Infinity is a concept that has fascinated mathematicians and philosophers for centuries.

There are different types of infinity, such as countable and uncountable infinity.

Georg Cantor was a mathematician who is famous for developing the theory of infinity in the late 19th century.

One of Cantor's most famous contributions was his proof that there are more real numbers than there are natural numbers.

The concept of infinity has surprising and counterintuitive properties, such as the fact that there are different sizes of infinity.

The continuum hypothesis, which Cantor formulated, asks whether there is a set of numbers between the size of the natural numbers and the size of the real numbers.

The continuum hypothesis was shown to be independent of the standard axioms of set theory, meaning that it cannot be proved or disproved using those axioms.

Infinity is also a central concept in calculus, which deals with limits and the behavior of functions as their inputs approach infinity.

The paradoxes of infinity, such as Hilbert's paradox of the Grand Hotel, demonstrate the strange and unexpected behavior of infinity.

The study of infinity has important applications in fields such as physics, where it is used to describe the behavior of the universe on both the largest and smallest scales.
