Are we alone? Sir Martin explores the possibility that life exists on planets beyond our own. He unveils an unsettling scientific debate that has startling consequences for us Earthlings. Do you believe in aliens?

Why are we here? Everything you thought you knew about the universe is wrong. It's made of atoms, right? Wrong. Atoms only account for a measly 15% of everything that exists. The mass of the universe consists of something so mysterious and elusive that it has been dubbed 'dark matter'.

Are we real? There is a fundamental chasm in our understanding of ourselves, the universe, and everything.

To solve this, Sir Martin takes us on a mind-boggling journey through multiple universes to post-biological life.

On the way we learn of the disturbing possibility that we could be the product of someone else's experiment.
