The general theory of relativity is much more complex and difficult to understand than the special theory. It proves the force of Gravitation, as proved by Sir Isaac Newton, wrong. According to Newton, gravity was a force between two bodies, which depends on their respective mass and the distance between them. \nThe basic idea of general relativity can be illustrated with the help of an imaginary experiment as performed by Einstein.  Suppose a lift is at rest in space.  If a ball is released within the lift, it will float in space and not fall.  If the lift accelerates upward, an observer within the lift will see the ball fall to the floor exactly as it would under the pull of gravity.  The ball appears to fall because the floor of the lift, as seen from outside the lift, it accelerates upward toward the ball.  All the effects we associate with gravity would be seen by the observer in the lift.  Einstein called the phenomenon shown in this experiment the Principle of Equivalence. This principle states that it makes no difference whether an object is acted on by a gravitational force or is in an accelerated frame of reference.  The result in both cases will be the same.  From this principle, Einstein reasoned that matter in space distorts or "curves" the frame of reference of space. The result of this curvature is what we experience as gravity. The Euclidian or flat geometry was unable to explain the curve, so Einstein used geometries called Riemannian geometry to explain the effect. \nAccording to Newton's theory, a planet moves around the sun because of the gravitational force exerted by the sun.  According to the theory of general relativity, the planet chooses the shortest possible path throughout the four-dimensional space- time, which is deformed by the presence of the sun. This shortest possible path is called a geodesic.  This may be compared to the fact that a ship or an aeroplane crossing the ocean follows the section of a circle, rather than a straight line, in order to travel the shortest route between two points.  In the same way, a planet or light ray moves along the "shortest" line in its four-dimensional world. \nSo far, three things have been discovered in which Einstein's theory of general relativity receives experimental proof as opposed to the theories of Newton.  These differences are not great, but are measurable.  In the first place, according to Newton's theory, the planet Mercury moves in an ellipse about the sun.  According to Einstein's theory, Mercury moves along an ellipse, but at the same time the ellipse rotates very slowly in the direction of the planet's motion.  The ellipse will turn about forty-three seconds of an arc per century (a complete rotation contains 360 degrees of an arc and 360 X 60 X 60 seconds of an arc).  This effect is rather small, but it has been observed.  Mercury is nearest to the sun and the relativistic effect would be still smaller for other planets.  \nIf we take a picture of part of the heavens during an eclipse of the sun and near the eclipsed sun, and then take another picture of the same part of the heavens a little later, the two photographs will not show identical positions for all the stars.  This is so because, according to general relativity, a light ray sent by a star and passing near the rim of the sun is deflected from its original path because the sun's gravity curves space.  The effect of gravity on light is also the reason why black holes are invisible.  The gravitation in a black hole is so strong that light cannot escape from it. \nPhysicists have known for more than a hundred years that when some elements are heated to incandescence they give off a pattern of spectral lines (coloured lines), which can be examined through a spectroscope.  According to the Einstein theory, the wavelength of light emitted from a massive object will become longer because of gravitation.  This results in a shift of the spectral lin

Isaac Newtwon laid down the ground work for modern day physics.  Then Einstein came along and published the most recent great discovery in physics, the theory of relativity.  The problem is, these two contradict each other.  Steven Hawkings and others have since been working with string theory, which would explain these contradictions.

If you can't find it in bound volumes - someone should have it in microfilm - probably at a large state university.  This is the weekly newsletter of the American Geophysics Union.\n\nhttp://www.agu.edu only goes back to 1988.\n\nThe University of Maryland College Park has this:\nhttp://catalog.umd.edu/F/RUSR6UH742HLFTV52GR3P8UMLV614EXCUSE8YIIT76CF4GETR1-00229?func=find-b&find_code=WRD&request=Trans.+Am.+Geophys.+Union

I would highly recommend the last answer. BRIAN GREENE's\nThe Elegant Universe. Great Book, I read it and it explains a lot in real English. Also check out his other book, which is also a great book on string theory its call "The fabric of the Cosmos"(great title!), a little more complex but highly usefull. Or if you hate to read, then buy the Nova special on string theory, which is hosted by Brian Greene (the author). He is one the lead string theorists. Mabye the next Einstein? (Possibly). I would watch the movie first. Then read the book, you would understand the material better with visuals.

There are actually two parts to the "theory of relativity".\n\nThe General and the Special Relativity.\nGeneral relativity was developed by Einstein in the years 1911 - 1915. General relativity is a geometrical theory which postulates that the presence of matter "curves" spacetime, and this curvature affects the path of free particles (and even the path of light). It uses the mathematics of differential geometry and tensors in order to describe gravitation without the use of the force of gravity. This theory considers all observers to be equivalent, not only those moving with uniform speed.\n\nAlbert Einstein's 1905 paper "On the Electrodynamics of Moving Bodies" introduced the special theory of relativity. Special relativity considers that observers in inertial reference frames, which are in uniform motion relative to one another, cannot perform any experiment to determine which one of them is "stationary". This is known as the principle of relativity. While this principle was not new to Albert Einstein's work, he found that including electromagnetism in this principle required a new formalism with many surprising consequences. In particular, it required the speed of light in a vacuum to be the same for all these observers, regardless of their motion or the motion of the source of the light.\n\nOne of the strengths of special relativity is that it can be derived from only two premises:\n\n    * The laws of physics are the same in any inertial frame of reference. This means that the laws of physics observed by a hypothetical observer traveling with a relativistic particle must be the same as those observed by an observer who is stationary in the laboratory.\n    * The speed of light in a vacuum is constant (specifically, 299,792,458 meters per second).
