The warning came "Horrible" On the language of several scholars in US Space Agency NASA reported, according to a British newspaper "The Star".
Experts from the Faculty of Mechanical Engineering revealed the Johns Hopkins University State Maryland In the United States for their warning in a recently released study, they said that targeting a celestial or space object by missiles was harder than expected.
Experts explained, who conducted a simulation experiment to target Asteroid With a nuclear missile, the initial impact would result in crushing or cracking the asteroid, but that would not prevent the direction of some parts of the asteroid and would not cut it to the ground.
The same academic expert, Charles El Mir, said that the study had been funded NASA I arrived with unexpected results, "he said." The question we asked at the beginning was how much energy we needed to destroy an asteroid by turning it into small pieces? "
He added, "We thought the large objects were easy to target and destroy, but our study found that the asteroids were stronger than expected and needed more energy to completely destroy them."
The results of the study contradict the prevailing view that a nuclear bomb can destroy big rocks And asteroids Which are heading towards the earth, as has appeared in some science fiction movies of the 90s of the last century, such as "Armageddon" and "Deep Impact".
Said El Mir, after simulating the bombardment of an asteroid in space "During the first stage of striking the asteroid with a nuclear missile, it will break into millions of pieces of rock, but some parts remain on what is, especially the core of the asteroid ".
He added that the second phase of the experiment had revealed an unexpected in the targeted asteroid, namely that the core of the asteroid did not break but remained consistent and restituted the force of gravity for shoot the broken pieces. "Explaining that the asteroid gets together after being destroyed in space.
The researchers discovered that breaking the core of the asteroid required much more energy than previously thought and that it could have an impact on the Earth comparable to previous theories of 39, a huge asteroid hitting the Earth, causing the extinction of the dinosaurs.

The warning was "terrifying" from a number of NASA scientists, according to the British newspaper "The Star".
Experts at the School of Mechanical Engineering at Johns Hopkins University, Maryland, have warned in a recent study that it was harder to target a rocket or celestial object with rockets.
The experts, who conducted a simulation experiment aimed at targeting an asteroid with a nuclear missile, said the initial impact would be to break it up or split it, but that would not prevent the parties from Asteroid to move it or cut it to the ground.
"The question we first asked was how much energy we needed to break an asteroid into small pieces," said Charles Elmer, an expert at the same university.
"We thought the big objects were easy to target and destroy, but our study found that the asteroids were stronger than expected and needed more energy to completely destroy them."
The results of the study contrast with the widely held belief that a nuclear bomb could destroy large rocks and asteroids heading towards Earth, as in some science fiction movies of the 1990s such as Armageddon and Deep Impact.
"In the first step of hitting the asteroid with a nuclear missile, it will crush on millions of pieces of rock, but some parts remain on what is particularly the core of the rocket. asteroid, "said El Mir after simulating an asteroid in space.
He added that the second phase of the experiment had revealed an unexpected thing in the target asteroid: the core of the asteroid was not breaking but remained consistent and restored the gravitational pulling force the broken pieces, "explaining that the asteroid was regrouping after the destruction in space.
The researchers discovered that breaking the core of the asteroid required much more energy than previously thought and that it could have an impact on the Earth comparable to previous theories of 39, a huge asteroid hitting the Earth, causing the extinction of the dinosaurs.
