:The basic problem with any variable-c model is that the entire observational record is exactly consistent with constant c. So we're left with two types of model; the one Terry mentions, where c changed in an unobservable way in the distant past, and the one Daniel mentions, where c is different in other parts of the Universe, but these differences manage to leave every observation we make exactly as we would expect if no such change had happened. That essentially leaves us with two different ways of saying "sure, the Universe ''looks'' old, but because of an unobservable, untestable effect, it really isn't."  Which may be ''true'', but it'll never be good science. May as well propose that we all live in the Matrix and be done with it. [[User:Tsumetai|Tsumetai]] 05:30, 19 March 2007 (EDT)

::Oh, theory is out - of course, should have realised earlier. If C is altered, the knock-on effect ould include a shift in emmission spectrum. That would be very easily observed in distant stars. As it isn't observed, that means C must be constantish. Perhaps just a little variation, but not a 1.67-million-times factor. I think that just about kills the 'C is faster elsewhere' idea. - Suricou
