Element 115

Element 115 is the exotic, stable superheavy element Bob Lazar claimed in 1989 powered the gravity-manipulating propulsion system of the alien craft he said he worked on at a Nevada facility near Area 51, describing it as capable of generating an anti-gravity field when bombarded with protons. At the time Lazar made his claims, element 115 did not officially exist on the periodic table at all, which skeptics initially treated as strong evidence against his story. That specific objection dissolved in 2003-2004, when a Russian-American team at Dubna, Russia genuinely synthesized element 115 for the first time in a laboratory nuclear reaction, later formally named "moscovium" in 2016 — a real vindication of the element's basic existence that Lazar's supporters point to as evidence he had access to information not publicly known in 1989. The catch is the element's actual measured behavior: laboratory moscovium is a highly unstable, intensely radioactive synthetic isotope that decays within a small fraction of a second, nothing remotely like the stable, easily handled fuel source Lazar described. Both sides of the debate claim partial vindication from the same 2003-2004 discovery — Lazar supporters citing the element's confirmed existence, skeptics citing its confirmed, thoroughly un-Lazar-like instability.
