Default Antennas led astray

No oproblem with 0 frequency or 0 energy being released from a particle
traveling at the speed of light relative to that partcle.Negative frequency?
all our current laws of physics have just been trashed if we can do that.



Jimmie:

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,
JS

Yanno, an analogy has stuck me.

If I know what speed waves travel in water and I stand on the shore of a
lake and have a boat, making waves, travel away from me, I should be
able to see the first case. Then, when the boat exceeds that speed, I
should also be able to see the results ...

Trouble right now is, I don't know the speed of waves in water and I
don't have a boat. To tell you the truth, can't even remember what the
waves looked like when I have had past opportunities ...

Regards,
JS

Assume you remember WWII. An Atlantic City newscaster
once reported that a Marine had been sucked under the
boardwalk by a big Wave.

Consider that the relative velocity between you two
could exceed the speed of light without either one
of you actually exceeding the speed of light referenced
to a point midway between you, which is thought to be
impossible except, of course, at warp 1.1 on Star Trek.
Tom Paris actually managed 10^10 times the speed of
light but it had severe side-effects. (He was forced
to mate with Captain Janeway) :-(.

Cecil:

Exactly, we COULD exceed the speed of light and greater, in relationship
to each other! And, then the behavior of the rf, transmitted between
us, could be observed at greater than light speeds.

NOW. Don't knock Capt. Janeway--I kinda like strong women
