Re: Gaping Hole of Troiyus
In Trekverse, there appears to be at least 2 other periodic tables as "di"-lithium and "tri"-lithium seem to suggest. There may also be "di" carbon, "di" iron, "tri" magnesium, and so on. Maybe these other elements cannot be replicated, for some reason. The gemstones in "Catspaw" may be made up of the "common" elements which can be replicated, hence Kirk's comment on being able to manufacture them.
