Science and Technology news... :: View topic - Waves of sound through the galaxy interfere with each other

Skybuck Flying · Guest

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.

You know, all you really have to do is tune the TV to an unused
channel and then try to decode all the little black and white dots on
the screen. The hard part is already done for you.

Please report back on your findings.....

Well, you got that part right! " I don>t know how radio works." Maybe when
you do learn how it works, how electromagnetic energy is generated and
propogates and that "sound" does NOT travel through empty space, you will
have a greater understanding of what goes on and which side of the bread the
butter is on.

For openers, electromagnetic waves do NOT interfere or interact with each
other as you imply. If they did, you would not be able to see the stars as
individual points or be able to tune a radio.

Maybe you need to dig into the subject a little more before postulating a
grand thory. Good luck.

Due to War Department insistence I do now also subscribe to HBO and
Showtime ;-)

But I only have a set-top box in the Great Room, which is generally
where we always watch movies.

But I distribute the set-top box analog output throughout the house on
channel 4.

Thus my post about "IR over Coax" so I can control the set-top box
from my office ;-)

Might have to in 2009, until then the analog stuff works. It>s $9/mo but
I am pretty sure they would make us pay through the nose to lay the
cable unless we sign up for one of the fancy expensive packages. Basic
Satellite is supposedly only $6 but probably also only if you buy the
stuff at the company store and at company prices.

What irks me is that de-facto they took away the freedom to watch OTA
programming in some areas like ours. Analog works better, plain and simple.

I see we have an ambiguity over the meaning of "interfere"

EM waves in space pass right through each other without interacting.
As someone noted, this is why we can see the stars.

A wave "interferes" with a copy of itself at a detector; this is phase
addition/cancellation.
