Mary wears a blue dress. Since Sally wears a blue dress, we must conclude that Mary is really Sally, and Mary doesn't exist. Hmm... that's logical syllogism for you. :^} <...>

Enjoy your ignorance.

Well, if you want to claim that something that is not detectable and has absolutely no effects on ordinary matter or energy is there, you are free to say so of course, just as I am free to claim the room I am in is full of invisible pink elephants that nobody can see, hear or otherwise detect. But we know what Occam's Razor has to say about things like that. Einstein, too, when he stated his work would not involve the lumiferous aether. >>> The relativevelocity of an object wrt light is c-/+V_a >> >> Nope, all observers always measure the speed of light in a vacuum as c. >> This is a fundamental basis of physics, and has been measured to high >> accuracy for years. >Hey idiot the one-way speed of light never been measured.

The wavelength of a frequency shifted photon changes in inverse proportion to its frequency, so its speed (frequency * wavelength) is *still* c. For example, a photon with a 600 GHz frequency when emitted by a star whose redshift from Earth is so large that it has a 300 GHz frequency upon arrival on Earth, will have a wavelength of about 0.5 mm upon emission. Upon arrival on earth it will have a wavelength of about 1.0 mm. Guess what. At both the source and the Earth, its speed is the frequency * wavelength, and in both cases it's c! So once again, since the speed of the unshifted photon is c, and the speed of the frequency shifted photon is c, the difference is always 0, so what you call "absolute motion" is always 0. Since the V_a term is always zero, your "absolute motion" concept, which must always be zero, is a pretty useless concept. >> In fact the reason why the meter has been redefined in terms of c is >> because of the fact that c is a fundamental constant of the universe, like >> h, or G, or alpha or several others. >No the speed of light is defined to be c to fix SR. Nope, it was *always* measured to be c, before the redefinition. The redefinition makes perfect sense, why make the definition of a fundamental dimension of physics (length) in terms of some physical property or other, when you can define it *more accurately* in terms of another fundamental dimension of physics (time) and a universal constant (speed of light)?

A simply measures B's clock as running slow as far as A's clock is concerned. In A's frame, A's clock is just fine. Similarly, B simply measures A's clock as running slow as far as B's clock is concerned. In B's frame, B's clock is just fine. |
