Actually t'= t*sqrt(1-v^2/c^2). There's nothing about acceleration here. Accelerating frames are matter of special relativity. Also twin paradox can be solved in special relativity only (edit: sorry not special, but general relativity in both cases).

Ah yes, you are right. I was thinking about the wrong thing. Let me try again: the author's contention that the relativity of motion (which is true) makes time dilation logically suspect is wrong because of the symmetry of time dilation while the twin paradox effect is actually an example of non-symmetry.

Beleive me, that's very relavent.

I was hoping this was a thread about Fitzpatrick's War.
