How does the electron make a photon in an antenna?

And yes, at this on topic, or at least just as on topic as the rest of this thread, since the topic seems to be a sort of general insanity.

Oh no, don't make this thread political. It's already bad enough as it is. :palm:

U say that all existing electrons affect each other.
This raises some interesting questions.
I think that according to the BB theory the light from some stars has not yet reached some other stars – & i think that furthermore BB theory says that the light from some stars will never reach some other stars – hence your statement duznt accord with BB theory.

There is not such thing like light or a photon. Those are just words people invented to describe some known effects.
When you look at the Sun you will see a bright star. That is not because the photons or light flights off the Sun like small balloons towards the Earth and you can see it. It is because the electrons inside the Sun vibrate/move, while they vibrate they affect the electrons inside your chemical bonds in your eyes (there are electron based receptors in your eyes) which then generate electrical pulses/currents your brain evaluates as the "light".
If you see a green LED blinking it is not because some photons or light are flying off the LED, it is because the electrons inside the semiconductor jumps up and down, while their movement fits the electron's constellation within the chemical bonds inside your eyes (and forcing them to follow in sync).
When in an antenna the electrons jump up and down, they affect other electrons in the entire Universe forcing them to jump up and down (a vertical polarization).
When the electrons jump left-right they force other electrons in the entire Universe to jump left-right (a horizontal polarization).
When they are moving in a circle, for example, all electrons in an entire Universe tend to follow their movement (a circular polarization).
Therefore the signal with a polarization mismatch (transmitting antenna vertical, receiving antenna horizontal) produces low signal compared to a matching polarization.
The electrons exist in a space-time thus their movement is pretty complex, therefore you can "see" (detect) the Universe as we understand it today with all its beauties.
When a star flies away your eyes you see it more "red" as the electrons and their field created inside the star follow a complex space-time trajectory, with an end effect of "red-shift" (a Doppler effect basically).
If there was the Sun and an absolutely empty space around it you would not see it shining, as there would be nothing to follow the vibration (interact with) of those electrons inside the Sun..

Don't bother wasting your time with him.
The Doppler effect is interesting, together the way light can exert a physical force on an object. If you take a reflective object, moving away from you and shine a green laser at it. The reflected radiation will be red-shifted, but remember lower frequencies have less energy, so where did the energy go? It gave the object a little push, causing its velocity to increase slightly. The reverse is true for an object travelling towards you. The reflected radiation will be blue shifted and the object will slow down a little, as the extra energy in the blue shifting is robbed from the object's momentum.

Please don't attribute things to me that aren't true. My comment has nothing whatsoever to do with politics - it is about the way a person foes about things. I could equally (but erroneously, of course) had said "Isn't that The Pope's play style" and that wouldn't have made it about religion either. Hey, isn't that Harry's play style - no, that doesn't make it about royalty either.
Get a grip, please.

I like your first point & your last point. Your last point of course raises the topic of aether -- & whether aether or some such thing is needed to accommodate waves or some such – but a discussion of aether & electricity & radio would better need a new thread.

So, according to your theory(s), a green laser light reflecting between 2 stationary mirrors, will quickly end up red.
If the mirrors are say 1 m apart then there will be say 300,000,000 reflexions per second – how many seconds would u say it would take to turn red? – i don’t remember this sort of computation – but it is interesting – i am thinking that an experiment would not support that the laser quickly turns red.
But what about a radio signal reflecting between 2 mirrors – ie em radiation reflecting between 2 mirrors – would the signal looz frequency? – if radio acted similarly to photons then i suppose that according to me the radio signal would not looz frequency.
