[dying to know what the consensus ended up being on this radical theory (pub 23 Jul 2018). guess I'l do some hunting; tips appreciated]
trio of #ColumbiaUni physicists is making waves with a new theory about #phonons—they suggest they might have negative mass, and because of that, have negative gravity. Angelo Esposito, Rafael Krichevsky and Alberto Nicolis have written a paper to support their theory, including the math, and uploaded it to the xrXiv preprint server.
Researchers suggest phonons may have mass and perhaps negative gravity
