NASA is at it again, bringing back rocks from space, trying to figure out where we (and Earth) all came from. About a cup landed via parachute in the desert in the US. They also say there’s a 1/2700 chance that we’d get hit by this half-kilometre rock sometime in 2182. When I say “we”, that doesn’t include you or me.
By that time we’ll have lasers and space-flying cars and death-ray pistols to help us out, I think. Or not.
