Having solved the mystery of gravity, we can answer the greatest questions of science: what is space? What is time? What is the universe? Where did all this come from? Celebrated popular science author Marcus Chaun takes you on a fascinating journey - from the moment gravity was recognised as a physical force in 1666 to the discovery of gravitational waves in 2015. A tectonic shift in our ideas about physics is approaching, and this book tells what questions the phenomenon of gravity poses for us.
