[Phantasm]

It seems to me that the OP's idea is "give me something that has never appeared in any Star Wars book, comic, movie, video game, or tie-in resource", and seems to be using both the old EU and the current Disney-canon to shoot down ideas.

At this point, I think there's nothing left! There are even Elder Things, interdimensional travel, and time travel in various EU sources. The same book that gave us Elder Things and interdimensional travel also included a white dwarf star that had cooled to stop radiating heat and was breaking up (The Crystal Star, by Vonda McIntyre; IMO, it reads like a novel intended for independent publication that had Star Wars hammered into it due to a contract with LucasArts than a true Star Wars novel).

So even if this scientist was studying the process of extreme advanced solar decay, well, "it's been done already".



Anyway, give us the time frame the game is set in, and if some stuff has already shown up in a later time frame than the game, please don't dismiss it out of hand because "it's already been done". There's a good chance your character may be the one to make the breakthrough needed to make it work!
