“An epic battle between paintballs
and a giant asteroid could one day save the Earth from an apocalyptic space
rock impact.” Scientists believe that if an asteroid was going to crash
into the earth that if they shoot a cloud of paintballs into space, it would
nudge the asteroid off its path and the pale paint job resulting from the
splattered pellets would more than double the space rock's sunlight reflectivity.
More photons bouncing off the asteroid's surface would enhance solar radiation
pressure and bump it further off course. Then the earth would be saved.
