Element 115 as a Propulsion Fuel: Chemical Viability Challenged by Decay, Scarcity, and Melting Point Constraints
To the point
Bob Lazar’s claim that Element 115 powers alien propulsion is chemically implausible because the element is highly radioactive with no stable isotopes and millisecond half-lives, only about 50 atoms have ever been observed since 2003, and its melting point is predicted around 400°C—far from his 1740°C figure—making gram-scale, long-term storage impossible as fuel.
