The astroid shower on Earth is increasing!Due to various destructive explosions and gravitational processes in the universe the heavenly bodies like Earth are exposed to the shower of astroids which are small bodies of extra terrestrial rocks falling on the Earth surface continuously.
While entering the atmosphere due to air friction they burn and turn into ash and spread finely on Earth surface. In rare cases when their size is big they hit the Earth and have devastating effects.
I was reading a science study in which the scientist have discovered that the amount of astroids falling on Earth has increased about three times as compared to 300 million years ago.
There is nothing to fear seeing this long time but I was just wondering why this increase and what does it signify.
