First the list of UFO possibilities
a]. hallucinations, natural or induced;
b]. radiation and plasmas [he said "energy packets"];
d]. holograms [he said "projections"];
e]. mirages/ tricks of light;
f]. terrestrial biological forms;
g]. non-terrestrial biological forms;
h]. artificial life forms;
i]. non-animate matter [he said "minerals"];
j]. terrestrial technology;
k]. non-terrestrial technology.
Quite a listing right? And a dead on explanation for a huge segment of what is considered anomalous sky phenomena.... but the Professor goes on to specifically focus on J and K with the photo below:
If the list and the picture above is not enough to stimulate your inquisitive mind (or to read the Professor's article) let me add just a thought or two to the proceedings - the slippery slope of Phenomenology allows for the manifestation of UFOs most likely IMO - at least in the majority of human perceptions/consciousness of the remembered UFO events.
As a phenomenologist my 'able to not be' type of space idea allows for nearly all of the above alphabet soup of UFO possibilities to be 'true' - as the phenomena, even when technological is relentlessly temporal.
