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.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 Newton's 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...)" Stephen Hawking's logic: PREMISE: The Michelson-Morley experiment proved that the speed of light is independent of the movements of both the emitter and the observer. CONCLUSION: The speed of light is constant in a gravitational field. JOHN MICHELL WAS WRONG. Logic inherent in Newton's emission theory of light: PREMISE: The Michelson-Morley experiment proved that the speed of light varies with v, the relative speed of the emitter and the observer, in accordance with the equation c'=c+v. Confirmations of the emission theory's PREMISE in Einsteiniana: http://www.pitt.edu/~jdnorton/papers/companion.doc John Norton: "These efforts were long misled by an exaggeration of the importance of one experiment, the Michelson-Morley experiment, even though Einstein later had trouble recalling if he even knew of the experiment prior to his 1905 paper. This one experiment, in isolation, has little force. Its null result happened to be fully compatible with Newton's own emission theory of light. Located in the context of late 19th century electrodynamics when ether-based, wave theories of light predominated, however, it presented a serious problem that exercised the greatest theoretician of the day." http://philsci-archive.pitt.edu/1743/2/Norton.pdf John Norton: "In addition to his work as editor of the Einstein papers in finding source material, Stachel assembled the many small clues that reveal Einstein's serious consideration of an emission theory of light; and he gave us the crucial insight that Einstein regarded the Michelson-Morley experiment as evidence for the principle of relativity, whereas later writers almost universally use it as support for the light postulate of special relativity. Even today, this point needs emphasis. The Michelson-Morley experiment is fully compatible with an emission theory of light that CONTRADICTS THE LIGHT POSTULATE." 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." James H. Smith "Introduction à la relativité" EDISCIENCE 1969 pp. 39-41: "Si la lumière était un flot de particules mécaniques obéissant aux lois de la mécanique, il n'y aurait aucune difficulté à comprendre les résultats de l'expérience de Michelson-Morley.... Supposons, par exemple, qu'une fusée se déplace avec une vitesse (1/2)c par rapport à un observateur et qu'un rayon de lumière parte de son nez. Si la vitesse de la lumière signifiait vitesse des "particules" de la lumière par rapport à leur source, alors ces "particules" de lumière se déplaceraient à la vitesse c/2+c=(3/2)c par rapport à l'observateur. Mais ce comportement ne ressemble pas du tout à celui d'une onde, car les ondes se propagent à une certaine vitesse par rapport au milieu dans lequel elles se développent et non pas à une certaine vitesse par rapport à leur source..... Il nous faut insister sur le fait suivant: QUAND EINSTEIN PROPOSA QUE LA VITESSE DE LA LUMIERE SOIT INDEPENDANTE DE CELLE DE LA SOURCE, IL N'EN EXISTAIT AUCUNE PREUVE EXPERIMENTALE." CONCLUSION: The speed of light varies with phi, the gravitational potential difference between the point of emission and the point of reception (observation) of the light, in accordance with the equation c'=c(1+phi/c^2). JOHN MICHELL WAS RIGHT. Pentcho Valev |

JOHN MICHELL WAS RIGHT. The speed of light in a vacuum is always C=3x10^8 meters per second. In General Relativity, time runs at different rates at different locations in a gravity field relative to a fixed point. So, relative to a given location, light's speed can be observed to be different due to gravitational time dilation. + |

For those morons that don't know what a contradiction is, there are no contradictions in the speed of light being c and also c-v simultaneously. |
