Okay, yeah, you have a point. I'm more focussed on just getting out and going travelling, but... we don't even know what universe we're in. Identifying our own universe and getting back there, if that's what we want, could be difficult!
Our best hope would be to figure out the technology that brought us here. If it brought us here, it should be able to get us home again. We ought to be able to retrieve the coordinates for each of us.
