Hello,

I don't know how radio works, but I will assume the sound travels in all directions like a wave or an explosion.

Now suppose the universe is fullllll with advanced civilizations, all broadcast on different frequencies in all directions from different locations.

The theory goes as follows:

All these waves of sounds,radio,etc interfere with each other when we reach and observe them from a single location, so to us it looks like noise.

An experimental could verify if this could be happening:

For example a little software program or maybe you hardware people could experiment with it:

Simply encode some information into waves, broadcast them for different places.

Then the idea is to:

Observe these waves from different locations.

Different values will be read at the different locations because of their different positions.

Then maybe find matches in pattern to figure out from which direction the sound come.

Then cancel the waves with each other to get a clear signal or something like.

Maybe sometime when I have some time I try a software simulation of it.

Could be fun.

(I imagine like: a 2d array of colors/pixels, and some waves at some locations, rippling through the array to visualize it.

Then some positions here and there which observe the waves and ofcourse some broadcasters which broadcasts the waves.

The mission is to have the listeners focus on one wave/source and try to decode it.)

Bye,
 Skybuck.

Electromagnetic waves don't interfere with each other. Or maybe you
know more about this stuff than all the radio astronomers and NASA and
SETI people.

You haven't signed up for that introductory physics couse yet, I see.

Multipath ??

Tell me about it. Happened again yesterday. All the digital channels cutting out one after the other, all analog channels just fine. Then in February 2009 ... poof.
