Gravity Wave Detectors. In his General Theory of Relativity, Dr Albert Einstein found a solution that modeled an entirely new type of wave: the gravity wave. General Relativity describes the force of gravity as a geometric warping in space-time. If the "warping" were to take the shape of a wave, then this would be a gravity wave.

Made the first gravity wave detector in 1980. Gravity waves from distant events can be detected before the visible light is detected, so the GWD center can alert an optical observatory of an impending super nova. Quantum cosmology. Neutrino astronomy. Malcolm Perry, a student of Stephen Hawking. Gravity waves have amplitude, frequency, and ...

The scattered light requirements for each principal scattering source, at the gravity wave frequencies of interest, are shown in Table 3: Scattered Light Requirements, together with the calculated power scattered into the IFO by that source. 30% of the scattered light budget is used and is allocated to the principal scattering paths ...

Operating these detectors in concert with optical and other astronomical observations, and those from gravity wave detectors, would enhance all methods of observation, sometimes even with non-observation providing key evidence (e.g. as to jets being loaded with nucleons or not).

A balance detector is a device that measures the intensity difference in two laser beams (of the same color) by producing an output voltage that is proportional to the intensity difference of the two laser beams. ... When light travels towards or away from the Earth (up or down), its frequency changes due to gravity. If the frequency of the ...

Experimental evidence that short-period gravity wave activity is inversely proportional to PMC backscattering was provided by Gerrard et al. [1998; see also Thayer et al., 2003]. Lidar backscattering of PMC at Söndrestrom, Norway indicate persistent gravity wave influences with periods of 2 to 3 hours [Thayer et al., 2003].

The strain h takes the form of a plane wave propagating with the speed of light (c). The speed is the same for electromagnetic and gravitational radiation in Einstein’s theory. Since the underlying theory of gravity is spin 2, the waves have two components, like electromagnetic waves, but rotated by 450 instead of 900 from each other.
