Glenn's post (whose details I omit here) is very helpful. It
may be worth noting another angle on this. In special relativity (which
has been confirmed by a huge # of observations) c can be seen simply as
a conversion factor between intervals in one direction (timelike) &
others (spacelike): 1 sec = 3 x 10^5 km. (See, e.g., the opening pages
of Wheeler & Taylor's _Spacetime Physics_.) Thus talking about a change
in c would be like talking about a change in the conversion factor
4.2 joules/calorie. (That "mechanical equivalent of heat" used to be
thought of as a fundamental constant too).
