Why science/math matters...

A new and surprising rate at which an asteroid collides with Earth has been calculated by the B612 Foundation—a private group dedicated to defending the Earth against such catastrophes.

In spite of lower estimations calculated by other scientists, the B612 Foundation has collected data suggesting that the Earth is capable of being hit by an asteroid once a century, a rate previously thought to be once every 3,000 years. Physicist and former space shuttle astronaut Ed Lu, who is CEO of B612, explains what his data shows.

“There are people who say, ‘Oh, once every million years we have something we have to worry about.’ That couldn’t be more wrong,” says Lu.

“Eventually you’re going to get hit, because it’s just a matter of time,” he adds.

Evidence which supports this prediction was collected and made accessible by Peter Brown of the University of Western Ontario. The data gathered was administered by a network of sensors that detect nuclear explosions. Picking up sound waves, the sensors have detected 26 asteroid explosions since 2001. Some of these collisions occurred during 2009 and 2013, one off the coast of Indonesia and the other over Russia, respectively.
