Space and Time in Special Relativity The special theory of relativity is the result of two postulates: The laws of physics are the same in all inertial reference frames. Extention from the Newtonian principle of relativity: the laws of mechanics are the same for all observers in uniform motion. The speed of light in empty space is the same for all inertial frames. The speed of an object depends on the reference frame, however the speed of light in space is the same. From the above two postulates, our understanding of space and time has to be modified. This java applet invites you to the world of space and time in special relativity. There are two devices that utilize photons to measure time differences (some kind of clock). A mirror will reflect the photon when it reaches the top or bottom of the device. First, press Start button to begin the animation. Both devices are synchronized. Two Light pulses emitted from the ends (yellow rings) reach the center of the device at the same time. There is no relative motion between the two devices. Now, change the relative velocity from the selections (

Proof of the Falsity of the Special Theory of Relativity A n example of a popular, but faulty derivation of the Lorentz or transformation equations, followed by a philosophical proof of the falsity of the special theory of relativity. © Erik J. Lange 1999 Last updated 28-5-2004 (D-M-Y) Short introduction Today (1999) the theory of relativity by Albert Einstein is still a generally accepted theory. Although there have been raised a number of objections against the theory since its first publication in 1905, none of these have been able to convince the scientific community of the falsity of the theory. On philosophical, mathematical and empirical grounds, there are nevertheless many valid objections against the theory to be found. This article focuses on two of these, in an analysis of a popular derivation of the Lorentz-transformation according to the theory of special relativity and by means of a philosophical argument showing a contradiction between the two postulates of special relativity. The purpose of Einstein's theory was to create a system of equations which would describe the transformation of coordinates from one reference-frame to another. Hereby the two reference-frames have a relative velocity

TABLE OF CONTENTS Introduction The Constancy of the Speed of Light The Michelson-Morley Experiment Einstein "Explains" the Michelson-Morley Experiment ... Conclusion INTRODUCTION In this document we discuss Einstein's Special Theory of Relativity. The treatment is non-mathematical, except for a brief use of Pythagoras' theorem about right triangles. We concentrate on the implications of the theory. The document is based on a discussion of the the theory for an upper-year liberal arts course in Physics without mathematics; in the context of that course the material here takes about 4 or 5 one-hour classes. Einstein published this theory in 1905. The word special here means that we restrict ourselves to observers in uniform relative motion. This is as opposed the his General Theory of Relativity of 1916; this theory considers observers in any state of uniform motion including relative acceleration. It turns out that the general theory is also a theory of gravitation. Sometimes one hears that the Special Theory of Relativity says that all motion is relative. This is not quite true. Galileo and Newton had a similar conception. Crucial to Newton's thinking is that there is an absolute space, independent of the things in that space:

A Note On Relativity I would like to point your attention towards some mistakes frequently made in established (special) relativity textbooks. One of the most popular ones will be a statement of the kind: "....A is running to meet the (light) signal pulse wheras C is running away from it." Strictly speaking this is wrong because this defies the second postulate. The principle of relativity doesn't apply to the relationship between observers and observables on the one hand and the propagation of light on the other. If it did,then it would be fair to say that an object can be regarded as traveling at the speed of light,with "light stationary". Therefore any object under consideration must be regarded as stationary with respect to the propagation of light, which means that it is not possible to "run to meet" a lightsignal.

Next: The Galilean Transformations STR - The Special Theory of Relativity Let's briefly recapitulate the situation in 1865: the Maxwell equations , which correctly described all the phenomena of electromagnetism known in the mid-19 th Century (and then some), predicted also that electromagnetic fields should satisfy the wave equation by virtue of a changing creating and vice versa , the electric and magnetic fields would be able to ``play off each other" and propagate through space in the form of a wave with all the properties of light (or its manifestations in shorter and longer wavelengths, which we also term ``light" when discussing electromagnetic waves in general). Fine, so far. But there are some unsettling implications of this ``final" explanation of light. First of all (and the focus of this handout) is the omission of any reference to a medium that does the ``wiggling" as the electromagnetic wave goes through it. Water waves propagate through water, sound waves through air, liquid or solid, plasma waves through plasmas, This was the first time anyone had ever postulated a wave that just propagated by itself through empty vacuum (or ``free space," as it is often called in this context). Moreover, the propagation velocity of light (or any electromagnetic wave) through the vacuum is given unambiguously by the

project d4 special relativity virtual relativity general relativity gallery publications ... contact special relativity introduction Einstein's theory of special relativity is widely regarded as a difficult and hardly comprehensible theory, even today - more than ninety years after its publication in 1905. One important reason for this is that the properties of space, time, and light in relativistic physics are totally different from those in classical, Newtonian physics. In many respects, they are contrary to human experience and everyday perception, which is based on low velocities. In the real world, mankind is limited to very small velocities compared to the speed of light. For example, the speed of light is a million times faster than the speed of an airplane and 40,000 times faster than the speed at which the Space Shuttle orbits the Earth. Even in the long term future, there is no hope of achieving velocities comparable to the speed of light. Therefore, computer simulations are the only means of visually exploring the realm of special relativity. They enable us to experience special relativistic phenomena such as Lorentz contraction, time dilation, aberration, and finite speed of light. Thus they can help to establish a more intuitive approach to special relativity. visualization techniques Today, there exist two well-known techniques for rendering of fast moving objects. The first is an extension of normal three-dimensional ray-tracing. The second is a relativistic extension of polygon-rendering.

The Special Relativity Theory Concepts, foundations and critical analysis. by: Marcelo A. Crotti First version ( in Spanish ) : Nov 6 th Last modification: Sep 05 th This page is not designed for amusement. But I hope it will be kind of entertainment to read it. Developing this topic, I am trying to contribute to the diffusion (from my own point of view) and general understanding of the concepts behind the special theory of relativity which, together with the quantum theory, redefined the physics and the philosophy of 20th century. In agreement with the time that I have invested to understand and to adapt the Special Theory of Relativity to my own way of thinking, the development of this page has taken me many months. The work is far from being finished, so, I will be indicating the date whenever I make changes or additions in the different subjects. This page is not directed to those making their first approach to the concepts of Special Relativity Theory (SRT). However, based on reiterated requirements, I have added a small introduction to relativity that embraces scientific and conceptual historical topics, intimately bound to the development of this theory. To obtain better benefits from the different developments and discussions it is convenient to know: The foundations of the Michelson-Morley experiment.

94. PART II - THE GENERAL THEORY OF RELATIVITY/SPECIAL AND GENERAL PRINCIPLE OF RELA Globusz Publishing. special AND GENERAL PRINCIPLE OF relativity. In this sense we speak of the special principle of relativity, or special theory of relativity. http://www.globusz.com/ebooks/Einstein/00000028.htm

G lobusz P ublishing SPECIAL AND GENERAL PRINCIPLE OF RELATIVITY The basal principle, which was the pivot of all our previous considerations, was the special principle of relativity, i.e. the principle of the physical relativity of all uniform motion. Let as once more analyse its meaning carefully. It was at all times clear that, from the point of view of the idea it conveys to us, every motion must be considered only as a relative motion. Returning to the illustration we have frequently used of the embankment and the railway carriage, we can express the fact of the motion here taking place in the following two forms, both of which are equally justifiable : (a) The carriage is in motion relative to the embankment, (b) The embankment is in motion relative to the carriage. In (a) the embankment, in (b) the carriage, serves as the body of reference in our statement of the motion taking place. If it is simply a question of detecting or of describing the motion involved, it is in principle immaterial to what reference-body we refer the motion. As already mentioned, this is self-evident, but it must not be confused with the much more comprehensive statement called "the principle of relativity," which we have taken as the basis of our investigations. The principle we have made use of not only maintains that we may equally well choose the carriage or the embankment as our reference-body for the description of any event (for this, too, is self-evident). Our principle rather asserts what follows : If we formulate the general laws of nature as they are obtained from experience, by making use of

Resources The Special Theory of Relativity and Theories of Divine Eternity William Lane Craig William Lane Craig is Research Professor of Philosophy at Talbot School of Theology in La Mirada, California. He lives in Atlanta, Georgia, with his wife Jan and their two teenage children Charity and John. At the age of sixteen as a junior in high school, he first heard the message of the Christian gospel and yielded his life to Christ. Dr. Craig pursued his undergraduate studies at Wheaton College (B.A. 1971) and graduate studies at Trinity Evangelical Divinity School (M.A. 1974; M.A. 1975), the University of Birmingham (England) (Ph.D. 1977), and the University of Munich (Germany) (D.Theol. 1984). From 1980-86 he taught Philosophy of Religion at Trinity, during which time he and Jan started their family. In 1987 they moved to Brussels, Belgium, where Dr. Craig pursued research at the University of Louvain until 1994. Contemporary analyses of divine eternity often make explicit appeal to to the Special Theory of Relativity in support of the doctrine of divine timelessness. For example, two fundamental tenets of Leftow's theory, namely, (i) that temporal things exist both in time and in timeless eternity and (ii) that the timeless presence of all things to God in eternity is compatible with objective temporal becoming, depend essentially upon the legitimacy of the application of Einsteinian relativity to temporal events in relation to God. I argue that the first of these rests upon category mistakes, presupposes a reductionist view of time, and seems incompatible with a tensed theory of time. The second involves the same conceptual mistakes, but also hinges upon a particular interpretation of STR which, though widespread, is by no means the most plausible.

Multimedia Physics Studio Einstein's Theory of Special Relativity Relativistic Length Contraction Einstein's Theory of Special Relativity Relativistic Length Contraction 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. That is to say, that an object at rest might have be measured to be 200 feet long; yet the same object when moving at relativistic speeds relative to the observer/measurer would have a measured length which is less than 200 ft. This phenomenon is not due to actual errors in measurement or faulty observations; the object is actually contracted in length as seen from the stationary reference frame . The amount of contraction of the object is dependent upon the object's speed relative to the observer. The animations below depict this phenomena of length contraction. In each animation a spaceship is moving past Earth at a high speed. The spaceship would be measured to be 200 feet in length when at rest relative to the observer.

Dimensions in special relativity Author: R.F.J. van Linden Version 1.47 (draft), May 2004. Introduction: You will find here an Euclidean interpretation of special relativity, parts of which are not unlike the many similar attempts that have already been made by both professional and amateur physicists to demystify its predictions about time dilation and length contraction. While this is often the sole purpose of the alternatives for the Einstein-Minkowski original, this version goes much deeper and uses it as the starting point for a potential entrance to unification of the four forces of nature and a promising way forward to direct manipulation of momentum without the need for propellant. The reader should be prepared to enter an Euclidean world that is perhaps even less intuitive than the classical Minkowski interpretation of special relativity. High demands are placed on imagination, in particular in multi-dimensional geometry and the interpretation and role of the time dimension. For readers with limited time, a

Astronomy SPECIAL RELATIVITY The purpose of special relativity is to provide a mathematical description of the observable properties of the universe. Those properties must be the same for any observer regardless of whether or not he is stationary or in motion. In special relativity, however, the motion of the observer is restricted to the special case of being uniform i.e. unaccelerated. If the observer is changing his velocity, there must be an external force acting upon him and this cannot be dealt with by special relativity. It was dealt with by Einstein in his general theory, however. There is no experiment in existence which can tell the person who is performing it what his absolute motion through space is. A person could conduct an experiment in the back of a lorry, moving with a constant velocity, and then re-perform the experiment in a laboratory and would get exactly the same results. There would be no way to determine from the results which experiment had been carried out where. The universality of the speed of light is the second guiding postulate of the special theory of relativity. It simply states the proven fact that the speed of light
