Maybe c has changed a little over billions of years (we don't know yet), but that's not the point. SR nd GR *postulate* that c is constant, nowhere do they contradict themselves on this, and they happen to be accurate to a greater degree than we can currently measure. > http://www.space.com/scienceastronomy/generalscience/faster_than_c_000 > 719.html Highly controversial result, has it been confirmed by anybody else. > With intuition and experience.

Only to a certain level of accuracy, GR does a lot better. You keep stating that SR and GR are nonsensical but you haven't pointed to one inconsistency. I find it rather ironic hearing "Occam's razor" from a geocentric, but it doesn't apply if the more complex theory out-predicts the simpler one. Remember "keep it as simple as possible, but no simpler", I'm sure you know who said that :) Re: occams razor, how do you explain the universe's rate of rotation around the line through the celestial poles gradually slowing down?

You said "this argument was abandoned long ago." thus appealing to others' opinions to back your own.

'See' can be misleading, 'deduce' after taking into account the time it takes the light signals to reach you would be more accurate. But a change of frame of reference does entail distant clocks in the positive direction of the change leaping forward. It is implicit in the Lorentz transformation. It is a result of the relativity of simultaneous events. Surely if you can reason with world lines in Minkowski spacetime then you already know this. > Two: if a third twin is added - a triplet C who stays behind on > earth, then each one will agree that the other 2 are younger! Nope, wrong again. If all we add to your example above is a third stay at home twin then we just have the twin paradox twice. The two that go away age the same as before but age less than the one that stays at home: no contradiction. > One of the demonic results of accepting relativity is the havoc it > plays with logic, a vital component of our God-given reasoning.

If you think truth is determined by morals and ease of learning then you and I have very different ideas about what "truth" means. If you think that just because something is counter-intuitive and difficult it is therefore illogical then you don't know what logic is. >>> I notice that Worzel raised this symmetry issue on BA, and >>> their response was to rattle off the postulates of relativity. >>> Ignoratio elenchi.

No. *You* came up with the reference, *you* back it up. > Speaking of dizzy, if I am on a rotating earth, spinning at least 500 > mph, why don't I feel dizzy, if I use subjective testing as above? Angular velocity is measured in revolutions per unit of time. You spin once per day, that's not very fast. Try turning on the spot over the course of 24 hours, it probably won't make you dizzy either, even if you did it on a very fast moving train. >>> I've never heard of the expansion forces of Mach.

Oh, ok, and everything has an outward centrafugal force from the earth due to it revolving around the earth right? Do you have any maths so I can see how the forces balance for the moon and the geostationary satellites, or should I just take your word for it that it all works out. > As described in a prior post: The satellite - no longer a geostat - > will move to a new value of d for which the new velocity will satisfy > Ag = Af + Ak. This holds for the Moon as well - any satellite not > self-propelled. But surely that implies that d^2(Ag)/d((Ak)^2) = A''(f) which is obviously a monsterous violation of the Mornington Cresent principle ;) Serously though, if you're gonna chuck in maths formulas you should really give the postulates and relevant theoroms of your theory, otherwise it's just meaningless symbol waving.
