Which takes something physically present to do the warping…ok if it can remain spatially fixed but I suspect it will have to dilate on temporal axis to maintain equal and opposite action across frames.

Everyone is making the assumption that a force can only act against another object, because that has always been our experience. This may be the first tangible experience of a force acting against the vacuum itself, rather than another object. If we can warp spacetime, we can also push against it. Does this require that the vacuum be something other than a frictionless superfluid? Eric
