Dear Rick,

Yes, I know that talking about this matter one enters into the lion turf. I am following all the fuss around this matter in US. My take is that, as customary, Pentagon has a new toy and is trying to mislead other contenders. When this will come out in full only they possibly know.

Thanks for your feedback, I will go through your papers and try to find a lead (I am a bit rosted, I have to say, so it will take some time, but motivated).

I was looking at this site https://www.uaptheory.com/ the other day. It looks at IR sensor data in Chile and at the US Navy “leak”. The Maldacena argument at the beginning seemed a bit like a “one way street”, but the picture analysis / observational part looks quite pertinent (i.e. lensing effect around the objects).

Since the US Navy confirmation, we have some reason to believe that those videos are not fake. Question is, if the observed effects are sensor or video compression artifacts, but having some experience working with mil. EO/IR sensors, I do not think so.

It seems a rather interesting paper. Anyway, it works in five dimensions and this would require an infinite tower of scalar excitations that have not been seen so far.

On the other side, it is possible that, as it also happens for the Higgs field, there are scalar fields permeating space-time (e.g. quintessence) that could play a role. This kind of fields has the property to have negative energy density but one could not escape QFT. E.g., see my paper https://arxiv.org/abs/1409.3775.

In classical GRT, warping factors can arise quite naturally. E.g., see https://www.mdpi.com/2624-8174/2/4/39. This could be easily put to a test.

I am trying to figure out if the new term in eq. 25 of Li-Xin’s “Theory of Electromagnetic and Gravitational Interactions” (arXiv:1511.01260v2) could lead to negative energy density under certain (EM) conditions.

This would be quite elegant, since it would not require to “twist around” with QFT and produce a result from purely classical QED / GRT considerations (hope).

Any thoughts?
