In the 19th century, Cantor discovered that infinities come in various sizes. In particular, he showed that the size (or cardinality) of the set of real numbers is strictly greater than the size of the set of natural numbers, even though both sets are infinite.

This discovery raised the question of whether there could be a size of infinity that is strictly between the size of the natural numbers and the size of the real numbers. The continuum hypothesis, written as CH, is the statement that there is no such infinite size. In this talk, we will explore these ideas in more detail and consider how mathematicians have tried to figure out whether CH is true or not.
