How do we measure gravitational waves
WebJul 3, 2010 · A good way of picturing gravitational waves is imagining the universe as a stretched-out piece of fabric. Planets and stars sitting on the fabric pull it out of shape, … WebLIGO currently consists of two interferometers, each with two 4 km (2.5 mile) long arms arranged in the shape of an “L”. These instruments act as 'antennae' to detect gravitational waves. In the links below, you will learn …

WebA gravitational wave may travel at the speed c, but also below depending on the amplitude. Essentially, it employs spacetime itself as a medium. A particular wave metric: d s 2 = d t 2 − d r 2 + H ( t − r, x 1, x 2) ( d t − d r) 2 − d ( x 1) 2 − d ( x 2) 2 WebDec 8, 2024 · In simple Newtonian terms, a gravitational potential measures how much energy an object would gain if it fell from a certain height. Drop an anvil off a cliff, and the speed of the anvil at the bottom can be used to reconstruct the “potential” energy that falling off the cliff can impart.
