3 days ago · He came up with this idea using Albert Einstein’s theory of general relativity, which stated that curvatures in spacetime explain gravity. Lemaître’s idea of the Big Bang was astounding, but it lacked proof and contradicted the common belief that the universe was static (neither expanding nor contracting).
23 hours ago · In this series, I’m discussing how ideas from calculus and precalculus (with a touch of differential equations) can predict the precession in Mercury’s orbit and thus confirm Einstein’s theory of general relativity. The origins of this series came from a class project that I assigned to my Differential Equations students maybe 20 years ago.

4 days ago · Albert Einstein proposed [3] [4] three tests of general relativity, subsequently called the "classical tests" of general relativity, in 1916: the perihelion precession of Mercury 's orbit. the deflection of light by the Sun. the gravitational redshift of light. In the letter to The Times (of London) on November 28, 1919, he described the theory ...
4 days ago · Albert Einstein (born March 14, 1879, Ulm, Württemberg, Germany—died April 18, 1955, Princeton, New Jersey, U.S.) was a German-born physicist who developed the special and general theories of relativity and won the Nobel Prize for Physics in 1921 for his explanation of the photoelectric effect.

5 days ago · At speeds that are a substantial fraction of the speed of light, the framework of Newtonian mechanics no longer suffices to describe many physical phenomena. Instead, one must start to take into account Einstein's theory of special relativity, which deals with the "special" case of physics in the absence of gravity. The more "general" case of general relativity takes ...
