George and his best friend Annie haven't had any space adventures for a while and they're missing the excitement. But not for long . . .
Seriously strange things start happening. Banks are handing out free money; supermarkets can't charge for their produce so people are getting free food; and aircraft are refusing to fly. It looks like the world's biggest and best computers have all been hacked.
George and Annie will travel further into space than ever before in order to find out who is behind it.
Unravelling the latest amazing breakthroughs in theoretical physics, Stephen Hawking guides the reader through the evolution of Einsteinian physics to a universe of ten dimensions and a so-called theory of everything.
In this revised edition, Stephen Hawking includes recent developments in the field of cosmology. Explaining his theories through a visual dimension, the book is designed to help the lay reader to understand abstract ideas, such as the "big bang", black holes, and particle physics.
