Element with the atomic number of 115
Moscovium is a synthetic chemical element with symbol Mc and atomic number 115. It was first synthesized in 2003 by a joint team of Russian and American scientists at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia. In December 2015, it was recognized as one of four new elements by the Joint Working Party of international scientific bodies IUPAC and IUPAP. On 28 November 2016, it was officially named after the Moscow Oblast, in which the JINR is situated.Moscovium is an extremely radioactive element: its most stable known isotope, moscovium-290, has a half-life of only 0.8 seconds. In the periodic table, it is a p-block transactinide element.

More importantly, there allegedly is talk about stabilized Muscovite that exists as other elements that can form into Element 115 usable for gravity drive purposes:

"The following hypothetical reaction displays the maximum theoretical atomic mass of an Element 115 Isotope that could be produced from combining an Americium-243 nucleus with a Calcium-48 nucleus. The following reaction assumes no neutrons were liberated during the process of the reaction:
95Am243 + 20Ca48 → 115UUP291 → 113UUT287 + 2He4 → ...
The following reactions are the actual reactions that took place in the laboratory by bombarding Americium-243 with Calcium-48, which resulted in the two Isotopes of Element 115, indicated below, being identified.
95Am243 + 20Ca48 → 115UUP288 + 30n1 115UUP288 → 113UUT284 + 2He4 → ...
95Am243 + 20Ca48 → 115UUP287 + 40n1 115UUP287 → 113UUT283 + 2He4 → ..."
there allegedly is talk about stabilized Muscovite
For a long time there has been talk about an "island of stability" ([snip] the isotope lawrencium 266... has an astonishingly long half-life of 11 hours [/snip]) starting about element 126, based on the theory and experiences that gave us the Periodic Table. The point is, what Lazar said about element 115 (and years ago he wasn't sure whether it was 114, 115, or 116, but said it was "right in there") is a smoking pile of BS.
