Vacuums
Vacuum's don't fluctuate since a true vacuum would contain no more energy than Zero Point, Fluctuations in frequency involve the ebbing and flowing of atoms within a volume to "transverse" the oscillation communique.
Namely a moving particle has to collide with another particles system (e.g. an atom) to convey motion in the form of oscillation.
An atom does have a natural Oscillation level, and it has been proven that if the right harmonics are met it can cause an increase in radiological breakdown. (there is even theory to suggest that there would be a harmonic to correct radioactive breakdown too) such usage of oscillation can be found in Radiotherapy when certain chemical chains are targetted. (I remember once coming across a chart of different frequencies for Viruses, which of course could have been used for Gene Therapy albeit it would be *Extremely* painful)
Steady State Theory
If you believe the universe is "refueling itself by itself" then obviously the theory I suggest you look at that covers one of the many universe theories is the
Steady State Theory, which suggests that the universe is "flat" mathematically. (Flat as if you were to identify the universes mass content from it's beginning and draw a line with it's exponential growth, the line would move near enough diagonally in regards to the change of atomic state.)

Gods vs. Aliens
I suggest that people that are religious in any sense of the word, refrain from stating that any "God" is alien in origin. Firstly if aliens do turn out to be very much like my identification of individuals doing illegal clandestine projects that are very human, calling them a "God" is only going to cause them to continue to think they can play at being "God". (This tends to go hand in hand with the criminal "genus" [Genus, not Genius and usually meglomaniac] that believes they are above all laws and if they were taken to court over their misuse of such equipment they might attempt a "religious clause" based upon their "Following" which will be made up of the mislead and decieved)
Also when looking at the aspects of Theology, wasn't "Man made in the image of God", if that was the supposed case, the a "God" wouldn't be alien either.
Self imposed heirarchy systems
based upon the topic of how supposed "higher beings" would make use the "lower ones" by how they see fit, I see as a definition of complaisantsy or self imposed importance on the perpertrators of the "alien sharade".
"Brain Washing" or "Mind control" when a success would utilise such complaisantsy to their advantage, namely if you were inclined to think you were beneath someone they would "Use you" and take advantage, I think this a very creul demeaning method of doing business and most of the time the self-imposed "Higher Beings" really do need to be brought into alignment with the real universe as appose to their secretive society.
I know that man's history in not so distant years imposed slavery slavery of one race over another, and such bigots as the Nazi regime still imply their "higher being" over any creed that doesn't meet their understanding and thus implied Eugenics where lower castes were seen so beneath them they they worked them to death, used them in nerve gas experiments or valued their life so low to not care about taking them.
However the one thing that mankind has began to understand in relatively recent years is it's attempt to embrace equality, since equality would suggest that people can get along with one another. I prefer equality rather than of complaisantsy since of complaisantsy is Tyranically founded and usually leads to Rebellion.
