We know "satellite" TV works and exists. We also know the earth is flat. Thus we know it must not work via satellites. I have not done any testing, therefor (at least to me) the method of there operation is unknown.
See, that's my problem. You go on assuming the Earth is Flat and everything must therefore work around that. THEN you yell at us for assuming the Earth is round.
I know satellite TV works because I have one. I spent time setting it up. I know that if I move it only a few degrees, it will lose it's signal. So I point it at the sky and I get a signal. This tells me that it appears the signal is coming from the sky.
Now, there are others nearby and in the whole country who have the same company. Logically theirs works the same way.
Now, because the signal is directional based(ie. you can only get it when pointing the dish at a very specific point), the transmitter can't be an omnidirectional antenna at a high altitude. It also can't be coming from the ground because if it were, that would mean that the light would bend in the same way the signal was, thus allowing me to see the ground station.
SO....
It must be coming from the sky.
So you agree?
