UPN reportedly paid $10 million for the pilot - about four times what an average pilot costs and up to ten times what networks usually contribute to them. (Mara Einstein, Media Diversity, p. 190)
The show makes reference to "Element 115" as the fuel for the Sphere. Between July 14 and Aug. 10, 2003, element 115 was discovered by Scientists from the Glenn T. Seaborg Institute and the Chemical Biology and Nuclear Science Division at the Lawrence Livermore National Laboratory, in collaboration with researchers from the Joint Institute for Nuclear Research in Russia (JINR). It has an atomic mass of 295, with 180 neutrons, and isotopes with atomic masses of 287 and 288. The total quantity produced was four atoms. As of 2004, it has not been officially named, but has a provisional designation of Ununpentium. In the periodic table, it appears in the same column as the elements Nitrogen, Phosphorus, Arsenic, Antimony and Bismuth and shares many of their chemical properties. The use of element 115 in this series is a reference to an interview with Robert Lazar, who claimed to be a former Area 51 worker. In this interview, he said that Ununpentium was an element used by UFOs to produce anti-gravity effects. Element 115 was officially recognized by the IUPAC on December 30, 2015. Its discoverers were given the chance to name the element. They suggested langevinium (after Paul Langevin, a 20th-century French physicist) and moscovium (after the Moscow Oblast, where the discovering laboratory in Dubna is located). The latter was formally accepted on November 28, 2016. Its assigned atomic symbol is "Mc".
