Don't see why not as long as you don't try to use it outside of an environment with an atmosphere.

- Robotbeat 9y agoMars is in space. Venus is in space. And, I suppose, the Earth is in space, too. :) But if we're referring to the near-vacuum of space, it's still possible although the forces involved are incredibly small. There is SOME gas/plasma in space, and certain kinds of sound waves with really long wavelengths (called ion acoustic waves) do, indeed, travel through this thin medium. Unlike sound waves traveling in a neutral gas, ion acoustic waves, because they're traveling through a plasma, can also interact electromagnetically. There's a whole bunch of different waves like this that can travel through the plasma in space a lot like sound waves through the air: https://en.wikipedia.org/wiki/Waves_in_plasmas https://en.wikipedia.org/wiki/Waves_in_plasmas ...so I imagine that something like this could work under certain conditions (i.e very large and very low-mass objects).
