A scientist going by the name Salvatore Cezar Pais, employed by the U.S. navy, was recently granted the following eyebrow-raising patents:

-High frequency gravitational wave generator (10322827)

-Piezoelectricity-induced Room Temperature Superconductor (20190058105)

-Craft using an inertial mass reduction device (10144532)


The author seems to be legit. Here is a list of his publications: link

He also patented what looks like an "emDrive," again for the US government: link

This article has more details

The claims are literally out of this world. Frictionless aircraft that move hyper fast in water/air/space, generating gravitational waves, inertial mass reduction device, etc. Is this a joke? can anyone go through some of these patents, filed by no other than the U.S. Navy, and shed some light into these claims?

The articles go a little into conspiracy theory domain and connect the patents to strange sightings by US pilots: link

Its serious enough that even the president was briefed: source

I am personally skeptic but I can't deny that the sightings seem real. I just wonder why they would let the world know about breakthrough technology instead of keeping it secret. Are the bluffing? First step for me is asking someone knowledgeable.

  • $\begingroup$ I dont know about these csses, but once i talked to the cto of a reputable company. Their patent strategie was to patent also a lot of non working things, so competition cannot tell what they are actually using in production. I am not saying this is the case here. $\endgroup$ – lalala Aug 10 at 11:01
  • $\begingroup$ After a quick reading of the "gravitational wave generator" abstract, I can say that it has absolutely nothing to do with the concept of gravitational waves used in General Relativity. $\endgroup$ – Feel My Black Hole Aug 10 at 11:41

These are heavy claims, hence they require similarly weighty evidence. Regarding their plausibility, I would offer at least two points:

  1. Patents are not, in any way, shape, or form, much of an indicator that a device actually performs as advertised. Many patents are issued all the time for unworkable devices - all it takes to get one is simply that the device be intended to provide the described functionality and not obviously unable to do so. Keep in mind the patent offices are not, at all, staffed by scientific experts who can make a detailed study of any and everything that comes before them. While Einstein was a patent clerk, the converse is hardly ever true.

  2. The EmDrive has been pretty well-refuted as of 2018, thanks to a team based in Dresden, Germany, who tested it by measuring the "thrust" it appeared to generate when aiming it at an unusual angle, and the supposed "thrust" did not behave as though it were genuine thrust. The references to "quantum vacuum plasma" appear to be a reference to Harold "Sonny" White's work on this engine, with the idea growing from there; hence with its debunking I think it's safe to say this stuff is non-credible as well by counter-implication.

So yeah, it's just another set of extraordinary claims with no extraordinary evidence. Sadly, there still does not appear to be any easy way to manipulate gravitational forces that does not involve astronomical-scale engineering.


There are several possibilities. (This is not an exhaustive list.)

  1. These technologies were developed some time during the Ordovician epoch by a race of giant sentient cephalopods, and survived the extinction of their creators in the catacombs of the lost city of Irem, where they were discovered by American petrochemical engineers working for Saudi Aramco. They were swiftly transferred to Area 51 in North America, where they have been the subject of a generation-long exercise in reverse engineering, now approaching fruition under the leadership of Dr Pais.

  2. It's a psyop meant to get the Chinese working on inherently useless technologies, just as 1980s reports of experiments in remote viewing conducted aboard American submarines may have been a psyop meant to make the Russians waste their efforts on psychical research. Or maybe there's a psyop that the Chinese are running, and this is the Americans falling for it.

  3. Dr Pais has a personal theory of physics according to which all these things are possible, and a supervisor who says "the hell with what the theorists say, if these things are possible, we can't afford to miss out", and who champions Pais's research within the Navy bureaucracy.

I apologize for not attempting to judge the plausibility of these devices from the standpoint of known physics, perhaps someone else (or someone at Skeptics SE) will do that for you.

  • $\begingroup$ I suppose a more serious answer would go through each of the claimed physical effects, explaining how each rests on some kind of miracle happening, and the kind of handwaving which would allow an eternal optimist to say "this is how we will make the miracle happen"... In a comment at nextbigfuture.com/2019/02/… , some papers by Pais are cited, which I have not yet examined. $\endgroup$ – Mitchell Porter Aug 10 at 11:42
  • $\begingroup$ I vote for 2 as the most likely. I read the patent and reads like rubbish $\endgroup$ – lurscher Aug 10 at 14:14
  • $\begingroup$ @lurscher : The most reasonable answer is it's just a kooky guy who thinks he has cool stuff, probably doesn't understand how to take measurements as well as he should, and puts patents under the mistaken impression they'll give him fame and fortune or perhaps, at least, that they'll let him see within his lifetime interstellar voyages ... $\endgroup$ – The_Sympathizer Aug 10 at 22:31

    $\begingroup$ @The_Sympathizer Please read the article at thedrive.com. The patent application for the undersea craft was initially rejected by the patent office, until Navy lawyers and a Navy executive argued on its behalf. Pais is not acting alone. $\endgroup$ – Mitchell Porter Aug 10 at 23:49
