"According to Lazar, the reactor was a matter–antimatter reactor. It required a piece of exotic matter machined into a triangle—element 115. Lazar talked about this back in the early '90s, and today we’ve actually identified it—it’s called Moscovium. We can synthesize it, but we don’t have a stable isotope. The craft he worked on used a stable form of element 115, which was essential to the reactor. I personally believe that Bob was telling the truth. I am persuaded that his testimony is true."
