all our current laws of physics have just been trashed if we can do that.

Yanno, Cecil is like that, just when you think you have a handle on
things--HE chucks a monkey wrench in it!

If you are traveling away from me, at the speed of light, and you are
transmitting to me--wouldn't you be "stretching" that rf wave "flat."
In effect, what I see is a DC signal (well, actually I don't see
anything.) Owing to the doppler effect?

Now, if you exceed that speed of light, what happens to that rf you are
emitting? I'll have to think on that one a bit ...

Warmest regards,
