# Infinity

(Redirected from Infinite)

Infinity, also written $\infty$, is the name for a group of ideas about things which never end. The term is from a Latin word meaning "without end". Infinity goes on forever, so sometimes space, numbers, and other things are said to be 'infinite', because they never come to a stop.

Infinity is really not an ordinary number, but it is sometimes used as one.

There are two kinds of infinity: potential infinity and actual infinity. Potential infinity is a process that never stops. For example, adding 10 to a number. No matter how many times 10 is added, 10 more can still be added. Actual infinity is a more abstract idea. For example, there are infinitely many numbers as it is impossible to write them all down.

Infinity has various properties that are not normally found in numbers:

## Infinity in Mathematics

Mathematicians use different kinds of infinity. For example, uncountable sets are bigger than countable sets. Both kinds of set are infinitely big. We can write infinity as reference. Example: 100 is like infinity for 0.00001 if the first term is started from 0.00001. Likewise 10000000000000000000000000 is like infinity for 10 if the first term is started from 10.
