Of course your input matters, and I was actually hoping Tony would have a part since science is his area. Anyway that actually solves a question in my mind about 'well why wouldn't we just go to an alternate dimension 'cause fuck everybody, Earth rules!' but the spacetime suspension thing is perfect. And as a whole this seems like a pretty sophisticated plot~ but still uncomplicated enough that I could summarize it in the game info and not scare off potential players who don't read the comics.
Do you have your heart set on playing it out or would you be okay with skipping ahead to the aftermath?
