Gravitational wave astronomy — is an emerging branch of observational astronomy which aims to use gravitational waves (minute distortions of spacetime predicted by Einstein s theory of general relativity) to collect observational data about objects such as neutron stars and… … Wikipedia
Gravitational wave — In physics, a gravitational wave is a fluctuation in the curvature of spacetime which propagates as a wave, traveling outward from a moving object or system of objects. Gravitational radiation is the energy transported by these waves. Important… … Wikipedia
Gravitational wave background — A possible target of gravitational wave detection experiments is a stochastic background of gravitational waves. The detection of such a background would have a profound impact on early universe cosmology and on high energy physics, opening up a… … Wikipedia
gravitational radiation — ▪ physics the transmission of variations in the gravitational field as waves. According to general relativity (relativity), the curvature of space time is determined by the distribution of masses, while the motion of masses is determined by the… … Universalium
