New Delhi : When the earth was formed, it was a hot fireball. After a few crores of years, a thick sheet of snow was spread on it. That is, the Ice Age. Then there were no countries in the world. Humans didn’t exist. There was only snow everywhere. This was the time about 500 million years ago. This was centuries before the time of dinosaurs. Do you know that the Ice age has come to Earth many times. But what was the biggest reason behind the ice age? Scientists have uncovered this mystery.

Asteroids were the reason behind the ancient ice age on Earth. Scientists have discovered that there was a collision between two giant asteroids. Due to which the era of ice age had started on the earth. This ice age was for millions of years. The question arises that if there was a heat in the collision of asteroids, then how the snow had accumulated for millions of years.

This study has been published in a journal called Science Advances. It has been told that after the heat generated by the collision, a huge amount of dust accumulated on the earth. However, this was a very small part of the dust caused by the asteroids in space.

46.6 million years ago, an asteroid that came from between Mars and the planet Jupiter collided with another asteroid near the earth and broke. This caused a lot of dust and heat on the earth. Scientist Philip Heck, who did this study, said that more than 40 tons of dust comes from the space every year. But at that time, due to this collision on earth, 4 lakh tons of dust had come.

In this same quantity, this dust kept coming on the earth for 20 lakh years. Dust was so much in quantity that if it is filled with trucks, then it will take about 100 crore trucks. Hot dust came to the earth and got colder. Due to this, the climate of the earth started getting cold. When the earth started getting cold, ice started to freeze all over.

Philip Heck said that we have found some micro meteorites in Antarctica which came to Earth due to the rupture of 46.6 million years old asteroids. When its age was checked using carbon dating, the whole matter was understood. For two million years, cold dust fell on the earth.

The creation of life started with the freezing of ice on the cold earth. Different types of small creatures began to flourish in different parts of the earth because the temperature was different everywhere. Therefore, according to the weather, organisms began to flourish. But the ice age remained for millions of years. Therefore, it is called the Ancient Ice Age.

Earth’s temperature was slowly changing. It was favorable for the origin of life. If the temperature and climate suddenly change, then there is no question of life existing. Like when a meteorite collapsed, the entire species of dinosaur was eradicated from the earth.
