John Norton is the only Einsteinian who can decipher Einstein's 1954 confession: http://www.perimeterinstitute.ca/index.php?option=com_content&task=view&id=317&Itemid=81&lecture_id=3576 John Stachel: "Einstein discussed the other side of the particle-field dualism - get rid of fields and just have particles." Einstein's 1954 confession: "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." http://www.pitt.edu/~jdnorton/papers/companion.doc John Norton: "Einstein could not see how to formulate a fully relativistic electrodynamics merely using his new device of field transformations. So he considered the possibility of modifying Maxwell's electrodynamics in order to bring it into accord with an emission theory of light, such as Newton had originally conceived. There was some inevitability in these attempts, as long as he held to classical (Galilean) kinematics. Imagine that some emitter sends out a light beam at c. According to this kinematics, an observer who moves past at v in the opposite direction, will see the emitter moving at v and the light emitted at c+v. This last fact is the defining characteristic of an emission theory of light: the velocity of the emitter is added vectorially to the velocity of light emitted....If an emission theory can be formulated as a field theory, it would seem to be unable to determine the future course of processes from their state in the present. AS LONG AS EINSTEIN EXPECTED A VIABLE THEORY LIGHT, ELECTRICITY AND MAGNETISM TO BE A FIELD THEORY, these sorts of objections would render an EMISSION THEORY OF LIGHT INADMISSIBLE." Clearly John Stachel's reaction is just panic and hysteria but John Norton, the cleverest Einsteinian, knows the truth. Given Norton's analysis Einstein's 1954 confession can be modified in the following way: Einstein's 1954 confession (modified): "I consider it entirely possible that physics cannot be based upon my [Einstein's] 1905 false light postulate. 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." More recent evidence that John Norton, the cleverest Einsteinian, does know the truth: http://www.newscientist.com/article/mg20026831.500-what-makes-the-universe-tick.html "General relativity knits together space, time and gravity. Confounding all common sense, how time passes in Einstein's universe depends on what you are doing and where you are. Clocks run faster when the pull of gravity is weaker, so if you live up a skyscraper you age ever so slightly faster than you would if you lived on the ground floor, where Earth's gravitational tug is stronger. "General relativity completely changed our understanding of time," says Carlo Rovelli, a theoretical physicist at the University of the Mediterranean in Marseille, France.....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." Evidence that all clever Einsteinians now know the truth: http://www.amazon.com/Relativity-Simultaneity-Routledge-Contemporary-Philosophy/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, on the centenary of Albert Einsteins Special Theory of Relativity, come together in this volume 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 Relativitys relativistic concept of time in terms of epistemology, metaphysics and physics. There is no other book like this available; hence philosophers and scientists across the world will welcome its publication." "UNFORTUNATELY FOR EINSTEIN'S SPECIAL RELATIVITY, HOWEVER, ITS EPISTEMOLOGICAL AND ONTOLOGICAL ASSUMPTIONS ARE NOW SEEN TO BE QUESTIONABLE, UNJUSTIFIED, FALSE, PERHAPS EVEN ILLOGICAL." Craig Callender: "In my opinion, by far the best way for the tenser to respond to Putnam et al is to adopt the Lorentz 1915 interpretation of time dilation and Fitzgerald contraction. Lorentz attributed these effects (and hence the famous null results regarding an aether) to the Lorentz invariance of the dynamical laws governing matter and radiation, not to spacetime structure. On this view, Lorentz invariance is not a spacetime symmetry but a dynamical symmetry, and the special relativistic effects of dilation and contraction are not purely kinematical. The background spacetime is Newtonian or neo- Newtonian, not Minkowskian. Both Newtonian and neo-Newtonian spacetime include a global absolute simultaneity among their invariant structures (with Newtonian spacetime singling out one of neo-Newtonian spacetimes many preferred inertial frames as the rest frame). On this picture, there is no relativity of simultaneity and spacetime is uniquely decomposable into space and time." Pentcho Valev pvalev@yahoo.com
