The other night I was laying in bed thinking about how we might contact another civilization or at least listen in on one. I then began thinking about the acoustics of space- which I know nothing about. I went to school for audio production so am familiar with acoustics in general but am curious to how they work in space with different types of waves. Does gravity have an effect on waves as they travel through space? If so would it be possible to anticipate orbits/positions of objects in space in order to bend waves in a particular direction? I know that with acoustics here on earth design is everything, if a room is poorly designed there will be poor sound quality and in some instances no sound at all even with very loud music playing-- does this work the same way in space? Is it possible that there are many signals floating around that we just don't see/hear because of where we're positioned? I would assume that the acoustics of a solar system, galactic plane, and galaxy would all work quite differently... can anyone elaborate on this thought? What do you think the best way to effectively communicate with another civilization would be? I would think it best to daisy chain satellites from earth to the edge of our solar system and beyond if possible to ensure we're picking up everything there is. Please give me some feedback, all science and opinion is welcome!
