ONLY ONE EMISSION THEORY OF LIGHT

George Orwell: "Crimestop means the faculty of stopping short, as though by instinct, at the threshold of any dangerous thought. It includes the power of not grasping analogies, of failing to perceive logical errors, of misunderstanding the simplest arguments if they are inimical to Ingsoc, and of being bored or repelled by any train of thought which is capable of leading in a heretical direction. Crimestop, in short, means protective stupidity." It seems the UK is the only place in the world where crimestop is not absolute and the absurd consequences of Einstein's 1905 false constant- speed-of-light postulate are questioned from time to time: http://www.ufodigest.com/article/exp...ory-everything Roland Michel: "Consider the famous "Twin Paradox" thought experiment, where a speeding astronaut returns to Earth to discover he is much younger than his Earthbound twin. A logical flaw in this paradox claim has been reluctantly but increasingly acknowledged over the years, since “everything is relative” in Special Relativity theory, so either twin could be considered speeding or stationary, removing any absolute age difference. But, should this flaw be pointed out, focus is invariably switched away from Special Relativity since only the astronaut underwent actual physical acceleration in his travels, which is instead the realm of General Relativity. This switch is generally presented as a resolution to the issue - but is it? First, this switch to General Relativity invalidates the still often-claimed support for Special Relativity from both this famous thought experiment and from all related physical experiments, such as speeding particles in accelerators, or atomic clocks on circling airplanes or satellites. Yet this fact is typically neither discussed nor even acknowledged, leaving many with the impression that the Twin Paradox and related physical experiments still fully apply to and support Special Relativity theory. (...) So, according to both the "everything is relative" aspect of Special Relativity and the Principle of Equivalence in General Relativity there would appear to be no such phenomenon as "relativistic time dilation", despite widespread citation of iconic theoretical and experimental claims to the contrary." http://homepage.ntlworld.com/academ/...elativity.html What is wrong with relativity? G. BURNISTON BROWN Bulletin of the Institute of Physics and Physical Society, Vol. 18 (March, 1967) pp.7177 "A more intriguing instance of this so-called 'time dilation' is the well-known 'twin paradox', where one of two twins goes for a journey and returns to find himself younger than his brother who remained behind. This case allows more scope for muddled thinking because acceleration can be brought into the discussion. Einstein maintained the greater youthfulness of the travelling twin, and admitted that it contradicts the principle of relativity, saying that acceleration must be the cause (Einstein 1918). In this he has been followed by relativists in a long controversy in many journals, much of which ably sustains the character of earlier speculations which Born describes as "monstrous" (Born 1956). Surely there are three conclusive reasons why acceleration can have nothing to do with the time dilation calculated: (i) By taking a sufficiently long journey the effects of acceleration at the start, turn-round and end could be made negligible compared with the uniform velocity time dilation which is proportional to the duration of the journey. (ii) If there is no uniform time dilation, and the effect, if any, is due to acceleration, then the use of a formula depending only on the steady velocity and its duration cannot be justified. (iii) There is, in principle, no need for acceleration. Twin A can get his velocity V before synchronizing his clock with that of twin B as he passes. He need not turn round: he could be passed by C who has a velocity V in the opposite direction, and who adjusts his clock to that of A as he passes. When C later passes B they can compare clock readings. As far as the theoretical experiment is concerned, C's clock can be considered to be A's clock returning without acceleration since, by hypothesis, all the clocks have the same rate when at rest together and change with motion in the same way independently of direction. [fn. I am indebted to Lord Halsbury for pointing this out to me.] (...) The three examples which have been dealt with above show clearly that the difficulties are not paradoxes) but genuine contradictions which follow inevitably from the principle of relativity and the physical interpretations of the Lorentz transformations. The special theory of relativity is therefore untenable as a physical theory." 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 "This first appearance of what has become known as time dilation in Einstein's work requires careful attention. In particular, anyone who assumes that the special theory deals only with uniform movement in a straight line and is thus a precisely delineated subset of the later general theory, will wish to explore why Einstein extends his conclusions to polygonal and circular movements. It is by no means "at once apparent" that what is true for a straight line is true for a polygon, nor that what has been "proved" for a polygon applies to a circle. The principle of relativity introduced at the outset of the 1905 paper implicitly limited the special theory to reference frames moving at a constant speed in a straight line with respect to one another. In later work, Einstein explicitly stated that the special theory applied only to a reference frame "in a state of uniform rectilinear and non rotary motion" in respect of a second reference frame, in contrast to the general theory that dealt with reference frames regardless of their state of motion (Einstein 1920, 61). Acceleration, therefore, would appear to be the province of the general theory. A polygon, however, would seem to necessarily involve acceleration whenever there is a abrupt alteration in the direction of travel. Even more confusingly, a circular path, far from allowing movement at a "constant velocity", has a velocity that continually changes. Einstein, it is argued, wished to minimise the significance of acceleration - as he did not mention acceleration at all in the passage, he could hardly be said to do otherwise (Essen 1971, 13). With respect to the transition from the straight line to the polygon, this assumption is corroborated by comments Einstein made in 1911 when he said that the larger the polygon the less significant the impact of a sudden change of direction would be. Einstein 1911: "The [travelling] clock runs slower if it is in uniform motion, but if it undergoes a change of direction as a result of a jolt, then the theory of relativity does not tell us what happens. The sudden change of direction might produce a sudden change in the position of the hands of the clock. However, the longer the clock is moving rectilinearly and uniformly with a given speed in a forward motion, i.e., the larger the dimensions of the polygon, the smaller must be the effect of such a hypothetical sudden change." (Einstein et al. 1993, 354) (...) The argument that the prediction of time difference between a moving and a stationary clock violates the principle of relativity is well known. Certainly, it must have become known to Einstein, for in 1918 he created a dialogue in which "Kritikus" voiced exactly this objection (Einstein 1918). In response to this criticism, Einstein underwent a volte-face, reversing his reasoning in 1905 and 1911. The sudden change in direction of the moving clock, far from having unknown effects that needed to be minimised, was now said to provide the entire explanation for the change. Instead of imagining a moving clock travelling in a huge polygon or circle to make sudden changes in direction as insignificant as possible or the journey as smooth as possible, Einstein imagined an out and back journey. He then explained that the slow-down in the moving clock occurred during the sudden jolt when it went into reverse. (...) Given Einsteins argument in 1918, it seems inescapable that his 1905 prediction of time dilation was not, in fact, a "peculiar consequence" of his forgoing account of special relativity (Einstein 1923, 49). When it is also remembered that in 1904 Lorentz deduced the existence of "local time", it is reasonable to conclude that the prediction that the clocks would end up showing different times can be reached without entering into Einstein's reasoning on the special theory at all. The supporters of Einstein, however, generally maintain that one needs to move beyond the special theory to the general theory to understand why the times shown by the clocks would be different. However, as Einstein's prediction preceded the general theory, this argument is problematic (Lovejoy 1931, 159; Essen 1971, 14). It has been seen that: (a) in 1911 Einstein explicitly rules out the ability of the special theory of relativity to say what happened if the moving clock suddenly changed direction, and (b) in 1918 Einstein tacitly admitted that his explanation of the clock paradox in 1905 was incorrect by transforming the polygonal or circular journey of the moving clock into an out and back journey. If the general theory is necessary to explain the clock paradox, then Einstein must have (a) predicted the effects of acceleration in 1905 even though he did not incorporate them into his theory for another decade, and (b) hidden his intuition by describing a journey that discounted their significance. (...) There is, nonetheless, some divergence about how to resolve the clock paradox amongst mainstream scientists and philosophers who address the issue. The majority suggest that (a) the general theory is required to resolve the paradox because like "Kritikus" they have deduced - quite correctly - that it cannot be explained by the special theory. However, a minority believe that (b) the paradox can be explained by the special theory because they have deduced - again quite correctly - that it is incredible to suppose that only the general theory can explain a prediction ostensibly arising from the prior special theory. Each deduction, considered in isolation, is allowable within the mainstream; what is not permitted is to bring the two of them together to conclude that ( c) neither the special nor the general theory explains time dilation. (...) 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 claim that the theory of relativity is logically consistent for reasons that are too complex for non- professionals to grasp is not only convenient, but is rhetorically unassailable - as whenever a critic disproves one argument, the professional physicist can allude to another more abstruse one. Einstein's transformation of the clock paradox from a purported expression of the special theory to a purported expression of the much more complicated general theory is one example of such a defence. A more recent example is found in Alan Sokal and Jean Bricmont's scornful account of Henri Bergson's attempt to investigate the clock/ twin paradox. Like "Kritikus", Bergson argued that the asymmetric outcome of the paradox was incompatible with the principle of relativity. Like Einstein, Sokal and Bricmont explain that Bergson has failed to recognise the asymmetric forces of acceleration at work. They go on to claim that the special theory tells us what happens under these circumstances and that the general theory only laboriously leads to the same conclusion. The suggestion that to vindicate this claim would be laborious functions in the same way as Einstein's elusive "calculations"; that is, it is not an explanation but an explanation-stopper. Sokal and Bricmont do not demonstrate how either the special theory or the general theory explain time dilation. Nor do they explain how their claim can be reconciled with Einstein explicitly limiting the special theory to objects travelling at a uniform velocity, nor account for why the circular journey of 1905 became the out and back journey of 1918. (...) Einstein's theory of relativity fails to reconcile the contradictory principles on which it is based. Rather than combining incompatible assumptions into an integrated whole, the theory allows the adept to step between incompatible assumptions in a way that hides these inconsistencies. The clock paradox is symptomatic of Einstein's failure, and its purported resolution is illustrative of the techniques that can be used to mask this failure. To uncover to the logical contradictions in the theory of relativity presents no very difficult task. However, the theory is impervious to such attacks as it is shielded by a professional constituency of supporters whose interests and authority are bound up in maintaining its inflated claims. Relativity theory, in short, is an ideology." http://www.worldnpa.org/pdf/abstracts/abstracts_215.pdf Herbert Dingle: "The special relativity theory requires different rates of ageing to result from motion which belongs no more to one twin than to the other: that is impossible. It is impossible to exaggerate the importance of this result, for this theory is, by common consent, "taken for granted" in Max Born's words, in all modern atomic research. and it determines the course of practically all current developments in physical science, theoretical and experimental, whether concerned with the laboratory or with the universe. To continue to use the theory without discrimination, therefore, is not only to follow a false trail in the investigation of nature, but also to risk physical disaster on the unforeseeable scale... (...) But it is now clear that the interpretation of those [Lorentz] equations as constituting a basis for a new kinematics, displacing that of Galileo and Newton, which is the essence of the special relativity theory, leads inevitably to impossibilities and therefore cannot be true. Either there is an absolute standard of rest - call it the ether as with Maxwell. or the universe as with Mach, or absolute space as with Newton, or what you will or else ALL MOTION, INCLUDING THAT WITH THE SPEED OF LIGHT, IS RELATIVE, AS WITH RITZ. It remains to be determined, by a valid experimental determination of THE TRUE RELATION OF THE VELOCITY OF LIGHT TO THAT OF ITS SOURCE, which of these alternatives is the true one. In the meantime, the fiction of "space-time" as an objective element of nature, and the associated pseudo-concepts such as "time-dilation", that violate "saving common sense", should be discharged from physics and philosophy..."

ONLY ONE EMISSION THEORY OF LIGHT
http://www.circlon-theory.com/HTML/poundRebka.html
"The Pound-Rebka Experiment is quite complex in its technical details but in principle it is very simple. Photons of a precisely determined wavelength were emitted at the top and bottom of the 22.5-meter-high Jefferson Tower on the Harvard campus. When the photons from the top of the tower were measured at the bottom, their wavelengths were decreased (blue-shifted) by a small amount; and when photons from the bottom were measured at the top, their wavelengths were increased (red- shifted) by the same amount. Proponents of the theory of General Relativity offer three different conflicting explanations of these results that are said to be equivalent to each other and therefore all equally correct. (...) In the drawing of tower #1, the photons are emitted with a wavelength of exactly one (=1). As they travel through the proposed gravitational "field" at the constant velocity of C, they interact with it so that the descending photons acquire mass, momentum and energy from the field and the ascending photons transfer mass, momentum and energy to the field. Thus the intrinsic wavelengths of the photons gradually change as they move through the field. The main problem with this explanation lies in the conceptualization of a physical process by which mass, momentum and energy could be either added to or subtracted from a photon without changing its velocity or angular momentum. (...) In the drawing of tower #2, the photons are emitted at a wavelength of exactly one (=1) that remains constant as they move through the gravitational "field." However, as they move thorough this field, the photons "fall" toward the earth like any other material body, so that the descending photons move at speeds increasingly greater than C, and the ascending photons move at decreasing speeds of less than C. During their time of travel (t=22.5/C=7.5052x10^(-8)s) the ascending photons slow their velocity by (v=gt=.000000736m/s) and the descending photons increase their velocity to C+.000000736m/s. The red and blue shifts are Doppler shifts in which both source and observer are in the same inertial reference frame and each photon is in a different inertial reference frame. The shifts occur because the ascending photons arrive at the observer at a relative velocity of less than C and the descending photons arrive at a velocity greater than C. This change in the photons' velocity will produce shifts in their wavelengths of the measured value of 2.5x10^(-15). (...) In the drawing of tower #3, it is proposed that gravity causes clocks at the bottom of the tower to run slower than clocks at the top. This causes the emitter to take more time to produce a photon and thus increase its wavelength by 2.5 x 10^(-15). The faster clock at the top of the tower makes the emitter produce its photons in shorter time intervals and with shorter wavelengths. While all photons move at exactly C in this example, the observer at the top of the tower would measure their velocity to be less than C and the observer at the bottom of the tower would measure their velocity to be greater than C. This is due to their clocks running at different rates." Einsteiniana's three-equivalent-and-equally-correct-explanations camouflage has an Achilles heel: The second explanation ("the photons "fall" toward the earth like any other material body") is given by Newton's emission theory and contradicts Einstein's theory. Einstein's general relativity predicts that, as photons "fall" toward the earth, their acceleration is two times greater than the acceleration of other material bodies: http://www.speed-light.info/speed_of_light_variable.htm "Einstein wrote this paper in 1911 in German. 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." 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." Therefore, the Pound-Rebka experiment confirmed Newton's emission theory of light and refuted Einstein's general relativity. Pentcho Valev |

ONLY ONE EMISSION THEORY OF LIGHT
The thorny path towards Newton's emission theory of light:
http://www.fqxi.org/community/articles/display/148 "Many physicists argue that time is an illusion. Lee Smolin begs to differ. (...) Smolin wishes to hold on to the reality of time. But to do so, he must overcome a major hurdle: General and special relativity seem to imply the opposite. In the classical Newtonian view, physics operated according to the ticking of an invisible universal clock. But Einstein threw out that master clock when, in his theory of special relativity, he argued that no two events are truly simultaneous unless they are causally related. If simultaneity - the notion of "now" - is relative, the universal clock must be a fiction, and time itself a proxy for the movement and change of objects in the universe. Time is literally written out of the equation. Although he has spent much of his career exploring the facets of a "timeless" universe, Smolin has become convinced that this is "deeply wrong," he says. He now believes that time is more than just a useful approximation, that it is as real as our guts tell us it is - more real, in fact, than space itself. The notion of a "real and global time" is the starting hypothesis for Smolin's new work, which he will undertake this year with two graduate students supported by a $47,500 grant from FQXi."

Lee Smolin is by no means the cleverest Einsteinian - he does not even know that Newton's emission theory of light predicts light deflection in a gravitational field: http://streamer.perimeterinstitute.c...c-4d44d3d16fe9 Lee Smolin: "Newton's theory predicts that light goes in straight lines and therefore if the star passes behind the sun, we can't see it. Einstein's theory predicts that light is bent...." However John Norton IS the cleverest Einsteinian and if he goes towards Newton's emission theory of light, then all Einsteinians should go in that direction: http://www.newscientist.com/article/...erse-tick.html "It is still not clear who is right, says John Norton, a philosopher based at the University of Pittsburgh, Pennsylvania. Norton is hesitant to express it, but his instinct - and the consensus in physics - seems to be that space and time exist on their own. The trouble with this idea, though, is that it doesn't sit well with relativity, which describes space-time as a malleable fabric whose geometry can be changed by the gravity of stars, planets and matter." http://www.humanamente.eu/PDF/Issue13_Paper_Norton.pdf John Norton: "It is common to dismiss the passage of time as illusory since its passage has not been captured within modern physical theories. I argue that this is a mistake. Other than the awkward fact that it does not appear in our physics, there is no indication that the passage of time is an illusion. (...) The passage of time is a real, objective fact that obtains in the world independently of us. How, you may wonder, could we think anything else? One possibility is that we might think that the passage of time is some sort of illusion, an artifact of the peculiar way that our brains interact with the world. Indeed that is just what you might think if you have spent a lot of time reading modern physics. Following from the work of Einstein, Minkowski and many more, physics has given a wonderfully powerful conception of space and time. Relativity theory, in its most perspicacious form, melds space and time together to form a four- dimensional spacetime. The study of motion in space and all other processes that unfold in them merely reduce to the study of an odd sort of geometry that prevails in spacetime. In many ways, time turns out to be just like space. In this spacetime geometry, there are differences between space and time. But a difference that somehow captures the passage of time is not to be found. There is no passage of time." Pentcho Valev |

ONLY ONE EMISSION THEORY OF LIGHT
Einsteinians know no limits when it comes to camouflaging the
falsehood of Einstein's 1905 constant-speed-of-light postulate and extracting career and money from some variable-speed-of-light "heresy" at the same time: http://www.fqxi.org/community/articles/display/150 "If we give up the idea that time exists and the speed of light is constant at the fundamental level, then we could find a theory of quantum gravity. (...) Merging the vastly different laws that govern the macro and the micro has been a huge challenge for physics. Now, John Donoghue, a physicist at the University of Massachusetts, Amherst, thinks he may have the answer. Perhaps, he argues, the familiar view of spacetime as a four-dimensional fabric, which we inherited from Einstein, is not fundamental, but only emerges on large scales - just like our picture of a solid and symmetrical Rubik's cube disappears and re-appears depending on the perspective that we look at it. If he is correct, physicists may have to rethink one of their more cherished beliefs: that the speed of light has always been constant. Donoghue is aware that his idea of a varying universal speed limit - famously set by Einstein over a century ago - goes against the physics' grain. "This is a very nonstandard idea," he admits. "It would really change 99.9 per cent of physics research." However, there's good reason to think that our understanding of spacetime and, in turn, the speed of light, may need to be rewritten."

The Champions: http://www.amazon.com/Faster-Than-Sp.../dp/0738205257 Joao Magueijo: "I am by profession a theoretical physicist. By every definition I am a fully credentialed scholar-graduate work and Ph.D. at Cambridge, followed by a very prestigious research fellowship at St. John's College, Cambridge (Paul Dirac and Abdus Salam formerly held this fellowship), then a Royal Society research fellow. Now I'm a lecturer (the equivalent of a tenured professor in the United States) at Imperial College. (...) A missile fired from a plane moves faster than one fired from the ground because the plane's speed adds to the missile's speed. If I throw something forward on a moving train, its speed with respect to the platform is the speed of that object plus that of the train. You might think that the same should happen to light: Light flashed from a train should travel faster. However, what the Michelson-Morley experiments showed was that this was not the case: Light always moves stubbornly at the same speed. This means that if I take a light ray and ask several observers moving with respect to each other to measure the speed of this light ray, they will all agree on the same apparent speed! (...) The rest of my research work was going well, though, and a year or so later I was overjoyed to find that I had been awarded a Royal Society fellowship. This fellowship is the most desirable junior research position available in Britain, perhaps anywhere. It gives you funding and security for up to ten years as well as the freedom to do whatever you want and go wherever you want. At this stage, I decided that I had had enough of Cambridge, and that it was time to go somewhere different. I have always loved big cities, so I chose to go to Imperial College, in London, a top university for theoretical physics." http://roychristopher.com/joao-mague...tier-cosmology "Likewise, Joao Magueijo has radical ideas, but his ideas intend to turn that Einsteinian dogma on its head. Magueijo is trying to pick apart one of Einstein's most impenetrable tenets, the constancy of the speed of light. This idea of a constant speed (about 3×106 meters/ second) is familiar to anyone who is remotely acquainted with modern physics. It is known as the universal speed limit. Nothing can, has, or ever will travel faster than light. Magueijo doesn't buy it. His VSL (Varying Speed of Light) presupposes a speed of light that can be energy or time-space dependent. Before you declare that he's out of his mind, understand that this man received his doctorate from Cambridge, has been a faculty member at Princeton and Cambridge, and is currently a professor at Imperial College, London." http://www.lauralee.com/news/relativitychallenged.htm Question: Jumping off a bandwagon is risky - surely you could have committed career suicide by suggesting something as radical as a variable speed of light? Magueijo: That's true. Maybe I wouldn't have been so carefree if I hadn't had this Royal Society fellowship: it gives a safety net for 10 years. You can go anywhere and do whatever you want as long as you're productive. Question: So you're free to be the angry young man of physics? Magueijo: Maybe it comes across that I'm bitter and twisted, but if you're reading a book, the body language is lost. You're talking to me face to face: you can see I'm really playing with all this. I'm not an angry young man, I'm just being honest. There's no hard feelings. I may say offensive things, but everything is very good natured. Question: So why should the speed of light vary? Magueijo: It's more useful to turn that round. The issue is more why should the speed of light be constant? The constancy of the speed of light is the central thing in relativity but we have lots of problems in theoretical physics, and these probably result from assuming that relativity works all the time. Relativity must collapse at some point... http://query.nytimes.com/gst/fullpag...pagewanted=all "As propounded by Einstein as an audaciously confident young patent clerk in 1905, relativity declares that the laws of physics, and in particular the speed of light -- 186,000 miles per second -- are the same no matter where you are or how fast you are moving. Generations of students and philosophers have struggled with the paradoxical consequences of Einstein's deceptively simple notion, which underlies all of modern physics and technology, wrestling with clocks that speed up and slow down, yardsticks that contract and expand and bad jokes using the word ''relative.''......''Perhaps relativity is too restrictive for what we need in quantum gravity,'' Dr. Magueijo said. ''We need to drop a postulate, perhaps the constancy of the speed of light.'' http://www.hawking.org.uk/index.php?...64&It emid=66 Stephen Hawking: "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." http://205.188.238.109/time/time100/...of_rela6a.html Stephen Hawking: "So if you were traveling in the same direction as the light, you would expect that its speed would appear to be lower, and if you were traveling in the opposite direction to the light, that its speed would appear to be higher. Yet a series of experiments failed to find any evidence for differences in speed due to motion through the ether. The most careful and accurate of these experiments was carried out by Albert Michelson and Edward Morley at the Case Institute in Cleveland, Ohio, in 1887......It was as if light always traveled at the same speed relative to you, no matter how you were moving." 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://www.rense.com/general13/ein.htm Einstein's Theory Of Relativity Must Be Rewritten By Jonathan Leake, Science Editor The Sunday Times - London "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. "It is becoming increasingly likely that the rules we had thought were fundamental through time and space are actually just bylaws for our bit of it," said Rees, whose new book, Our Cosmic Habitat, is published next month. "Creation is emerging as even stranger than we thought." 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. There is growing evidence that light moved much faster during the early stages of our universe. 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." Pentcho Valev |
