Something that I didn't understand.....
Ok, if the building is always there in every version of earth, then why did the one girl say it was so imperative not to miss the "jump"? If you missed one jump, the building would still be there. Why wouldn't you just be able to walk in and jump with the building the next time around?
I don't know, they made it seem like you only have like 36 hours in each location, when if you stop and think about it, if the building really is a constant on every version of earth, there would be no reason why you couldn't stay as long as you wanted and simply enter the building when you were ready to leave and move with the next jump. Did I miss something or is this not the logical conclusion that one would come too if the building really was a constant? I didn't see anything that suggested you had to be in a particular version of Earth's building at a certain time to be able to jump.
