An Einstein Ring is a special case of gravitational lensing, caused by the exact alignment of the source, lens, and observer. This results in symmetry around the lens, causing a ring-like structure. [2] The geometry of a complete Einstein ring, as caused by a gravitational lens. The size of an Einstein ring is given by the Einstein radius.
Hendrik Lorentz was a major influence on Einstein's theory of special relativity. Lorentz laid the fundamentals for the work by Einstein and the theory was originally called the Lorentz-Einstein theory. After 1905 Lorentz wrote several papers on what he called "Einstein's principle of relativity". Einstein, Albert (1905-06-30).
The first edition of the book was reviewed by Nature in 1923. [8] Other early versions of the book were reviewed by George Yuri Rainich in 1946, [9] as well as Abraham H. Taub, [10] Philip Morrison, [11] and I. M. Levitt [12] in 1950. Reviews for the book's fifth edition include a short announcement in 1955 that called the book "a well-known ...
Video simulation of the merger GW150914, showing spacetime distortion from gravity as the black holes orbit and merge. The theory of relativity usually encompasses two interrelated physics theories by Albert Einstein: special relativity and general relativity, proposed and published in 1905 and 1915, respectively.

It was first published in German in 1916 and later translated into English in 1920. [1] [2] [3] It is divided into three parts, the first dealing with special relativity, the second dealing with general relativity, and the third dealing with considerations on the universe as a whole. There have been many versions published since the original in ...
Einstein’s general theory of relativity predicts that light will bend around objects in space, so that they focus the light like a giant lens, with this effect being bigger for massive galaxies.
The European Space Agency (ESA) said Monday that its Euclid space telescope has detected a rare bright halo of light around a nearby galaxy.. Known as an Einstein ring, the halo was captured in ...
A new photograph from the Hubble Space Telescope shows a stunning “Einstein Ring” billions of light-years from Earth — a phenomenon named after Albert Einstein.
