Do you really think that SR ignores its postulate that the speed of light is c according to all inertial observers?
Do you really think that scientists are so stupid that they do not test SR - including the speed of light from moving sources?
What is the experimental basis of Special Relativity? 3.3 Tests of Light Speed from Moving Sources
You are wrong, wogoga. To derive time dilation you need to use all of SR. That post was silly - it starts with the relativistic Doppler formula to arrive at relativistic time dilation.I only want to show that also from the alternative premise "speed of light is c only for observers in a privileged frame assumed at rest" (non-mutual) time-dilation can be derived.
That is a bit hypocritical, wogoga. You acknowledge that SR is a "efficient and useful theory " which is why it is not flawed! And then have the fantasy that SR is fundamentally flawed. While using SR in the post starting with the relativistic Doppler formula!In general I try to understand why Special Relativity is such an efficient and useful theory despite being fundamentally flawed.
So you know that you can show that any experiment inPlease choose the experiment which according to you most convincingly contradicts what I have written. Then I can demonstrate that the experiment is either irrelevant or simply wrong.
Right here as a matter of fact: http://www.internationalskeptics.com/forums/showthread.php?p=10826567#post10826567
In this thread, we have a poster who presents all maths and no logic
Over in Waterbreather's thread, we have all logic and no maths...
Both are about relativity... hmmmm
What would happen if we combined the threads?
- a big kaboom?
- no logic and no maths, thereby removing the thread from existence
- illogical mathematics, that manages to prove that the speed of light is potato
- a breakthrough in human thinking, from which we wake up and go "...but it was only a dream."
- string, pumpkins, and those tiny cocktail umbrellas describing eccentric elliptical orbits around all the bukkits ever taken from lolrusi
jeez, guys - keep up!![]()
Please choose the experiment which according to you most convincingly contradicts what I have written. Then I can demonstrate that the experiment is either irrelevant or simply wrong.
Please show how "Operation of FLASH, a free-electron laser" is wrong.
This experiment is irrelevant, as my arguments have nothing to do with any form of ballistic theory of light.
Quote from the summary of the experiment:
"... relativistic electron beam … generates the X-rays … speed of light emitted from the moving electrons is c+kv … observed … upper limit on k of 2.5×10−7…"
In the same way as Einstein, I assume that k is exactly zero. Nevertheless, I assume that Einstein has been fooled into believing that this is caused by the Lorentz transformation. In reality however, this is caused by ether dragging according to the inverse-square-distance law.
The refutations of this ether-drag hypothesis are as wrong as Einstein's "resolution" of the twin-paradox.

Wrong, wogoga.This experiment is irrelevant, a...
Starting with Paul Langevin in 1911, there have been various explanations of this paradox. These explanations "can be grouped into those that focus on the effect of different standards of simultaneity in different frames, and those that designate the acceleration [experienced by the travelling twin] as the main reason...".[2] Max von Laue argued in 1913 that since the traveling twin must be in two separate inertial frames, one on the way out and another on the way back, this frame switch is the reason for the aging difference, not the acceleration per se.[3] Explanations put forth by Albert Einstein and Max Born invoked gravitational time dilation to explain the aging as a direct effect of acceleration.[4]
Oh really? So how does your interpretation of aether dragging reconcile the failure to accommodate stellar aberration, whilst relativity does?
Thus we have to conclude: During reversal of direction, with respect to the travelling twin, clock-cycles corresponding to 199.98 years must be accomplished in the light-clock.
All aberration-based arguments against dragged ether start with the premise that light is a continuous phenomenon analogous to the propagation of sound, where propagation direction is orthogonal to the wave-front.
If the photon hypothesis already had been generally accepted then such a strange hypothesis as "length contraction" probably would not have been taken seriously in the first place. The alternative hypothesis "wave-fronts breaking-apart" is simpler and much less mind-boggling.
A photon emitted by the sun simply follows the direction of inertial movement when it adapts its speed more and more to the average velocity of the particles constituting the mass of the Earth. This complicates a little bit further the already complicated question of coherence-of-light, but it fully explains the fact that sun-light is "aberrated".
Ether dragging according to the inverse-distance-square law means that every particle in the universe drags the ether according to its mass (in the same way as every particle generates gravitational attraction). In order to calculate the movement of the ether at a given point, we simply use weighted averages of these effects (if interested see). Gravitational time dilation due to lost gravitational potential, and light bending due to gravitation show that masses are capable of influencing photon behavior.

To derive time dilation you need to use all of SR. That post was silly - it starts with the relativistic Doppler formula to arrive at relativistic time dilation.
As long as you do not understand the simple reasoning shown in post #33, you cannot judge #43.
And what do you consider wrong with my treatment of Langevin's twin paradox (Lorentz-factor 100; one-way travel distance of 100 LY)? Let us use two light-clocks (with light-pulse moving orthogonally to direction of relative movement) instead of twins: one clock at rest (R-clock) on Earth and the other clock (T-clock) travelling at v = 0.99995c.
Which point do consider invalid? Or do you think that the light-clock principle itself is not consistent with SR, or that SR-simultaneity cannot be applied to the inertial motion of the travelling clock?
- Distance of 100 light-year is reduced for T-clock to 1 LY during both outward and return journey.
- Both trips need each 100 LY / 0.99995c = 100.005 year, resp. 1 LY / 0.99995c = 1.00005 y.
- During 1.00005 y of one way, pulse in T-clock moves 1.00005 LY relative to T-clock.
- During 1.00005 y of one way, pulse in R-clock moves 1.00005 LY relative to T-clock.
- This 1.00005 LY path of R-clock pulse relative to T-clock is only a 0.0100005 LY path relative to R-clock.
- During 1.00005 y of inertial motion, 0.01 y pass in R-clock (corresponding to the 0.01 LY).
- During two times 1.00005 y of inertial motion, 0.02 y pass in R-clock.
- When both clocks meet again, 200.01 y (corresponding to light-pulse path of 200.01 LY) have passed in R-clock.
- During direction-change, pulse in R-clock moves 200.01 LY – 0.02 LY = 199.99 LY.
The contradiction is obvious:
Cheers, Wolfgang
- For the travelling clock, time of the clock at rest is running slower by factor 100 during both inertial movements.
- For the travelling clock, time of the clock at rest runs on average faster by factor 100 over the whole round trip.
- Yet running faster by factor 100 is the opposite of running slower by factor 100!
- The confusion between "slower by 100" and "slower by 0.01" as the opposite of "faster by 100" has helped SR to prosper.
I consider it wrong because it is relativity gibberish, wogoga. Making it more complex relativity gibberish does not make it better....snipped insults...
And what do you consider wrong with my treatment of Langevin's twin paradox (Lorentz-factor 100; one-way travel distance of 100 LY)?
You do neither. All you do is repeat Langevin's original twin paradox as if no one here can read.Starting with Paul Langevin in 1911, there have been various explanations of this paradox. These explanations "can be grouped into those that focus on the effect of different standards of simultaneity in different frames, and those that designate the acceleration [experienced by the travelling twin] as the main reason...".[2] Max von Laue argued in 1913 that since the traveling twin must be in two separate inertial frames, one on the way out and another on the way back, this frame switch is the reason for the aging difference, not the acceleration per se.[3] Explanations put forth by Albert Einstein and Max Born invoked gravitational time dilation to explain the aging as a direct effect of acceleration.[4]
In 1911, Paul Langevin gave a "striking example" by describing the story of a traveler making a trip at a Lorentz factor of γ = 100 (99.995% the speed of light). The traveler remains in a projectile for one year of his time, and then reverses direction. Upon return, the traveler will find that he has aged two years, while 200 years have passed on Earth. During the trip, both the traveler and Earth keep sending signals to each other at a constant rate, which places Langevin's story among the Doppler shift versions of the twin paradox. The relativistic effects upon the signal rates are used to account for the different aging rates. The asymmetry that occurred because only the traveler underwent acceleration, is used to explain why there is any difference at all, because "any change of velocity, or any acceleration has an absolute meaning".[A 6]
