University of California, San Diego Gene Smith's Astronomy Tutorial Einstein's General Theory of Relativity The General Theory of Relativity is an expansion of the Special Theory to include gravity as a property of space. Start with this Gravity Tutorial The Equivalence Principle The Theory of Special Relativity has as its basic premise that light moves at a uniform speed, c = 300,000 km/s , in all frames of reference. This results in setting the speed of light as the absolute speed limit in the Universe and also produced the famous relationship between mass and energy, E = mc . The foundation of Einstein's General Theory is the Equivalence Principle which states the equivalence between inertial mass and gravitational mass Inertial Mass is the quantity that determines how difficult it is to alter the motion of an object. It is the mass in Newton's Second Law: F = ma Gravitational mass is the mass which determines how strongly two objects attract each other by gravity, e.g. the attraction of the earth: It is the apparent equivalence of these two types of mass which results in the uniformity of gravitational acceleration Galileo's result that all objects fall at the same rate independent of mass: Galileo and Newton accepted this as a happy coincidence, but Einstein turned it into a fundamental principle. Another way of stating the equivalence principle is that gravitational acceleration is indistinguishable from other forms of acceleration. According to this view a student in a closed room could not tell the difference between experiencing the gravitational pull of the earth at the earth's surface and being in a rocketship in space accelerating with a = 9.8 m/s

Special And General Relativity - New Mathematical Formulations Presentation of new mathematical formulations for both the Special and General Theories of Relativity.Category Science Physics Relativity Alternative......Mathematical knowledge required is no greater than undergraduate level.SPECIAL AND general relativity NEW MATHEMATICAL FORMULATIONS. http://www.relativitydomains.com/

SPECIAL AND GENERAL RELATIVITY - NEW MATHEMATICAL FORMULATIONS The purpose of this site is the presentation of new, simplified mathematical formulations of Albert Einstein's Special and General Theories of Relativity. The content is therefore of a technical nature, requiring a good working knowledge of mathematics and applied mechanics, up to graduate level. The current literature on these theories primarily works with such techniques as Riemannian Geometry and the Tensor Calculus etc., and while these are extremely powerful mathematical tools, they are also very complex. Therefore, when applied to Einstein's two most well known theories, they result in a formulation quite difficult to follow for even the most accomplished post graduate student. In the presentations here, nothing more complex than first and second order differential equations of functions of a complex variable are used to develop both theories from first principles.The first paper should be reviewed first because it is the simpler of the two, and because the paper on the General Theory assumes a familiarity with the application of the above techniques to these subjects. The links below connect with short introductory pages to each paper and to links to the sections of the papers themselves.

Taylor and John Archibald Wheeler Addison Wesley Longman Albert Einstein told us that a star or other massive object distorts spacetime in its vicinity. Sufficient distortion makes it impossible to describe matter and motion with the single "inertial reference frame" used in Newton's theory of mechanics and Einstein's theory of special relativity. General relativity describes the distortion of spacetime near a star, white dwarf, neutron star, or black hole and predicts the resulting motion of stones, satellites, and light flashes. Learning general relativity usually requires mastering Einstein's field equations, which are expressed in the complicated mathematics of tensors or differential forms. But big chunks of general relativity require only calculus if one starts with the metric describing spacetime around Earth or black hole. Expressions for energy and angular momentum follow, along with predictions for the motions of particles and light. Students study the Global Positioning system, precession of Mercury's orbit, gravitational red shift, orbits of light and deflection of light by Sun, the gravitational retardation of light, and frame-dragging near a rotating body.

Black Holes and Singularities subject listing A black hole is a region of such high gravity that not even light can escape its pull. They are created when very large stars exhaut their fuel and collapse down to form very dense, massive objects. In general relativity's more accurate definition of gravity, an extremely dense object can create an enourmous curvature of spacetime, trapping even light.

General relativity: a very weird world This is the English translation of a webpage originally written in French , by Nymbus , who also provided the translation. I've agreed to post it here at my own website, and have cleaned up the translation a bit, editing for grammar, and so on, but leaving the content untouched, I think. So any comments or questions should be addressed to nymbus@wanadoo.fr . It's his project. (Although, if there's a problem with the page such as the images not showing up or special characters not appearing, send word to me .) Dave This page has also been translated into Spanish At times, this page alludes to concepts from the special theory of relativity, which are explored here General relativity: a brief explanation of the fundamentals ideas Before beginning this brief article, dealing with the essential features of general relativity, we have to postulate one thing: special relativity is supposed to be true. Hence, general relativity lies on special relativity. If the latter were proved to be false, the whole edifice would collapse. In order to understand general relativity, we have to define how mass is defined in classical mechanics.
