To amplify a bit -- if we pick a real number (say in (0,1)) the odds we hit it with a randomly thrown dart is exactly zero. So it reasonable to assume that what goes for darts goes for light rays too. That randomly chosen real is "invisible". The real number line is almost, or completely, entirely invisible. Is the rational number line likewise?

What do we really see then?

Cheers,
Joe N
