Antenna @ speed of light...
 

I pictured this, I am in a spacecraft doing the speed of light, I key
the xmitter and begin a long winded rant, the antenna is monopole.

Now the signal leaving the rear of the antenna appears to be leaving it
at 2X the speed of light (allowing for the VF of space-ether), however,
the signal off the very front, at least the width of the antenna
conductor itself, cannot leave (since I am traveling at the speed of
light the signal appears to just stay on the surface of the
conductor)--what will happen?

Warmest regards,

Ok, no takers so far, and since I am having trouble sleeping...

I remount the xmitter in the space craft...
Now the rear of the xmitter is facing the rear of the spacecraft--and
the antenna just happens to be back there at the rear of the spacecraft
too... we continue at the speed of light...

But now, the signal is shot through the coax at 2x times the speed of
light (due to its speed through the coax, combined with the fact that
the coax is traveling at the speed of light and the signal travels in an
opposite direction through that coax)... the signal now strikes that
antenna at 2x the speed of light and is able to leave the front of the
antenna at 1X the speed of light! ...or, does it?

But, suddenly I notice a problem at the front of the spacecraft and, it
is dark up there... no problem, I grab my trusty flashlight, point it at
the front of the spacecraft and turn it on... but, big problem, the
front of the spacecraft remains dark... I move the flashlight and notice
a bunch of light photons hanging in the air right where I had been
holding the flashlight... unable to overtake the speed of light I am
traveling at!!! Indeed, it is getting pretty darn bight inside this
spacecraft now, as no forward light is able to travel forward and be
reflected or absorbed...

My co-pilot suddenly says, "That is impossible! The flashlight is
traveling at the speed of light, any light it gives off has to be
traveling at 2X the speed of light and can go forward--those photons
cannot possibly be there hanging in midair!"

To which, I respond, "Nothing can go faster than the speed of light,
fool!" grin

(I just threw in the "fool" for effect... the co-pilot knew I was
kidding)

.... maybe I can sleep now...

Warmest regards,
John

you might want to try this on sci.physics.relativity, they like pointing out
all the errors in your logic when you start with impossible conditions.

The Doppler effect doesn't change the speed of light, only
the frequency. All EM waves appear to all observers to
travel at the speed of light.

(allowing for the VF of space-ether), however,

It doesn't appear that way to you. For you, time has stopped
but you don't know it. You also possess infinite mass and occupy
zero volume but you don't know it.

(since I am traveling at the speed of
light the signal appears to just stay on the surface of the
conductor)--what will happen?

It would make more sense to assume that you are traveling at
1/2 the speed of light and see what happens. Future humans
may be able to do just that. Assume you have a twin brother
back on earth QSOing with you. He's transmitting in a ham
band. What frequency do you hear him on?

Since you are traveling at the speed of light, everything,
including your brain, stops working.

And here I was, wondering what the problem could possibly be.

W4ZCB

Same thing that will happen when you point your flashlight forward at V=C,
the light falls on the floor :)

In John's case, 30 MPH seems to do the trick...

Actually, standing on the earth we are already moving at over 1,000 mph.
If you point a flashlight in the direction of rotation--it has the
potential of +1,000 mph than when you turn around and point it west.

Also, the universe is expanding, and that is pushing us on at a good
clip. Funny you don't see this being taken into account anywhere except
on space launches... but I have noticed what looks like a speedier
launch in one direction of my monopole, as compared to the other...

.... most notably, when my ant is at an angle 90 degrees to the combined
directions of both the rotation of the earth and the expanding universe
direction... grin
