Quantum mechanics may be counter-intuitive, but it's one of the most successful theories in the history of science, while also launching the technological advances at the heart of modern life, like computers and cell phones.

Brian Greene looks at the theory of multiple universes. Alternate realities where we could exist with different lives, loves and careers. In others, reality may be so radically different from ours as to be unrecognisable.
