Hilton Ratcliffe: "I have colleagues who have been barred from observatories, had been refused publication, had research funding withdrawn, lost jobs and even been chased from their country of birth - all because they insisted on publicly announcing what they had seen in the heavens, which did not fit the preferred model. They have so much courage it makes my eyes water. They almost literally put their lives on the line. They are the Galileos of our time. (...) Theory would be more interesting if it were logical and comprehensible. In the case of mathematical theory, it is neither. There have been no new fundamental discoveries in physics for over half a century. Physics is dying, being suffocated by meta-mathematics, and physics departments at major universities with grand histories in physical science are closing down for lack of interest. (...) Professor Don Scott told me once, “The problems with cosmology and astrophysics in the modern era are not scientific so much as sociological.” The Big Bang Theory is a faith-based system. People believe it because they want to believe it, not because they have been convinced by the supporting data. When Einstein was ready to write down what was to become his General Theory of Relativity, he found that the mathematics required by such a concept were quite beyond him. He consequently engaged the services of his friend, mathematics professor Marcel Grossman, to construct the mathematical formalism. Grossman felt, for reasons we can only speculate, that the best way to achieve this was to use a new and arcane mathematical language called Differential Geometry. It is estimated that when GTR was published in 1915, only about a dozen specialist meta-mathematicians in the world could decipher the math. Yet, before long, Einstein was the focus of intense international adulation by millions of people. Since only a minute fraction of those fans could understand the theory, there had to be another reason for the adulation. It was not the workings or the plausibility of the theory that impressed people so much that they created from it an enduring dogma. It was a psychosocial imperative that characterized all widely defended dogma, including Big Bang Theory, of course, which is the offspring of GTR. Once the new dogma has become entrenched within the educational system, it is done and dusted. Universities (mostly inadvertently) become in effect propaganda machines and produce scientists who quite frankly cannot practice or teach physics any other way." http://philsci-archive.pitt.edu/archive/00000313/ Jos Uffink: "Snow stands up for the view that exact science is, in its own right, an essential part of civilisation, and should not merely be valued for its technological applications. Anyone who does not know the Second Law of Thermodynamics, and is proud of it too, exposes oneself as a Philistine. Snow's plea will strike a chord with every physicist who has ever attended a birthday party. But his call for cultural recognition creates obligations too. Before one can claim that acquaintance with the Second Law is as indispensable to a cultural education as Macbeth or Hamlet, it should obviously be clear what this law states. This question is surprisingly difficult. The Second Law made its appearance in physics around 1850, but a half century later it was already surrounded by so much confusion that the British Association for the Advancement of Science decided to appoint a special committee with the task of providing clarity about the meaning of this law. However, its final report (Bryan 1891) did not settle the issue. Half a century later, the physicist/philosopher Bridgman still complained that there are almost as many formulations of the second law as there have been discussions of it (Bridgman 1941, p. 116). And even today, the Second Law remains so obscure that it continues to attract new efforts at clarification. A recent example is the work of Lieb and Yngvason (1999)......The historian of science and mathematician Truesdell made a detailed study of the historical development of thermodynamics in the period 1822-1854. He characterises the theory, even in its present state, as 'a dismal swamp of obscurity' (1980, p. 6) and 'a prime example to show that physicists are not exempt from the madness of crowds' (ibid. p. 8).......Clausius' verbal statement of the second law makes no sense.... All that remains is a Mosaic prohibition ; a century of philosophers and journalists have acclaimed this commandment ; a century of mathematicians have shuddered and averted their eyes from the unclean.....Seven times in the past thirty years have I tried to follow the argument Clausius offers....and seven times has it blanked and gravelled me.... I cannot explain what I cannot understand.....This summary leads to the question whether it is fruitful to see irreversibility or time-asymmetry as the essence of the second law. Is it not more straightforward, in view of the unargued statements of Kelvin, the bold claims of Clausius and the strained attempts of Planck, to give up this idea? I believe that Ehrenfest-Afanassjewa was right in her verdict that the discussion about the arrow of time as expressed in the second law of the thermodynamics is actually a RED HERRING." http://www.informaworld.com/smpp/con...ent=a909857880 Peter Hayes "The Ideology of Relativity: The Case of the Clock Paradox" : Social Epistemology, Volume 23, Issue 1 January 2009, pages 57-78 Peter Hayes: "In the interwar period there was a significant school of thought that repudiated Einstein's theory of relativity on the grounds that it contained elementary inconsistencies. Some of these critics held extreme right-wing and anti-Semitic views, and this has tended to discredit their technical objections to relativity as being scientifically shallow. This paper investigates an alternative possibility: that the critics were right and that the success of Einstein's theory in overcoming them was due to its strengths as an ideology rather than as a science. The clock paradox illustrates how relativity theory does indeed contain inconsistencies that make it scientifically problematic. These same inconsistencies, however, make the theory ideologically powerful. The implications of this argument are examined with respect to Thomas Kuhn and Karl Popper's accounts of the philosophy of science. (...) The prediction that clocks will move at different rates is particularly well known, and the problem of explaining how this can be so without violating the principle of relativity is particularly obvious. The clock paradox, however, is only one of a number of simple objections that have been raised to different aspects of Einstein's theory of relativity. (Much of this criticism is quite apart from and often predates the apparent contradiction between relativity theory and quantum mechanics.) It is rare to find any attempt at a detailed rebuttal of these criticisms by professional physicists. However, physicists do sometimes give a general response to criticisms that relativity theory is syncretic by asserting that Einstein is logically consistent, but that to explain why is so difficult that critics lack the capacity to understand the argument. In this way, the handy claim that there are unspecified, highly complex resolutions of simple apparent inconsistencies in the theory can be linked to the charge that antirelativists have only a shallow understanding of the matter, probably gleaned from misleading popular accounts of the theory. (...) The argument for complexity reverses the scientific preference for simplicity. Faced with obvious inconsistencies, the simple response is to conclude that Einstein's claims for the explanatory scope of the special and general theory are overstated. To conclude instead that that relativity theory is right for reasons that are highly complex is to replace Occam's razor with a potato masher. (...) The defence of complexity implies that the novice wishing to enter the profession of theoretical physics must accept relativity on faith. It implicitly concedes that, without an understanding of relativity theory's higher complexities, it appears illogical, which means that popular "explanations" of relativity are necessarily misleading. But given Einstein's fame, physicists do not approach the theory for the first time once they have developed their expertise. Rather, they are exposed to and probably examined on popular explanations of relativity in their early training. How are youngsters new to the discipline meant to respond to these accounts? Are they misled by false explanations and only later inculcated with true ones? What happens to those who are not misled? Are they supposed to accept relativity merely on the grounds of authority? The argument of complexity suggests that to pass the first steps necessary to join the physics profession, students must either be willing to suspend disbelief and go along with a theory that appears illogical; or fail to notice the apparent inconsistencies in the theory; or notice the inconsistencies and maintain a guilty silence in the belief that this merely shows that they are unable to understand the theory. The gatekeepers of professional physics in the universities and research institutes are disinclined to support or employ anyone who raises problems over the elementary inconsistencies of relativity. A winnowing out process has made it very difficult for critics of Einstein to achieve or maintain professional status. Relativists are then able to use the argument of authority to discredit these critics. Were relativists to admit that Einstein may have made a series of elementary logical errors, they would be faced with the embarrassing question of why this had not been noticed earlier. Under these circumstances the marginalisation of antirelativists, unjustified on scientific grounds, is eminently justifiable on grounds of realpolitik. Supporters of relativity theory have protected both the theory and their own reputations by shutting their opponents out of professional discourse. (...) The argument that Einstein fomented an ideological rather than a scientific revolution helps to explain of one of the features of this revolution that puzzled Kuhn: despite the apparent scope of the general theory, very little has come out of it. Viewing relativity theory as an ideology also helps to account for Poppers doubts over whether special theory can be retained, given experimental results in quantum mechanics and Einsteins questionable approach to defining simultaneity. Both Kuhn and Popper have looked to the other branch of the theory - Popper to the general and Kuhn to the special - to try and retain their view of Einstein as a revolutionary scientist. According to the view proposed here, this only indicates how special and general theories function together as an ideology, as when one side of the theory is called into question, the other can be called upon to rescue it. The triumph of relativity theory represents the triumph of ideology not only in the profession of physics bur also in the philosophy of science. These conclusions are of considerable interest to both theoretical physics and to social epistemology. It would, however, be naïve to think that theoretical physicists will take the slightest notice of them." http://www.ekkehard-friebe.de/wallace.htm Bryan Wallace: "There is a popular argument that the world's oldest rofession is sexual prostitution. I think that it is far more likely that the oldest profession is scientific prostitution, and that it is still alive and well, and thriving in the 20th century. (...) The people who tend to believe more in theories than in the scientific method of testing theories, and who ignore the evidence against the theories they believe in, should be considered pseudoscientists and not true scientists. To the extent that the professed beliefs are based on the desire for status, wealth, or political reasons, these people are scientific prostitutes. (...) 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. (...) I expect that the scientists of the future will consider the dominant abstract physics theories of our time in much the same light as we now consider the Medieval theories of how many angels can dance on the head of a pin or that the Earth stands still and the Universe moves around it."

Imagine a conscientious scientist considering the following text:
http://philsci-archive.pitt.edu/archive/00000313/ p.39: "A more important objection, it seems to me, is that Clausius bases his conclusion that the entropy increases in a nicht umkehrbar [irreversible] process on the assumption that such a process can be closed by an umkehrbar [reversible] process to become a cycle. This is essential for the definition of the entropy difference between the initial and final states. But the assumption is far from obvious for a system more complex than an ideal gas, or for states far from equilibrium, or for processes other than the simple exchange of heat and work. Thus, the generalisation to all transformations occurring in Nature is somewhat rash." The conscientious scientist quickly finds out that "far from obvious" is a euphemism for "dead wrong": spontaneous transfer of heat from a hot to a cold body CANNOT "be closed by an umkehrbar [reversible] process to become a cycle". In a moment of aberration the scientist sees a paper of his, entitled: "Clausius' Deduction of the Law of Entropy Increase Is Based on a False Axiom" published in Nature or Science. Then the conscientious scientist desperately realizes that he is swimming in the Great Postscientific Ocean where the Ever Increasing Entropy has hundreds of definitions, hundreds of deductions, hundreds of interpretations, hundreds of anything. The power of the concept comes from its multifariousness; any single definition or deduction or interpretation is insignificant. The paper submitted to Nature or Science would not even reach reviewers. Pentcho Valev |

http://www.voxy.co.nz/national/leadi...nstein/5/68244 "Leading Astronomer To Explore Dark Energy And Einstein (...) The universe is expanding faster and faster but it is because of a mysterious force called dark energy or a break down in Einstein's theory of relativity?" http://www.scientificamerican.com/bl...nts-2010-06-18 NEW SCIENTIST: "Claiming that something can move faster than light is a good conversation-stopper in physics. People edge away from you in cocktail parties; friends never return phone calls. You just don't mess with Albert Einstein. (...) Singleton says the basic principle of FTL currents goes back to work by English physicist Oliver Heaviside and German physicist Arnold Sommerfeldt in the 1890s, but was forgotten because Einstein's theories dissuaded physicists from thinking about FTL phenomena, even those that evaded the theories' strictures. I've only just touched on this engrossing physics and I recommend you read the team's papers, beginning with this one. "People just don't think about things moving faster than the speed of light," Singleton says. "This is a completely wide open and unexplored field." http://io9.com/5607692/are-physicist...up-dark-energy Dave Goldberg, Associate Professor of Physics at Drexel University: "The idea of dark energy is so ridiculous that almost every question is based on trying to make it go away. And believe me, I share your concerns. I don't want to believe in dark energy, but I have no choice. (...) Basically, if you want to get rid of dark energy, you have to get rid of relativity." http://www.nytimes.com/2010/01/26/science/26essay.html "The worrying continued. Lawrence Krauss, a cosmologist from Arizona State, said that most theories were wrong. "We get the notions they are right because we keep talking about them," he said. Not only are most theories wrong, he said, but most data are also wrong..." http://www.smithsonianmag.com/scienc.../87150187.html "Dark Energy: The Biggest Mystery in the Universe (...) "We have a complete inventory of the universe," Sean Carroll, a California Institute of Technology cosmologist, has said, "and it makes no sense." http://io9.com/5528758/ask-a-physici...in-dark-matter Dave Goldberg, Associate Professor of Physics at Drexel University: "And don't even get me started about Dark Energy. It's the stuff that accelerates the universe, and if you think you've got a problem with Dark Matter, wait'll you see Dark Energy. It's no so much that we don't understand where Dark Energy could come from; it's just that the "natural" value (the one that comes out of reasonable assumptions based on vacuum energy) is about 10^100 times the density that we actually observe. For my money, this is the absolute biggest problem in physics." http://plus.maths.org/issue37/featur...ein/index.html John Barrow: "Einstein restored faith in the unintelligibility of science. Everyone knew that Einstein had done something important in 1905 (and again in 1915) but almost nobody could tell you exactly what it was. When Einstein was interviewed for a Dutch newspaper in 1921, he attributed his mass appeal to the mystery of his work for the ordinary person: Does it make a silly impression on me, here and yonder, about my theories of which they cannot understand a word? I think it is funny and also interesting to observe. I am sure that it is the mystery of non-understanding that appeals to them...it impresses them, it has the colour and the appeal of the mysterious." http://www.washingtontimes.com/news/...nd-relativism/ Washington Times: "A frequently heard statement of cultural relativism goes like this: "If it feels right for you, it's OK. Who is to say you're wrong?" One individual's experience is as "valid" as another's. There is no "preferred" or higher vantage point from which to judge these things. Not just beauty, but right and wrong are in the eye of the beholder. The "I" indeed is the "ultimate measure." The special theory of relativity imposes on the physical world a claim that is very similar to the one made by relativism. (...) So how come the speed of light always stays the same? Einstein argued that when the observer moves relative to an object, distance and time always adjust themselves just enough to preserve light speed as a constant. Speed is distance divided by time. So, Einstein argued, length contracts and time dilates to just the extent needed to keep the speed of light ever the same. Space and time are the alpha and omega of the physical world. They are the stage within which everything happens. But if they must trim and tarry whenever the observer moves, that puts "the observer" in the driver's seat. Reality becomes observer-dependent. Again, then, we find that the "I" is the ultimate measure. Pondering this in Prague in the 1950s, Beckmann could not accept it. The observer's function is to observe, he said, not to affect what's out there. Relativity meant that two and two didn't quite add up any more and elevated science into a priesthood of obscurity. Common sense could no longer be trusted." ftp://ftp.esat.kuleuven.ac.be/pub/SI...orts/06-46.pdf "From the pedagogical point of view, thermodynamics is a disaster. As the authors rightly state in the introduction, many aspects are "riddled with inconsistencies". They quote V.I. Arnold, who concedes that "every mathematician knows it is impossible to understand an elementary course in thermodynamics". Nobody has eulogized this confusion more colorfully than the late Clifford Truesdell. On page 6 of his book "The Tragicomical History of Thermodynamics" 1822-1854 (Springer Verlag, 1980), he calls thermodynamics "a dismal swamp of obscurity". Elsewhere, in despair of trying to make sense of the writings of some local heros as De Groot, Mazur, Casimir, and Prigogine, Truesdell suspects that there is "something rotten in the (thermodynamic) state of the Low Countries" (see page 134 of Rational Thermodynamics, McGraw-Hill, 1969)." http://www.guardian.co.uk/science/20...tion.education Harry Kroto: "The wrecking of British science....The scientific method is based on what I prefer to call the inquiring mindset. It includes all areas of human thoughtful activity that categorically eschew "belief", the enemy of rationality. This mindset is a nebulous mixture of doubt, questioning, observation, experiment and, above all, curiosity, which small children possess in spades. I would argue that it is the most important, intrinsically human quality we possess, and it is responsible for the creation of the modern, enlightened portion of the world that some of us are fortunate to inhabit. Curiously, for the majority of our youth, the educational system magically causes this capacity to disappear by adolescence.....Do I think there is any hope for UK? I am really not sure." http://www.renewamerica.us/columns/hutchison/080616 "Like bronze idols that are hollow inside, Einstein built a cluster of "Potemkin villages," which are false fronts with nothing behind them. Grigori Potemkin (17391791) was a general-field marshal, Russian statesman, and favorite of Empress Catherine the Great. He is alleged to have built facades of non-existent villages along desolate stretches of the Dnieper River to impress Catherine as she sailed to the Crimea in 1787. Actors posing as happy peasants stood in front of these pretty stage sets and waved to the pleased Empress." 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.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.scientificamerican.com/ar...me-an-illusion Craig Callender: "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." Pentcho Valev |

More remnants of conscience in the era of Postscientism:
http://school.maths.uwa.edu.au/~mike/Trouble.doc Mike Alder: "It is easy to see the consequences of the takeover by the bureaucrats. Bureaucrats favour uniformity, it simplifies their lives. They want rules to follow. They prefer the dead to the living. They have taken over religions, the universities and now they are taking over Science. And they are killing it in the process. The forms and rituals remain, but the spirit is dead. The cold frozen corpse is so much more appealing to the bureaucratic mind-set than the living spirit of the quest for insight. Bureaucracies put a premium on the old being in charge, which puts a stop to innovation. Something perhaps will remain, but it will no longer attract the best minds. This, essentially, is the Smolin position. He gives details and examples of the death of Physics, although he, being American, is optimistic that it can be reversed. I am not. (...) Developing ideas and applying them is done by a certain kind of temperament in a certain kind of setting, one where there is a good deal of personal freedom and a willingness to take risks. No doubt we still have the people. But the setting is gone and will not come back. Science is a product of the renaissance and an entrepreneurial spirit. It will not survive the triumph of bureacracy. Despite having the infrastructure, China never developed Science. And soon the West won't have it either." http://www.aynrand.org/site/PageServ...reg_ls_physics "For two centuries after Isaac Newton, the science of physics served as the leading example of the power of the human mind. Its basic content and method, and the life-saving technology that emerged from it, sent a message that resounded throughout the western world: man can live and prosper by the guidance of reason. However, for the past century, theoretical physicists have been sending a different message. They have rejected causality in favor of chance, logic in favor of contradictions, and reality in favor of fantasy." http://www.guardian.co.uk/science/20.../22/schools.g2 "But instead of celebrating, physicists are in mourning after a report showed a dramatic decline in the number of pupils studying physics at school. The number taking A-level physics has dropped by 38% over the past 15 years, a catastrophic meltdown that is set to continue over the next few years. The report warns that a shortage of physics teachers and a lack of interest from pupils could mean the end of physics in state schools. Thereafter, physics would be restricted to only those students who could afford to go to posh schools. Britain was the home of Isaac Newton, Michael Faraday and Paul Dirac, and Brits made world-class contributions to understanding gravity, quantum physics and electromagnetism - and yet the British physicist is now facing extinction. But so what? Physicists are not as cuddly as pandas, so who cares if we disappear?" http://www.lewrockwell.com/orig6/ingdahl2.html "But there has been a marked global decrease of students willing to study physics, and funding has decreased accordingly. Not only that, the best students are not heading for studies in physics, finding other fields more appealing, and science teachers to schools are getting scarcer in supply. In fact, warning voices are being heard about the spread of a "scientific illiteracy" where many living in technologically advanced societies lack the knowledge and the ability for critical thinking in order to function in their daily environment." http://www.worldscibooks.com/chemist...69_preface.pdf "I believe that the time is ripe to acknowledge that the term entropy, as originally coined by Clausius, is an unfortunate choice. Moreover, it is also a misleading term both in its meaning in ancient and in contemporary Greek. On this matter, I cannot do any better than Leon Cooper (1968). Cooper cites the original passage from Clausius: in choosing the word "Entropy," Clausius wrote: "I prefer going to the ancient languages for the names of important scientific quantities, so that they mean the same thing in all living tongues. I propose, accordingly, to call S the entropy of a body, after the Greek word "transformation." I have designedly coined the word entropy to be similar to energy, for these two quantities are so analogous in their physical significance, that an analogy of denominations seems to be helpful." Right after quoting Clausius' explanation on his reasons for the choice of the word "Entropy," Cooper commented: "By doing this, rather than extracting a name from the body of the current language (say: lost heat), he succeeded in coining a word that meant the same thing to everybody: nothing." I fully agree with Cooper's comment; however, I have two additional comments, and contrary to Cooper, I venture into taking the inevitable conclusion: First, I agree that "entropy means the same thing to everybody: nothing." But more than that, entropy is also a misleading term...."

In 1907 Einstein realized that the speed of photons varies with the
gravitational potential in accordance with Newton's emission theory of light. That is, in a gravitational field, both photons and cannonballs undergo the same acceleration. At that time it was almost obvious that, if the speed of light varies with the gravitational potential, it varies with the speed of the light source as well. That is, at least as early as in 1907, Einstein was sure that his 1905 constant- speed-of-light postulate was false. In the era of Postscientism the whole story is buried under multiple layers of camouflage but still remnants of conscience make Einsteinians hint at it from time to time: http://www.pitt.edu/~jdnorton/papers...UP_TimesNR.pdf John Norton: "Already in 1907, a mere two years after the completion of the special theory, he [Einstein] had concluded that the speed of light is variable in the presence of a gravitational field." http://www.logosjournal.com/issue_4.3/smolin.htm 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." 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.blazelabs.com/f-g-gcont.asp "So, faced with this evidence most readers must be wondering why we learn about the importance of the constancy of speed of light. Did Einstein miss this? Sometimes I find out that what's written in our textbooks is just a biased version taken from the original work, so after searching within the original text of the theory of GR by Einstein, I found this quote: "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. Now we might think that as a consequence of this, the special theory of relativity and with it the whole theory of relativity would be laid in the dust. But in reality this is not the case. We can only conclude that the special theory of relativity cannot claim an unlimited domain of validity ; its results hold only so long as we are able to disregard the influences of gravitational fields on the phenomena (e.g. of light)." - Albert Einstein (1879-1955) - The General Theory of Relativity: Chapter 22 - A Few Inferences from the General Principle of Relativity-. 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." Joao Magueijo, PLUS VITE QUE LA LUMIERE, Dunod, 2003, pp. 50-51: "En cours de route, en 1911, Einstein proposa même une théorie où la vitesse de la lumière variait! Aujourd'hui, les scientifiques sont soit horrifiés par cette article écrit par le grand Albert Einstein, alors professeur à Prague, soit tout simplement ignorants de son existence. Banesh Hoffmann, collègue et biographe d'Einstein, décrit ce texte de la manière suivante: "Et cela signifie... Quoi! Que la vitesse de la lumière n'est pas constante, que la gravitation la ralentit. Hérésie! Et de la part d'Einstein lui-même." http://ustl1.univ-lille1.fr/culture/...40/pgs/4_5.pdf Jean Eisenstaedt: "Il n'y a alors aucune raison théorique à ce que la vitesse de la lumière ne dépende 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 lumière se comporte autrement - quant à sa trajectoire - qu'une particule matérielle. Il n'y a pas non plus de raison pour que la lumière ne soit pas sensible à la gravitation. Bref, pourquoi ne pas appliquer à la lumière toute la théorie newtonienne ? C'est en fait ce que font plusieurs astronomes, opticiens, philosophes de la nature à la fin du XVIIIème siècle. Les résultats sont étonnants... et aujourd'hui nouveaux. (...) Même s'il était conscient de l'intérêt de la théorie de l'émission, Einstein n'a pas pris le chemin, totalement oublié, de Michell, de Blair, des Principia en somme. Le contexte de découverte de la relativité ignorera le XVIIIème siècle et ses racines historiques plongent au coeur du XIXème siècle. Arago, Fresnel, Fizeau, Maxwell, Mascart, Michelson, Poincaré, Lorentz en furent les principaux acteurs et l'optique ondulatoire le cadre dans lequel ces questions sont posées. Pourtant, au plan des structures physiques, l'optique relativiste des corps en mouvement de cette fin du XVIIIème est infiniment plus intéressante - et plus utile pédagogiquement - que le long cheminement qu'a imposé l'éther." http://www.passiondulivre.com/livre-...ravitation.htm "Étrangement, personne n'est jamais vraiment allé voir ce que l'on en pensait «avant», avant Einstein, avant Poincaré, avant Maxwell. Pourtant, quelques savants austères et ignorés, John Michell, Robert Blair et d'autres encore, s'y sont intéressés, de très près. Newtoniens impénitents, ces «philosophes de la nature» ont tout simplement traité la lumière comme faite de vulgaires particules matérielles : des «corpuscules lumineux». Mais ce sont gens sérieux et ils se sont basés sur leurs Classiques, Galilée, Newton et ses Principia où déjà l'on trouve des idées intéressantes. À la fin du XVIIIe siècle, au siècle des Lumières (si bien nommé en l'occurrence !), en Angleterre, en Écosse, en Prusse et même à Paris, une véritable balistique de la lumière sous-tend silencieusement la théorie de l'émission, avatar de la théorie corpusculaire de la lumière de Newton. Lus à la lumière (!) des théories aujourd'hui acceptées, les résultats ne sont pas minces. (...) Les «relativités» d'Einstein, cinématique einsteinienne et théorie de la gravitation, ont la triste réputation d'être difficiles... Ne remettent-elles pas en cause des notions familières ? Leur «refonte» est d'autant plus nécessaire. Cette préhistoire en est un nouvel acte qui offre un autre chemin vers ces théories délicates. Mais ce chemin, aussi long soit- il, est un raccourci, qu'il est temps, cent ans après «la» relativité d'Einstein, de découvrir et d'explorer." http://www.arte.tv/fr/La-relativite-...ve/856858.html Jean Eisenstaedt: "Michell est persuadé de l'universalité de la gravitation et que la lumière doit, comme tout autre corpuscule, y être soumise. Il en déduit, en cette fin du xviiie siècle, qu'un corpuscule lumineux, émis par une étoile animée d'une vitesse constante, va être petit à petit freiné et sa vitesse diminuée. À tel point que, si l'étoile est très massive, le corpuscule, telle une pierre jetée en l'air, peut s'arrêter dans sa course et retomber sur l'étoile. Aussi invente-t-il ces objets étranges que Pierre-Simon Laplace nommera «corps obscurs» (car leur lumière ne peut nous en parvenir) et qui s'apparentent aux trous noirs. En 1801, s'appuyant sur ces résultats vulgarisés par Laplace, l'astronome allemand Georg von Soldner en déduira qu'un rayon lumineux peut être dévié de sa course s'il passe près d'un corps pesant. Ses résultats ne sont aucunement différents de ceux d'Einstein, qui calculera le même effet en 1911." http://www.mathpages.com/rr/s6-01/6-01.htm "In geometrical units we define c_0 = 1, so Einstein's 1911 formula can be written simply as c=1+phi. However, this formula for the speed of light (not to mention this whole approach to gravity) turned out to be incorrect, as Einstein realized during the years leading up to 1915 and the completion of the general theory. In fact, the general theory of relativity doesn't give any equation for the speed of light at a particular location, because the effect of gravity cannot be represented by a simple scalar field of c values. Instead, the "speed of light" at a each point depends on the direction of the light ray through that point, as well as on the choice of coordinate systems, so we can't generally talk about the value of c at a given point in a non- vanishing gravitational field. However, if we consider just radial light rays near a spherically symmetrical (and non- rotating) mass, and if we agree to use a specific set of coordinates, namely those in which the metric coefficients are independent of t, then we can read a formula analogous to Einstein's 1911 formula directly from the Schwarzschild metric. (...) In the Newtonian limit the classical gravitational potential at a distance r from mass m is phi=-m/r, so if we let c_r = dr/dt denote the radial speed of light in Schwarzschild coordinates, we have c_r =1+2phi, which corresponds to Einstein's 1911 equation, except that we have a factor of 2 instead of 1 on the potential term." http://www.speed-light.info/speed_of_light_variable.htm "Einstein wrote this paper in 1911 in German (download from: http://www.physik.uni-augsburg.de/an...35_898-908.pdf ). It predated the full formal development of general relativity by about four years. You can find an English translation of this paper in the Dover book 'The Principle of Relativity' beginning on page 99; 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+phi/c^2) where phi is the gravitational potential relative to the point where the speed of light co is measured......You can find a more sophisticated derivation later by Einstein (1955) from the full theory of general relativity in the weak field approximation....For the 1955 results but not in coordinates see page 93, eqn (6.28): c(r)=[1+2phi(r)/c^2]c. Namely the 1955 approximation shows a variation in km/sec twice as much as first predicted in 1911." Pentcho Valev |

Russell Stannard: "I think science will go out with a whimper rather than a bang. You'll get into a situation where for a very, very, very long time nothing interesting happens and people start to think, well, becoming a research scientist is probably not a good career move." http://archives.lesechos.fr/archives...077-80-ECH.htm "Physicien au CEA, professeur et auteur, Etienne Klein s'inquiète des relations de plus en plus conflictuelles entre la science et la société. (...) "Je me demande si nous aurons encore des physiciens dans trente ou quarante ans", remarque ce touche-à-tout aux multiples centres d'intérêt : la constitution de la matière, le temps, les relations entre science et philosophie. (...) Etienne Klein n'est pas optimiste. Selon lui, il se pourrait bien que l'idée de progrès soit tout bonnement "en train de mourir sous nos yeux"." http://www.newstatesman.com/books/20...world-true-end "Nonsensical posturing about science has become commonplace. This is caused, I think, by the triumphalist tone of the wave, now abating, of popular science books started by Stephen Hawking's A Brief History of Time. Physicists used to crow they were on the verge of a "Theory of Everything", biologists said they had cracked the code of life and neuroscientists, accompanied by certain philosophers, claimed the mystery of consciousness would soon yield. None of these things was, or is, true. They are not true because all these problems have proved far more complex than anybody expected. But are they also not true for a more profound reason? Are they not true because they are insoluble, because the human mind is incapable of understanding the world fully? The physicist Russell Stannard thinks this may be the case. He believes that science will eventually come to an end, and that we are living in a "transient age of human development" in which scientific discoveries can be made. But science won't end because we know everything; it will end because we know everything we can know." An important correction needs to be made in the above text: "But science won't end because we know everything; it will end because we know everything NONSENSICAL we can know": http://www.wickedlocal.com/pembroke/...lton-Ratcliffe Hilton Ratcliffe: "If, as in the case of GTR and later with Big Bang Theory and Black Hole theory, the protagonists have seductive charisma (which Einstein, Gamow, and Hawking, respectively, had in abundance) then the theory, though not the least bit understood, becomes the darling of the media. GTR and Big Bang Theory are sacrosanct, and it's most certainly not because they make any sense. In fact, they have become the measure by which we sanctify nonsense. http://plus.maths.org/issue37/featur...ein/index.html John Barrow: "Einstein restored faith in the unintelligibility of science." http://philsci-archive.pitt.edu/archive/00000313/ Jos Uffink: "The historian of science and mathematician Truesdell made a detailed study of the historical development of thermodynamics in the period 1822-1854. He characterises the theory, even in its present state, as 'a dismal swamp of obscurity' and 'a prime example to show that physicists are not exempt from the madness of crowds'." http://www.smithsonianmag.com/scienc.../87150187.html "Dark Energy: The Biggest Mystery in the Universe (...) "We have a complete inventory of the universe," Sean Carroll, a California Institute of Technology cosmologist, has said, "and it makes no sense." http://www.ekkehard-friebe.de/wallace.htm Bryan Wallace: "I expect that the scientists of the future will consider the dominant abstract physics theories of our time in much the same light as we now consider the Medieval theories of how many angels can dance on the head of a pin or that the Earth stands still and the Universe moves around it." Pentcho Valev wrote: Imagine a conscientious scientist considering the following text: http://philsci-archive.pitt.edu/archive/00000313/ p.39: "A more important objection, it seems to me, is that Clausius bases his conclusion that the entropy increases in a nicht umkehrbar [irreversible] process on the assumption that such a process can be closed by an umkehrbar [reversible] process to become a cycle. This is essential for the definition of the entropy difference between the initial and final states. But the assumption is far from obvious for a system more complex than an ideal gas, or for states far from equilibrium, or for processes other than the simple exchange of heat and work. Thus, the generalisation to all transformations occurring in Nature is somewhat rash." The conscientious scientist quickly finds out that "far from obvious" is a euphemism for "dead wrong": spontaneous transfer of heat from a hot to a cold body CANNOT "be closed by an umkehrbar [reversible] process to become a cycle". In a moment of aberration the scientist sees a paper of his, entitled: "Clausius' Deduction of the Law of Entropy Increase Is Based on a False Axiom" published in Nature or Science. Then the conscientious scientist desperately realizes that he is swimming in the Great Postscientific Ocean where the Ever Increasing Entropy has hundreds of definitions, hundreds of deductions, hundreds of interpretations, hundreds of anything. The power of the concept comes from its multifariousness; any single definition or deduction or interpretation is insignificant. The paper submitted to Nature or Science would not even reach reviewers. Pentcho Valev |

Jean-Marc Lévy-Leblond: remnants of conscience:
http://www.archipope.net/article-12278372-6.html "Nous nous trouvons dans une période de mutation extrêmement profonde. Nous sommes en effet à la fin de la science telle que l'Occident l'a connue », tel est constat actuel que dresse Jean-Marc Lévy-Leblond, physicien théoricien, épistémologue et directeur des collections scientifiques des Editions du Seuil. Devant cette crise « technoscientifique » que connaissent les sciences dures, il défend la nécessité d'opérer en leur sein une nouvelle forme de critique de « science » ou, pour reprendre le terme de Bachelard, de « refonte » de tout un système de pensée. Ce n'est selon lui qu'au prix d'une « mise à l'épreuve » de la science par l'analyse des processus intellectuels, matériels, voire politiques ou idéologiques qui ont présidés à la constitution d'un savoir qu'elle sera à même de renouer avec la société dans son ensemble. L'idée d'une mise en partage critique des sciences est ainsi conçue comme une garantie démocratique." Bravo, Monsieur Jean-Marc Lévy-Leblond! Evidemment vous n'êtes plus le Tomás de Torquemada de la science théorique en France! Maintenant l'analyse des processus intellectuels, matériels, voire politiques ou idéologiques qui ont présidé à la constitution du "savoir" suivant pourrait commencer: 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://www.quebecscience.qc.ca/Revolutions "Cependant, si une fusée de 100 m passait devant nous à une vitesse proche de celle de la lumière, elle pourrait sembler ne mesurer que 50 m, ou même moins. Bien sûr, la question qui vient tout de suite à l'esprit est: «Cette contraction n'est-elle qu'une illusion?» Il semble tout à fait incroyable que le simple mouvement puisse comprimer un objet aussi rigide qu'une fusée. Et pourtant, la contraction est réelle... mais SANS COMPRESSION physique de l'objet! Ainsi, une fusée de 100 m passant à toute vitesse dans un tunnel de 60 m pourrait être entièrement contenue dans ce tunnel pendant une fraction de seconde, durant laquelle il serait possible de fermer des portes aux deux bouts! La fusée est donc réellement plus courte. Pourtant, il n'y a PAS DE COMPRESSION matérielle ou physique de l'engin. Comment est-ce possible?" http://math.ucr.edu/home/baez/physic...barn_pole.html "These are the props. You own a barn, 40m long, with automatic doors at either end, that can be opened and closed simultaneously by a switch. You also have a pole, 80m long, which of course won't fit in the barn. Now someone takes the pole and tries to run (at nearly the speed of light) through the barn with the pole horizontal. Special Relativity (SR) says that a moving object is contracted in the direction of motion: this is called the Lorentz Contraction. So, if the pole is set in motion lengthwise, then it will contract in the reference frame of a stationary observer.....So, as the pole passes through the barn, there is an instant when it is completely within the barn. At that instant, you close both doors simultaneously, with your switch. Of course, you open them again pretty quickly, but at least momentarily you had the contracted pole shut up in your barn. The runner emerges from the far door unscathed.....If the doors are kept shut the rod will obviously smash into the barn door at one end. If the door withstands this the leading end of the rod will come to rest in the frame of reference of the stationary observer. There can be no such thing as a rigid rod in relativity so the trailing end will not stop immediately and the rod will be compressed beyond the amount it was Lorentz contracted. If it does not explode under the strain and it is sufficiently elastic it will come to rest and start to spring back to its natural shape but since it is too big for the barn the other end is now going to crash into the back door and the rod will be trapped IN A COMPRESSED STATE inside the barn." http://alcor.concordia.ca/~scol/semi...ts/Durand.html "La contraction une longueur est un phénomène à la fois réel mais sans déformation structurelle. C'est un phénomène réel (et non pas une illusion) car, par exemple, une perche dont la longueur au repos est plus grande que la longueur au repos d'une grange peut réellement être contenue dans cette dernière si elle se déplace assez rapidement. Par contre, il ne peut y avoir de contraction structurelle de la perche, i.e de déformation matérielle de l'objet, car la contraction de sa longueur aurait aussi lieu si c'était plutôt l'observateur qui se mettait en mouvement sans changer l'état de mouvement de la perche. Autrement dit, sans changer l'état de la perche, en se mettant soi- même en mouvement, on change sa longueur: ce n'est donc clairement pas une contraction matérielle (l'état de la perche est le même dans les deux cas)." http://inac.cea.fr/Phocea/file.php?c...43/t343_1..pdf Gilles Cohen-Tannoudji: "Chez Poincaré, la contraction des longueurs et la dilatation des durées sont réelles.....Chez Einstein, la contraction des longueurs et la dilatation des durées ne sont pas réelles: elles sont le résultat d'un effet de perspective." http://www.academie-sciences.fr/memb...ein_Damour.pdf Thibault Damour: "La "contraction des longueurs" avait, avant Einstein, été considérée par George Fitzgerald et Hendrik Lorentz. Cependant, ils la considéraient comme un effet "réel" de contraction dans l' "espace absolu", alors que pour Einstein il s'agit d'un effet de perspective spatio-temporelle." Pentcho Valev |

DISCOVER: "Roger Penrose Says Physics Is Wrong, From String Theory to Quantum Mechanics" If Roger Penrose, one of the high priests of Postscientism, says so the situation is more than desperate. Yet salvation does exist: the scientific community should organize a conference entitled: "Validity or Invalidity of Clausius' 1850 Argument?" where the following text will be put to close scrutiny: http://www.mdpi.org/lin/clausius/clausius.htm "Ueber die bewegende Kraft der Wärme", 1850, Rudolf Clausius: "Carnot assumed, as has already been mentioned, that the equivalent of the work done by heat is found in the mere transfer of heat from a hotter to a colder body, while the quantity of heat remains undiminished. The latter part of this assumption--namely, that the quantity of heat remains undiminished--contradicts our former principle, and must therefore be rejected... (...) It is this maximum of work which must be compared with the heat transferred. When this is done it appears that there is in fact ground for asserting, with Carnot, that it depends only on the quantity of the heat transferred and on the temperatures t and tau of the two bodies A and B, but not on the nature of the substance by means of which the work is done. (...) If we now suppose that there are two substances of which the one can produce more work than the other by the transfer of a given amount of heat, or, what comes to the same thing, needs to transfer less heat from A to B to produce a given quantity of work, we may use these two substances alternately by producing work with one of them in the above process. At the end of the operations both bodies are in their original condition; further, the work produced will have exactly counterbalanced the work done, and therefore, by our former principle, the quantity of heat can have neither increased nor diminished. The only change will occur in the distribution of the heat, since more heat will be transferred from B to A than from A to B, and so on the whole heat will be transferred from B to A. By repeating these two processes alternately it would be possible, without any expenditure of force or any other change, to transfer as much heat as we please from a cold to a hot body, and this is not in accord with the other relations of heat, since it always shows a tendency to equalize temperature differences and therefore to pass from hotter to colder bodies." Since Clausius' 1850 invalid argument marks the beginning of Postscientism, the success of the conference would mean that the right first step towards the resurrection of Science has been made. To use an oversimplification, Postscientism consists in deducing breathtaking absurdities by means of false axioms and invalid arguments. Pentcho Valev |

wrote: What's the former principle? (...) If you want present an argument for debate, Pentcho, present all the information. I can't "put to close scrutiny" something as vague as "former principle". The "former principle" is given earlier in Clausius' text: http://www.mdpi.org/lin/clausius/clausius.htm "To this it must be added that other facts have lately become known which support the view, that heat is not a substance, but consists in a motion of the least parts of bodies. If this view is correct, it is admissible to apply to heat the general mechanical principle that a motion may be transformed into work, and in such a manner that the loss of kinetic energy is proportional to the work accomplished. These facts, with which Carnot also was well acquainted and the importance of which he has expressly recognized, almost compel us to accept the equivalence between heat and work, on the modified hypothesis that the accomplishment of work requires not merely a change in the distribution of heat, but also an actual consumption of heat, and that, conversely, heat can be developed again by the expenditure of work."

Herbert Dingle, SCIENCE AT THE CROSSROADS "According to the special relativity theory, as expounded by Einstein in his original paper, two similar, regularly-running clocks, A and B, in uniform relative motion, must work at different rates.....How is the slower-working clock distinguished? The supposition that the theory merely requires each clock to APPEAR to work more slowly from the point of view of the other is ruled out not only by its many applications and by the fact that the theory would then be useless in practice, but also by Einstein's own examples, of which it is sufficient to cite the one best known and most often claimed to have been indirectly established by experiment, viz. 'Thence' [i.e. from the theory he had just expounded, which takes no account of possible effects of accleration, gravitation, or any difference at all between the clocks except their state of uniform motion] 'we conclude that a balance-clock at the equator must go more slowly, by a very small amount, than a precisely similar clock situated at one of the poles under otherwise identical conditions.' Applied to this example, the question is: what entitled Einstein to conclude FROM HIS THEORY that the equatorial, and not the polar, clock worked more slowly?" http://articles.adsabs.harvard.edu/c...&filetype=.pdf Herbert Dingle: "...the internal consistency of the restricted relativity theory seems questionable if the postulate of the constancy of the velocity of light is given its usual interpretation... (...) These difficulties are removed if the postulate be interpreted MERELY as requiring that the velocity of light relative to its actual material source shall always be c..." http://irfu.cea.fr/Phocea/file.php?f...TE-052-456.pdf Jean-Marc Bonnet-Bidaud Relativité: Les preuves étaient fausses "Le monde entier a cru pendant plus de cinquante ans à une théorie non vérifiée. Car, nous le savons aujourd'hui, les premières preuves, issues notamment d'une célèbre éclipse de 1919, n'en étaient pas. Elles reposaient en partie sur des manipulations peu avouables visant à obtenir un résultat connu à l'avance, et sur des mesures entachées d'incertitudes, quand il ne s'agissait pas de fraudes caractérisées. Il aura fallu attendre les années 1970 pour que de nouvelles méthodes parviennent enfin à fournir des preuves expérimentales solides de la relativité. Cet épisode, encore peu connu, illustre la façon dont les certitudes scientifiques s'établissent parfois sur des bases douteuses. Aujourd'hui encore, des observations bien fragiles comme celles des lointaines supernovae, qui semblent indiquer une accélération de l'expansion de l'Univers et l'existence d'une énergie du vide inconnue, semblent tout aussi aléatoires, alors qu'elles sont souvent considérées comme définitives. Devant la pression du résultat, l'objectivité scientifique se trouve bien souvent négligée." Note that the statement: "Il aura fallu attendre les années 1970 pour que de nouvelles méthodes parviennent enfin à fournir des preuves expérimentales solides de la relativité." sounds idiotic (Einsteinians had been lying for 60 years when in the 1970's they suddenly became honest) but Jean-Marc Bonnet-Bidaud had no choice: without this statement he would have been dismissed and marginalized immediately. Einsteiniana knows no limits. Pentcho Valev |
