It is rumoured that reverse engineering of alien spacecraft recovered from crashes in USA in the 1940s, if they occurred, could have been powered by element 115 which would enable anti-gravity propulsion. Bob Lazar, who claimed to work on alien technology in a secret base S4 a few miles south of Area 51 in Nevada, has asserted that moscovium functioned as a gravity wave generator for UFOs, but is it all rubbish?
Is it conceivable that element 115 could have a property enabling it to cancel or reverse gravity? Would the element have to disable the Higgs boson which gives particles mass and therefore subject to gravity? The element has not been manufactured by US scientists in sufficient quantities to test it properly.
