Part of the new Ladybird Expert series, The Big Bang is an accessible, authoritative, and entertaining introduction to the greatest discovery in the history of science: that the universe has not existed forever but was born. There was a day without a yesterday. Written by award-winning writer and former astrophysicist Marcus Chown, The Big Bang details how 13.82 billion years ago all matter, energy, space - and even time - erupted into being in a titanic fireball. This mind-bending book addresses the big questions: What was the Big Bang? What drove the Big bang? And what happened before the big bang? The evidence for the Big Bang, it turns out, is all around us... Written by the leading lights and most outstanding communicators in their fields, the Ladybird Expert books provide clear, accessible and authoritative introductions to subjects drawn from science, history and culture. For an adult readership, the Ladybird Expert series is produced in the same iconic small hardback format pioneered by the original Ladybirds. Each beautifully illustrated book features the first new illustrations produced in the original Ladybird style for nearly forty years.
