In 1989, physicist Robert Lazar went on Las Vegas television station KLAS-TV — interviewed by journalist George Knapp — and claimed to have worked at a classified installation called S-4 (Sector 4), located south of Area 51’s main base at Groom Lake, Nevada. Lazar stated he was hired to work on the propulsion systems of nine recovered craft of non-human origin stored in hangar bays carved into a hillside at the site. He described the craft’s propulsion as based on gravitational field manipulation using an element he called “Element 115” — an element that did not officially exist in 1989. His claims were treated as impossible science fiction. Several have since been corroborated.
Element 115 — now Moscovium: Lazar’s most specific technical claim was that the craft used Element 115 as a fuel source — a super-heavy element that, when bombarded with protons, would produce a stable nuclear reaction and generate a gravity wave that could be amplified for propulsion. Element 115 was officially synthesized and confirmed by nuclear physicists at the Joint Institute for Nuclear Research in Dubna, Russia in 2003 — 14 years after Lazar’s claim. It was formally added to the periodic table as Moscovium (Mc) in 2016. While the element exists only briefly in laboratory conditions and its properties are still being studied, its existence itself was correctly predicted by Lazar in 1989.
Employment corroboration: Lazar’s claimed employment at the Nevada Test Site and Los Alamos National Laboratory was initially denied by both institutions. Subsequently, a telephone directory from Los Alamos from the period was found listing Lazar’s name. His employment at a subcontractor level at the Nevada Test Site was confirmed through document research by investigative journalist George Knapp. The institutions denied him but the documents confirmed him.
S-4 and Area 51: Lazar provided the precise location and description of Area 51’s Groom Lake facility — which the US government officially denied existed until 2013. The geography he described matched CIA declassified satellite imagery released years later. The existence of the S-4 installation specifically — the sector south of Groom Lake — has not been officially confirmed, but multiple independent witnesses over subsequent decades have described anomalous activities in the same geographic zone Lazar identified.
