quote:Originally posted by DocNI believe Einstein did try to disprove his theory (SR) based on the constancy of the velocity of light (c) but gave up on this project. Later in his life, he did try to disprove some of his own theories. So that is the way of science.Doc

quote:Originally posted by daveshortsOk, the article points out that there is a big problem persuading physics graduates to teach the subject. This problem is sociogical rather than fundamental to the subject. What is your point?

quote:Originally posted by daveshortsAll the ones I could be bothered to read were about the drop in student numbers dong Physics. I would have thought this has a few causes: Students would rather do something less challenging, biology is more fashionable, the shortage of physicists is causing a shortage of good physics teachers, you can't take things apart to learn how they work any more etc etc. It doesn't mean that there is anything wrong with the theory.

quote:Originally posted by Pentcho ValevVARIABLE SPEED OF LIGHT AND EINSTEIN'S CRIMINAL CULTThe main concern of Einstein's hypnotists is to camouflage the fact that the speed of light does depend on the speed of the light source and therefore Einstein's theory (and modern physics in general) is just a farce. The camouflage involves even simulated fights among hypnotists:...sorry, you cannot view external links. To see them, please REGISTER or LOGINIt is easy to see that hypnotists always discuss the idea of variability of the speed of light in a way that has nothing to do with Einstein's original definition of constancy (the speed of light is independent of the speed of the light source). In fact, in 1911 Einstein showed that in a gravitational field the speed of light is VARIABLE:...sorry, you cannot view external links. To see them, please REGISTER or LOGIN"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. One can do a simple Huyghens reconstruction of a wave front, taking into account the different speed of advance of the wavefront at different distances from the star (variation of speed of light), to derive the deflection of the light by the star. 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 / c2 ) where V is the gravitational potential relative to the point where the speed of light c0 is measured."By applying the equivalence principle one could easily convert Einstein's formula into c' = c + v valid in the absence of a gravitational field, where c is the speed of photons relative to the light source and v is the relative speed of the light source and the observer. Then one could remember Einstein's words: "If the speed of light is the least bit affected by the speed of the light source, then my whole theory of relativity and theory of gravity is false."

quote:Originally posted by Pentcho ValevEINSTEIN'S HYPNOTISTS PROVE 5=4One of Einstein's crucial discoveries is the fact that, if the quantity 1/gamma = (1-v^2/c^2)^(1/2) is replaced by its Taylor approximation 1-v^2/2c^2, Einstein's lies about gravitational time dilation can be camouflaged to some extent. If Einstein had not made this discovery, that is, if the original quantity (1-v^2/c^2)^(1/2) had remained unchanged, the malignancy called relativity theory would not have killed theoretical science (perhaps). Einstein's hypnotists do know about the crucial discovery and always replace (1-v^2/c^2)^(1/2) with 1-v^2/2c^2. Consider Problem 3 "Circular motion", (a) and (b), on p. 15, solution on p. 19, in ...sorry, you cannot view external links.

quote:Originally posted by Pentcho ValevRELATIVITY AND SELF-DESTRUCTIONHowever later Einstein had to camouflage the fact that the frequency shift is due to variable speed of light and introduced gravitational time dilation - a concept extremely dangerous for human rationality. Two identical clocks in identical conditions (identical gravitational fields) allegedly have different rates. Rationality is immediately destroyed and the victim starts worshipping both the miracle and its creator.

quote:Experimental confirmationGravitational time dilation has been experimentally measured using atomic clocks on airplanes. The clocks that traveled aboard the airplanes upon return were slightly fast with respect to clocks on the ground. The effect is significant enough that the Global Positioning System needs to correct for its effect on clocks aboard artificial satellites, providing a further experimental confirmation of the effect.Gravitational time dilation has also been confirmed by the Pound-Rebka experiment, observations of the spectra of the white dwarf Sirius B and experiments with time signals sent to and from Viking 1 mars lander.

He and other quantum gravity theorists are pretty excited by that possibility, which just goes to show what they’re up against."

Einsteinians know Einstein would disagree about "little falsehood". Once he said: "If the speed of light is the least bit affected by the speed of the light source, then my whole theory of relativity and theory of gravity is false." However the solution Einsteinians have found is both elegant and all-embracing: Violations are tiny, axioms are just a little false, Einstein is just a little wrong.
