General Relativity consists of the mathematical equations that provide such a characterization consistent with Newton's laws and Special Relativity. It relegates gravitational force to be an artifact, like centrifugal force or Coriolis Force. It was developed by Einstein in 1916 following his earlier development of Special Relativity. General Relativity remains the current favored model of gravity, based on its unique ability to explain the common, intuitive behavior of gravity as well as observed extreme cases that defy the common behavior.
The formula is known as
1 8π
μ and ν each indicate the four dimensions of space-time,
i.e., *R*_{μν}- Ricci curvature tensor.*R*- scalar Curvature.*g*_{μν}- metric tensor.- Λ - Cosmological Constant.
*G*- Newton's gravitational constant.- c - speed of light.
*T*_{μν}- stress energy tensor.
Of interest is Λ, the Cosmological Constant, which Einstein included to compensate for the formula's implication that the universe would otherwise be expanding or contracting. Upon Edwin Hubble's later discovery of the visible expansion of the universe, Einstein no longer saw reason to include it. More recent observations showing expansion not following General Relativity's predictions has induced physicists to revive the "constant", as a rug under which they can sweep the unexplained visible phenomena, also known as Dark Energy. equation,physics,relativity,geometry)http://preposterousuniverse.com/grnotes/grtinypdf.pdf Referenced by:
