The news channels were filled up with the news that asteroids can destroy the earth soon but then the news came that scientists have told that earth is safe and no asteroid can harm us. First, they thought they are not a threat anymore but now the things started to seem difficult for them. Those asteroids are possessing the capability to damage the earth. NASA has first accounted for this report and now scientists are working in order to destroy the space rocks.

Some asteroids are coming to the trajectory towards our mother planet earth and it is seeming that it could create great damage to mankind. Charles El Mir said, “Asteroids are stronger than we used to think and require more energy to be completely shattered” The new study has been conducted by the John Hopkins University which gave the results by the computer modeling and analysis of rock fracture. Previously the scientists thought that the asteroid rocks will be destroyed easily by their plan but now with new finding, it seems tough.

Charles El Mir said, “We used to believe that the larger the object, the more easily it would break because bigger objects are more likely to have flaws. He added, “Our findings, however, show that asteroids are stronger than we used to think and require more energy to be completely shattered.”

El-Mir said: ”It may sound like science fiction but a great deal of research considers asteroid collisions. “For example, if there’s an asteroid coming at the earth, are we better off breaking it into small pieces, or nudging it to go a different direction? “And if the latter, how much force should we hit it with to move it away without causing it to break? These are actual questions under consideration.”

K.T. Ramesh, director of the Hopkins Extreme Materials Institute, added: “We are impacted fairly often by small asteroids, such as in the Chelyabinsk event a few years ago. He added, “It is only a matter of time before these questions go from being academic to defining our response to a major threat.

“We need to have a good idea of what we should do when that time comes—and scientific efforts like this one are critical to helping us make those decisions.”
