Bob Lazar on physics: what the evidence says · JRE #1315
“Element 115, the fuel they had, was stable. In other words, it didn't decay, it wasn't emitting radioactivity”
What the evidence says
Lazar claimed the element 115 sample he described handling was a stable isotope that did not decay or emit radioactivity. Element 115 (now named moscovium, symbol Mc) was first synthesized in 2003-2004 by a joint Dubna-Livermore team via the nuclear reaction 243Am(48Ca, xn)291-x115, and its identification, like that of all superheavy elements, depends on detecting its characteristic radioactive decay chains in a particle detector -- the opposite of non-decaying. All moscovium isotopes produced and confirmed to date are extremely short-lived, with half-lives on the order of tens to hundreds of milliseconds up to roughly one second, and physicists studying the region expect any longer-lived isotopes near the theorized "island of stability" to still be radioactive, just less so, not truly stable. No stable or non-radioactive isotope of element 115 has ever been produced or is predicted by current nuclear models. The scientific record therefore directly contradicts the claim that a stable, non-decaying sample of element 115 could exist or have been used as described.
