2. Einstein's static universe - Wikipedia

   en.wikipedia.org/wiki/Einstein's_static_universe

   Einstein's static universe, aka the Einstein universe or the Einstein static eternal universe, is a relativistic model of the universe proposed by Albert Einstein in 1917. [1] [2] Shortly after completing the general theory of relativity, Einstein applied his new theory of gravity to the universe as a whole.

3. Static universe - Wikipedia

   en.wikipedia.org/wiki/Static_universe

   Einstein's static universe is closed (i.e. has hyperspherical topology and positive spatial curvature), and contains uniform dust and a positive cosmological constant with value precisely = /, where is Newtonian gravitational constant, is the energy density of the matter in the universe and is the speed of light.

4. Albert Einstein - Wikipedia

   en.wikipedia.org/wiki/Albert_Einstein

   The Einstein-de Haas experiment is the only experiment concived, realized and published by Albert Einstein himself. A complete original version of the Einstein-de Haas experimental equipment was donated by Geertruida de Haas-Lorentz , wife of de Haas and daughter of Lorentz, to the Ampère Museum in Lyon France in 1961 where it is currently on ...

5. Friedmann–Einstein universe - Wikipedia

   en.wikipedia.org/wiki/Friedmann–Einstein_universe

   The Friedmann–Einstein universe is a model of the universe published by Albert Einstein in 1931. [1] The model is of historic significance as the first scientific publication in which Einstein embraced the possibility of a cosmos of time-varying radius.

6. Cosmological constant - Wikipedia

   en.wikipedia.org/wiki/Cosmological_constant

   The cosmological constant was originally introduced in Einstein's 1917 paper entitled “The cosmological considerations in the General Theory of Reality”. [2] Einstein included the cosmological constant as a term in his field equations for general relativity because he was dissatisfied that otherwise his equations did not allow for a static universe: gravity would cause a universe that was ...

7. Theory of relativity - Wikipedia

   en.wikipedia.org/wiki/Theory_of_relativity

   Albert Einstein, physicist, 1879-1955, Graphic: Heikenwaelder Hugo,1999 Special relativity is a theory of the structure of spacetime . It was introduced in Einstein's 1905 paper " On the Electrodynamics of Moving Bodies " (for the contributions of many other physicists and mathematicians, see History of special relativity ).

8. Einstein–de Sitter universe - Wikipedia

   en.wikipedia.org/wiki/Einstein–de_sitter_universe

   The Einstein–de Sitter universe is a model of the universe proposed by Albert Einstein and Willem de Sitter in 1932. [1] On first learning of Edwin Hubble's discovery of a linear relation between the redshift of the galaxies and their distance, [2] Einstein set the cosmological constant to zero in the Friedmann equations, resulting in a model of the expanding universe known as the Friedmann ...

9. Theory of everything - Wikipedia

   en.wikipedia.org/wiki/Theory_of_everything

   After 1915, when Albert Einstein published the theory of gravity (general relativity), the search for a unified field theory combining gravity with electromagnetism began with a renewed interest. In Einstein's day, the strong and the weak forces had not yet been discovered, yet he found the potential existence of two other distinct forces ...
