General relativity  Wikipedia
General relativity (GR, also known as the general theory of relativity or GTR) is the geometric theory of gravitation published by Albert Einstein in 1915 and the current description of gravitation in modern physics.General relativity generalizes special relativity and Newton's law of universal gravitation, providing a unified description of gravity as a geometric property of space and time ...
Introduction to general relativity  Wikipedia
General relativity is a theory of gravitation that was developed by Albert Einstein between 1907 and 1915. According to general relativity, the observed gravitational effect between masses results from their warping of spacetime.. By the beginning of the 20th century, Newton's law of universal gravitation had been accepted for more than two hundred years as a valid description of the ...
General Relativity explained like you've never seen before
For 100 years, the general theory of relativity has been a pillar of modern physics. The basic idea is so elegant that you don’t need superpowers to understand it.

Gravitational Red Shift According to the principle of equivalence from general relativity, any frequency shift which can be shown to arise from acceleration of a radiating source could also be produced by the appropriate gravitational field. If a photon of frequency υ 0 is emitted radially outward from the surface of a gravitational mass M, then the photon energy observed at a distance from ...

Gravity Probe B: Testing Einstein's Universe
GPB was designed to measure two key predictions of Einstein's general theory of relativity by monitoring the orientations of ultrasensitive gyroscopes relative to a distant guide star.

Relativity Tutorial
Relativity can be described using spacetime diagrams. Contrary to popular opinion, Einstein did not invent relativity. Galileo preceded him. Aristotle had proposed that moving objects (on the Earth) had a natural tendency to slow down and stop. This is shown in the spacetime diagram below. Note ...
Einstein's Zurich Notebook  University of Pittsburgh
Einstein's search for general relativity spanned eight years, 19071915. Some periods were quiet and some were more intense. The moments when the great transition occurred, came sometime between the late summer of 1912, when Einstein moved from Prague to Zurich, and early 1913.If we could choose one time at which to look over Einstein's shoulder and watch him work on general relativity, it ...
