What would be scary is if the technology is extra-dimensional. What we perceive is only in the third dimension and the UAPs are only visible to us when they intersect with our space. They exist outside of our perceptual planes at the same time that they intersect with our perceptual plans, so they can easily intersecting presence is acted upon in ways that seem impossible to us.
Dude, don’t drink the bong water.
Would you believe that the Bible offers support for your well reasoned scenario? When Jesus rose from the dead He was no longer a four dimensional being, He was possessing dimensional variables which allowed Him to enter a locked and shuttered room without piercing any of the six sides tot he room, for instance. And the scene from Daniel chapter five also bespeaks a greater dimensional realm, as another example. And there are several more scenes which lend support to your reasoning. ... Well done!
I don’t recall the scientist but recall a talk on string theory and subatomic particles being multi-dimensional and not having the capability to view or detect.
As a Christian, multi dimensional makes sense to me and the concept of having a soul.
“extra-dimensional”
Or a parallel dimension. Another universe next to ours with intelligent beings able to pass into our time and space.
Stranger Things television show was based on UAP sightings I think.
