Actually, I dont think you can dispute the speed of light. I vaguely recall reading the metre was redefined so we would have an exact measure of the speed of light. Ie, its exactly 299792458 m/s (assuming I remembered that correctly).
Yoiiks! I just hope the speed of light doesn't change, otherwise every measuring tape and ruler in the world will be useless. I use a similar technique in my software testing. I adjust the unit tests to define every output from my code as being correct. I simply redefine my code as being correct. Greg
