  1. Dec 12, 2017 · Ana Alvarez Roldan. General relativity is Einstein's theory developed in 1915 that describes gravity as a geometric property of space and time. It introduced the idea that massive objects cause a curvature in spacetime, which is felt as gravity. The theory says that the space-time around Earth would be warped and twisted by the planet's rotation.

  4. Newton’s theory gives a very accurate theory for objects moving at slow speeds in absence of strong gravitational elds. However, in several circumstances di culties arise: 1.A more philosophical issue is that in Newtonian theory an observer is either at rest or in motion. But how could one determine if an observer Ois (universally) at rest?
