Dilithium created and observed in the laboratory! Answered
According to a news report in Physics Today, scientists at Lawrence Berkeley National Laboratory have confirmed the creation of element 114 first reported by Dubna physicists in 1999.
As true afficionados may recall from the original Star Fleet Technical Manual (pictured), element 114 is dilithium, used to regulate the matter-antimatter reaction for warp propulsion. Unfortunately, with a lifetime of just a few hundred milliseconds, it's unlikely that crystals of element 114 will be produced any time soon.
