.6 times higher than they were 290 million years ago. "

Previous research has claimed that most of the earth's crusts caused by meteorite collisions have been erased through the complex geological processes of the planet.

Using NASA's Lunar Exploration Equipment (LRO), an international team of researchers has created a comprehensive map of the effects and history of asteroids.

The researchers drew up a timetable for the effects of the moon, and calculated the rate of rock crash to soil, revealing that there was a relationship between the amount of large rocks near the pits as well as their age.

The date of the moon's bombing with asteroids was similar to Earth. While the cause of the rise in the collision rate is unknown, researchers expect it to be associated with large collisions that occurred more than 300 million years ago, in the main asteroid belt between Mars and Jupiter orbits.

The results challenge our previous understanding of Earth's history, which is marked by major extinctions and the rapid development of new species.
