The speed of gravitational waves in the general theory of relativity is equal to the speed of light in vacuum, c. [3] Within the theory of special relativity, the constant c is not only about light; instead it is the highest possible speed for any interaction in nature.

At a fixed point on the surface, the magnitude of Earth's gravity results from combined effect of gravitation and the centrifugal force from Earth's rotation. [ 2 ] [ 3 ] At different points on Earth's surface, the free fall acceleration ranges from 9.764 to 9.834 m/s 2 (32.03 to 32.26 ft/s 2 ), [ 4 ] depending on altitude , latitude , and ...
Scientists involved in the project and the analysis of the data for gravitational-wave astronomy are organized by the LSC, which includes more than 1000 scientists worldwide, [7] [8] [9] as well as 440,000 active Einstein@Home users as of December 2016. [10] LIGO is the largest and most ambitious project ever funded by the NSF.
The graviton's Compton wavelength is at least 1.6 × 10 16 m, or about 1.6 light-years, corresponding to a graviton mass of no more than 7.7 × 10 −23 eV/c 2. [18] This relation between wavelength and mass-energy is calculated with the Planck–Einstein relation , the same formula that relates electromagnetic wavelength to photon energy .
A science project is an educational activity for students involving experiments or construction of models in one of the science disciplines. Students may present their science project at a science fair, so they may also call it a science fair project. Science projects may be classified into four main types.
In the limit, when the fundamental speed of gravity becomes infinite, the post-Newtonian expansion reduces to Newton's law of gravity. The parameterized post-Newtonian formalism or PPN formalism , is a version of this formulation that explicitly details the parameters in which a general theory of gravity can differ from Newtonian gravity.
If the speed is the orbital speed at that altitude, it will go on circling around the Earth along a fixed circular orbit "and return to the mountain from which it was projected". If the speed is higher than the orbital velocity, but not high enough to leave Earth altogether (lower than the escape velocity ), it will continue revolving around ...
