More on c...(the speed of light c, that is...)
A group of scientists have published some interesting papers relating to the speed of light, relativity's dependance on it for validity, and special cases where it can be prompted to travel faster than expected.
The paper seems to reinforce my view that the special theory of relativity only requires that an "invariant" speed should be measured across all reference frames, which to me is really the most important contribution of the special theory...
I digress that if Einstein did postulate that should anything move faster than this it would move backward in time, I personally think this is a sick point of view and will never prescribe to this opinion, no matter what my respect for the Good Doctor Einstein is...
