The Universe In Your Pocket takes the reader on a journey through space and time using ten of the most game-changing and perspective-shifting maps ever created - each representing a major scientific advance and a startling new way of thinking about the universe. From the celestial maps of the ancients to a cutting-edge visualisation of the shape of the entire universe, we journey through its magnetic fields, along the fluctuating rivers of the solar winds to gravitational oases known as Lagrange points and the surface of Mars, through Black Holes and the enigma of Dark Energy, all the way to the very edges of the cosmos. Each chapter describes the theoretical leaps and feats of exploration that went into the creation of each map, the aspect of the universe it lays bare as well as the mysteries it reveals. Written by an astrophysicist at the forefront of this adventure, The Universe In Your Pocket is a small book about human curiosity on the grandest scale. Like the maps themselves, it offers a way to grasp the unimaginable and apprehend the unknown.
