From: Bob Higgins * According to Don Hotson… the ether is composed of epos (shrunken, neutral, electron-positron orbital pairs) that can be polarized. This provides the displaceable element needed in Maxwell's equations…
This could be interpreted as consistent with the proposition that entangled photons couple to the epo field (the vacuum) to provide “traction” of a sort, but un-entangled photons meet little resistance, since they do not displace epos and thus there is no traction, no thrust. I’m a fan of Hotson too but his theory has multiple interpretations. Consequently, this may also mean that all the net thrust seen with the EMdrive occurs inside the cone, not outside. Specifically, entangled photons would polarize the epo field, which may be related to parametric scattering. Jones
