John Baez: "I realized I didn't have enough confidence in either theory to engage in these heated debates. I also realized that there were other questions to work on: questions where I could actually tell when I was on the right track, questions where researchers cooperate more and fight less. So, I eventually decided to quit working on quantum gravity. It was very painful to do this, since quantum gravity had been my holy grail for decades. After you've convinced yourself that some problem is the one you want to spend your life working on, it's hard to change your mind. But when I finally did, it was tremendously liberating. I wouldn't urge anyone else to quit working on quantum gravity. Someday, someone is going to make real progress. When this happens, I may even rejoin the subject. But for now, I'm thinking about other things. And, I'm making more real progress understanding the universe than I ever did before." http://www.rehseis.cnrs.fr/recherche...ysique0708.htm Responsables : Nadine de Courntenay, Olivier Darrigol , Sara Franceschelli, Jan Lacki. "L'étonnante diversité des descriptions théoriques utilisées dans la physique d'hier et d'aujourd'hui a souvent été perçue comme une faiblesse temporaire qu'il faudrait corriger dans un état plus avancé de cette science. Dans cette veine, Pierre Duhem comparait le progrès scientifique à une marée montante dont les vagues ne sont qu'un décor périssable. Les penseurs réductionnistes cherchent à éliminer cette diversité en dérivant tout phénomène de l'ontologie homogène d'une théorie plus fondamentale que les autres. Les structuralistes et les positivistes, quant à eux, s'efforcent d'identifier les structures universelles qui dominent nos modes périssables de description. Contrairement à ces deux attitudes, les héritiers de James Clerk Maxwell, Ludwig Boltzmann et Henri Poincaré soulignent les vertus épistémiques d'une diversité des descriptions et considèrent que décrire est un acte dont la dynamique transcende les objets originels de la description. Dans ce séminaire, nous proposons d'adopter cette seconde attitude....." Pentcho Valev |

John Baez: "On the one hand we have the Standard Model, which tries to explain all the forces except gravity, and takes quantum mechanics into account. On the other hand we have General Relativity, which tries to explain gravity, and does not take quantum mechanics into account. Both theories seem to be more or less on the right track -- but until we somehow fit them together, or completely discard one or both, our picture of the world will be deeply schizophrenic." http://www.prospect-magazine.co.uk/a...ls.php?id=5538 Paul Davies: "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.edge.org/3rd_culture/smol...n03_print.html Lee Smolin: "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!" http://arxiv.org/PS_cache/arxiv/pdf/...705.4507v1.pdf Joao Magueijo and John W. Moffat: "The question is then: If Lorentz invariance is broken, what happens to the speed of light? Given that Lorentz invariance follows from two postulates -- (1) relativity of observers in inertial frames of reference and (2) constancy of the speed of light--it is clear that either or both of those principles must be violated." http://www.wired.com/wired/archive/1...ingtheory.html Lee Smolin: "Well, every string theory that's been written down says the speed of light is universal. But other ideas about quantum gravity predict the speed of light has actually increased. And an experiment on the Gamma Ray Large Area Space Telescope, launching next year, will check this. So I've said, look, if the speed of light isn't universal, that disconfirms string theory. But the string theorists say they could probably invent versions of the theory that work either way. We'd have to change our notion of what science is to accommodate this proposition. You just can't do science on that basis." http://cosmo.fis.fc.ul.pt/~crawford/...relativity.pdf John Stachel: "The idea that a light beam consisted of a stream of particles had been espoused by Newton and maintained its popularity into the middle of the 19th century. It was called the "emission theory" of light, a phrase I shall use...... The usual velocity addition law is then replaced by a new one, in which the velocity of light "added" to any other velocity ("added" in a new sense-it would be better to say "compounded with") does not increase, but stays the same! The Maxwell-Lorentz equations, when examined with the aid of this new kinematics, prove to take the same form in every inertial frame. They are, therefore, quite compatible with the relativity principle, which demands that the laws of electricity, magnetism and optics have this property. The presence or absence of an electric or magnetic field, is then also found to be relative to an inertial frame, allowing a completely satisfactory relativistic analysis of the example of the conducting wire loop and magnet in relative motion. Within six weeks of taking "the step," Einstein later recalled, he had worked out all of these consequences and submitted the 1905 SRT paper to Annalen der Physik. This does not imply that Lorentz's equations are adequate to explain all the features of light, of course. Einstein already knew they did not always correctly do so-in particular in the processes of its emission, absorption and its behavior in black body radiation. Indeed, his new velocity addition law is also compatible with an emission theory of light, just because the speed of light compounded with any lesser velocity still yields the same value. If we model a beam of light as a stream of particles, the two principles can still be obeyed. A few years later (1909), Einstein first publicly expressed the view that an adequate future theory of light would have to be some sort of fusion of the wave and emission theories. This is an example of how the special theory of relativity functioned as a theory of principle, limiting but not fixing the choice of a constructive theory of light." http://press.princeton.edu/chapters/i6272.html John Stachel: "Not only is the theory [of relativity] compatible with an emission theory of radiation, since it implies that the velocity of light is always the same relative to its source; the theory also requires that radiation transfer mass between an emitter and an absorber, reinforcing Einstein's light quantum hypothesis that radiation manifests a particulate structure under certain circumstances." http://ustl1.univ-lille1.fr/culture/...40/pgs/4_5.pdf Jean Eisenstaedt: "Il n'y a alors aucune raison theorique a ce que la vitesse de la lumiere ne depende pas de la vitesse de sa source ainsi que de celle de l'observateur terrestre ; plus clairement encore, il n'y a pas de raison, dans le cadre de la logique des Principia de Newton, pour que la lumiere se comporte autrement - quant a sa trajectoire - qu'une particule materielle. Il n'y a pas non plus de raison pour que la lumiere ne soit pas sensible a la gravitation. Bref, pourquoi ne pas appliquer a la lumiere toute la theorie newtonienne ? C'est en fait ce que font plusieurs astronomes, opticiens, philosophes de la nature a la fin du XVIIIeme siecle. Les resultats sont etonnants... et aujourd'hui nouveaux." Translation from French: "Therefore there is no theoretical reason why the speed of light should not depend on the speed of the source and the speed of the terrestrial observer as well; even more clearly, there is no reason, in the framework of the logic of Newton's Principia, why light should behave, as far as its trajectory is concerned, differently from a material particle. Neither is there any reason why light should not be sensible to gravitation. Briefly, why don't we apply the whole Newtonian theory to light? In fact, that is what many astronomers, opticians, philosophers of nature did by the end of 18th century. The results are surprising....and new nowadays." Pentcho Valev |

Fattest rats are also trying to leave the sinking ship:
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.....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.....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.thewest.com.au/default.as...ontentID=52711 "Professor Stephen Hawking says he is involved in work which "with luck" will answer "some of the ultimate questions". Much of the work is centred at Cambridge University's new Centre for Theoretical Cosmology. (....) "We are now working on the unification of Einstein's General Theory of Relativity, which governs the large-scale structure of the universe, with Quantum Theory, the theory of the very small. "This unification should determine what happened in the Big Bang and how the universe began." He added: "The centre will work to develop theories of the universe which are both mathematically consistent and observationally testable. "IT WILL BUILD ON A TRADITION DATING BACK TO ISAAC NEWTON OVER THREE CENTURIES AGO." http://www.telegraph.co.uk/connected...6/ecrein26.xml Martin Rees: "Einstein's great work was over well before he was 40. Photos from that time show him as a nattily dressed young professor, though we're more familiar with the image of the old Einstein - the benign and unkempt sage of poster and T-shirt. But Einstein didn't rest on his laurels in old age: he worked till his dying day seeking a unified theory of nature's forces. At that time it was, we now realise, a premature quest which was doomed from the start. Cynics have said that Einstein might as well have gone fishing from 1920 onwards. Although there's something rather noble about the way he persevered in his attempts to reach far beyond his grasp, in some respects the EINSTEIN CULT SENDS THE WRONG SIGNAL. It unduly exalts "armchair theory", which by itself would achieve little." Pentcho Valev |

Yawn. What you write above is the norm - all physics theories in history eventually went through replacement by something else. Why do you act as if relativity was meant to be different? Why do you act as if physicists thought relativity would be different? Grow up. -- Jan Bielawski |

Other signals carefully sent by fat rats:
http://discovermagazine.com/2004/sep...ns-lonely-path Lee Smolin: "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. He rejected his own theory, even before most physicists had come to accept it, for reasons that only he cared about. For another 10 years, as others in the world of physics slowly absorbed special relativity, Einstein pursued a lonely path away from it. Why? The main reason..... A second reason was his concern with incorporating gravity, making use of what he called the equivalence principle, which postulates that observers can never distinguish the effects of gravity from those of acceleration as long as they observe phenomena only in their neighborhood." http://www.blazelabs.com/f-g-gcont.asp "The first confirmation of a long range variation in the speed of light travelling in space came in 1964. Irwin Shapiro, it seems, was the first to make use of a previously forgotten facet of general relativity theory -- that the speed of light is reduced when it passes through a gravitational field....Faced with this evidence, Einstein stated:"In the second place our result shows that, according to the general theory of relativity, the law of the constancy of the velocity of light in vacuo, which constitutes one of the two fundamental assumptions in the special theory of relativity and to which we have already frequently referred, cannot claim any unlimited validity. A curvature of rays of light can only take place when the velocity of propagation of light varies with position."......Today we find that since the Special Theory of Relativity unfortunately became part of the so called mainstream science, it is considered a sacrilege to even suggest that the speed of light be anything other than a constant. This is somewhat surprising since even Einstein himself suggested in a paper "On the Influence of Gravitation on the Propagation of Light," Annalen der Physik, 35, 1911, that the speed of light might vary with the gravitational potential. Indeed, the variation of the speed of light in a vacuum or space is explicitly shown in Einstein's calculation for the angle at which light should bend upon the influence of gravity. One can find his calculation in his paper. The result is c'=c(1+V/c^2) where V is the gravitational potential relative to the point where the measurement is taken. 1+V/c^2 is also known as the GRAVITATIONAL REDSHIFT FACTOR." http://www.pitt.edu/~jdnorton/papers...UP_TimesNR.pdf "What Can We Learn about the Ontology of Space and Time from the Theory of Relativity?", John D. 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. ALREADY IN 1907, A MERE TWO YEARS AFTER THE COMPLETION OF THE SPECIAL THEORY, HE HAD CONCLUDED THAT THE SPEED OF LIGHT IS VARIABLE IN THE PRESENCE OF A GRAVITATIONAL FIELD." http://www.amazon.com/Relativity-Its.../dp/0486406768 "Relativity and Its Roots" by Banesh Hoffmann, Chapter 5. (I do not have the text in English so I am giving it in French) Banesh Hoffmann, "La relativite, histoire d'une grande idee", Pour la Science, Paris, 1999, p. 112: "De plus, si l'on admet que la lumiere est constituee de particules, comme Einstein l'avait suggere dans son premier article, 13 semaines plus tot, le second principe parait absurde: une pierre jetee d'un train qui roule tres vite fait bien plus de degats que si on la jette d'un train a l'arret. Or, d'apres Einstein, la vitesse d'une certaine particule ne serait pas independante du mouvement du corps qui l'emet! Si nous considerons que la lumiere est composee de particules qui obeissent aux lois de Newton, ces particules se conformeront a la relativite newtonienne. Dans ce cas, il n'est pas necessaire de recourir a la contraction des longueurs, au temps local ou a la transformation de Lorentz pour expliquer l'echec de l'experience de Michelson-Morley. Einstein, comme nous l'avons vu, resista cependant a la tentation d'expliquer ces echecs a l'aide des idees newtoniennes, simples et familieres. Il introduisit son second postulat, plus ou moins evident lorsqu'on pensait en termes d'ondes dans l'ether." Translation from French: "Moreover, if one admits that light consists of particles, as Einstein had suggested in his first paper, 13 weeks earlier, the second principle seems absurd: a stone thrown from a fast-moving train causes much more damage than one thrown from a train at rest. Now, according to Einstein, the speed of a particle would not be independent of the state of motion of the emitting body! If we consider light as composed of particles that obey Newton's laws, those particles would conform to Newtonian relativity. In this case, it is not necessary to resort to length contration, local time and Lorentz transformations in explaining the negative result of the Michelson-Morley experiment. Einstein however, as we have seen, resisted the temptation to explain the negative result in terms of Newton's ideas, simple and familiar. He introduced his second postulate, more or less evident as one thinks in terms of waves in aether." http://philsci-archive.pitt.edu/arch.../02/Norton.pdf John Norton: "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......THE MICHELSON-MORLEY EXPERIMENT IS FULLY COMPATIBLE WITH AN EMISSION THEORY OF LIGHT THAT CONTRADICTS THE LIGHT POSTULATE." http://philsci-archive.pitt.edu/arch.../02/Norton.pdf John Norton: ""The principle of relativity, if implemented in Galilean kinematics, dictated that the modified theory must embody an emission theory of light. We know that Einstein entertained such a theory.....Einstein leveled objections against all theories of this type. Some were technical complications. The most fundamental, however, was that these EMISSION THEORIES ADMITTED NO FIELD THEORY." http://www.perimeterinstitute.ca/pdf...09145525ca.pdf John Stachel: "It is not so well known that there was "another Einstein," who from 1916 on was skeptical about the continuum as a foundational element in physics..." The other 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." Pentcho Valev |

In Big Brother world 2+2=4 is replaced by 2+2=5, in Einstein zombie world the true equation c'=c+v given by Newton's emission theory of light is replaced by Einstein's 1905 false light postulate (c'=c): http://www.online-literature.com/orwell/1984/ George Orwell "1984": "In the end the Party would announce that two and two made five, and you would have to believe it. It was inevitable that they should make that claim sooner or later: the logic of their position demanded it. Not merely the validity of experience, but the very existence of external reality, was tacitly denied by their philosophy. The heresy of heresies was common sense. And what was terrifying was not that they would kill you for thinking otherwise, but that they might be right. For, after all, how do we know that two and two make four? Or that the force of gravity works? Or that the past is unchangeable? If both the past and the external world exist only in the mind, and if the mind itself is controllable what then?" http://www.ekkehard-friebe.de/wallace.htm Bryan Wallace: "Einstein's special relativity theory with his second postulate that the speed of light in space is constant is the linchpin that holds the whole range of modern physics theories together. Shatter this postulate, and modern physics becomes an elaborate farce!....The speed of light is c+v." Therefore in both worlds any theorizing can only be harmful (serve as camouflage) if two and two continue to make five and if the speed of photons continues to be independent of the speed of the light source.

As a comedian I had metaphysically deployed the conversation of energy with the other fruitless thoughts. The comedy aspect was CLEARLY driven, propelled and propagated by the dishonesty of it's victims. I hereby proudly announce how I still don't know the basics of physics. But the odds are not zero for me to detect dishonesty when it tries to con me. It seems to me that even Newton missed the obvious. He had loadstone's didn't he? Why didn't he build a perpetual motion device? After all his failure he probably became dishonest about it. It's more like the rule as the exception. I wouldn't know where to begin 'n explain even if anyone was interested. The order of things is just totally wrong. Lets try... One should evolve a theory around an observation in stead of evolving observations around theories. Engineering should be the source of unknown effects. Here it instantaneously it becomes clear how the experiment is unavailable for pet theory propaganda. One does not apply an experiment to a theory. Things just don't work like that. The experiment MAY have real world application. The denial of real world application is the denial of one's own use. Like a gigantic team of software developers coding a trillion dollar pixel accelerator. jajajajajjaja If we know how fast the pixel moves across the screen then we can calculate the speed of dumb. Which is inverse proportional with the rate of accomplishments. HAHAHAHAHAHAAHAHAA ok ok, say we have an electric chair on a stage. At the left of the chair we have a gigantic battery that is fully charged. At the right we have an empty battery. We put the first skeptic on the chair. We hook the negative terminals of the batteries up to another. The positive terminals go to the chair. We pull the lever and the electricity flows from the battery at the left to the one at the right. We keep electrocuting skeptics until the difference is gone. We now add one more empty battery. Ok we hook up the chair with the half full batteries in series and we discharge those into the empty one. More skeptics go up in smoke. We can now fry 6 times as much brainless morons using the same gradient. If we would replace the chair with an electric motor we could charge additional batteries with the back emf. If we would use bursts of pulses we would also be able to get some radiant energy action going on. The extra battery charges faster as the source can displace it's potential. It'zz nut geuing anywhere. lolzzz lets spin some electrostatic thingy all'zo lolzzz !! Then when teh miztifying apparatuzz zpinnzz we may utilize the gravitational ozialtionzzz all'zo. Thats how funny physics is. I can see the headlines already: "Comedian strikes gold." anyway, have a nice day. :-) http://blog.360.yahoo.com/factuurexpress http://magnetmotor.go-here.nl http://fototour.blogspot.com http://wind-car.go-here.nl |
