EXCLUSIVE: Why element 115 can not be used for antigravity

He probably read about theories concerning element 115 in scientific journals during the 80's. IMO, Bob Lazar is just vying for publicity and book sales. There is also a high probability that he gets royalties from other authors for detailing his story. With his credentials, he may have worked at Area 51, as a janitor, but his take on a UFO is pure fabrication.

"However, this has not been observed in element 115."

It has not been observed in element 115, because the manufacturing process is critical. The process is very explicit and requires exact precision in order for the nucleons to hang. Your end result is a small triangle with exact mass necessary.
