The Ideology of Relativity: The Case of the Clock Paradox Author: Peter Hayes Published in: Social Epistemology, Volume 23, Issue 1 January 2009 , pages 57 - 78 "Even well established members of the scientific community can ill afford to point to elementary (as opposed to recondite) problems with the theory. When, in the 1950s and 1960s, Professor Herbert Dingle ventured to argue that relativity theory left obvious inconsistencies unresolved, he found that his status as a respected exponent of the special theory changed rapidly into that of a near pariah. When Professor Paul Marmet, a former President of the Canadian Association of Physicists, ventured to make criticisms and call for a return to Newtonian principles, first his funding was cut off and then, in 1999, he was subject to constructive dismissal from his academic post and his experimental apparatus destroyed.7 From a career perspective, the only safe course for a sceptic within the physics profession is to adopt a prudent silence and to busy himself or herself with other fields of work." No shame, Dr. Rees? Pentcho Valev wrote: Open Letter to: Martin Rees, President of the Royal Society Copy to: Athene Donald FRS, Laurence Eaves Lancashire-Spencer Professor of Physics, Prof John Peacock, Martin Taylor FRS, Lorna Casselton FRS Dear Dr. Rees, Ninety years ago the Royal Society found it suitable to bury definitively the antithesis of Einstein's 1905 light postulate - the equation c'=c+v given by Newton's emission theory of light (v is the speed of the light source relative to the observer) - although even then informed scientists including Einstein knew this particular prediction of the emission theory was correct. Since then a schizophrenic atmosphere has been established where informed scientists often hint at and even extract profit from the correct equation c'=c+v (see examples of guilty conscience below) while ordinary mortals are forced to learn by rote the absurd consequences of Einstein's 1905 false light postulate. I think it is time for YOU to OFFICIALLY restore the truth. I will post this Open Letter on a few internet forums. Pentcho Valev Examples of guilty conscience: http://www.freerepublic.com/focus/f-news/519406/posts "A GROUP of astronomers and cosmologists has warned that the laws thought to govern the universe, including Albert Einstein's theory of relativity, must be rewritten. The group, which includes Professor Stephen Hawking and Sir Martin Rees, the astronomer royal, say such laws may only work for our universe but not in others that are now also thought to exist. "It is becoming increasingly likely that the rules we had thought were fundamental through time and space are actually just bylaws for our bit of it," said Rees, whose new book, Our Cosmic Habitat, is published next month. "Creation is emerging as even stranger than we thought." Among the ideas facing revision is Einstein's belief that the speed of light must always be the same - 186,000 miles a second in a vacuum. There is growing evidence that light moved much faster during the early stages of our universe. Rees, Hawking and others are so concerned at the impact of such ideas that they recently organised a private conference in Cambridge for more than 30 leading cosmologists." http://www.prospect-magazine.co.uk/a...ls.php?id=5538 Paul Davies: "Was Einstein wrong? Einstein's famous equation E=mc2 is the only scientific formula known to just about everyone. The "c" here stands for the speed of light. It is one of the most fundamental of the basic constants of physics. Or is it? In recent years a few maverick scientists have claimed that the speed of light might not be constant at all. Shock, horror! Does this mean the next Great Revolution in Science is just around the corner?" http://www.logosjournal.com/issue_4.3/smolin.htm Lee Smolin: "Quantum theory was not the only theory that bothered Einstein. Few people have appreciated how dissatisfied he was with his own theories of relativity. Special relativity grew out of Einstein's insight that the laws of electromagnetism cannot depend on relative motion and that the speed of light therefore must be always the same, no matter how the source or the observer moves. Among the consequences of that theory are that energy and mass are equivalent (the now- legendary relationship E = mc2) and that time and distance are relative, not absolute. SPECIAL RELATIVITY WAS THE RESULT OF 10 YEARS OF INTELLECTUAL STRUGGLE, YET EINSTEIN HAD CONVINCED HIMSELF IT WAS WRONG WITHIN TWO YEARS OF PUBLISHING IT." Joao Magueijo, PLUS VITE QUE LA LUMIERE, Dunod, 2003, pp. 298-299: "La racine du mal etait clairement la relativite restreinte. Tous ces paradoxes resultaient d'effets bien connus comme la contraction des longueurs, la dilatation du temps, ou E=mc^2, tous des predictions directes de la relativite restreinte. (...)

Norton: "In general relativity there is no comparable sense of the constancy of the speed of light. The constancy of the speed of light is a consequence of the perfect homogeneity of spacetime presumed in special relativity. There is a special velocity at each event; homogeneity forces it to be the same velocity everywhere. We lose that homogeneity in the transition to general relativity and with it we lose the constancy of the speed of light. Such was Einstein's conclusion at the earliest moments of his preparation for general relativity.

For this reason, I believe that the next phase in the development of theoretical physics will bring us a theory of light that can be considered a fusion of the oscillation and emission theories. The purpose of the following remarks is to justify this belief and to show that a profound change in our views on the composition and essence of light is imperative.....Then the electromagnetic fields that make up light no longer appear as a state of a hypothetical medium, but rather as independent entities that the light source gives off, just as in Newton's emission theory of light......Relativity theory has changed our views on light. Light is conceived not as a manifestation of the state of some hypothetical medium, but rather as an independent entity like matter. Moreover, this theory shares with the corpuscular theory of light the unusual property that light carries inertial mass from the emitting to the absorbing object." http://books.google.com/books?id=JokgnS1JtmMC "Relativity and Its Roots" By Banesh Hoffmann p.92: "Moreover, if light consists of particles, as Einstein had suggested in his paper submitted just thirteen weeks before this one, the second principle seems absurd: A stone thrown from a speeding train can do far more damage than one thrown from a train at rest; the speed of the particle is not independent of the motion of the object emitting it. And if we take light to consist of particles and assume that these particles obey Newton's laws, they will conform to Newtonian relativity and thus automatically account for the null result of the Michelson-Morley experiment without recourse to contracting lengths, local time, or Lorentz transformations. Yet, as we have seen, Einstein resisted the temptation to account for the null result in terms of particles of light and simple, familiar Newtonian ideas, and introduced as his second postulate something that was more or less obvious when thought of in terms of waves in an ether." http://www.physlink.com/Education/AskExperts/ae13.cfm "So, it is absolutely true that the speed of light is not constant in a gravitational field [which, by the equivalence principle, applies as well to accelerating (non-inertial) frames of reference]. If this were not so, there would be no bending of light by the gravitational field of stars....Indeed, this is exactly how Einstein did the calculation in: 'On the Influence of Gravitation on the Propagation of Light,' Annalen der Physik, 35, 1911. which predated the full formal development of general relativity by about four years. This paper is widely available in English. You can find a copy beginning on page 99 of the Dover book 'The Principle of Relativity.' You will find in section 3 of that paper, Einstein's derivation of the (variable) speed of light in a gravitational potential, eqn (3). The result is c' = c0 ( 1 + V / c^2 ) where V is the gravitational potential relative to the point where the speed of light c0 is measured." http://www.fqxi.org/data/articles/Se...lden_Spike.pdf "Loop quantum gravity also makes the heretical prediction that the speed of light depends on its frequency. That prediction violates special relativity, Einstein's rule that light in a vacuum travels at a constant speed for all observers..." http://www.edge.org/3rd_culture/smol...n03_print.html Lee Smolin: "Now, here is the really interesting part: Some of the effects predicted by the theory appear to be in conflict with one of the principles of Einstein's special theory of relativity, the theory that says that the speed of light is a universal constant. It's the same for all photons, and it is independent of the motion of the sender or observer. How is this possible, if that theory is itself based on the principles of relativity? The principle of the constancy of the speed of light is part of special relativity, but we quantized Einstein's general theory of relativity.....But there is another possibility. This is that the principle of relativity is preserved, but Einstein's special theory of relativity requires modification so as to allow photons to have a speed that depends on energy. The most shocking thing I have learned in the last year is that this is a real possibility. A photon can have an energy-dependent speed without violating the principle of relativity! This was understood a few years ago by Amelino Camelia. I got involved in this issue through work I did with Joao Magueijo, a very talented young cosmologist at Imperial College, London. During the two years I spent working there, Joao kept coming to me and bugging me with this problem.....These ideas all seemed crazy to me, and for a long time I didn't get it. I was sure it was wrong! But Joao kept bugging me and slowly I realized that they had a point. We have since written several papers together showing how Einstein's postulates may be modified to give a new version of special relativity in which the speed of light can depend on energy." http://query.nytimes.com/gst/fullpag...pagewanted=all "As propounded by Einstein as an audaciously confident young patent clerk in 1905, relativity declares that the laws of physics, and in particular the speed of light -- 186,000 miles per second -- are the same no matter where you are or how fast you are moving. Generations of students and philosophers have struggled with the paradoxical consequences of Einstein's deceptively simple notion, which underlies all of modern physics and technology, wrestling with clocks that speed up and slow down, yardsticks that contract and expand and bad jokes using the word "relative."......"Perhaps relativity is too restrictive for what we need in quantum gravity," Dr. Magueijo said. "We need to drop a postulate, perhaps the constancy of the speed of light." http://www.mfo.de/programme/schedule...WR_2006_10.pdf Jean Eisenstaedt: "At the end of the 18th century, a natural extension of Newton's dynamics to light was developed but immediately forgotten. A body of works completed the Principia with a relativistic optics of moving bodies, the discovery of the Doppler-Fizeau effect some sixty years before Doppler, and many other effects and ideas which represent a fascinating preamble to Einstein relativities. It was simply supposed that 'a body-light', as Newton named it, was subject to the whole dynamics of the Principia in much the same way as were material particles; thus it was subject to the Galilean relativity and its velocity was supposed to be variable. Of course it was subject to the short range 'refringent' force of the corpuscular theory of light -- which is part of the Principia-- but also to the long range force of gravitation which induces Newton's theory of gravitation. The fact that the 'mass' of a corpuscle of light was not known did not constitute a problem since it does not appear in the Newtonian (or Einsteinian) equations of motion. It was precisely what John Michell (1724-1793), Robert Blair (1748-1828), Johann G. von Soldner (1776-1833) and Fran¸cois Arago (1786-1853) were to do at the end of the 18th century and the beginning the 19th century in the context of Newton's dynamics. Actually this 'completed' Newtonian theory of light and material corpuscle seems to have been implicitly accepted at the time. In such a Newtonian context, not only Soldner's calculation of the deviation of light in a gravitational field was understood, but also dark bodies (cousins of black holes). A natural (Galilean and thus relativistic) optics of moving bodies was also developed which easily explained aberration and implied as well the essence of what we call today the Doppler effect. Moreover, at the same time the structure of -- but also the questions raised by-- the Michelson experiment was understood. Most of this corpus has long been forgotten. The Michell-Blair-Arago effect, prior to Doppler's effect, is entirely unknown to physicists and historians. As to the influence of gravitation on light, the story was very superficially known but had never been studied in any detail. Moreover, the existence of a theory dealing with light, relativity and gravitation, embedded in Newton's Principia was completely ignored by physicists and by historians as well. But it was a simple and natural way to deal with the question of light, relativity (and gravitation) in a Newtonian context. EINSTEIN HIMSELF DID NOT KNOW OF THIS NEWTONIAN THEORY OF LIGHT AND HE DID NOT RELY ON IT IN HIS OWN RESEARCH." http://www.perimeterinstitute.ca/ind...ecture_id=3576 John Stachel: "Einstein discussed the other side of the particle-field dualism - get rid of fields and just have particles." Albert Einstein: "I consider it entirely possible that physics cannot be based upon the field concept, that is on continuous structures. Then nothing will remain of my whole castle in the air, including the theory of gravitation, but also nothing of the rest of contemporary physics." John Stachel's comment: "If I go down, everything goes down, ha ha, hm, ha ha ha." |

Stephen Hawking: "Einsteins prediction of light deflection could not be tested immediately in 1915, because the First World War was in progress, and it was not until 1919 that a British expedition, observing an eclipse from West Africa, showed that light was indeed deflected by the sun, just as predicted by the theory. This proof of a German theory by British scientists was hailed as a great act of reconciliation between the two countries after the war. It is ionic, therefore, that later examination of the photographs taken on that expedition showed the errors were as great as the effect they were trying to measure. Their measurement had been sheer luck, or a case of knowing the result they wanted to get, not an uncommon occurrence in science." http://www.cieletespace.fr/evenement...taient-fausses "Relativité: les preuves étaient fausses.....Le monde entier a cru pendant plus de cinquante ans à une théorie non vérifiée. Car, nous le savons aujourdhui, les premières preuves, issues notamment dune célèbre éclipse de 1919, nen étaient pas. Elles reposaient en partie sur des manipulations peu avouables visant à obtenir un résultat connu à lavance, et sur des mesures entachées dincertitudes, quand il ne sagissait pas de fraudes caractérisées." http://www.cieletespaceradio.fr/inde...-la-relativite "Au début du XXème siècle, des scientifiques comme le Britannique Arthur Eddington avaient tant à coeur de vérifier la théorie de la relativité qu'ils ont tout mis en oeuvre pour que leurs expériences soient probantes." (ECOUTEZ!) http://discovermagazine.com/2008/mar...out-relativity "The eclipse experiment finally happened in 1919 (youre looking at it on this very page). Eminent British physicist Arthur Eddington declared general relativity a success, catapulting Einstein into fame and onto coffee mugs. In retrospect, it seems that Eddington fudged the results, throwing out photos that showed the wrong outcome. No wonder nobody noticed: At the time of Einsteins death in 1955, scientists still had almost no evidence of general relativity in action." http://www.newscientist.com/article/...to-albert.html New Scientist: Ode to Albert "Enter another piece of luck for Einstein. We now know that the light- bending effect was actually too small for Eddington to have discerned at that time. Had Eddington not been so receptive to Einstein's theory, he might not have reached such strong conclusions so soon, and the world would have had to wait for more accurate eclipse measurements to confirm general relativity."
