BTuna, yes that's an example of the kind of weird inter-dimensionality involved. Many, many highly-trained human observers (pilots, law enforcement, military, air control personnel) have had these observations of UAPs appearing, vanishing, suddenly reappearing, transforming from one object into 3 or 5, rejoining into one object, etc. Bizarre, but utterly explicable if that alien intelligence and its manifest "craft/vessel" are making use of just one extra dimension of space.
Michio Kaku, who wrote a textbook on Superstring theory for physics grad students, also explained all of this for the interested lay reader in his classic text of the early 1990s, Hyperspace. Other authors have also explored the kinds of capacities that would be available to anyone capable of acting within just one extra spatial dimension. They'd have "god-like powers," as Kaku wrote.
Obviously, the technological, religious, political and cultural implications would be enormous and unpredictable.
Ezra Klein just touched on some of these implications in his piece for the NY Times a few days ago....
