Large rocks fall from space. Dinosaurs are extinct this way!

A recent study found that the rate of mbadive rock falls from space had become the usual weakness, calling at the same time not to worry.

Over the past 290 million years, asteroids have fallen to Earth more than twice as much as 700 million years ago.

"There is nothing to worry about," he said. "On average, asteroids still hit the Earth every two or three million years, even with a rate of increased collision. "

Experts said the biggest known risk was an asteroid 1.3 km wide with a 99.988% probability of not touching the Earth while it was very close in 861 years.

Most scientists believe that dinosaurs and many other breeds have disappeared as a result of the crash of a huge space rock in Central America about 65 million years ago.

"These events are so rare and so distant that I do not worry about them," said Sarah Mazroui, scientist in planetary sciences at the University of Toronto, the principal author of the study, "it's just a game of possibilities".
