A Journey Through Space, Time and Beyond

Imagine if The Hitchhiker's Guide to the Galaxy were a real, practical book about the mysteries of the universe...

The Universe In Your Hand takes us on a wonder-filled journey to the surface of our dying Sun, shrinks us to the size of an atom and puts us in the deathly grip of distant Black Holes. Along the way you might come to understand, really understand, the mind-bending science that underpins modern life, from Quantum Mechanics to Einstein's theory of General Relativity.

Through brilliant storytelling and humour rather than graphs and equations, internationally renowned astrophysicist Christophe Galfard has written an instant classic that brings the astonishing beauty of the universe to life - and takes us deep into questions about the beginning of time and the future of humanity.

"Galfard dispenses with mathematical formulas in this foray into modern physics, making a lively imagination the only portal necessary for general readers hungry for the intellectual excitement of astral and atomic exploration. In a series of mind-stretching thought experiments readers plunge into the hydrogen atom in a water molecule, there to contemplate the quantum fields that sustain all matter, then shoot out beyond supernovas to ponder the strangely opaque boundary of space-time... these probes into the universe will thrill readers but rarely perplex them... Galfard leaves exhilarated readers eager to share in the forthcoming discoveries."

—Booklist, Starred Review

"Entertaining and comprehensive... The deft and dazzling imagery makes difficult concepts accessible, streamlining the progression through topics and fulfilling Galfard's promise to 'not leave any readers behind.'... Readers looking to expand their knowledge of physics and cosmology will find everything they need here."

—Publishers Weekly, Starred Review

"How can we ever hope to fully grasp the infinite complexities of space and time, or even the very nature of reality itself? Thankfully, Christophe Galfard shows us the way, through a well-written and thoroughly approachable journey through what we know of modern astronomy and physics. Part personal conversation, part travelogue, and part science primer for the non-scientist, The Universe in Your Hand is a delightful and highly educational read."

—Jim Bell, author of The Interstellar Age and Postcards from Mars
