Time moves slower the closer you are to Earth. In his theory of general relativity, Einstein explained that the gravity of a large mass, like Earth, distorts the space and time around it.

In 2010, researchers placed two precise atomic clocks, one 33 centimetres higher than...

Theory of General and Special Relativity are both immensely well known theories that discuss gravity in some aspect or another. 

The chief difference that can be made between them is the level of completeness. But what exactly does each theory talk about?

General Relativity

The reason Einstein’s theory of general relativity works well in lower energy calculations and standard quantum techniques but not in higher energies and scales (like a black hole), could be because certain key features or ingredients of gravity are yet unknown to us, and are therefore missing fr...
