I've suggested (& published in 21 journal papers) a new theory called quantised inertia (or MiHsC) that assumes that inertia is caused by horizons damping quantum fields. It predicts galaxy rotation & lab thrusts without any dark stuff or adjustment. My University webpage is here, I've written a book called Physics from the Edge and I'm on twitter as @memcculloch. Most of my content is at patreon now: here

MiHsC vs EmDrive: paper link

The EmDrive is extremely interesting: a truncated metal cone that, when resonating with microwaves, moves slightly towards its narrow end. This anomaly was first observed by Shawyer (2008) and later reproduced by Juan et al. (2012) in China, and recently by NASA's Brady et al. (2014). The Emdrive is still uncertain because it hasn't been tested in a vacuum yet (now it has), so it is probably wise to stay well away for now. Nevertheless, I got interested because I'm always looking for lab tests of MiHsC, and I've found that MiHsC can predict it quite well if you assume that photons have inertial mass and the metal cavity forms an information horizon. I've just published my findings in the open access journal 'Progress in Physics', here. Comments welcome.

The guys at the NASA site are curious about your paper. One asked about an expanded version of formula 6.

Thanks. I'm working on it..
