Default Einstein's Constant Speed of Light: Simply Impossible

Albert Einstein Institute: "We will start with a very simple set-up, which you can see in the following animation. On the right-hand side, drawn in green, there is a sender that emits pulses in regular succession. On the left-hand side there is a receiver, drawn in blue. The pulses themselves are drawn in red, and they all travel at the same speed from right to left. Everytime the sender emits a new pulse, a yellow indicator light flashes once. Likewise, a flashing light indicates when a pulse has reached the receiver:

Next, let us look at a slightly different situation, where the source is moving towards the detector. We assume that the motion of the sender does not influence the speed at which the pulses travel, and that the pulses are sent with the same frequency as before. Still, as we can see in the following animation, the motion influences the pulse pattern:

http://www.einstein-online.info/imag...ource_blue.gif

The distance between successive pulses is now smaller than when both sender and receiver were at rest. Consequently, the pulses arrive at the receiver in quicker succession. If we compare the rates at which the indicator lights at the receiver and at the sender are flashing, we find that the indicator light at the receiver is flashing faster. [END OF QUOTATION] http://www..einstein-online.info/spotlights/doppler

Einsteinians assume that

Assumption 1: "the motion of the sender does not influence the speed at which the pulses travel",

but this goes hand in hand with another assumption:

Assumption 2: "The distance between successive pulses is now smaller than when both sender and receiver were at rest."

Assumption 2 is false - the pulses do not bunch up when the source (sender) is moving. If they did, by measuring the (variable) distance between the pulses, an observer associated with the source would know whether he is moving or at rest, which contradicts the principle of relativity.

Since Assumption 2 is false, Assumption 1 is false as well. If the speed of the moving source is v, the speed of the light relative to the receiver is c'=c+v, in violation of Einstein's relativity.

Default Einstein's Constant Speed of Light: Simply Impossible

"In our animation, Zoe turns on the headlights of her space ship. She measures the speed of light from her headlights as c with respect to her. Jasper sees her travelling towards him at (let's say) v. He measures the speed of light from her headlights as c. No, not c+v, but just c. Surely this is counter-intuitive? Maybe even crazy?"
http://newt.phys.unsw.edu.au/einstei...eird_logic.htm

Actually Jasper measures the speed of the light from Zoe's headlights as c'=c+v, not c, in violation of Einstein's relativity. Here is why:

Moving Zoe measures the speed of the light from her headlights as c, the frequency as f, and the wavelength as λ=c/f. If Zoe were at rest (relative to Jasper) and did the same measurements, she would obtain exactly the same c, f and λ. This is required by the principle of relativity. If any of the quantities, e.g. the wavelength, had different values at rest and at motion, the principle of relativity would be obviously violated. By measuring the wavelength of the light she is emitting, Zoe would know whether she is moving or at rest, "without looking at something outside".

So the emitted wavelength is the same at rest and at motion, according to the principle of relativity, and yet Einsteinians fraudulently teach that the wavefronts bunch up (the wavelength gets shorter) in front of a moving light source and spread out (the wavelength gets longer) behind it:

"red shift blue shift" https://www.youtube.com/watch?v=xsVxC_NR64M

Stephen Hawking, "A Brief History of Time", Chapter 3: "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." http://www.fisica.net/relatividade/s...ry_of_time.pdf

The moving source does not emit shorter wavelength - it emits faster light. If the speed of the source is v, the speed of the light relative to the observer is c'=c+v, in violation of Einstein's relativity. The increased frequency established in Doppler measurements is due to the increased speed of the light and represents a straightforward experimental refutation of Einstein's 1905 constant-speed-of-light postulate.

When the observer starts moving towards the light source with speed v, the frequency he measures shifts from

f = c/λ

to

f' = (c+v)/λ = f(1+v/c):

"The Doppler effect - changes in frequencies when sources or observers are in motion - is familiar to anyone who has stood at the roadside and watched (and listened) to the cars go by. It applies to all types of wave, not just sound. [...] Moving Observer. Now suppose the source is fixed but the observer is moving towards the source, with speed v. In time t, ct/λ waves pass a fixed point. A moving point adds another vt/λ. So f'=(c+v)/λ." http://www.hep.man.ac.uk/u/roger/PHY.../lecture18.pdf

"Now let's see what this does to the frequency of the light. We know that even without special relativity, observers moving at different velocities measure different frequencies. (This is the reason the pitch of an ambulance changes as it passes you it doesn't change if you're on the ambulance). This is called the Doppler shift, and for small relative velocity v it is easy to show that the frequency shifts from f to f(1+v/c) (it goes up heading toward you, down away from you). There are relativistic corrections, but these are negligible here." http://docplayer.net/35188128-Modern...ecture-35.html

This means that the speed of the light relative to the observer shifts from

c

to

c' = c+v

in violation of Einstein's relativity:

"Doppler effect - when an observer moves towards a stationary source. ...the velocity of the wave relative to the observer is faster than that when it is still." https://www.youtube.com/watch?v=bg7O4rtlwEE

"Let's say you, the observer, now move toward the source with velocity Vo. You encounter more waves per unit time than you did before. Relative to you, the waves travel at a higher speed: V' = V+Vo. The frequency of the waves you detect is higher, and is given by: f' = V'/λ = (V+Vo)/λ." http://physics.bu.edu/~redner/211-sp...9_doppler.html

"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://a-levelphysicstutor.com/wav-doppler.php
