Gravitational erosion — is caused by gravity in contrast to the physical movement of wind and water required for other types of soil erosion. Gravitational erosion involves both large scale mass wasting and smaller scale erosion. Forms of gravitational erosion include… … Wikipedia
Gravitational redshift — In physics, light or other forms of electromagnetic radiation of a certain wavelength originating from a source placed in a region of stronger gravitational field (and which could be said to have climbed uphill out of a gravity well) will be… … 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 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
gravitational redshift — Physics, Astron. (in general relativity) the shift toward longer wavelengths of electromagnetic radiation emitted by a source in a gravitational field, esp. at the surface of a massive star. Cf. redshift. * * * … Universalium
gravitational redshift — noun A shift to longer wavelengths of spectral lines emitted by atoms in a strong gravitational field … Wiktionary

Blue shift — is the shortening of a transmitted signal s wavelength, and/or an increase in its frequency, due to the Doppler Effect, which indicates that the object is moving toward the observer. The name comes from the fact that the shorter wavelength end of … Wikipedia
