EINSTEINIANA'S SCHIZOPHRENIC WORLD
1. Einsteinians (John Norton, Tom Roberts) admit that both the
Michelson-Morley and the Pound-Rebka experiments confirm Newton's emission theory of light, a theory postulating that the speed of light varies with v, the speed of the emitter relative to the observer, in accordance with the equation c'=c+v. This equation contradicts Einstein's 1905 constant-speed-of-light postulate: http://philsci-archive.pitt.edu/1743/2/Norton.pdf John Norton: "In addition to his work as editor of the Einstein papers in finding source material, Stachel assembled the many small clues that reveal Einstein's serious consideration of an emission theory of light; and he gave us the crucial insight that Einstein regarded the Michelson-Morley experiment as evidence for the principle of relativity, whereas later writers almost universally use it as support for the light postulate of special relativity. Even today, this point needs emphasis. The Michelson-Morley experiment is fully compatible with an emission theory of light that CONTRADICTS THE LIGHT POSTULATE." http://www.pitt.edu/~jdnorton/papers/companion.doc John Norton: "These efforts were long misled by an exaggeration of the importance of one experiment, the Michelson-Morley experiment, even though Einstein later had trouble recalling if he even knew of the experiment prior to his 1905 paper. This one experiment, in isolation, has little force. Its null result happened to be fully compatible with Newton's own emission theory of light. Located in the context of late 19th century electrodynamics when ether-based, wave theories of light predominated, however, it presented a serious problem that exercised the greatest theoretician of the day." http://groups.google.com/group/sci.p...abc7dbb30db6c2 John Norton: "THE MICHELSON-MORLEY EXPERIMENT IS FULLY COMPATIBLE WITH AN EMISSION THEORY OF LIGHT THAT CONTRADICTS THE LIGHT POSTULATE." Tom Roberts: "Sure. The fact that this one experiment is compatible with other theories does not refute relativity in any way. The full experimental record refutes most if not all emission theories, but not relativity." Pentcho Valev: "THE POUND-REBKA EXPERIMENT IS FULLY COMPATIBLE WITH AN EMISSION THEORY OF LIGHT THAT CONTRADICTS THE LIGHT POSTULATE." Tom Roberts: "Sure. But this experiment, too, does not refute relativity. The full experimental record refutes most if not all emission theories, but not relativity." 2. Einsteinians (John Norton, Craig Callender, Lee Smolin, Etienne Klein) reject the absurd consequences of Einstein's 1905 constant- speed-of-light postulate: http://www.newscientist.com/article/...erse-tick.html "It is still not clear who is right, says John Norton, a philosopher based at the University of Pittsburgh, Pennsylvania. Norton is hesitant to express it, but his instinct - and the consensus in physics - seems to be that space and time exist on their own. The trouble with this idea, though, is that it doesn't sit well with relativity, which describes space-time as a malleable fabric whose geometry can be changed by the gravity of stars, planets and matter." http://www.humanamente.eu/PDF/Issue13_Paper_Norton.pdf John Norton: "It is common to dismiss the passage of time as illusory since its passage has not been captured within modern physical theories. I argue that this is a mistake. Other than the awkward fact that it does not appear in our physics, there is no indication that the passage of time is an illusion. (...) The passage of time is a real, objective fact that obtains in the world independently of us. How, you may wonder, could we think anything else? One possibility is that we might think that the passage of time is some sort of illusion, an artifact of the peculiar way that our brains interact with the world. Indeed that is just what you might think if you have spent a lot of time reading modern physics. Following from the work of Einstein, Minkowski and many more, physics has given a wonderfully powerful conception of space and time. Relativity theory, in its most perspicacious form, melds space and time together to form a four- dimensional spacetime. The study of motion in space and all other processes that unfold in them merely reduce to the study of an odd sort of geometry that prevails in spacetime. In many ways, time turns out to be just like space. In this spacetime geometry, there are differences between space and time. But a difference that somehow captures the passage of time is not to be found. There is no passage of time." http://www.scientificamerican.com/ar...me-an-illusion Craig Callender in SCIENTIFIC AMERICAN: "Einstein mounted the next assault by doing away with the idea of absolute simultaneity. According to his special theory of relativity, what events are happening at the same time depends on how fast you are going. The true arena of events is not time or space, but their union: spacetime. Two observers moving at different velocities disagree on when and where an event occurs, but they agree on its spacetime location. Space and time are secondary concepts that, as mathematician Hermann Minkowski, who had been one of Einstein's university professors, famously declared, "are doomed to fade away into mere shadows." And things only get worse in 1915 with Einstein's general theory of relativity, which extends special relativity to situations where the force of gravity operates. Gravity distorts time, so that a second's passage here may not mean the same thing as a second's passage there. Only in rare cases is it possible to synchronize clocks and have them stay synchronized, even in principle. You cannot generally think of the world as unfolding, tick by tick, according to a single time parameter. In extreme situations, the world might not be carvable into instants of time at all. It then becomes impossible to say that an event happened before or after another." http://www.fqxi.org/community/articles/display/151 "The distinction between past, present and future is only a stubbornly persistent illusion." It was none other than Einstein who uttered these words. He was speaking about how our perception of time differs from the fundamental nature of time in physics. Take our perceptions first: We have a clear sense of the present moment, what came before, and what might come after. Unfortunately, physics treats time rather differently. Einstein's theory of special relativity presents us with a four-dimensional spacetime, in which the past, present and future are already mapped out. There is no special "now," just as there's no special "here." And just like spacetime does not have a fundamental direction - forcing us to move inexorably from east to west, say - time does not flow. "You have this big gap between the time of fundamental science and the time we experience," says Craig Callender, a philosopher at the University of California, San Diego. It's this gap that he has set out to narrow, using ideas from physics, evolutionary theory and cognitive science." http://www.fqxi.org/community/articles/display/148 "Many physicists argue that time is an illusion. Lee Smolin begs to differ. (...) Smolin wishes to hold on to the reality of time. But to do so, he must overcome a major hurdle: General and special relativity seem to imply the opposite. In the classical Newtonian view, physics operated according to the ticking of an invisible universal clock. But Einstein threw out that master clock when, in his theory of special relativity, he argued that no two events are truly simultaneous unless they are causally related. If simultaneity - the notion of "now" - is relative, the universal clock must be a fiction, and time itself a proxy for the movement and change of objects in the universe. Time is literally written out of the equation. Although he has spent much of his career exploring the facets of a "timeless" universe, Smolin has become convinced that this is "deeply wrong," he says. He now believes that time is more than just a useful approximation, that it is as real as our guts tell us it is - more real, in fact, than space itself. The notion of a "real and global time" is the starting hypothesis for Smolin's new work, which he will undertake this year with two graduate students supported by a $47,500 grant from FQXi." http://hps.master.univ-paris7.fr/cours_du_temps.doc Etienne Klein: "Aujourd'hui, L'astrophysicien Thibault Damour développe à sa manière des idées qui vont dans le même sens. Selon lui, le temps qui passe (qu'il sagisse d'un fait ou de notre sentiment) est le produit de notre seule subjectivité, un effet que nous devrions au caractère irréversible de notre mise en mémoire, de sorte que la question du cours du temps relèverait non pas de la physique, mais des sciences cognitives. Il écrit : « De même que la notion de température n'a aucun sens si l'on considère un système constitué d'un petit nombre de particules, de même il est probable que la notion d'écoulement du temps n'a de sens que pour certains systèmes complexes, qui évoluent hors de l'équilibre thermodynamique, et qui gèrent d'une certaine façon les informations accumulées dans leur mémoire. » Le temps ne serait donc qu'une apparence d'ordre psychologique : « Dans le domaine d'espace-temps que nous observons, poursuit-il, nous avons l'impression qu'il s'écoule "du bas vers le haut" de l'espace-temps, alors qu'en réalité ce dernier constitue un bloc rigide qui n'est nullement orienté a priori : il ne le devient que pour nous [35]. » L'existence même d'un « cours du temps », ou d'un « passage du temps », n'est ainsi que simple apparence pour de nombreux physiciens contemporains. Certains vont même jusqu'à considérer le passage du temps comme une pure illusion, comme un produit culturel abusivement dérivé de la métaphore du fleuve. C'est en effet la conception dite de l'« univers-bloc » qui semble avoir les faveurs d'une majorité de physiciens. Dans le droit fil de la théorie de la relativité, celle-ci consiste à invoquer un univers constitué dun continuum d'espace-temps à quatre dimensions, privé de tout flux temporel : tous les événements, qu'ils soient passés, présents et futurs, ont exactement la même réalité, de la même façon que différents lieux coexistent, en même temps et avec le même poids ontologique, dans l'espace. En d'autres termes, les notions de passé ou de futur ne sont que des notions relatives, comme celles d'Est et d'Ouest. En un sens, tout ce qui va exister existe déjà et tout ce qui a existé existe encore. L'espace-temps contient l'ensemble de l'histoire de la réalité comme la partition contient l'uvre musicale : la partition existe sous une forme statique, mais ce qu'elle contient, l'esprit humain l'appréhende généralement sous la forme d'un flux temporel." 3. Of all the Einsteinians not one could think of a reason why Einstein's 1905 constant-speed-of-light postulate should be questioned. Even if this postulate were false, Divine Albert's Divine Theory would be unaffected: http://o.castera.free.fr/pdf/bup.pdf Jean-Marc LÉVY-LEBLOND: "Maintenant il s'agit de savoir si le photon a vraiment une masse nulle. Pour un physicien, il est absolument impossible d'affirmer qu'une grandeur, quelle qu'elle soit, a rigoureusement la valeur zéro, pas plus d'ailleurs que n'importe quelle autre valeur. Tout ce que je sais de la masse du photon, c'est ce que disent mes collègues expérimentateurs : "Elle est très faible ! Inférieure, selon nos mesures actuelles, à 10^(-50)kg". Mais si demain, on découvre que cette masse est non-nulle, alors, le photon ne va pas à la vitesse de la lumière... Certes, il irait presque toujours à une vitesse tellement proche de la vitesse limite que nous ne verrions que difficilement la différence, mais conceptuellement, il pourrait exister des photons immobiles, et la différence est essentielle. Or, nous ne saurons évidemment jamais si la masse est rigoureusement nulle ; nous pourrons diminuer la borne supérieure, mais jamais l'annuler. Acceptons donc l'idée que la masse du photon est nulle, et que les photons vont à la vitesse limite, mais n'oublions pas que ce n'est pas une nécessité. Cela est important pour la raison suivante. Supposez que demain un expérimentateur soit capable de vraiment mettre la main sur le photon, et de dire qu'il n'a pas une masse nulle. Qu'il a une masse de, mettons 10^(-60)kg. Sa masse n'est pas nulle, et du coup la lumière ne va plus à la "vitesse de la lumière". Vous pouvez imaginer les gros titres dans les journaux : "La théorie de la relativité s'effondre", "Einstein s'est trompé", etc. Or cette éventuelle observation ne serait en rien contradictoire avec la théorie de la relativité ! Einstein a certe construit sa théorie en analysant des échanges de signaux lumineux propagés à la vitesse limite. Si on trouve que le photon a une masse non-nulle, ce sera que cette vitesse n'est pas la vitesse limite, et la démonstration initiale s'effondre donc. Mais ce n'est pas parce qu'une démonstration est erronée que son résultat est faux ! Quand vous avez une table à plusieurs pieds, vous pouvez en couper un, elle continue à tenir debout. Et heureusement, la théorie de la relativité a plusieurs pieds." http://o.castera.free.fr/pdf/Chronogeometrie.pdf Jean-Marc Lévy-Leblond "De la relativité à la chronogéométrie ou: Pour en finir avec le "second postulat" et autres fossiles": "D'autre part, nous savons aujourd'hui que l'invariance de la vitesse de la lumière est une conséquence de la nullité de la masse du photon. Mais, empiriquement, cette masse, aussi faible soit son actuelle borne supérieure expérimentale, ne peut et ne pourra jamais être considérée avec certitude comme rigoureusement nulle. Il se pourrait même que de futures mesures mettent en évidence une masse infime, mais non-nulle, du photon ; la lumière alors n'irait plus à la "vitesse de la lumière", ou, plus précisément, la vitesse de la lumière, désormais variable, ne s'identifierait plus à la vitesse limite invariante. Les procédures opérationnelles mises en jeu par le "second postulat" deviendraient caduques ipso facto. La théorie elle-même en serait-elle invalidée ? Heureusement, il n'en est rien ; mais, pour s'en assurer, il convient de la refonder sur des bases plus solides, et d'ailleurs plus économiques. En vérité, le premier postulat suffit, à la condition de l'exploiter à fond." http://www.hep.princeton.edu/~mcdona..._44_271_76.pdf Jean-Marc Levy-Leblond: "This is the point of view from wich I intend to criticize the overemphasized role of the speed of light in the foundations of the special relativity, and to propose an approach to these foundations that dispenses with the hypothesis of the invariance of c. (...) We believe that special relativity at the present time stands as a universal theory discribing the structure of a common space-time arena in which all fundamental processes take place. (...) The evidence of the nonzero mass of the photon would not, as such, shake in any way the validity of the special relalivity. It would, however, nullify all its derivations which are based on the invariance of the photon velocity." http://groups.google.ca/group/sci.ph...1ebdf49c012de2 Tom Roberts: "If it is ultimately discovered that the photon has a nonzero mass (i.e. light in vacuum does not travel at the invariant speed of the Lorentz transform), SR would be unaffected but both Maxwell's equations and QED would be refuted (or rather, their domains of applicability would be reduced)." http://www.amazon.com/Einsteins-Rela.../dp/9810238886 Jong-Ping Hsu: "The fundamentally new ideas of the first purpose are developed on the basis of the term paper of a Harvard physics undergraduate. They lead to an unexpected affirmative answer to the long-standing question of whether it is possible to construct a relativity theory without postulating the constancy of the speed of light and retaining only the first postulate of special relativity. This question was discussed in the early years following the discovery of special relativity by many physicists, including Ritz, Tolman, Kunz, Comstock and Pauli, all of whom obtained negative answers." http://www.newscientist.com/article/...elativity.html Why Einstein was wrong about relativity 29 October 2008, Mark Buchanan, NEW SCIENTIST "This "second postulate" is the source of all Einstein's eccentric physics of shrinking space and haywire clocks. And with a little further thought, it leads to the equivalence of mass and energy embodied in the iconic equation E = mc2. The argument is not about the physics, which countless experiments have confirmed. It is about whether we can reach the same conclusions without hoisting light onto its highly irregular pedestal. (...) But in fact, says Feigenbaum, both Galileo and Einstein missed a surprising subtlety in the maths - one that renders Einstein's second postulate superfluous. (...) The idea that Einstein's relativity has nothing to do with light could actually come in rather handy. For one thing, it rules out a nasty shock if anyone were ever to prove that photons, the particles of light, have mass. We know that the photon's mass is very small - less than 10-49 grams. A photon with any mass at all would imply that our understanding of electricity and magnetism is wrong, and that electric charge might not be conserved. That would be problem enough, but a massive photon would also spell deep trouble for the second postulate, as a photon with mass would not necessarily always travel at the same speed. Feigenbaum's work shows how, contrary to many physicists' beliefs, this need not be a problem for relativity." http://groups.google.com/group/sci.p...d3ebf3b94d89ad Tom Roberts: "As I said before, Special Relativity would not be affected by a non-zero photon mass, as Einstein's second postulate is not required in a modern derivation (using group theory one obtains three related theories, two of which are solidly refuted experimentally and the third is SR). So today's foundations of modern physics would not be threatened. http://arxiv.org/PS_cache/arxiv/pdf/...806.1234v1.pdf Mitchell J. Feigenbaum: "In this paper, not only do I show that the constant speed of light is unnecessary for the construction of the theories of relativity, but overwhelmingly more, there is no room for it in the theory. (...) We can make a few guesses. There is a "villain" in the story, who, of course, is Newton." Pentcho Valev |

Valev again contradicted by experience

There is a space-time vortex around Earth, and its shape precisely matches the predictions of Einstein's theory of gravity. Researchers confirmed these points at a press conference today at NASA headquarters where they announced the long-awaited results of Gravity Probe B (GP-B).

EINSTEINIANA'S SCHIZOPHRENIC WORLD
The only permitted development in Einsteiniana's schizophrenic world
(Einstein's 1905 false constant-speed-of-light postulate should remain intact): http://philsci-archive.pitt.edu/5339/ Lorentzian theories vs. Einsteinian special relativity - a logico- empiricist reconstruction Laszlo E. Szabo "It is widely believed that the principal difference between Einstein's special relativity and its contemporary rival Lorentz-type theories was that while the Lorentz-type theories were also capable of "explaining away" the null result of the Michelson-Morley experiment and other experimental findings by means of the distortions of moving measuring-rods and moving clocks, special relativity revealed more fundamental new facts about the geometry of space-time behind these phenomena. I shall argue that special relativity tells us nothing new about the geometry of space-time, in comparison with the pre- relativistic Galileo-invariant conceptions; it simply calls something else "space-time", and this something else has different properties. All statements of special relativity about those features of reality that correspond to the original meaning of the terms "space" and "time" are identical with the corresponding traditional pre- relativistic statements. It will be also argued that special relativity and Lorentz theory are completely identical in both senses, as theories about space-time and as theories about the behavior of moving physical objects." http://www.amazon.com/Relativity-Sim.../dp/0415701740 Einstein, Relativity and Absolute Simultaneity (Routledge Studies in Contemporary Philosophy) "It is remarkable that the Special Theory has thus far managed to survive largely unscathed the collapse of its essential epistemological underpinnings. One wonders how this can be so. Undoubtedly a major part of the answer is the understandable one that physicists are not epistemologists; physicists typically know no more about epistemology, the philosophy of language (e.g. problems with the verificationist criterion of semantic meaning), and ontology than philosophers typically know about physics. The precise philosophical arguments for the illogicality, falsity, or unjustifiably of the epistemological, semantic, and ontological presuppositions of the Special Theory remain, with a few exceptions, unknown among physicists. The price paid for the growth of knowledge is increased specialization, which, paradoxically, also prevents or reverses the growth of knowledge, since specialists in one field often base their work on premises that (unbeknownst to them) have been refuted or disconfirmed in another field. The only solution we can see for this problem is that the training or schooling of physicists ought to include schooling in philosophy (and, as we shall see, the converse should hold for philosophers). Perhaps this is most practicable in the form of there being thinkers who take as their specialization the intersection of physics and philosophy and the works of these thinkers, at least in "introductory formats", being a part of the education of both physicists and philosophers. If this proves unfeasible and the situation remains as it presently stands, the unpalatable situation may result that neither physicists nor philosophers are in a position to have adequately justified beliefs about space and time but only philosophers of physics (or the few thinkers who are both philosophers and physicists, such as David Albert and Bas Van Fraassen, and, from the side of physics, Niels Bohr and David Bohm, who developed philosophical theories in addition to physically interpreted equations). Apart from leaving unaddressed the epistemological and semantic presuppositions of STR, there is an even stronger factor behind physicists' unwillingness to abandon the Special Theory. The Special Theory is a part of orthodox quantum field theory (QFT) (quantum electrodynamics and quantum chromodynamics), which aims to unify the Special Theory with quantum mechanics. Physicists would be at a loss as to how to proceed if they rejected the Special Theory as unjustified, since they (for the most part) believe that this would require them to reject QFT. In the light of this dependence on Special Relativity, physicists are not likely to abandon it unless it is observationally disconfirmed and there is an observationally adequate theory available to replace it. In fact, there is a theory that is not merely observationally equivalent to the Special Theory, but also observationally superior to it, namely Lorentzian or neo-Lorentzian theory. Lorentz's theory is regarded by many physicists who have studied Lorentzian theory, such as J.S. Bell, to be observationally equivalent to the Special Theory. However a Lorentzian or neo-Lorentzian theory is, in fact, observationally superior to the Special Theory (a fact that Bell, surprisingly, did not point out), since a Lorentzian theory, in contrast to the Special Theory, is consistent with the relations of absolute, instantaneous simultaneity..." http://hps.elte.hu/PIRT.Budapest/ Mathematics, Physics and Philosophy In the Interpretations of Relativity Theory, Budapest 4-6 September 2009 "The objective of the conference is to discuss the mathematical, physical and philosophical elements in the physical interpretations of Relativity Theory (PIRT); the physical and philosophical arguments and commitments shaping those interpretations and the various applications of the theory, especially in relativistic cosmology and relativistic quantum theory. The organizing committee is open for discussion of recent advances in investigations of the mathematical, logical and conceptual structure of Relativity Theory, as well as for analysis of the cultural, ideological and philosophical factors that have roles in its evolution and in the development of the modern physical world view determined to a considerable extent by that theory. The conference intends to review the fruitfulness of orthodox Relativity, as developed from the Einstein-Minkowski formulation, and to suggest how history and philosophy of science clarify the relationship between the accepted relativistic formal structure and the various physical interpretations associated with it. While the organizing committee encourages critical investigations and welcomes both Einsteinian and non-Einsteinian (Lorentzian, etc.) approaches, including the recently proposed ether-type theories, it is assumed that the received formal structure of the theory is valid and anti-relativistic papers will not be accepted."

EINSTEINIANA'S SCHIZOPHRENIC WORLD
http://www.amazon.com/Relativity-Sim.../dp/0415701740
Einstein, Relativity and Absolute Simultaneity (Routledge Studies in Contemporary Philosophy) "Einstein, Relativity and Absolute Simultaneity is an anthology of original essays by an international team of leading philosophers and physicists who have come together to reassess the contemporary paradigm of the relativistic concept of time. A great deal has changed since 1905 when Einstein proposed his Special Theory of Relativity, and this book offers a fresh reassessment of Special Relativity's relativistic concept of time in terms of epistemology, metaphysics, and physics.(...) Unfortunately for Einstein's Special Theory, however, its epistemological and ontological assumptions are now seen to be questionable, unjustified, false, perhaps even illogical." In a world different from Einsteiniana's schizophrenic world criticizing a DEDUCTIVE theory in this way without even hinting at the possible falsehood of its two postulates would be a sign of ignorance or prejudice. In Einsteiniana's schizophrenic world intensive exercises in crimestop have converted the order given by Einsteiniana's priests: "Don't even think of the possible falsehood of Einstein's 1905 constant-speed-of-light postulate!" into an absolute principle. http://www.liferesearchuniversal.com...html#seventeen George Orwell: "Crimestop means the faculty of stopping short, as though by instinct, at the threshold of any dangerous thought. It includes the power of not grasping analogies, of failing to perceive logical errors, of misunderstanding the simplest arguments if they are inimical to Ingsoc, and of being bored or repelled by any train of thought which is capable of leading in a heretical direction. Crimestop, in short, means protective stupidity." Pentcho Valev |
