Infinity is a terrifying concept. Blaise Pascal once said: “When I consider the short duration of my life, swallowed up in an eternity before and after, the little space I fill engulfed in the infinite immensity of spaces whereof I know nothing, and which know nothing of me, I am terrified. The eternal silence of these infinite spaces frightens me.” On some level, we are incapable of conceptualising what it means for an infinite universe to exist; if the universe is infinitely large, we are by comparison infinitely small.
