Zxjkl: Exactly. It's unlikely the particle accelerator could be weaponized, but presumably there was a chance it could have revealed new physics that could give the organics an edge. That's the only reason I can think of for the Reapers to prioritize it. As for Rothla, yeah, it's pretty weird, but hey, perhaps the krogan were testing a super-gigantic warp bomb, something outside what other races had ever built, and got a really nasty surprise.

Feck: The Mass Effect universe manifestly does *not* work according to the laws of physics as we know them. It's fairly "hard" sci-fi as such things go, in that all the exotic physics is confined to the titular mass effect fields and the element zero substance used to generate them, but these things are still total nonsense according to present-day physics. The writers put sufficient care into building their universe that it's fairly self-consistent, but they also dropped a few very definite hints that the description if its physics that we, the players, are given is incomplete.
