Imagine if The Hitchhiker's Guide to the Galaxy was a real handbook . Internationally renowned physicist Christophe Galfard takes us on a wonder-filled journey through the past, present and future of the universe - all from the comfort of your sofa. The Universe in Your Hand takes you on a journey through some of the most profound and amazing facts about the universe: Quantum Mechanics, General Relativity, String Theory and Parallel Realities, with the promise that you'll only see one equation - the fabled E = mc2. Christophe Galfard, who worked as Stephen Hawking's research graduate, transports us to the surface of our dying sun, flies us to distant galaxies and puts us into the deathly grip of a black hole. As he explains the mysteries of physics he uses a language that will leave no reader behind.Written from the cutting edge of the known universe, The Universe in Your Hand will allow readers, for the first time, to really understand the mind-bending truths that underpin modern science, and along the way looks deep into questions about our place within the universe, the beginning of time and where we fit into the future of humanity.
