By
our third year, most of us will have learned to count. Once we know
how, it seems as if there would be nothing to stop us counting forever.
But, while infinity might seem like an perfectly innocent idea, keep
counting and you enter a paradoxical world where nothing is as it seems.
Mathematicians
have discovered there are infinitely many infinities, each one
infinitely bigger than the last. And if the universe goes on forever,
the consequences are even more bizarre. In an infinite universe, there
are infinitely many copies of the Earth and infinitely many copies of
you. Older than time, bigger than the universe and stranger than
fiction. This is the story of infinity.
