For those unfamiliar with this existential horror, the Grandfather Paradox is a thought experiment posited by the inimitable René Descartes (not the cheese). It goes like this:
Sounds simple enough, doesn't it? You'd think it's just a matter of time-traveling back, popping off your unsuspecting progenitor, and then returning to the present, problem averted. But no. It's not so simple. You see, by killing your grandfather, you'd never have been born. Never had children of your own. Never, therefore, killed your grandfather.
And there you are, stuck in an infinite loop of non-being. A temporal paradox so elegant, it'll make your head spin.
