Agilent Vacuum Equipment Aids the Discovery of Gravitational Waves Feb 25, 2016

A hundred years ago, physicist Albert Einstein proposed his general theory of relativity. GR theorizes that gravity is a property of space and time.

Energy and mass cause spacetime to distort and curve. Curved spacetime causes matter to move.

As a pictorial example, imagine a flat sheet of material with a marble sitting on it. If you push your finger down in the middle of the material, it will create a dimple. The marble will then roll into the dimple. In the same way, a dimple in spacetime created by the Sun causes the gravitational force that holds the Earth in its orbit.
