GRAVITATIONAL PHYSICS SPACE AND TIME A B ... CONTACT entire Web this site general theory of relativity Albert Einstein's theory of gravity which describes gravitational forces in terms of the curvature of spacetime caused by the presence of mass . As the American physicist John Wheeler put it: "Space tells matter how to move; matter tells space how to curve." The starting principle of the general theory, known as the equivalence principle , is that frames of reference undergoing acceleration and frames of reference in gravitational fields are equivalent. Among its predictions, which have been borne out by observation, are the advance of the perihelion of Mercury , the bending of light in a gravitational field (including gravitational lenses ), and the spin-down of pulsars (due to the emission of gravitational waves , which have yet to be detected directly). Also predicted by general relativity is that time runs more slowly in strong gravitational fields. General relativity treats special relativity as a restricted sub-theory that applies locally to any region of space sufficiently small that its curvature can be neglected.

Home English Hebrew Understanding General Relativity too Table of Content The Principles of General Relativity Background The equivalence principle Gravity as Curvature ... A Model of the Universe Understanding General Relativity too By Rafi Moor The purpose of this article is to introduce General Relativity to people with basic knowledge of mathematics and physics. Familiarity with the basics of Special Relativity is also required. Talking about General Relativity without getting into higher mathematics is not an easy mission. Much of the theory of GR deals with advanced mathematical issues. One can't cover the main topics of GR without getting into some mathematical issues. I have divided the article to three parts so that the reader can decide how deep he wants to dive into the subject. The first part introduces the principles of GR without any mathematics at all. The second part discusses curved space geometry without getting into the detailed mathematics of it. The third part describes Einstein's field equation and some consequences of it.

Werner Benger Photon.at [Turn off Background] Raytracing using hyperbolic light paths Presented during the Alpbach Summer School 1992. Unfortunately, I have no idea where I put the images from this ancient presentation... Simulation of a Black Hole by Raytracing In this simulation it is shown what happens to a natural scene when one of these objects where a Black Hole. The bending of the light rays around a `soccerball-like' Black Hole makes normally invisible parts of the involved objects to come into view. Basic principles of gravitational lensing are demonstrated on ordinary objects and the meaning of the Einstein ring is explained also. Published in: F.W.Hehl, R.A.Puntigam, H.Ruder (Eds.)

Monday, near seven in the evening Tuesday, a little after midnight I'm tired now. Relieved to be almost home, and for some reason still wired from traveling. I keep thinking about the man next to me, who gripped the arm rest, white knuckled, as we landed. And the baby, who never made a sound. Posted by mandy at 2:13 PM 6 comments: Jo said...

Guys aren't the same 7:21 AM jess said... oh, i split myself into multiples all the time. this is just beautiful. beautiful. i'm not sure i can live this yet, but what i learned from my biggest heartbreak was that even when you invest in someone else, and they give you nothing back, the only thing you've lost is a sense of hope in who they could be to you. any person who can't return what you offer, or at least value what you give, isn't stronger than you because of what they withhold. instead, i think, they show the sadness or hollowness or whatever inside them by the emptyness that they return to love. does that make any sense?

acceleration disk A sheet of gas and dust surrounding any massive object growing in size by attracting material. accretion disk A disk shape formed by gas as it spirals into a black hole. atom The basic unit of matter. binary star system A system in which two stars orbit around a common center of mass. black hole A region of space-time formed by the collapse of a massive object, such as a star. A black hole is coined "black" because nothing, not even light, can escape its grasp. cosmic censorship hypothesis States that the singularities produced by gravitational collapse must be hidden behind an event horizon. Doppler effect Relationship between wavelength and speed where shifting of wavelength occurs when the movement of an object is away or towards an observer. event horizon The boundary of a black hole. The point of no return. frame dragging As a black hole rotates, it drags space and time around itself. general relativity Albert Einstein's theory that proposes that gravity is a curvature of four-dimensional space-time caused by the presence of matter. gravitation One of the two main processes in a star in which hydrogen is pulled back to the star's center.

68. New Observations Of Black Holes Confirm General Relativity science news from the NASA Marshall Space Sciences Lab. http://science.nasa.gov/newhome/headlines/ast06nov97_1.htm

Einstein was right...again!!! Satellite observations of Black Holes confirm frame-dragging effect 80 years after prediction November 6, 1997: T he next time you feel like you're barely dragging along, blame relativity. You'll be stretching the point, but it appears that Einstein was right: space and time get pulled out of shape near a rotating body. Einstein predicted the effect, called ``frame dragging,'' 80 years ago. Like many other aspects of Einstein's famous theories of relativity, it's so subtle that no conventional method could measure it. Using recent observations by X-ray astronomy satellites, including NASA's Rossi X-ray Timing Explorer , a team of astronomers is announcing that they see evidence of frame dragging in disks of gas swirling around a black hole. The discovery will be announced today at a meeting of the High Energy Astrophysics Division of the American Astronomical Society in Estes Park, Colo., by Dr. Wei Cui of the Massachusetts Institute of Technology, and his colleagues, Dr. Nan Zhang

Along with the Santiago Calatrava-designed PATH Transportation Hub, the three towers, bounded by Church Street to the east and a reintroduced Greenwich Street to the west, will occupy the length of the east side of the World Trade Center site. In keeping with the Libeskind master plan for the site, the towers will form a descending spiral toward the Memorial and will include 6.2 million square feet of office space and a half million square feet of interconnected and contiguous first-class retail. The three towers were designed to seamlessly integrate with what will be newly-created pedestrian thoroughfares along the reconnected grid at Cortlandt and Dey Streets, the WTC Transportation Hub, which sits between the towers at 200 and 175 Greenwich, and the rest of the downtown neighborhood, including the Fulton Street Transit Center.
