With a new focus on physical proof via the scientific study of known UFO crash artifacts, Jacques Vallee has been organizing isotopic and elemental analysis of evidence. Some of the samples Vallee had tested were found to be outside of the terrestrial norm, and so pure in their form that they appear to be fabricated in a method not possible on Earth. There are many remarkable alien artifacts that have been hidden away in secret vaults, they could re-write history as we know it. These artifacts are highly controversial and need to be tested. We are constantly finding new UFO artifacts that defy our current understanding of the universe.
