Neural messages are generally transmitted about 20010 million times slower than an electrical message light, which is a few hundred travels about a million times slowerfaster than sound, which in turn is a few hundred times slower than light. There is no possible wayIt is extremely unlikely for a neural message to travel faster than the speed of light.
This makes more sense to me. From what I remember, our reaction time is about 0.1 seconds, and is at best 0.01 seconds (test yourself by tapping as quickly as you can on a stopwatch). This means nerve impulses travel at most 10 to 100 m/s. The speed of light is ~3*10^8 m/s. Most electrical currents travel at a similar speed -- sometimes 10 to 100 times slower. So "light" and "electrical message" could pretty much be used interchangeably in the above quote, but it seems more direct just to make the comparison with light, unless you want to write something a little more long-winded about nerve impulses. The speed of sound in air is about 350 m/s.
Of course, there are many problems with this theory, but perhaps most notably -- pretty much your entire body would have to be travelling at some speed relative to the alarm clock, not just some nerve impulse.
