I'm putting this in Treklit because the Red Matter backstory is from Countdown. Also, the timeline/era it's from is only being explored in the novels for the foreseeable future (of course, the novels may ignore Countdown and do their own thing, but still...)
In Countdown, we're told Red Matter is a Vulcan invention made from the rare mineral Decalithium. They're unwilling to share this technology with Romulus, even in the face of their cousins' desruction.
But shouldn't Red Matter be highly illegal? It would appear to be based on similar principles to the subspace weapon used by the Son'a against the Enterprise in Star Trek: Insurrection. In that film we're told that subspace weapons are banned by the Khitomer Accords. Were the Vulcans developing illegal WMD's?
Also, FWIW, we've seen similar weapons in Treklit before: The Grigari from the Millenium trilogy used a "singularity bomb" to destroy the Guardian of Forever planet and surrounding space fleet in an alternate 2400.
