	Theory of relativity - Wikipedia, the free encyclopedia
		Albert Einstein's theory of relativity is a set of two scientific theories in physics: special relativity and general 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 in "absolute motion".
		General relativity is a geometrical theory which postulates that the presence of mass and energy "curves" spacetime, and this curvature affects the path of free particles (and even the path of light).

		8 The Geometry of Space-time in Special Relativity
		Special relativity is usually concerned with the behaviour of objects and observers which remain at rest or are moving at a constant velocity.
		Special relativity shows, in fact, that these concepts are all different aspects of the same physical quantity in much the same way that it shows space and time to be interrelated.

	STR: A Brief History of Einstein's Special Theory of Relativity
		A theory in physics is generally thought to be true when it corresponds to what exists, and if the special theory of relativity does not correspond to material objects in absolute space, we want to know what it does correspond to.
		Einstein's special theory of relativity was a better efficient-cause explanation of the relevant phenomena than Lorentz's way of defending his transformation equations, because it made all the same precise predictions of measurements, but in a mathematically simpler way.
		The acceptance of Einstein’s special theory of relativity involved, however, a remarkable change in the empirical method of physics, for it involved the abandonment of the requirement that explanations in physics be intuitively intelligible.

	General Relativity
		In 1916 Einstein expanded his Special Theory to include the effect of gravitation on the shape of space and the flow of time.
		When "generalized" to include gravitation, the equations of relativity predict that gravity, or the curvature of spacetime by matter, not only stretches or shrinks distances (depending on their direction with respect to the gravitational field) but also w ill appear to slow down or "dilate" the flow of time.
		In the decade after its publication in 1916, Einstein's Theory of General Relativity led to a burst of experimental activity in which many of its predictions were vindicated.

	The Theory of Special Relativity
		The special theory of relativity as expounded by Einstein in 1905 is based on the argument that since all attempts to detect motion through the aether fail, the assumption of a "privileged background" is superfluous.
		The latter effect differs from that predicted by Einstein's special theory of relativity in that it is a real slowing and is not reciprocated by an apparent slowing of clocks on earth as seen by the satellite.
		I believe Einstein's theories of special relativity and general relativity to be wrong because they describe the universe as having a fourth dimension of time in addition to the three dimensions of length width and height.

	Proof of the Falsity of the Special Theory of Relativity (Site not responding. Last check: 2007-11-06)
		To proof relativity theory wrong it is not enough to show the errors in the several existing mathematical derivations of the transformation equations, since it might always be possible to derive a new one in the future.
		The idea came out of an ether theory in which the earth (and all objects on it) was thought to get contracted in length in the direction of its motion around the sun, whilst moving through a medium for light-waves (which was supposed to be at rest with respect to the sun).
		However, when with the advent of relativity theory the notion of the ether was discarded, the physical possibility of a contraction was also taken away.

	What's So Special About Relativity? (Site not responding. Last check: 2007-11-06)
		Einstein's first theory of relativity, which he published in 1905, broke away from the Newtonian reliance on space and time as immutable frames of reference.
		Later to become known as the Special Theory of Relativity, its first postulate was that the speed of light is the same for all observers, regardless of their motion relative to the source of the light.
		Einstein's 1905 theory is referred to as the "special" theory because it is limited to bodies moving in the absence of a gravitational field.

	Theory: Special Relativity
		Einstein's Special Theory of Relativity describes the motion of particles moving at close to the speed of light.
		Einstein's theory is now very well established as the correct description of motion of relativistic objects, that is those traveling at a significant fraction of the speed of light.
		One of the strangest parts of special relativity is the conclusion that two observers who are moving relative to one another, will get different measurements of the length of a particular object or the time that passes between two events

	General relativity
		General relativity is a theory of gravitation and to understand the background to the theory we have to look at how theories of gravitation developed.
		In 1907, two years after proposing the special theory of relativity, Einstein was preparing a review of special relativity when he suddenly wondered how Newtonian gravitation would have to be modified to fit in with special relativity.
		A special case of Emmy Noether's theorem was written down by Weyl in 1917 when he derived from it identities which, it was later realised, had been independently discovered by Ricci in 1889 and by Bianchi (a pupil of Klein) in 1902.

	The Special Theory of Relativity and Theories of Divine Eternity
		The special principle of relativity forbids us to regard the aether as composed of particles, the movements of which can be followed out through time, but the aether hypothesis as such is not incompatible with the special theory of relativity.
		Leftow's appeal to STR to ground this relation, it seems to me, evinces a certain naiveté concerning the philosophical foundations of the received physical interpretation of Relativity Theory and an uncritical acceptance of that interpretation, which is then (mis)applied to metaphysics.
		The consequence of motion relative to the fundamental frame will be certain anisotropy effects produced by dynamical causes operating on the moving systems, primarily length contraction in the direction of motion in order that the internal equilibrium of the system might be maintained.

	Is the Special Theory of Relativity Wrong?
		These days it would appear that the Special Theory of Relativity was beyond any form of doubt however I have a theoretical proof that would strongly suggest that the theory is fundamentally flawed.
		However according to the Special Theory of Relativity because time slows down and length decreases with velocity, the measured velocity of the beam would still be c.
		Since the proof stated above clearly shows that the Special Theory of Relativity could never work, it must also be the case that a large part of the General Theory of Relativity is equally unsound since it is entirely based upon the Special Theory.

	The Physics Classroom
		One of the peculiar aspects of Einstein's theory of special relativity is that the length of objects moving at relativistic speeds undergo a contraction along the dimension of motion.
		An observer at rest (relative to the moving object) would observe the moving object to be shorter in length.
		The amount of contraction of the object is dependent upon the object's speed relative to the observer.

		Instead, we propose here a way to make the effort necessary to really understand the core of the theory more directly and deeply like theorician physicists do, according to the mathematical terms in which Special Relativity is involved as a base for further developments of mathematical physics.
		Then, between several mathematically equivalent presentations (translations) of a theory, based on various choices of forms of imagination to represent aspects of reality, the best one is the one which makes it possible to grasp this mathematical theory in the easiest or most effective way.

	Gravitation and the General Theory of Relativity
		The General Theory of Relativity was Einstein's stupendous effort to remove the restriction on Special Relativity that no accelerations (and therefore no forces) be present, so that he could apply his ideas to the gravitational force.
		General Relativity and Newton's gravitational theory make essentially identical predictions as long as the strength of the gravitational field is weak, which is our usual experience.
		The General Theory of Relativity predicts that light coming from a strong gravitational field should have its wavelength shifted to larger values (a redshift).

	Special Theory of Relativity
		The Special Theory of Relativity is constructed in accordance with two simple underlying principles.
		Thus two observers, moving relative to one another even at a speed of 160,000 km/sec (100,000 mi/sec), each measuring the velocity of the same ray of light, would both find it to be moving at 300,000 km/sec (186,000 mi/sec), and this apparently anomalous result was proved by the Michelson-Morley experiment.
		Einstein's theory was also verified by experiments on the velocity of light in moving water and on magnetic forces in moving substances.

		He made important contributions to the quantum theory, but increasingly he sought to extend the special theory of relativity to phenomena involving acceleration.
		The key to an elaboration emerged in 1907 with the principle of equivalence, in which gravitational acceleration was held a priori indistinguishable from acceleration caused by mechanical forces; gravitational mass was therefore identical with inertial mass.
		In it the gravitational field equations were covariant; that is, similar to Maxwell's equations, the field equations took the same form in all equivalent frames of reference.

		In 1905, Albert Einstein's special theory of relativity was published under the title: "On the Electrodynamics of Moving Bodies." (1) In it Einstein reasoned from two postulates to several necessary conclusions.
		The special theory of relativity generates other conclusions, but these few are sufficient to give the reader a taste of the beliefs which Einstein's theory obliges us to accept.
		Because the light’s path, addressed in Einstein’s theory, was not parallel to the Y or Z dimensions, those two dimensions were not imagined subject to the shriveling effect that Einstein spoke of in the quote above.

		His major contribution to science was the special and the general theory of relativity, which gave a new dimension to that we call today "Modern Physics".
		Many people feel frustrated because when they try to understand relativity, they find some authors that expound in their books a complex arrangement of equations referring to the mathematical part of the theory, namely, the books are accessible for people with certain levels of knowledge (that is the case of engineers, physicists, mathematicians, among others).
		The beauty of relativity (as opposed to QM and Strings) is that it IS accessible to us mere mortals and it IS a sensible and beautiful theory, once you strip away everything else and just think about.
