Via my Paradigm-Grid, I am of the disposition/impression that «Propulsion» Technology is in fact, a /primitive/ technology that can only really go as far as the moon, but, any further than that, then, one would need Levitation-Technology or perhaps it could be called Gravitation-Manipulation Technology; then, like/believe him or not, then there is also that Dr. Steven Greer guy who talks about «electro-gravitics» a lot (and free-energy, which is also known as Zero-Point Energy, or New-Energy).
The fact that there has been over 70 years worth of scientific-progress and technological-advancements out of the U.S. alone, not even counting other countries, supposedly, suggests that, IF the human-species were truly advancing the way it should in a «sane» society, then, its productive-capabilities should be SO sky-high that, rather than transitioning from a time where one man of a house-hold could work a 40 hour week and still be able to provide for a whole entire family, house and cars and pets and all, even sending their sons and daughters to colleges/universities (not that those aren't just indoctrination-institutions full of cult-professors with only a handful of note-worthy exceptions who break the dogmatic-mould of the main-stream), everybody should actually be able to live in absolute-abundance, such that, the hours people work to be able to sustain themselves should be far less, rather than both spouses being forced to work full-time-jobs or even over-time-jobs just to be able to earn ends-meet (although now it is even often the case where the whole entire family is forced to work in order to avoid becoming homeless), the «homeless-population» should be a thing of the past (for more about the homelessness-crisis see Lauren Southern's video-documentary on the Homelessness-Industrial-Complex), various numerous other «world-problems» should be easy to resolve, but, apparently, the ULTIMATE-TRAP is this «psychological-mass-mind-control-brain-washing» that TWISTS the «perceptions» of the unwary into believing the EXACT OPPOSITE OF TRUTH which is the nature of the Quantum-Dissonance-Particles that «accumulate» within Energy-Cores (for lack of better description) of all Is-Beings who foolishly let themselves get «tricked» into CULT-Beliefs... speaking of industrial-complexes, Military I.C, Prison I.C. Censorship I.C., Homeless I.C., they ALL seem to have a few LCDs (Lowest-Common-Denominators).
