Will we ever truly understand our cosmic home? This is the story of the technologies that allow us to look up, to learn and to discover our place in the cosmos. We are part of an incredible chain of events stretching 13.8 billion years into the past and even further into the future. But what does that future hold? And how do scientists study the entire universe? The Universe in a Box is Andrew Pontzen's tribute to simulations - the remarkable computer codes that, over the last century, have allowed us to grasp the distant past and far future of the universe. It reveals the stories of pioneering scientists who unlocked the mysteries of the cosmos, and reframes our understanding of galaxies, black holes and space itself.
