- Oh, come on. That's just a dodge. The speed of light is independent
- of the units you choose to measure it in. If I take two light beams,
- and you measure the speed of light in cm/sec and I measure the
- speed of light in droobles/flimbat, the light from the two beams will
- still travel at the same speed. Why *that* speed?
