Default ONE-WAY SPEED OF LIGHT VARIATION

Collective madness in Divine Albert's world:

http://en.wikipedia.org/wiki/Speed_of_light
"It is only possible to verify experimentally that the two-way speed of light (for example, from a source to a mirror and back again) is frame-independent, because it is impossible to measure the one-way speed of light (for example, from a source to a distant detector) without some convention as to how clocks at the source and at the detector should be synchronized. However, by adopting Einstein synchronization for the clocks, the one-way speed of light becomes equal to the two-way speed of light by definition."

No synchronization is needed. It has been shown countless times that the one-way speed of light is frame-dependent, by demonstrating that the measured frequency is frame-dependent:

Roger Barlow, Professor of Particle Physics: "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/lambda waves pass a fixed point. A moving point adds another vt/lambda. So f'=(c+v)/lambda."

Paul Fendley: "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."

That is, if the frequency measured by the stationary observer is f=c/L (L is the wavelength), the frequency measured by an observer moving towards the light source with speed v is:

f' = f(1+v/c) = (c+v)/L = c'/L

where c'=c+v has a definite physical meaning: it is the (variable) speed of the light waves relative to the moving observer. Special relativity is violated.

parllel universe have diffrent speed of light 128 168 300 299 thats how you find diffrent universe i'm from the planet earth that is the 7th from the sun stuck on one that the planet is 3rd from the sun the speed of light is 128 and 32 dimentions Roger Wilco Misc 1 December 30th 03 10:15 PM
