For all of the many ways Hollywood movies have devised for humanity to deflect deadly asteroids, they've never considered paintballs.
But scientists have.
According to new research, a hypothetical asteroid heading for Earth could be deflected with little more than two, big and well-aimed, paintballs.
By coating an asteroid in paint, the idea is that the rock would become more reflective - and be diverted by photons from the Sun bouncing off its surface.
Sung Wook Paek came up with the idea, and this weekend it won a competition sponsored by the United Nations' Space Generation Advisory Council, named the 'Move an Asteroid Technical Paper Competition'.
No, there are no plans to weaponise the space shuttle with a giant paintball gun. Rest unassured: if a deadly rock were discovered to be hurtling towards us, we're just as defenseless as ever. But it's nice to know someone, somewhere, is working on it.
Take a look at the video of the theory above.
