DOPPLER EFFECT AGAINST SPECIAL RELATIVITY
As the observer starts moving towards the light source, wavecrests
start hitting him more frequently, that is, relative to the observer, the frequency and the speed of light increase while the wavelength remains constant: http://a-levelphysicstutor.com/wav-doppler.php "vO is the velocity of an observer moving towards the source. This velocity is independent of the motion of the source. Hence, the velocity of waves relative to the observer is c + vO. (...) The motion of an observer does not alter the wavelength. The increase in frequency is a result of the observer encountering more wavelengths in a given time." http://www.expo-db.be/ExposPrecedent...%20Doppler.pdf "La variation de la fréquence observée lorsqu'il y a mouvement relatif entre la source et l'observateur est appelée effet Doppler. (...) 6. Source immobile - Observateur en mouvement: La distance entre les crêtes, la longueur d'onde lambda ne change pas. Mais la vitesse des crêtes par rapport à l'observateur change !" http://www.hep.man.ac.uk/u/roger/PHY.../lecture18.pdf Roger Barlow: "Now suppose the source is fixed but the observer is moving towards the source, with speed v. In time t, ct/(lambda) waves pass a fixed point. A moving point adds another vt/(lambda). So f'=(c +v)/(lambda)." http://www.astrosurf.com/quasar95/exposes/redshift.pdf "Appliqué à la lumière, cet effet Doppler-Fizeau engendre un décalage des fréquences émises par une source en mouvement par rapport à un observateur. Comment expliquer ce phénomène ? Par un exemple simple : Une personne est debout sur le rivage d'un bord de la mer. Des vagues lui arrivent sur les pieds toutes les dix secondes. La personne marche, puis court en direction du large (là où se forment les vagues). Elle va à la rencontre des vagues, celles-ci l'atteignent avec une fréquence plus élevée (par exemple toutes les huit secondes, puis toutes les cinq secondes). La personne fait alors demi-tour et marche puis court en direction de la plage. Les vagues l'atteignent avec une fréquence moins élevée, par exemple toutes les douze, puis quinze secondes. Cette petite démonstration s'applique à une onde physique, comme un son, ou ici les vagues sur l'océan pour une meilleure compréhension. Elle peut être extrapolée à une onde lumineuse, en considérant que le sommet d'une vague est le point d'amplitude maximale de l'onde lumineuse." http://www.eng.uwi.tt/depts/elec/sta...relativity.pdf The Invalidation of a Sacred Principle of Modern Physics Stephan J.G. Gift "For a stationary observer O, the stationary light source S emits light at speed c, wavelength Lo, and frequency Fo given by Fo=c/Lo. If the observer moves toward S at speed v, then again based on classical analysis, the speed of light relative to the moving observer is (c + v) and not c as required by Einstein's law of light propagation. Hence the observer intercepts wave-fronts of light at a frequency fA, which is higher than Fo, as is observed, and is given by fA = (c+v)/Lo Fo. (...) In light of this elementary result invalidating STR, it is difficult to understand why this invalid theory has been (and continues to be) accepted for the past 100 years." Usually Einsteinians don't try to contradict this obviously correct interpretation of the Doppler effect (moving observer) but recently Tom Roberts did (in sci.physics.relativity): http://www.msgarchive.net/showthread...EDSHIFT-LUNACY Tom Roberts: "A child knows that if you angle a ruler relative to the object you are measuring, you will get a different answer for its length than if the ruler is aligned properly -- the orientation of the measuring instrument (relative to the object being measured) affects the value it measures. When measuring the wavelength of a given light ray, the orientation in spacetime of your ruler will affect the value you measure. If you are at rest relative to the source, you will measure the same value of wavelength as an observer at the source; if you are moving away from or toward the source, your ruler's orientation in spacetime will be different from that of an observer at the source, and you will measure a longer or shorter value of the wavelength." http://groups.google.com/group/sci.p...238760facf3fb0 JOHN KENNAUGH: "Perhaps you would like to add to your collection the views of the grate Tom Roberts. Me: If I am 1 ly away from a source of light and I change my speed the observed frequency immediately changes. Accepted theory says that the speed of the light arriving has not changed and is still c. If the speed has not changed and the frequency has then there must be a different wavelength. Tom: Correct so far. Me: The wavelength is a function of the speed of separation of the light at the source 1 ly away. Tom: This is grotesquely wrong. Me: It is absolutely right. Tom: Nonsense. The "speed of separation of the light at the source" is c, a single value. Me: Only in the FoR of the source. Tom: If wavelength were indeed a function of the speed of separation from the source, then all light would necessarily have a single wavelength -- it doesn't. Your basic error is saying "the wavelength", implicitly thinking it is a property of the light; it isn't. It requires an instrument to measure the wavelength of light, and the value obtained depends on properties of the instrument (e.g. its velocity wrt the source of the light). Me: How can the RELATIVE velocity of the source affect my ruler or the clock of my frequency counter? Tom did not respond. _________________________________________ end of John Kennaugh's text Pentcho Valev |

DOPPLER EFFECT AGAINST SPECIAL RELATIVITY

John Norton: "Here's a light wave and an observer. If the observer were to hurry towards the source of the light, the observer would now pass wavecrests more frequently than the resting observer. That would mean that moving observer would find the frequency of the light to have increased (AND CORRESPONDINGLY FOR THE WAVELENGTH - THE DISTANCE BETWEEN CRESTS - TO HAVE DECREASED)." For all other waves, as the observer starts moving towards the wave source, the frequency and the speed of the waves (relative to the observer) increase while the wavelength remains constant. Light waves, however, should behave as John Norton says or else Divine Albert's Divine Theory would collapse and Norton would have to become expert in climate science. Does Norton see this strange lack of analogy between the light wave and all other waves? He doesn't. In less dangerous situations Norton practices doublethink but in this particular case ABSOLUTE CRIMESTOP in the only imperative in Einsteiniana: http://www.liferesearchuniversal.com...html#seventeen George Orwell: "Crimestop means the faculty of stopping short, as though by instinct, at the threshold of any dangerous thought. It includes the power of not grasping analogies, of failing to perceive logical errors, of misunderstanding the simplest arguments if they are inimical to Ingsoc, and of being bored or repelled by any train of thought which is capable of leading in a heretical direction. Crimestop, in short, means protective stupidity." Pentcho Valev |

DOPPLER EFFECT AGAINST SPECIAL RELATIVITY
Einsteinians willingly explain how the light source starting to move
towards the fixed observer changes the wavelength: http://en.wikisource.org/wiki/On_the...f_Relativit y Quirino Majorana 1918: "...let us consider a luminous source S which emits waves of length lambda and of frequency n moving towards the observer fixed at O. If we suppose that the waves are transmitted through a stationary ether... (...) As regards the frequency we arrive, therefore, at the same conclusions (...) whether we adopt the ethereal or the ballistic hypothesis; but for the wave-length we obtain different values from the two hypotheses..." [The ethereal hypothesis predicts VARIABLE wavelength, the ballistic hypothesis CONSTANT wavelength.] http://www.amazon.com/Brief-History-.../dp/0553380168 Stephen Hawking, "A Brief History of Time", Chapter 3: "In the 1920s, when astronomers began to look at the spectra of stars in other galaxies, they found something most peculiar: there were the same characteristic sets of missing colors as for stars in our own galaxy, but they were all shifted by the same relative amount toward the red end of the spectrum. To understand the implications of this, we must first understand the Doppler effect. As we have seen, visible light consists of fluctuations, or waves, in the electromagnetic field. The wavelength (or distance from one wave crest to the next) of light is extremely small, ranging from four to seven ten-millionths of a meter. The different wavelengths of light are what the human eye sees as different colors, with the longest wavelengths appearing at the red end of the spectrum and the shortest wavelengths at the blue end. Now imagine a source of light at a constant distance from us, such as a star, emitting waves of light at a constant wavelength. Obviously the wavelength of the waves we receive will be the same as the wavelength at which they are emitted (the gravitational field of the galaxy will not be large enough to have a significant effect). Suppose now that the source starts moving toward us. When the source emits the next wave crest it will be nearer to us, so the distance between wave crests will be smaller than when the star was stationary. This means that the wavelength of the waves we receive is shorter than when the star was stationary. Correspondingly, if the source is moving away from us, the wavelength of the waves we receive will be longer. In the case of light, therefore, means that stars moving away from us will have their spectra shifted toward the red end of the spectrum (red-shifted) and those moving toward us will have their spectra blue- shifted." Einsteinians always forget to add that the mechanism is not reciprocal, that is, it is incompatible with the principle of relativity: an observer starting to move towards the light source CANNOT change the wavelength in the same way. If Majorana had considered the moving observer case, he would have been forced to concude that the ballistic (emission) hypothesis is the only one able to correctly explain the Doppler effect.

DOPPLER EFFECT AGAINST SPECIAL RELATIVITY
Teaching the truth at UCSD:
http://physics.ucsd.edu/students/cou...cs2c/Waves.pdf "Doppler Shift: Moving Observer: Shift in frequency only, wavelength does not change" Since "wavelength does not change", then the speed of light (relative to the observer) does, in accordance with the formula: (frequency) = (speed of light)/(wavelength) Why does the UCSD professor sacrifice Einstein's special relativity so easily? In fact he/she does not. Special relativity is inherent in our civilization and cannot be questioned, let alone abandoned. Of all professors all over the world not one could think of a reason why the admission that the wavelength does not change should trigger further thoughts: http://www.liferesearchuniversal.com...html#seventeen George Orwell: "Crimestop means the faculty of stopping short, as though by instinct, at the threshold of any dangerous thought.
