An MIT student has put forward an interesting theory: paintballs could deflect an asteroid's path enough to avert a collision with Earth. As demonstrated in the video below, a pair of perfectly-timed white paintball rounds should be enough to knock an asteroid off its current trajectory, but the really clever bit happens after. By coating the asteroid's surface in white paint its albedo (reflectivity) would increase. The highly-reflective asteroid would then be taken further off course by the pr...
