It happened once can happen again and we can not do anything to survive. NASA scientists have concluded that mankind is prepared and would be for several decades, in case of collision of the Earth from asteroids.
The alarm was issued by Joseph Nuth, the American Space Agency astronomer at the American Geophysical Union meeting last week.
"We are totally helpless and adrift if we are stricken by asteroids the size of those believed to have become extinct dinosaurs from Earth's surface," says Nuth.
It is believed that stroke occurred 50 to 60 million years ago, and this interval increases further the risk that our planet is attacked again.
Joseph Nuth says the signals are already sent. He mentions here comet that 'shorn' planet in 1996 and an asteroid in 2014. In the second case we were lucky.
"In 2014 the asteroid passed the Earth-Mars distance. It seems far away, but if we were unlucky and it was in collision trajectory with us, will not be able to do anything, "says Nuth.
In the community of scientists widely believed that the dinosaurs became extinct 66 million years ago after the collision of an asteroid with the Earth by 10 kilometers wide, the crash of his thought is the Gulf of Mexico today.
