The strategy was to compare observed Doppler shifts with what was predicted by classical theory, and look for a Lorentz factor correction.

The final form of general relativity was published in Retrieved 14 April Far from being simply of theoretical interest, relativistic effects are important practical engineering concerns. Special relativity is based on two postulates which are contradictory in classical mechanics :. The theory transformed theoretical physics and astronomy during the 20th century, superseding a year-old theory of mechanics created primarily by Isaac Newton.

The term "theory of relativity" was based on the expression "relative theory" German : Relativtheorie used in by Planck, who emphasized how the theory uses the principle of relativity. Geological time age chron eon epoch era period Geochronology Geological history of Earth. Bibcode : JOSA Equivalence principle Riemannian geometry Penrose diagram Geodesics Mach's principle. Technically, general relativity is a theory of gravitation whose defining feature is its use of the Einstein field equations. Gravitational redshift : The electromagnetic radiation of an object is stretched out slightly inside a gravitational field. Added to Watchlist. In a few billion years, it could even collide with Earth. Classical mechanics Acoustics Classical electromagnetism Optics Thermodynamics Statistical mechanics. Relativity: The Special and General Theory.

Einstein's theory of general relativity predicted that the space-time around Earth would be not only warped but also twisted by the planet's rotation. In , he devised the Einstein field equations which relate the curvature of spacetime with the mass, energy, and any momentum within it. Theoretical Computational Experimental Applied.

The theory transformed theoretical physics and astronomy during the 20th century, superseding a year-old theory of mechanics created primarily by Isaac Newton.

As astronomical phenomena were discovered, such as quasars , the 3-kelvin microwave background radiation , pulsars , and the first black hole candidates , [3] the theory explained their attributes, and measurement of them further confirmed the theory. Geology Geological time age chron eon epoch era period Geochronology Geological history of Earth. Main articles: History of special relativity and History of general relativity. Two objects exert a force of attraction on one another known as "gravity. Those classic experiments have been repeated many times with increased precision.
