In Popular Culture
(U) Ununpentium has been theorized to be inside the island of stability. This probably explains why it was mentioned regularly in
popular culture, especially in UFO conspiracy theories. The most popular account of elemen.t 115. from Bob Lazar, is considered
pseudoscience,l7J Although it is reasonable to suppose that element 115 will have unique properties. there is no openly available
empirical evidence to back up La7..ar's claims.
