Table of contentsPrevious sectionNext Section 10. Anyway, it's generally relative General relativity, and the study of relativistic effects, concerns objects moving at incredibly high speeds, very close to the speed at which photons, the particles of light, hurtle through the cosmos. And it also has to do with processes which occur very close to huge mass concentrations, or equivalently which happen while undergoing strong acceleration. Indeed one of Einstein's fundamental conceptual block-b ...

Relativity and Space-time Gravitational waves are emitted by accelerating masses. Electromagnetic waves are produced when charges are accelerated by electric or magnetic fields. Gravitational waves are produced when masses are accelerated by gravitational fields. In 1919, Sir Arthur Eddington observed the gravitational bending of starlight during a solar eclipse The advance of the perihelion of Mercury. Spacetime is warped around the Sun equivalence principle Quasars can be gravitationally lensed by foreground galaxies to produce multiple images.

Foundations of Modern Cosmology Previous Chapter | Table of Contents | Next Chapter Chapter 8: General Relativity Chapter Summary Special relativity showed that the absolute space and time of Newtonian physics could be only an approximation to their true nature. However, the special theory of relativity is incapable of explaining gravity because SR assumes the existence of inertial frames; it does not explain how inertial frames are to be determined. Mach's principle, whi ...

Einstein's theory of relativity states that gravity is a curvature in space and time. Objects travelling through space follow a straight line through space-time, even though it may appear curved. One implication of this theory is that all objects are affected by gravity, not just those that possess mass. This is a radical departure from Newton's ideas concerning gravity and motion. Einstein predicted that light, which is massless, will be bent by gravity. This prediction was confirmed in 1922 ...

General Theory of Relativity In 1915 Einstein developed the theory of general relativity in which he considered objects accelerated with respect to one another. He developed this theory to explain apparent conflicts between the laws of relativity and the law of gravity. To resolve these conflicts he developed an entirely new approach to the concept of gravity, based on the principle of equivalence. The principle of equivalence holds that forces produced by gravity are in every way equivalent ...

The General Relativity Tutorial John Baez This is bunch of interconnected web pages that serve as an informal introduction to that beautiful and amazingly accurate theory of gravity called general relativity. The goal is to explain the basic equation in this theory - Einstein's equation - with a minimum of fuss and muss. You can begin by reading this: Short Course Outline Clicking on any of the underlined key concepts will then take you to the corresponding point in this more detailed: ...

Introduction to Gravitational Lenses A gravitational lens is an extraordinary astronomical object which is really made up of two separate objects. The necessary parts of a gravitational lens are (1) a luminous object called the SOURCE, and (2) a massive object called the LENS. In order to form a gravitational lens, the SOURCE must be located farther away, yet closely aligned with the LENS. When light from the background source passes by the foreground lens, it will be deflected ...
