Space isn't quite empty. Can it transmit sounds?

short answer: yes.

These waves are of interest to cosmologists, including Mark Whittle of the University of Virginia. Alex Tarnopolsky, made some sound files for him, transposed them up into the audible range. Mark now uses it in his seminars and calls it the "primal scream of the infant universe". You can hear the first million years (transposed upwards by 50 octaves) - along with a nice popular account of these acoustics aspects of cosmology - here: http://www.astro.virginia.edu/~dmw8f/BBA_w...dex_frames.html
