Physicists Umberto Cannella and Daniel Whiteson explain what gravitational waves are and why ey'll cause a big ripple in our understanding of e Universe. (Credit: PHD Comics) Gravitational waves are a key prediction of general relativity, a eory proposed by Albert Einstein in 1915 at is still our best explanation for e force of gravity. A gravitational wave is a ripple in e fabric of space and time - if you imagine space as a giant, tightly-pulled sheet of rubber and imagine objects wi mass, like planets and stars, are Missing: Lab meeting.

Gravitational wave, also called gravity wave and gravitational radiation, e transmission of variations in e gravitational field as waves.According to general relativity, e curvature of space-time is determined by e distribution of masses, while e motion of masses is determined by e curvature. In consequence, variations of e gravitational field are transmitted from place to place Missing: Lab meeting. 03/20/18 PHD comic: ' e PHD Movies - Free during e Coronavirus Crisis'. Gravitational waves can be detected indirectly – by observing celestial phenomena caused by gravitational waves – or more directly by means of instruments such as e Ear -based LIGO or e planned space-based LISA instrument..
