I know that what I am about to suggest will sound a little far-fetched, and possibly even stupid to some [perhaps all] of you. But ever since I became engrossed in the UFO/ET visitation genre as a boy, I have been aware that there is apparently many different types of craft being used as reported by the legions of seemingly respectable witnesses! Apart from the obvious general appearance's reported , ie flat saucer shape,..thicker saucer,..cone ,..oval ,and even up to spheroid shaped , as well as the many other tubular and triangular shaped vehicles etc, that display differing characteristics in both their motion and the sound that emanates from them . And the characteristic's that concern my personal [and quite possibly preposterous] hypothesis usually apply to the saucer and spheroid shaped ones.
....and it is the multitude of quite-convincing testimony of these craft having the distinct appearance of rapid-oscillation !...Even when in an apparent stationary position, time and time again the witness describes the unknown craft as 'Vibrating'.. or agitating in appearance , 'something akin to a taut guitar string that has just been mildly plucked'!
....And in most of this kind of report, the description of the anomalous-craft is accompanied by the witness describing either a distinct or mild 'Humming noise' that is emitted from the object!
I have often ruminated the possibility of these characteristics being not just the simple bi-product of such a craft's engines or propulsion-system...but could these very characteristics actually be the 'Propusion-System' for the craft!...?
Now being "No physicist" , [or not even being a very scientific-sort of chap as many of you have pointed out to me historically! lol]...I cannot really lay down a concise schematic plan of my thought system to present as a 'on-forum peer-review', ...but today I came across this very interesting article and video-example in The Huff Post Science section that is a compatible scientific demonstration that goes a long way to proving that my personal hypothesis might not be so outlandish after all!...?...
...well, what do you guys think...am I nuts or what..?
