Jacques Vallée

Vallée began his career as an astrophysicist and computer scientist, working at SRI International and later in venture capital. He collaborated with Dr. J. Allen Hynek — the U.S. Air Force's scientific consultant on Project Blue Book — and developed his own systematic databases of UAP encounters beginning in the 1960s.

His most significant theoretical contribution is the interdimensional hypothesis: the proposition that UAPs may not originate from other star systems but from other dimensions or states of reality that interact with our own. This hypothesis accounts for aspects of UAP encounters — the absurdist elements, the psychic effects on witnesses, the apparent manipulation of perception — that are difficult to reconcile with a simple spacecraft-from-another-planet model.

Vallée has also been involved in hands-on investigation of physical trace cases — encounters where UAPs leave measurable physical evidence — and has collaborated with Garry Nolan on material analysis. He is a board member of various UAP research organisations and continues to publish.

• ▸UAPs may represent interdimensional phenomena rather than interstellar spacecraft
• ▸The phenomenon has a consistent core of physical and psychological effects across cultures and centuries
• ▸Some UAP cases leave physical trace evidence amenable to scientific analysis
• ▸The manipulation of perception and consciousness by UAPs may be intrinsic to the phenomenon, not incidental
