A light source on top of a tower of height h emits light with
frequency f, speed c (relative to the source) and wavelength L. A receiver on the ground receives light with frequency f', speed c' (relative to the receiver) and wavelength L'. According to Newton's emission theory of light: f'=f(1+gh/c^2); c'=c(1+gh/c^2); L'=L A rocket of length h accelerates with acceleration g. A light source at the front end emits light with frequency f, speed c (relative to the source) and wavelength L. A receiver at the back end receives light with frequency f', speed c' (relative to the receiver) and wavelength L'. At the moment of reception, the receiver has speed v relative to the light source at the moment of emission. According to Newton's emission theory of light: f'=f(1+v/c); c'=c+v; L'=L Einstein did not offer any reasonable alternative to the variation of the speed of light in a gravitational field predicted by the emission theory. Initially he was just using the emission theory equation c'=c(1+gh/c^2), then quite stupidly (or dishonestly) replaced it with c'=c(1+2gh/c^2). Here "stupidly" and "dishonestly" refer to the fact that c'=c(1+2gh/c^2) is not consistent with the gravitational redshift factor advanced by Einstein himself and experimentally confirmed by Pound and Rebka: 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." 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." Since the variability of the speed of light in a gravitational field is a fundamental tenet of Einstein's general relativity, it would be extremely difficult to camouflage it in a world where scientific rationality still exists. In Einsteiniana's schizophrenic world no camouflage is necessary: Einsteinians simply declare that the speed of light is constant in a gravitational field and that's it (believers sing "Divine Einstein" and "Yes we all believe in relativity, relativity, relativity" all along): http://www.amazon.com/Brief-History-.../dp/0553380168 Stephen Hawking, "A Brief History of Time", Chapter 6: "Under the theory that light is made up of waves, it was not clear how it would respond to gravity. But if light is composed of particles, one might expect them to be affected by gravity in the same way that cannonballs, rockets, and planets are.....In fact, it is not really consistent to treat light like cannonballs in Newtons theory of gravity because the speed of light is fixed. (A cannonball fired upward from the earth will be slowed down by gravity and will eventually stop and fall back; a photon, however, must continue upward at a constant speed...)" http://www.hawking.org.uk/index.php?...64&It emid=66 Stephen Hawking: "Interestingly enough, Laplace himself wrote a paper in 1799 on how some stars could have a gravitational field so strong that light could not escape, but would be dragged back onto the star. He even calculated that a star of the same density as the Sun, but two hundred and fifty times the size, would have this property. But although Laplace may not have realised it, the same idea had been put forward 16 years earlier by a Cambridge man, John Mitchell, in a paper in the Philosophical Transactions of the Royal Society. Both Mitchell and Laplace thought of light as consisting of particles, rather like cannon balls, that could be slowed down by gravity, and made to fall back on the star. But a famous experiment, carried out by two Americans, Michelson and Morley in 1887, showed that light always travelled at a speed of one hundred and eighty six thousand miles a second, no matter where it came from. How then could gravity slow down light, and make it fall back." http://math.ucr.edu/home/baez/physic..._of_light.html Steve Carlip: "Einstein went on to discover a more general theory of relativity which explained gravity in terms of curved spacetime, and he talked about the speed of light changing in this new theory. In the 1920 book "Relativity: the special and general theory" he wrote: ". . . 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 [. . .] 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." Since Einstein talks of velocity (a vector quantity: speed with direction) rather than speed alone, it is not clear that he meant the speed will change, but the reference to special relativity suggests that he did mean so. THIS INTERPRETATION IS PERFECTLY VALID AND MAKES GOOD PHYSICAL SENSE, BUT A MORE MODERN INTERPRETATION IS THAT THE SPEED OF LIGHT IS CONSTANT in general relativity." http://www.haverford.edu/physics/songs/divine.htm No-one's as dee-vine as Albert Einstein Not Maxwell, Curie, or Bohr! He explained the photo-electric effect, And launched quantum physics with his intellect! His fame went glo-bell, he won the Nobel -- He should have been given four! No-one's as dee-vine as Albert Einstein, Professor with brains galore! No-one could outshine Professor Einstein -- Egad, could that guy derive! He gave us special relativity, That's always made him a hero to me! Brownian motion, my true devotion, He mastered back in aught-five! No-one's as dee-vine as Albert Einstein, Professor in overdrive! http://www.youtube.com/watch?v=5PkLLXhONvQ We all believe in relativity, relativity, relativity. Yes we all believe in relativity, 8.033, relativity. Einstein's postulates imply That planes are shorter when they fly. Their clocks are slowed by time dilation And look warped from aberration. We all believe in relativity, relativity, relativity. Yes we all believe in relativity, 8.033, relativity. Pentcho Valev |

Another unambiguous rejection of Einstein's relativity (Einsteinians
do not react, the rest of the world does not care): http://redshift.vif.com/JournalFiles...F/V17N1GIF.pdf Doppler Shift Reveals Light Speed Variation Stephan J. G. Gift Department of Electrical and Computer Engineering The University of the West Indies "Therefore the observed Doppler Shift or frequency change in the light or other electromagnetic radiation resulting from movement of the receiver toward the transmitter indicates a change in light speed relative to the moving receiver. (...) In conclusion, a change in radiation frequency or Doppler Shift occurs when an observer moving at speed v c towards or away from a stationary source intercepts electromagnetic waves from that source. This frequency change arises because the observer intercepts the electromagnetic radiation at a relative speed c ± v that is different from the light speed c. Though special relativity predicts the Doppler Shift, this light speed variation c ± v occurring in this situation directly contradicts the light speed invariance requirement of special relativity." The silence surrounding Einstein's 1905 false light postulate in Einsteiniana's schizophrenic world is equivalent to the silence surrounding the equality 2+2=5 in Big Brother's schizophrenic world: 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?" Pentcho Valev wrote: Einstein's relativity started with the rejection of Newton's thesis that the speed of light varies exactly as the speed of cannonballs does: http://www.amazon.com/Relativity-Its.../dp/0486406768 "Relativity and Its Roots" By Banesh Hoffmann "Moreover, if light consists of particles, as Einstein had suggested in his paper submitted just thirteen weeks before this one, the second principle seems absurd: A stone thrown from a speeding train can do far more damage than one thrown from a train at rest; the speed of the particle is not independent of the motion of the object emitting it. And if we take light to consist of particles and assume that these particles obey Newton's laws, they will conform to Newtonian relativity and thus automatically account for the null result of the Michelson-Morley experiment without recourse to contracting lengths, local time, or Lorentz transformations. Yet, as we have seen, Einstein resisted the temptation to account for the null result in terms of particles of light and simple, familiar Newtonian ideas, and introduced as his second postulate something that was more or less obvious when thought of in terms of waves in an ether."

"The end of Einstein's relativity" does not mean that Einstein's
relativity is no longer a money-spinner: http://www.physorg.com/news198431059.html "The new results show that the growth of cosmic structure is consistent with the predictions of General Relativity, supporting the view that dark energy drives cosmic acceleration." http://www.physorg.com/news179508040.html "More than a dozen ground-based Dark Energy projects are proposed or under way, and at least four space-based missions, each of the order of a billion dollars, are at the design concept stage." "The end of Einstein's relativity" simply means that Einsteiniana's priests will exercise their priesthood somewhere else: http://www.edge.org/q2008/q08_5.html 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. (...) 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."

ELEVENTH INTERNATIONAL SYMPOSIUM Frontiers of Fundamental Physics [FFP11] 6-9 July 2010 | Paris, France Do you see signs, e.g. in the invited speakers' communications, that Einstein's relativity is still alive?

It was called the "emission theory" of light, a phrase I shall use. (...) Giving up the ether concept allowed Einstein to envisage the possibility that a beam of light was "an independent structure," as he put it a few years later, "which is radiated by the light source, just as in Newton's emission theory of light." (...) An emission theory is perfectly compatible with the relativity principle. Thus, the M-M experiment presented no problem; nor is stellar abberration difficult to explain on this basis. (...) 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.

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. (...)

Hey, Valev. Take another look at the article. I wrote them and pointed out the possibility that it might be misunderstood, as you did. Nature thoughtfully swapped "light" and "heavy" to eliminate the possibility of confusion. The sentence now reads: "Gravity is mercilessly impartial — on Earth, it accelerates heavy and light objects alike with a tug of 9.8 metres per second squared." This is the second time I've had to write to a publication to clarify their writing *just* *for* *you*. You're welcome. Mark L. Fergerson |

Einstein's children in France used to denounce Poincaré's principle of
diversity of theoretical representations and fiercely defend Einstein's principle of uniqueness of theoretical representations: http://www.academie-sciences.fr/memb...gol%20_amp.pdf Olivier Darrigol: "Seul Einstein eut l'audace de déclarer que les divers référentiels inertiels étaient entièrement équivalents, que les temps et les espaces mesurés dans chacun d'entre eux étaient tous sur le même pied. Il se persuada d'une exacte validité du principe de relativité vers 1901, avant d'avoir lu Poincaré. Contrairement à ce dernier, il accompagnait cette conviction du rejet du concept d'éther, au nom d'un principe épistémologique d'univocité des représentations théoriques : à un seul et même phénomène devait correspondre une seule représentation théorique." Einstein's relativity has come to an end but Einstein's children have to eat - they are Poincaré's children now and denounce Einstein's principle of uniqueness of theoretical representations and fiercely defend Poincaré's principle of diversity of theoretical representations: http://www.rehseis.cnrs.fr/spip.php?article570 Olivier Darrigol: "L'étonnante diversité des descriptions théoriques utilisées dans la physique d'hier et d'aujourd'hui est souvent perçue comme une faiblesse temporaire qu'il faudra corriger dans un état plus avancé de cette science. A l'opposé de cette attitude, les héritiers de Maxwell, de Boltzmann et de 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. Nous proposons de les suivre en explorant la manière dont les divers modes, niveaux et ordres de description dépendent des cultures scientifiques dans lesquels ils apparaissent et affectent notre capacité à résoudre des problèmes concrets, nous poussent à étudier de nouvelles sortes de phénomènes et suggèrent de nouveaux objets physiques."

The current fashion in Einsteiniana: Hinting at the end of Einstein's
relativity by denouncing the space-time idiocy: http://www.newscientist.com/article/...spacetime.html NEW SCIENTIST: "Rethinking Einstein: The end of space-time. IT WAS a speech that changed the way we think of space and time. The year was 1908, and the German mathematician Hermann Minkowski had been trying to make sense of Albert Einstein's hot new idea - what we now know as special relativity - describing how things shrink as they move faster and time becomes distorted. "Henceforth space by itself and time by itself are doomed to fade into the mere shadows," Minkowski proclaimed, "and only a union of the two will preserve an independent reality." And so space-time - the malleable fabric whose geometry can be changed by the gravity of stars, planets and matter - was born. It is a concept that has served us well, but if physicist Petr Horava is right, it may be no more than a mirage. (...) Something has to give in this tussle between general relativity and quantum mechanics, and the smart money says that it's relativity that will be the loser." http://www.homevalley.co.za/index.ph...s-are-changing "Einstein introduced a new notion of time, more radical than even he at first realized. In fact, the view of time that Einstein adopted was first articulated by his onetime math teacher in a famous lecture delivered one century ago. That lecture, by the German mathematician Hermann Minkowski, established a new arena for the presentation of physics, a new vision of the nature of reality redefining the mathematics of existence. The lecture was titled Space and Time, and it introduced to the world the marriage of the two, now known as spacetime. It was a good marriage, but lately physicists passion for spacetime has begun to diminish. And some are starting to whisper about possible grounds for divorce. (...) Physicists of the 21st century therefore face the task of finding the true reality obscured by the spacetime mirage. (...) What he and other pioneers on the spacetime frontiers have seen coming is an intellectual crisis. The approaches of the past seem insufficiently powerful to meet the challenges remaining from Einstein's century - such as finding a harmonious mathematical marriage for relativity with quantum mechanics the way Minkowski unified space and time. And more recently physicists have been forced to confront the embarrassment of not knowing what makes up the vast bulk of matter and energy in the universe. They remain in the dark about the nature of the dark energy that drives the universe to expand at an accelerating rate. Efforts to explain the dark energy's existence and intensity have been ambitious but fruitless. To Albrecht, the dark energy mystery suggests that it's time for physics to drop old prejudices about how nature's laws ought to be and search instead for how they really are. And that might mean razing Minkowski's arena and rebuilding it from a new design. It seems to me like it's a time in the development of physics, says Albrecht, where it's time to look at how we think about space and time very differently." http://philsci-archive.pitt.edu/archive/00001661/ MINKOWSKI SPACE-TIME: A GLORIOUS NON-ENTITY Harvey R. Brown, Oliver Pooley "It is argued that Minkowski space-time cannot serve as the deep structure within a "constructive" version of the special theory of relativity, contrary to widespread opinion in the philosophical community." 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.newscientist.com/article/...erse-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." http://www.pitt.edu/~jdnorton/Goodie...age/index.html John Norton: "A common belief among philosophers of physics is that the passage of time of ordinary experience is merely an illusion. The idea is seductive since it explains away the awkward fact that our best physical theories of space and time have yet to capture this passage. I urge that we should resist the idea. We know what illusions are like and how to detect them. Passage exhibits no sign of being an illusion....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 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. There are temporal orderings. We can identify earlier and later stages of temporal processes and everything in between. What we cannot find is a passing of those stages that recapitulates the presentation of the successive moments to our consciousness, all centered on the one preferred moment of "now." At first, that seems like an extraordinary lacuna. It is, it would seem, a failure of our best physical theories of time to capture one of time's most important properties. However the longer one works with the physics, the less worrisome it becomes. (...) I was, I confess, a happy and contented believer that passage is an illusion. It did bother me a little that we seemed to have no idea of just how the news of the moments of time gets to be rationed to consciousness in such rigid doses. (...) Now consider the passage of time. Is there a comparable reason in the known physics of space and time to dismiss it as an illusion? I know of none. The only stimulus is a negative one. We don't find passage in our present theories and we would like to preserve the vanity that our physical theories of time have captured all the important facts of time. So we protect our vanity by the stratagem of dismissing passage as an illusion." Pentcho Valev |

The end of Einstein's relativity was officially announced in the
following coded way: 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." Translation: "Brothers Einsteinians, we are on a sinking ship! "The passage of time is an illusion" is a consequence of Einstein's 1905 light postulate, and the falsehood of the consequence implies falsehood of the postulate! You should quit working on Divine Albert's Divine Theory and become experts in climate science for instance." A previous confession by a high priest in Einsteiniana signalling the end of Einstein's relativity was much more camouflaged and very few Einsteinians took notice of it: http://www.edge.org/q2008/q08_5.html 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. (...) 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." Pentcho Valev |
