A very interesting question, especially if you consider effects of gravity on C, and potentially wormholes and string theory's ~17 dimensions.  |
Even the clocks on satellites in orbit have to be design with relativity in mind. Otherwise GPS could go a bit wonky even being off by a minuscule amount of time.
