Example Sentences
Recent Examples on the Web Damour and his fellow researchers helped develop a theory describing the orbital motion and gravitational radiation as a result of two merging black holes, which played an important role in the direct detection of gravitational waves in 2016. 
Dhananjay Khadilkar, Ars Technica, 18 July 2022 In the last few years, however, gravitational wave astronomy has made great strides in detecting gravitational radiation rippling through spacetime at the speed of light. Bruce Dorminey, Forbes, 10 Nov. 2021 Einstein first predicted that any accelerating mass should emit gravitational radiation in the form of waves. Bruce Dorminey, Forbes, 10 Nov. 2021 This is also the speed that any form of pure radiation, such as gravitational radiation, must travel at, and also the speed, under the laws of relativity, that any massless particle must travel at. Ethan Siegel, Forbes, 12 May 2021 The infall of normal matter, dark matter, neutrinos, and even regular (electromagnetic) radiation vastly outstrips the energy gain from incoming gravitational radiation. Ethan Siegel, Forbes, 18 June 2021 The quantum counterpart of gravitational radiation, the (spin=2) graviton, is only theorized; it has never been measured or detected directly. Ethan Siegel, Forbes, 18 June 2021 And there’s the energy in gravitational waves, a form of gravitational radiation that carries energy away from a system. Ethan Siegel, Forbes, 5 May 2021 Within the past two years simultaneous increases in the output of detectors at these sites have provided evidence of bursts of gravitational radiation emanating from the center of our galaxy.
