Cincirob: <font>OK AAF, tell us what you do believeif you can. Yes, now why dont you try to prove it. OK, you cant tell me what you believeonly what you dont believe. In other words, you have nothing to offer. Again, you have no answer for my question. </font>
AAF: Let's see! You're familiar with the simple experiment of Michelson & Morley. Do you really think they could have used starlight in their experiment? They couldn't have used it, because their experimental beam must be intense and monochromatic to give observed results. As I pointed out many times, experiments performed on the basis of the Ether theory, including those of Michelson & Morley & Arago & Airy, were designed for testing and searching only for (c+v & c-v) of moving observers. Whenever there was a relative speed between (source & observer), the results of those experiments were positive & successful (e.g. the Fizeau experiment & the Michelson-Gale experiment).
By contrast, whenever the given speed was the common speed of (source of light & measuring observer), the experimental results were null & unsuccessful (e.g. the Arago experiment & the Michelson-Morley experiment). The reason, behind the spectacular failure of the latter experiments, is that the Ether theory does not recognize the (c+v & c-v) of sources of light. And hence, experiments based on the Ether theory, inevitably fail, whenever (c+v & c-v) of the light source are present & (v) is the common speed of both the source of light & the measuring observer. And that is because, in the special case of common (v) for the source and the observer, the (c+v & c-v) of the source and the (c+v & c-v) of the observer cancel each other out according to the rules of relative motion. Now, your Albert concluded from that failure that light must have the same speed for all observers and in all inertial frames of reference at all times regardless of the actual value of the speed (v).
Let's see where your Einstein got it right and where he got it wrong:
 Einstein got it right in the special case of (source & observer) moving with the same speed in the same direction. In this particular case, light, indeed, always travels at a constant speed of (c) as measured by the same observer, regardless of the numerical value of (v).
 Einstein got it wrong in the special case of (moving source & observer at rest).
 Einstein got it wrong in the special case of (moving observer & source at rest).
 Einstein, finally, got it wrong in every case of (moving source & moving observer), except in the special case, where both the (source & observer) are moving with the same speed in the same direction (i.e. Case #1 above).
Therefore, your Einstein's theory of Relativity is 25% right and 75% wrong.
