A vacuum cannot allow ANYTHING to move within it, which includes your satellites or signals. Deal with that because it's the reality.
that doesn't sound right.
That sounds the opposite of right.
I mean the air is closer to a vacuum than a brick wall is yet I can run through the air easier than I can run through a brick wall.
Seems to me a vacuum would be even easier to move through than the air.
Besides which the composition of their air around the TV transmitter is only relevant once we've ascertained it's position, which is damn high up.
Of course it seems easier to run through a vacuum, because your mind has been saturated in so much bull crap that you cannot comprehend what a vacuum actually is.
You just think of thinner air or less matter and that's not what a vacuum really is.
You could not run inside of a N.A.S.A evacuation chamber. WHY?
Because your body would be quickly taken apart, meaning all of your heavier elements would be expanded to fill what was being evacuated, so you aren't running anywhere easier or at all.
Your body is designed to live where you are, under 14.7 psi of pressure. Go higher and you suffer for it. Go lower, as in water and you suffer for it.
As far as signals go, sound, light or signals as we know them work better for what WE perceive, in our atmosphere, in our pressure.
Think of your signal as throwing a ball into the air and it falling back down back into your hand. Depending on the strength of throw, depends on the distance you can send that ball (signal)...
If you want someone to catch it over a distance, then you angle your throw to gain the bigger distance, or you bounce it up and down, or basically you play a game of relay racing with it.
This is all that's happening with signals, only I'm explaining it in a crude and simplified way.
Whales and other species communicate this way, by frequency and vibration, because every molecule on this earth is attached...and every species can detect their own vibrations through it, because it's simply a wave not unlike holding a length of rope and whipping it to see the ripple run along it, except only faster.
Time and distance of any sound is dependent on the severity of it, just as light to your eye is dependent on the severity of it as to how much you see of it in distance from which the friction/vibration/sound that created it, may or may not be strong enough to merit a vibration of your ear drum from your hammer in your ear for your brain to pick up the sound, only the light.
You are walking about under magnetic conditions, mostly so small that you as a human would never guess it.
