As far as I'm aware, the technologies inscribed there are based on already existing lore. The Storta in particular, if you give the infocard a quick read over, is powered by a singularity reactor which goes nova whenever it's turned off.
Humanity has also managed to create antimatter weaponry, notably in the form of Battle Razors, Mortars, SNACs, etc.
I don't know about dark matter, but maybe there's an explanation there as well. The Disco Freelancer universe is a science fiction nuthouse, honestly.
