A.Meessen does pure science and studies whatever he consider of interest. Regarding UFOs he did inductive research. A priori we don't know if the reported phenomenon is real or not. To test the reality of the phenomenon you have to pose the hypothesis that they exist and see if this leads us to a logical contradiction. Even then, all we could say is we don't know if it's real or not.
As a physicist he studied their propulsion system. There was two main reason to do so. First, we know the physics law and their constrains well. Second, the witness reported the side effects of a totally unknown propulsion system. If witness were making up the data, logical contradictions would be found quickly because most witnesses are not physicists.
For instance, a witness reported seeing a UFO moving at very low altitude above trees. The strange thing was that the top of the trees were attracted by the UFO. Any conventional propulsion system would result in pushing the tree top away. If the UFO was real, how could we explain this observation ? What underlying physic mecanism could produce such effect ? That is how he started studying the UFO phenomenon. As a physicist he focussed in trying to identify a possible propulsion mechanism that could produce the reported effects. The only hypothesis he used was that UFO are real and that they may use the known physics law in a way yet unknnown to us, an original way.
You have to initially suppose the UFO data valid to do this reserach. It can't work by supposing UFO don't exist.
This research led him to two significant results. First the PEMP, a pulsed EM propulsion system [1]. Second, a new type of oscillator using a supraconducting surface that can generate very intense EM fields required for the propulsion [2]. It may not be a coincidence that a supraconducting shell would also protect occupants from the very intense oscillating EM field. Since humans can't produce supraconductive materials at room temperature, there isn't much room left to suppose a human origin of UFOs. The logical and scientific consistency, as well as the sound theory does also point to the reality of the UFO phenomenon. A.Meessen has data that you and scientists don't have to make their opinion, although it is published and in open access.
The idea that UFOs are not real is just a belief supported by a few bogus cases and, I guess, by the fear of ET with far supperior technical skills than us. The idea that UFOs are real is now supported by scientific results. It's just theories that are waiting experimental validation. But at this stage we don't need to make an hypothesis about the reality or not of UFOs. These theories can be tested today in a lab with our technology.
This is pure science, not crack potery. Sorry for your beliefs.
Beside, the validity (or invalidity) of his STQ theory can't be inferred from his work on ufology because they are totally independent. If his theory on STQ is bogus, then say in what it is bogus. Otherwise, you are in the gossip domain, not science domain.
