Summary

To Infinity and Beyond takes viewers on a mind-bending journey through a concept that throws up more riddles the closer we get to grasping it.

As young children, we learn to count. Once we know how, it seems as if there would be nothing to stop us counting forever.

For most people, this is our first and most extensive encounter with infinity. There’s something about it that captures the imagination, the notion of something going on and on beyond our comprehension and never quite reached.

But, while infinity might seem like an perfectly innocent idea, keep counting and it gets more complicated. 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.

If the universe goes on forever, the consequences are even more bizarre. The programme shows that, if you follow the logical conclusion, then in an infinite universe, there are infinitely many copies of the Earth and infinitely many copies of you.

This is the story of infinity.
