Honest Roberts, if a theory assumes that light propagates with speed c relative to a special frame, then the selfsame theory automatically assumes that the speed of light is independent of the speed of the light source. So if the Michelson-Morley experiment refutes the first assumption, it automatically refutes the second (that is, the experiment refuted in advance Einstein's 1905 light postulate). FitzGerald and Lorentz saved the false assumption by introducing length contraction and other miracles but then the world had to procrusteanize its sense of rationality and accept that the long train is short (if trapped inside a short tunnel), the 80m long pole is 40m long (if trapped inside a 40m long barn and Einsteinians have forgotten to reopen the doors of the barn "pretty quickly"), the bug is both dead and alive etc: http://www.youtube.com/watch?v=VSRIyDfo_mY&mode=related&search= http://www.math.ucr.edu/home/baez/physics/Relativity/SR/barn_pole.html "These are the props. You own a barn, 40m long, with automatic doors at either end, that can be opened and closed simultaneously by a switch. You also have a pole, 80m long, which of course won't fit in the barn....So, as the pole passes through the barn, there is an instant when it is completely within the barn. At that instant, you close both doors simultaneously, with your switch. Of course, you open them again pretty quickly, but at least momentarily you had the contracted pole shut up in your barn." http://hyperphysics.phy-astr.gsu.edu/Hbase/Relativ/bugrivet.html Pentcho Valev pvalev@yahoo.com
