Part-history of the cosmos, part-intellectual adventure, this book travels from the Big Bang to the distant future via parallel worlds, across every possible scale - from the sub-atomic to the intergalactic - showing how mathematics provides the answers to our questions about the world. Where do we come from? What makes the universe the way it is?

A journey to explore the mysteries uncovered by cosmology and to discover the nature of reality from a science author well-known among his peers, and who has appeared on numerous documentaries, including BBC's "Horizon".
