Confirmation of Einstein's theory came in 1919 in the wake of an expedition led by Arthur Eddington to photograph the eclipse of May 29, 1919. But some uncertainty remained, as well as scepticism fueled in part by anti-German sentiment in the wake of World War I. Final and uncontested confirmation is generally dated to Campbell's 1922 Lick ...
The aim of the expeditions was to measure the gravitational deflection of starlight passing near the Sun. [1] The value of this deflection had been predicted by Albert Einstein in a 1911 paper; however, this initial prediction turned out not to be correct because it was based on an incomplete theory of general relativity.
1915 – Albert Einstein: General relativity; 1915 – Emmy Noether: Noether's theorem relates symmetries to conservation laws. 1916 – Schwarzschild metric modeling gravity outside a large sphere; 1917 - Ernest Rutherford: Proton proved; 1919 – Arthur Eddington:Light bending confirmed – evidence for general relativity
Theodor Franz Eduard Kaluza (German: [kaˈluːt͡sa]; 9 November 1885 – 19 January 1954) was a German mathematician and physicist known for the Kaluza–Klein theory, involving field equations in five-dimensional space-time. His idea that fundamental forces can be unified by introducing additional dimensions was reused much later for string ...
His working theory is based on Albert Einstein’s relativity discussion. The prototype laser loop he developed ends up bending time, hypothetically allowing movement back—at the farthest—to ...
1911 – Albert Einstein explains the need to replace both special relativity and Newton's theory of gravity; he realizes that the principle of equivalence only holds locally, not globally. [53] 1912 – Friedrich Kottler applies the notion of tensors to curved spacetime. [54] [52] 1915-16 – Albert Einstein completes his general theory of ...
Einstein showed in 1915 how his theory explained the anomalous perihelion advance of the planet Mercury without any arbitrary parameters ("fudge factors"), [12] and in 1919 an expedition led by Eddington confirmed general relativity's prediction for the deflection of starlight by the Sun during the total solar eclipse of 29 May 1919, [13 ...
The term "theory of relativity" was based on the expression "relative theory" (German: Relativtheorie) used in 1906 by Planck, who emphasized how the theory uses the principle of relativity. In the discussion section of the same paper, Alfred Bucherer used for the first time the expression "theory of relativity" (German: Relativitätstheorie ...
