German mathematician David Hilbert proposed the infinite hotel paradox as a way to illustrate the confounding properties of infinity. It was a way to expound on the theories of Georg Cantor, who proved there were different kinds and sizes of infinities in the late 1800s. Hilbert proposed different mathematical strategies for clearing out rooms in the infinitely booked, infinite hotel to accommodate new guests-even if they arrived in infinite numbers.
