Read More Go to Site gr Votes:0 gr 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. If you want, you can dive right in and read the adventures of Oz and the Wizard This is the fun part! In these tales, the hapless peasant Oz learns general relativity from a grumpy but powerful wizard. But, unless you are already familiar with general relativity, to follow these adventures you'll need to look at other material from time to time, like this: Short Course Outline Clicking on any of the underlined key concepts will then take you to the corresponding point Read More Go to Site Anyway, it's generally relative Votes:0 Table of contents Previous section Next 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-busters was to realize that there is no physical difference between being pushed deeper into a seat by the acceleration of a fast sports car, or by the attraction of the Earth we sit on: Suitably blindfolded and ear-plugged, to our own senses they are the same. But to study relativity, we need somethin Read More Go to Site AURIGA Home Page Votes:0 Welcome to the AURIGA detector The AURIGA project aims at detecting gravitational waves impinging on the Earth from the Universe. The detector is based on a very low losses ultracryogenic mechanical oscillator: when a burst of gravitational waves hits and excites the oscillator, this will vibrate for a time span much longer than the duration of the burst (typically 1msec), thus allowing the extraction of the signal from the detector noise.

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, which states that the distribution of matter determines space and time, suggests that matter is related to the definition of inertial frames, but Mach never elucidated any means by which this might happen. General relativity attacks this problem and in so doing, discovers that gravity is related to geo Read More Go to Site Doug Eardley's Research Votes:0 Doug Eardley's Research Current interests Criticality and Bifurcation in the Gravitational Collapse of a Self-Coupled Scalar Field Eric W. Hirschmann and Douglas M. Eardley gr-qc/9511052// NSF-ITP-95-154 [ Abstract ] [ Paper ] [ Figure ] This is an extension of our work (gr-qc/9412066, 9505041, 9506078) on Choptuik scaling for gravitational collapse of scalar fields. The matter model is now two real scalar fields, coupled as a non-linear sigma model. The target space is a 2-space of arbitrary constant curvature -2\kappa. This subsumes our previous work on free complex scalar field (9412066 -- flat target space) and on the axion/dilaton fields of low energy string theory (9505041 with Jim Horne -- target space of unit negative curvature), and is also in part equivalent to work by Steve Lieb Read More Go to Site Einstein's Theory of Relativity Votes:0 Theory of Relativity What are black holes?

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 to forces produced by acceleration, so that it is theoretically impossible to distinguish between gravitational and accelerational forces by experiment. In the theory of special relativity, Einstein had stated that a person in a closed car rolling on an absolutely smooth railroad track could not determ Read More Go to Site Gravitational Lensing Votes:0 Gravitational Lensing Topics Background Some background about gravitational lensing.

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 and sometimes magnified. These effects res Read More Go to Site nonlinacoust Votes:0 Welcome to my website!
