All truth passes through three stages. First, it is ridiculed. Second, it is violently opposed. Third, it is accepted as being self-evident: Arthur Schopenhauer -- In questions of science the authority of a thousand is not worth the humble reasoning of a single individual: Galileo Galilei -- Science is a wonderful thing if one does not have to earn one's living at it: Albert Einstein -- When you have eliminated the impossible, what ever remains, however improbable must be the truth: Sir Arthur Conan Doyle -- We all agree that your theory is crazy, but is it crazy enough? Niels Bohr -- Whenever a true theory appears, it will be its own evidence. Its test is that it will explain all phenomena: Ralph Waldo Emerson -- Since the mathematicians invaded Relativity, I do not understand it myself anymore: Albert Einstein -- I would say that the aether is a medium invented by man for the purpose of propagating his misconceptions from one place to another: W.F.G. Swann: -- Most of the fundamental ideas of science are essentially simple, and may, as a rule, be expressed in a language comprehensible to everyone: Albert Einstein -- Physics is mathematical not because we know so much about the physical world, but because we know so little: Bertrand Russell -- If I could explain it to the average person, I would not have been worth the Nobel Prize: R. P. Feynman -- I do not feel obliged to believe that the same God who has endowed us with sense, reason, and intellect has intended us to forgo their use: Galileo Galilei -- How dare we speak of the laws of chance? Is not chance the antithesis of all law?: Bertrand Russell -- Only two things are infinite, the universe and human stupidity, and I´m not sure about the former: Albert Einstein -- The glory of mathematics is that you don't have to say what you are talking about: Richard Feynman -- Anything is possible if you don´t know what you are talking about: Author Unknown -- In life, everything is relative - except Einstein´s theory: Leonid S. Sukhorukov -- Don´\'t worry about people stealing your ideas. If your ideas are any good, you´ll have to ram them down people´s throats: Howard Aiken --A day will come undoubtedly when the ether will be discarded as useless: H. Poincaré -- First they tell you you´re wrong and they can prove it; then they tell you you´re right but it isn´t important; then they tell you it´s important but they knew it all along: Charles Kettering -- It is not once nor twice but times without number that the same ideas make their appearance in the world: Aristotle -- The opposite of a true statement is a false statement. The opposite of a profound truth may well be another profound truth: Niels Bohr -- A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it: Max Planck -- Euclid taught me that without assumptions there is no proof. Therefore, in any argument, examine the assumptions: Eric Temple Bell -- Half this game is ninety percent mental: Yogi Berra

The velocity of light c, relative to the source, is a vector of constant magnitude. The velocity relative to an observer moving with velocity v, is c – v. The magnitude of the relative velocity depends on the magnitude and direction of motion of observer. It is shown that the fringe shifts produced by the MM and Sagnac experiments, and that the frequency shift by the Doppler Effect, are contrary to the principle of constancy of speed of light.


Nanda Ballabh Pant(BAIJNATH, India):
It is a superb and comparative consolidation of many phenomena in one article. However, in case of
light to explain Doppler effect one states that with motion frequency and wavelength of observed light changes so (and therefore change in signal color) that the velocity of light remains unchanged. But in contrast to this there is doubly special relativity (D Harris: After Einstein, New Scientist8 February 2003) according to which velocity of light depends on the energy of its quantum that ishigher the energy of light quantum more is its speed in comparison low energy photon. However, this difference is too small to be detected experimentally. To translate this into reality one is looking for
Greisen-Zatsepin -Kuzmin limit according to which if special relativity is correct than on the earth,
there should not be any cosmic ray particles left with higher energies than 5×1019 electron volts and vice versa. However, cosmological observations are also not free from ambiguity. The possibility of tachyons existence as well as formation of a black hole is ruled out if one considers the velocity of light is constant as statistical measure, because if one wants to measure the velocity of single photon (light quantum) ; according to uncertainty relation one cannot measure that precisely for particular instant. As R P Feynman et al ( R. P. Feynman, QED: The strange theory of light and matter, 1985) says “It may surprise you that there is an amplitude for a photon to go at speeds faster or slower than the conventional speed, c, but these amplitudes cancel out over long distances.” The very fundamental question is what does resist to the velocity of light to be it the limiting (invariant) speed of fastest signals even in the vacuum? Answer lies itself in the milieu of the vacuum (fabric of space-time) which by resisting least to the light quanta as per their energies provides terminal velocity to those as the fastest possible traveling signals. Thus the background (here the milieu of the vacuum which is better defined as the state of lowest energy with a nonzero value) has its role not only to the material particles but also to the light quanta.

We need experimental proof to refute that postulate once and for all.

The Michelson-Morley and Sagnac experimentsand Dopper Effect are refutations of the principle of constancy of speed of light relative to an observer.
