  2. Speed of gravity - Wikipedia

    en.wikipedia.org/wiki/Speed_of_gravity

    The speed of gravity (more correctly, the speed of gravitational waves) can be calculated from observations of the orbital decay rate of binary pulsars PSR 1913+16 (the Hulse–Taylor binary system noted above) and PSR B1534+12. The orbits of these binary pulsars are decaying due to loss of energy in the form of gravitational radiation.

    In 1992, John Moffat proposed that the speed of light was much larger in the early universe, in which the speed of light had a value of more than 10 30 km/s. [2] He published his " variable speed of light " (VSL) theory in two places—on the Los Alamos National Laboratory's (LANL) online archive, 16 Nov. 1992, [ 4 ] and in a 1993 edition of ...

  6. Gravitational wave - Wikipedia

    en.wikipedia.org/wiki/Gravitational_wave

    Speed: This is the speed at which a point on the wave (for example, a point of maximum stretch or squeeze) travels. For gravitational waves with small amplitudes, this wave speed is equal to the speed of light (c). The speed, wavelength, and frequency of a gravitational wave are related by the equation c = λf, just like the equation for a ...

    en.wikipedia.org/wiki/History_of_gravitational...

    The 12th-century scholar Al-Khazini suggested that the gravity an object contains varies depending on its distance from the centre of the universe (referring to the centre of the Earth). Al-Biruni and Al-Khazini studied the theory of the centre of gravity, and generalized and applied it to three-dimensional bodies.
