I know a lot of signals (radio, TV, etc..) escape earth all the time... but I was kind of wondering about relatively how much escapes- like can you watch TV while orbitting earth- or is the signal too weak for a standard TV to recieve- or listen to the radio- i don't mean if the signal is intentionally aimed skyward- obviously you can- but basically of existing transmitters- and if everything escapes- then what about signals on the same wavelength or something- like a TV station signal from LA and a TV signal from NY meeting in space or something and interfering with each other... how much does the atmosphere and such weaken signals sent from the surface of earth to space.. (going straight up perpendicular to the surface) and i was wondering, because like you can't get signals from TV stations a few hundred miles away- wouldn't the atmosphere have some sort of signal reducing properties.. something like that. :)
