If your traveling at the speed of light, and you turn your headlights on, does anything happen?
-Steven Wright-

Did Mr Wright not take physics? Special relativity answers this question:

1. You probably can't travel at the speed of light without using infinite energy to get there. Suppose you are traveling 1 mph less than the speed of light.
2. An outside observer sees the beam of light moving away from you at 1 mph (relative to your car) but 186,282 mi/sec relative to himself
3. You see the beam moving away from at the usual speed of light, 186,282 mi/sec

Wrapping your head around that result leads to all sorts of odd conclusions, like the one that says the fixed observer would see the clock in my moving car running much, much slower than his.
