In physics, gravity (from Latin gravitas 'weight' ) is a fundamental interaction which causes mutual attraction between all things with mass or energy . Gravity is, by far, the weakest of the four fundamental interactions, approximately 10 times weaker than the strong interaction, 10 times weaker than the electromagnetic force and 10 times weaker than the weak interaction. As a result, it has no sign… http://www.sciforums.com/threads/gravity-and-curved-space.75834/ plymtree primary school
