    Questions About Contact in the Movie

    In the movie contact, "vegans" received our omnidirectional radio signal from hitlers olympic games broadcast. until recently, I never asked more questions about the premise that Earth has a 360 degree and 80 light year longem wave front. While this is true I didnt acount for background noise...

    Also, you cannot hide your planets initial em front. So there are 5 possibilities for our non detection 1 their signals haven't reached us yet 2 they're to far away to detect their radio signals. 3 they have since stopped broadcasting in radio before humans started listening 4 they use radio...

    thats answers my question partiality. So signal strength is main culpit. That makes the job of ruling out eti's more challenging radio communications isn't effective for long range communication. And directional lasers are also less effective at long range unless you know where the paths of...

    Questions About Contact in the Movie

    What I am ultimately attempting to establish is if there is a way we can determine that there are no civilizations that have broadcasted in radio within a certain distance from us. I understand that radio begins at 3ghtz and becomes an infrared wave after 300ghts. I would like to know the...

    Thanks unfortunately I previously knewall the information in your reply. I know that 65 light years is relatively short but shift does occur in that distance albeit small. What I am trying to acertain in an understanding of the metrics here. Such as an EM signal will degrade by one bandwith...

    Questions About Contact in the Movie

    Hello I am new here and my question is this: Spatially, what is the distance EM travels through space before redshift alters the wave to the extent that a radio signal becomes a microwave signal? Also when a radio signal containing information redshifts to the microwave band is the...
