NASA reveals space weapon to stop asteroids but what happens if it fails?
NASA unveiled a space weapon that could prevent an apocalyptic land of asteroids hitting hidden but if the plan fails, Armageddon could be more real than we think.
Even theoretical physicist Stephen Hawking says it is only a matter of time until Earth, as we know, can be destroyed by an asteroid.
“This is not science fiction. It is guaranteed by the laws of physics and probability,” Professor Hawking said in a speech at the Starmus science festival this year.
He affirmed that if the human race did not begin to leave the Earth to another planet, that ran the risk of “annihilated”.
“Reclining in space will completely change the future of mankind. One can also determine if we have a future,” said Professor Hawking.
Science Daily reports Professor Alan Fitzsimmons astrophysicist also warns if an asteroid hits the earth, could destroy an entire city.
“More than 1800 potentially dangerous objects have been discovered so far, but there are many more waiting to find,” he said.
“Astronomers find the asteroids close to Earth every day and most are harmless. However, it is still possible that the next Tunguska surprise us, and although we are much better at finding the larger asteroids, it does us no good if We are not willing to do something about it.
The last major asteroid to collide with Earth was in 1908. The asteroid or comet of Tunguska exploded in a zone of forest in Siberia, flattening 2,000 square kilometers.
According to the source book of the Tunguska event, it was the largest impact event on Earth, with the estimated comet size between 60 and 190 meters wide. It is believed that the explosion would hit more than 80 million trees and have registered a magnitude of 5.0 or higher on the Richter scale.
Research on the event by the Italian researcher Giuseppe Longo, physicist at the University of Bologna, found that the explosion was able to destroy a city.
This year’s research from the University of Southampton has revealed that there would be winds and tsunami killers if an apocalyptic asteroid hits the ground.
Researchers say the winds caused by the asteroid could be more damaging than the asteroid itself and could eliminate millions.
The university said winds and shockwaves account for 60 percent of deaths if an asteroid struck Earth.
The researchers examined seven different asteroid impacts of the end of the world, such as heat, pressure, shockwaves, debris, tsunamis, wind gusts, seismic quake and crater, and shockwaves and gusts of wind were the More deadly.
“Shock waves from a peak of atmospheric pressure and can rupture internal organs, while gusts of wind have enough energy to make the human body work and flatten the forests,” the research said.
The investigation examined a number of different scenarios if an asteroid hit Berlin and London. If an asteroid was 50 meters wide and a blast of air traveled 20 kilometers and hit the two cities, it kills 1.2 million people in Berlin and more than 2.8 million people in London.
