Interdimensional Hypothesis

Vallée's heresy: they're not from far away. They're from right here, next door.

For decades, the argument about UFOs had exactly two settings: they're ours, or they're aliens from another planet. Nuts and bolts. Metal ships crossing light-years. And then two of the most credible people ever to study the subject looked at their own data and said — quietly, carefully — maybe it's neither. That's the interdimensional hypothesis, and here's the documented part you can hang your hat on: the people behind it were not fringe cranks. J. Allen Hynek was a professional astronomer who ran scientific consulting for the U.S. Air Force's Project Blue Book for years. He started as a skeptic whose job was, essentially, to explain sightings away. Jacques Vallée was a trained astronomer and computer scientist — a real one, who helped build early network mapping at Stanford — and he became one of the most rigorous catalogers of these reports in the world. These are the thinkers. Their credentials are not in dispute. So here's where it gets strange. As Vallée worked through case after case, he noticed the phenomenon behaved less like a spacecraft and more like something that shouldn't obey ordinary physics at all: objects that appear and vanish, that seem tied to consciousness and place, that leave contradictory or absurd traces, that recur with the logic of a story rather than an expedition. Interstellar travel — the sheer distances, the sheer numbers of sightings — started to look like a bad fit. Vallée proposed instead that the phenomenon might originate from somewhere adjacent to our reality: another dimension, another layer of existence, interpenetrating our own rather than flying in from a far-off sun. Hynek, late in his life, publicly entertained the same direction, suggesting the answer might require new physics or a "parallel reality" rather than simple extraterrestrial visitors. That idea is exactly why this node sits beside Portals. If the phenomenon comes from an adjacent reality, then the "portal" people describe at anomaly sites is just the folk-name for the seam — the place the two realities touch. The interdimensional hypothesis is the room; the portal is the door. They are two halves of one framework, and this record links them deliberately. Now the honest boundary. The interdimensional hypothesis is a HYPOTHESIS — an interpretive proposal, not a proven mechanism. There is no experiment that has demonstrated another dimension delivering UFOs, no instrument reading that confirms it. What's DOCUMENTED is that serious, credentialed investigators — Hynek and Vallée foremost — advanced the idea in print and defended it against the assumption that "unexplained flying object" must mean "alien starship." That intellectual move, made by insiders rather than outsiders, is the real, citable history here. And it opens a door of its own — because once Vallée started reading the phenomenon as something woven into human experience across time, he went looking backward, into the fairy-faith and abduction folklore of earlier centuries. That's your next thread, the Old Encounters. On the map, place the Interdimensional Hypothesis between Portals and fairy-lore — the conceptual hinge of this whole record.
