Max Tegmark: "Observed properties of speed of light. Does speed depend on motion of source? No! Does speed depend on motion of observer (frame)? No! Does c depend on source motion? Does speed of a bullet depend on speed of rifle? Does sound speed of a gun shot depend on speed of rifle? Binary stars provide great test. If velocities add, then... You'd see things moving backward in time. Answer: No dependence on source motion observed (and should be dramatic). Does c depend on observer motion (frame)? No 1st order effect had been seen. Michelson-Morley experiment hammered it. But they saw no fringe shift at all! So c appears not to depend on frame." http://ocw.mit.edu/courses/physics/8-033-relativity-fall-2006/readings/symmetry.pdf

Max Tegmark: "We all believe in relativity, relativity, relativity. Yes we all believe in relativity, relativity, relativity. Everything is relative, even simultaneity, and soon Einstein's become a de facto physics deity. 'cos we all believe in relativity, relativity, relativity. We all believe in relativity, relativity, relativity. Yes we all believe in relativity, relativity, relativity." https://www.youtube.com/watch?v=5PkLLXhONvQ

In their early education Einsteinians are told various idiocies, repeatedly, until in the end they become indistinguishable from Bingo the Clowno:

Bingo the Clowno

Here is a clear example of the conversion of normal people into thoughtless Bingos: Initially Joe Wolfe's students are sure that the speed of light cannot be the same for differently moving observers but in the end all of them get the name Bingo the Einsteiniano:

Joe Wolfe: "At this stage, many of my students say things like "The invariance of the speed of light among observers is impossible" or "I can't understand it". Well, it's not impossible. It's even more than possible, it is true. This is something that has been extensively measured, and many refinements to the Michelson and Morley experiment, and complementary experiments have confirmed this invariance to very great precision. As to understanding it, there isn't really much to understand. However surprising and weird it may be, it is the case. It's the law in our universe. The fact of the invariance of c doesn't take much understanding."

 Even when you use an insult you manage to demonstrate how pathetically stupid and childish you are.

 Bingo the Einsteiniano, professor of physics at the University of California, Davis. A synopsis of his teaching: The speed of light is constant by definition. Einstein said the speed of light is variable in a gravitational field - an interpretation which is "perfectly valid and makes good physical sense" - but after Einstein the speed of light in a gravitational field became constant. So constant that "it does not even make any sense to say that it varies". On the other hand, "light falls with twice the acceleration of ordinary slow matter": http://www.desy.de/user/projects/Physics/Relativity/SpeedOfLight/speed_of_light.html Steve Carlip: "Is c, the speed of light in vacuum, constant? At the 1983 Conference Generale des Poids et Mesures, the following SI (Systeme International) definition of the metre was adopted: The metre is the length of the path travelled by light in vacuum during a time interval of 1/299 792 458 of a second. This defines the speed of light in vacuum to be exactly 299,792,458 m/s. This provides a very short answer to the question "Is c constant": Yes, c is constant by definition! [...] Einstein went on to discover a more general theory of relativity which explained gravity in terms of curved spacetime, and he talked about the speed of light changing in this new theory. In the 1920 book "Relativity: the special and general theory" he wrote: "...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 [...] 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." Since Einstein talks of velocity (a vector quantity: speed with direction) rather than speed alone, it is not clear that he meant the speed will change, but the reference to special relativity suggests that he did mean so. This interpretation is perfectly valid and makes good physical sense, but a more modern interpretation is that the speed of light is constant in general relativity. [...] Finally, we come to the conclusion that the speed of light is not only observed to be constant; in the light of well tested theories of physics, it does not even make any sense to say that it varies." http://arxiv.org/pdf/gr-qc/9909014v1.pdf Steve Carlip: "It is well known that the deflection of light is twice that predicted by Newtonian theory; in this sense, at least, light falls with twice the acceleration of ordinary "slow" matter."

 >>>Does sound speed of a gun shot depend on speed of rifle? If an airplane travels with velocity - v - relative to earth's surface =====> then the sound speed of a gun - inside the airplane - relative to earth's surface - must depend on the direction - in which that gun is pointing - relative to the velocity vector of the airplane.

If an airplane travels with velocity - v - relative to earth's surface =====> then the LIGHT speed of a TORCH - inside the airplane - relative to earth's surface - must depend on the direction - in which that TORCH is pointing - relative to the velocity vector of the airplane.

 The breathtaking logic of Professor Bingo the Einsteiniano: Leonard Susskind (10:26) : "The principle of relativity is that the laws of physics are the same in every reference frame. That principle existed before Einstein. Einstein added one law of physics - the law of physics is that the speed of light is the speed of light, c. If you combine the two things together - that the laws of physics are the same in every reference frame, and that it's a law of physics that light moves with certain velocity, you come to the conclusion that light must move with the same velocity in every reference frame. Why? Because the principle of relativity says that the laws of physics are the same in every reference frame, and Einstein announced that it is a law of physics that light moves with a certain velocity." https://www.youtube.com/watch?v=toGH5BdgRZ4 This particular idiocy - that Einstein's 1905 second postulate is a consequence of the first - was introduced by Einstein himself so it is sacred and other Bingos teach it as well: Dave Slaven: "Einstein's first postulate seems perfectly reasonable. And his second postulate follows very reasonably from his first. How strange that the consequences will seem so unreasonable." http://webs.morningside.edu/slaven/Physics/relativity/relativity3.html Lubos Motl: "The second postulate of special relativity morally follows from the first one once you promote the value of the speed of light to a law of physics which is what Einstein did. In classical Newtonian mechanics, it was not a law of physics." http://motls.blogspot.com/2006/12/lorentz-violation-and-deformed-special.html Professor Raymond Flood (5:05): "A consequence of Einstein's principle of relativity is that the speed of light in a vacuum has the same value in two uniformly moving frames of reference." https://www.youtube.com/watch?v=IjRSYv7u3T4 Chad Orzel: "The core idea of Einstein's theory of relativity can fit on a bumper sticker: The Laws Of Physics Do Not Depend On How You're Moving. Absolutely everything else follows from the simple realization that physics must appear exactly the same to person in motion as to a person at rest - the constant speed of light, the slowing of time for moving observers, E=mc2, black holes, even the expanding universe (I've written a whole book about this, explained through imaginary conversations with my dog)." http://www.forbes.com/sites/chadorzel/2015/05/29/four-reasons-to-not-fear-physics/ Michael Fowler: "Therefore, demanding that the laws of physics are the same in all inertial frames implies that the speed of any light wave, measured in any inertial frame, must be 186,300 miles per second. This then is the entire content of the Theory of Special Relativity: the Laws of Physics are the same in any inertial frame, and, in particular, any measurement of the speed of light in any inertial frame will always give 186,300 miles per second." http://galileo.phys.virginia.edu/classes/109/lectures/spec_rel.html Vesselin Petkov: "One of the fundamental facts of modern physics is the constancy of the speed of light. Einstein regarded it as one of the two postulates on which special relativity is based. So far, however, little attention has been paid to the status of this postulate when teaching special relativity. It turns out that the constancy of the speed of light is a direct consequence of the relativity principle, not an independent postulate. To see this let us consider the two postulates of special relativity as formulated by Einstein in his 1905 paper "On the electrodynamics of moving bodies": "the same laws of electrodynamics and optics will be valid for all frames of reference for which the equations of mechanics hold good. We will raise this conjecture (the purport of which will hereafter be called the "Principle of Relativity") to the status of a postulate, and also introduce another postulate, which is only apparently irreconcilable with the former, namely, that light is always propagated in empty space with a definite velocity c which is independent of the state of the motion of the emitting body". As the principle of relativity states that "the laws of physics are the same in all inertial reference frames" and the constancy of the speed of light means that "the speed of light is the same in all inertial reference frames (regardless of the motion of the source or the observer)" it follow that the second postulate is indeed a consequence of the first - the law describing the propagation of light is the same for all inertial observers." http://arxiv.org/abs/gr-qc/9909081 Pentcho Valev

 Professor Bingo the Einsteiniano teaches that, constant or variable, the speed of light is irrelevant - it cannot diminish the greatness of Divine Albert's Divine Theory: Jean-Marc Lévy-Leblond: "Il se pourrait même que de futures mesures mettent en évidence une masse infime, mais non-nulle, du photon ; la lumière alors n'irait plus à la "vitesse de la lumière", ou, plus précisément, la vitesse de la lumière, désormais variable, ne s'identifierait plus à la vitesse limite invariante. Les procédures opérationnelles mises en jeu par le "second postulat" deviendraient caduques ipso facto. La théorie elle-même en serait-elle invalidée ? Heureusement, il n'en est rien..." http://o.castera.free.fr/pdf/Chronogeometrie.pdf Jean-Marc Levy-Leblond: "The evidence of the nonzero mass of the photon would not, as such, shake in any way the validity of the special relalivity. It would, however, nullify all its derivations which are based on the invariance of the photon velocity." http://o.castera.free.fr/pdf/One_more_derivation.pdf Most idiocies taught in Einstein's schizophrenic world are devised by Einstein himself but this one is not - it seems that Jean-Marc Levy-Leblond is the author. Yet Einsteinians love it and teach it with enthusiasm: Sabine Hossenfelder: "If photons had a restmass, special relativity would still be as valid as it's always been. The longer answer is that the invariance of the speed of light features prominently in the popular explanations of special relativity for historic reasons, not for technical reasons. Einstein was lead to special relativity contemplating what it would be like to travel with light, and then tried to find a way to accommodate an observer's motion with the invariance of the speed of light. But the derivation of special relativity is much more general than that, and it is unnecessary to postulate that the speed of light is invariant." http://backreaction.blogspot.bg/2016/05/dear-dr-b-if-photons-have-mass-would.html Tom Roberts: "If it is ultimately discovered that the photon has a nonzero mass (i.e. light in vacuum does not travel at the invariant speed of the Lorentz transform), SR would be unaffected but both Maxwell's equations and QED would be refuted (or rather, their domains of applicability would be reduced)." http://groups.google.ca/group/sci.physics.relativity/msg/dc1ebdf49c012de2 Mitchell J. Feigenbaum: "In this paper, not only do I show that the constant speed of light is unnecessary for the construction of the theories of relativity, but overwhelmingly more, there is no room for it in the theory." http://arxiv.org/PS_cache/arxiv/pdf/0806/0806.1234v1.pdf Tom Roberts: "As I said before, Special Relativity would not be affected by a non-zero photon mass, as Einstein's second postulate is not required in a modern derivation (using group theory one obtains three related theories, two of which are solidly refuted experimentally and the third is SR). So today's foundations of modern physics would not be threatened." http://groups.google.com/group/sci.physics.research/msg/44d3ebf3b94d89ad New Scientist: "...a photon with mass would not necessarily always travel at the same speed. Feigenbaum's work shows how, contrary to many physicists' beliefs, this need not be a problem for relativity." http://www.newscientist.com/article/mg20026801.500-why-einstein-was-wrong-about-relativity.html Pentcho Valev

 >>>so you are saying lightspeed isn't constant? Amigo>Yes. Ok I think the Einsteinians/relativists try to hide that by bodging their maths and making mistakes . what "they" seem to do is: 1. claim there is no preferred frame BUT.. 2. when "they" do the twin paradox the twin that travels has the slower clock, not the stay-at-home twin. So... 3. that means the stay-at-home twin is in a preferred frame despite their denials at (1) thus... 4. setting the clocks to run as per the stay-at-home twin would mean lightspeed was variable and the times t and t' were the same! i.e... 5. recovered lightspeed in the way it should be treated.
