In addition to which this article may provide some insight on this topic:
Bob Lazar is a central (and highly controversial) figure in recent discussion about UFOs. Lazar claims to have worked at Area 51, and to have performed reverse engineering on crashed extraterrestrial spacecraft there. The publicity surrounding his revelations is one of the major factors in putting the theretofore neglected base "on the map" of popular myth.
In the 1980s Lazar claimed that the placeholder element ununpentium (Uup) was the fuel that enabled extraterrestrial craft commonly called flying saucers or UFOs to travel enormous interstellar distances (although his unconventional wisdom distinguishes between larger craft and smaller shorter-range "shuttle" ships). Uup's role was twofold. Firstly it provided an energy source when, under particulate bombardment it would step up to ununhexium and then decay, including a small measure of antimatter in its decay product. Its second function, discovered later, allegedly lay in the intense strong nuclear force field of its superheavy nucleus. Extending just barely usably beyond the atom's perimeter, this, properly amplified, could be employed as a variant of gravity, or "Gravity B" as he claimed project scientists reverse-engineering the craft referred to it, and thus be employed to "shape" a craft's relation to the gravitized space around it. Lazar said this property explained the "triple dome" structure frequently shown in sketches and photographs of saucer-shaped UFOs - Lazar believed these to be the crafts' gravity amplifiers.
Ununpentium he described as a very heavy dull orange metal which had to be properly machined for such use. Lazar ascribed the elements absence on Earth to the fact that the supernovae in Earth's region of the galaxy were insufficiently massive to produce nuclei of this density, unlike other parts of the universe inhabited by the adventurous but to date comparatively reclusive extraterrestrial visitors who could employ it. A significant supply, he claimed, was acquired through direct exchange by unacknowledged supersecret US government operations in the Nevada Test Site at Area 51.
Many of Lazar's statements have been criticised as inaccurate or unfounded, and his grasp of physics has been questioned. Lazar claims to hold advanced degrees from Massachusetts Institute of Technology and California Institute of Technology, but appears on the alumni roll of neither institution. Lazar's supporters allege this discrepancy is the result of a government cover-up.
One objection to Lazar's report of the element was that while Uup occurred in the atomic number range postulated for greater stability, the terrestrial experiments noted above suggested a half-life still on the order of seconds rather than years. This objection, however, is answerable on at least the ground that different stabilities are attributable to the different isotopic compositions predicted achievable only under distant stellar formation in contrast to those more unstable forms resulting from collision of stable elements by conventional means.
