That sounds like a lot. Better spike that tea with whiskey.
Well, luckily I know quantum mechanics pretty well. My father has been researching the quantum realm for years - I'll ask him to give me everything he has, granted, it's very little since it's kind of an untapped resource as you know. But there might be a way to use it to tunnel into alternate realities, or even back in time. One way to stop the dimensional tear might be to figure out what caused it, go back, and prevent it from ever happening in the now.
