Gravity: How the Weakest Force in the Universe Shaped Our Lives

A history of gravity and a study of its importance and relevance to our lives as well as its influence on other areas of science. . Physicists will tell you that four forces control the universe. Of these gravity may the most obvious but it is also the most mysterious. Newton managed to predict the force of gravity but couldnt explain how it worked at a distance. Einstein picked up on the simple premise that gravity and acceleration are interchangeable to devise his mind-bending general relativity showing how matter warps space and time. Not only did this explain how gravity worked – and how apparently simple gravitation has four separate components – but it predicted everything from black holes to gravitys effect on time. Whether its the reality of anti-gravity or the unexpected discovery that a ball and a laser beam drop at the same rate gravity is the force that fascinates.
