There is so much panic in Einstein criminal cult that PHYSORG, a group
of zombies responsible for propaganda, published the following idiocy: http://www.physorg.com/news114010680.html "The first measurement of Einstein's time dilation took place in 1938, when US scientists used the Doppler effect -- the change in pitch when a sound and the person hearing it are moving apart or closer together -- as the measuring tool." A slightly less idiotic reference to the same experiment is given he http://www.mpi-hd.mpg.de/ato/rel/ "The first experimental proof of time dilation was performed by Ives and Stilwell [1] by measuring the Doppler-shifted frequencies of an emission line in hydrogen canal rays in parallel and antiparallel direction. The respective resonance conditions are given by the relativistic Doppler-formula, which is a direct consequence of time dilation." The problem is whether the Doppler shift is due to time dilation or not. Perhaps it is due to the fact that the speed of light varies with the relative speed of the light source and the observer? Those who wish to know the answer should first solve an analogous problem: Is the gravitational redshift due to gravitational time dilation or is it due to the fact that the speed of light varies with the gravitational potential?

That's easy, go to the library, find the published paper, check their working, repeat the calculations assuming changing light speed, compare the results. If it works, you then need to find there's no research showing that light speed doesn't change in that kind of situation. Armed with this justification, perform a suitable experiment to show the speed really is changing. Finally, fill in the application form to claim your Nobel prize. It might take a few years, but if you're sure you're right, it will be worth the effort don't you think? However if you don't really believe yourself, if you're just doing it for the anti-establishment buzz it gives you, then you will never find the motivation to do more than blab about it. |

No because Divine Albert has already solved half of the problem (in fact the whole problem) in 1911: http://www.blazelabs.com/f-g-gcont.asp "The first confirmation of a long range variation in the speed of light travelling in space came in 1964. Irwin Shapiro, it seems, was the first to make use of a previously forgotten facet of general relativity theory -- that the speed of light is reduced when it passes through a gravitational field....Faced with this evidence, Einstein stated:"In the second place our result shows that, according to the general theory of relativity, the law of the constancy of the velocity of light in vacuo, which constitutes one of the two fundamental assumptions in the special theory of relativity and to which we have already frequently referred, cannot claim any unlimited validity. A curvature of rays of light can only take place when the velocity of propagation of light varies with position."......Today we find that since the Special Theory of Relativity unfortunately became part of the so called mainstream science, it is considered a sacrilege to even suggest that the speed of light be anything other than a constant. This is somewhat surprising since even Einstein himself suggested in a paper "On the Influence of Gravitation on the Propagation of Light," Annalen der Physik, 35, 1911, that the speed of light might vary with the gravitational potential. Indeed, the variation of the speed of light in a vacuum or space is explicitly shown in Einstein's calculation for the angle at which light should bend upon the influence of gravity. One can find his calculation in his paper. The result is c'=c(1+V/c^2) where V is the gravitational potential relative to the point where the measurement is taken. 1+V/c^2 is also known as the GRAVITATIONAL REDSHIFT FACTOR." http://www.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.bnl.gov/community/Tours/E.../Einsteine.jpg http://www.physicstoday.org/vol-58/i...e_einstein.mp3 Pentcho Valev |

But the fact that the "speed" (really velocity) of light is constant,
independent of the motions of the source and the receiver, is one of the most firmly established principles of science. But ---- what is the light moving relative to???????? |

The source, of course. The fiction that the "speed" (really velocity) of light is constant, independent of the motions of the source and the receiver, is one of the stupidest unestablished loads of crap in Nature. The truth is: every measurement of c yields the same value. Nobody has ever measured something different (within error bars) and nobody says: velocity IS constant (or not), everybody nowadays refers to what one measures, except Androcles, that fisherman in the sea of wisdom with his broken fishing rod. Androcles is the stupidest established crackpot in the Universe. ahahaaa........except hanson, pentcho, traveler, ahahhaaa, there is actually no stupidest one, they outdo each other every other day. w.

Then what are you moaning about? You should be using your energy to promote public understanding of GR. If you don't think GR applies here, and are saying that there's in fact a new mechanism which is unknown in the literature, then see my previous response about solving the problem yourself. |

You should be using your energy to promote public understanding of GR. Let us say it this way: Einstein 1911 equation c'=c(1+V/c^2) describing how the speed of light varies with the gravitational potential is CORRECT: 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].

However the fact that Einstein's 1911 equation c'=c(1+V/c^2) is CORRECT implies that, as your masters measure the gravitational redshift and e.g. confirm Pound and Rebka's result f'=f(1+V/c^2), they in fact measure the variability of the speed of light and confirm Einstein's 1911 equation c'=c(1+V/c^2). They do not confirm any gravitational time dilation. Equivalently, the Doppler effect confirms the prediction of Newton's emission theory of light c'=c+v, where v is the relative speed of the light source and the observer. Again no time dilation. Now see what your masters and their sycophants teach: http://sciencenow.sciencemag.org/cgi...ll/2007/1113/2 "Special relativity joins space and time into a single weird thing called spacetime that appears different to observers moving relative to each other. Imagine you hold a firecracker in each of your outstretched hands and you see the two go off simultaneously. (Ouch!) Bizarrely, another person zooming by at near-light speed will see the firecrackers explode at different times. (She'll also claim your arms are shorter than you say they are.) In much the same way, a clock flying at near-light speed would tick more slowly than the watch on your wrist, and a person who travels through space in a high-speed rocket would appear to age unusually slowly to someone stuck on Earth. Such "time dilation" seems preposterous. But in 1907, Einstein proposed an experiment to test the idea. Atoms and ions give off light of specific colors. Light is a kind of rippling wave, and the rate of rippling can be viewed essentially as the ticking of a clock. Einstein reasoned that if the ion were accelerated to near-light speed, time would slow for it and, hence, so would the rippling of the emitted light waves. That is, the speeding ions would emit light of a lower frequency. Now, Gerald Gwinner, a physicist at the University of Manitoba in Winnipeg, Canada, and colleagues have tested time dilation in just this way." Pentcho Valev |

Then show it formally. Don't just throw equations around, nobody can even understand that, let alone believe it. What are these measurements of gravitational redshift? Why don't you dig up the raw data and analyse it according to what you think is correct and see what comes out. You can't make a conculsion without doing any analysis. |
