A while back I read an interesting but possibly also batshit crazy article that proposed an explanation possibly involving something like quantization of inertia, and/or generation of extremely long-wavelength photons, wavelengths on the order of the size of the universe. Does anyone know what I'm talking about? IIRC it was based on some theoretical work that was done before EmDrive was a thing, and it seemed less hand-wavey to me than simply "conservation of momentum is wrong" or "we're using the quantum vacuum as a tractive medium which is supposed to be impossible but whatever" explanations. I'm not saying this explanation is right (or wrong, or that the thrust observed in these experiments is or isn't caused by "new physics"); I'm just curious whether anyone knows what I'm talking about and can provide some more context. edit, found it: https://www.technologyreview.com/s/601299/the-curious-link-between-the-fly-by-anomaly-and-the-impossible-emdrive-thruster/ https://www.technologyreview.com/s/601299/the-curious-link-b... Any thoughts?
