this is an objection that you often bring up, but could it not simply be that, when in what you might call "spaceflight" mode, they wouldnt' be visible to the eye? It could simply be that some byproduct of the propulsion system deflects light, or absorbs it, much in fact as I believe our own Scientists are experimenting with for military purposes here on earth. It needn't be deliberate, or for any Nefarious purpose, it might just be how they work. Maybe they just go too quickly to be spotted.
And that's before we consider questions of dimensional jumps or anything else.
If that is the case we should not be seeing them inside of the atmosphere only. We know that thousands of reports of sighting exist, yet every single one is terrestrial with regards to it's flight path.
Dimensional jumps.

5. Physics A physical property, such as mass, length, time, or a combination thereof, regarded as a fundamental measure or as one of a set of fundamental measures of a physical quantity: Velocity has the dimensions of length divided by time.

Does that equate to another world? Another Universe? That very much remains to be seen. At this point it time, using it as an answer is no more than a guess. We do not have experience with dimensions, we barely have theory. Time travel is just as viable, which negates the need for space travel. So why do the claimed inhabitants, and that is all we have to go on with regards to the ideal, insist that they come from another planet and travel through space? Remember the Hill star map? The Reticulum, Roswell Aliens, all of them are supposedly travelling through space. Dimensionality has been invented to prop up the failing ETH. But is there any reason to think for a second that idea is any more believable than Andrea Rossi? The ideal did not come from testimony, it came from UFOlogy. Do you think that makes it a viable option? I think that lessens it's value as a possibility?
When I think about it, why is dimensional travel on the table? It helps some stories become easier to explain, but has anything rational to date supported this ideal?
From what I understand, we had inflation, and the primary element involved there is hydrogen. What if, and a big what if, this reaction happened slightly differently, I dont now, maybe two different molecules of matter and anti matter collided as opposed to what happened here, and a different element became the most abundant element. Instead if Hydrogen, perhaps some gas we do not know of, or something like helium replaced it. I wonder, surely that would affect the make up of the Universe as we know it. Carbon based life might not even be viable in such conditions. This could create a Universe that could exist right by our own undetected, perhaps even caused by the same "Big Bang".
But that is about as much sense as I have been able to make out from Vallee, like I always say, he a very complex and intelligent person. One that requires a little thought as opposed to the face value stuff.
