I guess you'll have to hope you don't need to find out. That would be the preferable situation, anyways, but the preferable never seems to happen...

And I can think of a number of reasons I wouldn't want to see your world. Dress code for one.

Joking aside, it's one thing to hop back in time, it's another to jump forward. I think I've seen enough in Khan's world, that I would like to return home and pretend I never saw it. Such a thing is a bit foolhardy, but at least I'll see things gradually instead of being dropped into the middle of them. The Nexus is shocking enough, your world could be what mine turns into, and I think that makes it more unsettling.
