HUH? I was under the impression that electricity moved at near the
speed of light too. I'll grant that it's a tad slower than the 'speed
of light in a vacuum' but light traveling through fiber optics is also
slower than 'speed of light in a vacuum'. (IIRC, electomagnetics
traveling through any medium are impeded ever so slightly, which is
why they have to quote the speed 'in a vacuum')
I know it takes electricity one nanosecond to travel 11.something
inches (I think it's .82) through a copper wire. Anyone got good stats
on how long a light year is and is good at converting units of
measure?
