"If I didn't need to do anything, would I? Would I oscillate in two or three dimensions? Would I summon a beholder and change chirality for "him"? A massless particle passes through the void with no resistance. Ask what it means to pass through the void. Ask how it differs from not passing."
(an object or a system is chiral if it is not identical to its mirror image,
that is, it cannot be superposed onto it.)
