On February 15th, 2013 a fireball fell down near a Russian city called Chelyabinsk, leaving nearly 1,500 injured and a lot of damage. Three years afterwards it is still unknown where it came from. Although more than 200 scientific studies have been published on this subject, none of them has come up with a satisfactory solution to this problem. It seems that the meteorite exploded when it was 20 kilometres over the ground and liberated an amount of energy that was 30 times as much as that of the Hiroshima atomic bomb. Many meteorite fragments were found after the explosion, including a 650 kilogram one, which landed on a lake. According to some experts, happenings like this may occur once every 10,000 years. What all the scientists agree on is the impossibility of predicting where and when the next fireball will fall down.

The important part is that it is IMPOSSIBLE to predict the next one. Rephrase so that word is easier to pick out.
