Zeta Reticulans grey's - Element 115 = ununpentium = Uup = The beings allegedly originate from the first and second planets within the Zeta Reticuli star system and are therefore referred to as Zeta Reticulans, popularly called 'greys'. For the propulsion of the studied vehicles, 'greys' claims that the atomic Element 115 served as the fuel. Element 115 (temporarily named "ununpentium" (symbol Uup)) reportedly generates a minuscule gravity field which can be tapped and greatly amplified because the field happens to extend just beyond each atom's outermost electron shell. Exactly how this field is accessed, however, remains unclear. But the end result is allegedly a highly directional gravity distortion field. Under proton bombardment, furthermore, it is claimed that the atoms of Element 115 produce antimatter particles which participate in a process of extremely efficient energy production for powering any and all systems and subsystems within the craft. The mass of the nuclear fuel aboard each craft was said to be approximately two kilograms and was enough to last for several years before requiring replenishment.
