> one laser remotely generates sound waves that bounce through the body... This is oddly related to what I was just watching. It was a SciShow episode that discussed how phonons which can be generated (come from??) sound waves. The phonons may be affected by gravity in the reverse way than all other matter and may even repel matter. Phonons it seems are not just sound. The MIT website explains "phonon is just a fancy word for a particle of heat." Anyway it seemed somewhat related especially "The resulting mechanical vibrations generate sound waves that travel back up". But I guess the researchers in the article may not have meant the sound waves literally go up. http://news.mit.edu/2010/explained-phonons-0706 http://news.mit.edu/2010/explained-phonons-0706
