I do not see that a worm hole could get any where in this universe --any faster than one could go by regular space--since space seems to be almost flat. The only questions that I wonder about are the branes in String Theory which fill space. [You need branes for the ends of open strings to hold onto]. Also there are the sort of extra folded up dimensions in String Theory. What I am wondering about is if these go anywhere? {String Theory seems the best thing out there in terms of understanding the basic nature of pace and time.}
Another thing that I can see could be helpful in getting around in this universe is a black hole. What I means is that black holes carry around space, and that is what makes the powerful emitters [sometimes]. [Cygnus X-1 is like that. It is powerful emitter of X-rays--that mass comes from its partner. It was a binary system at first.]] I mean inside nothing can leave. But there are black holes that carry around space. And when space is being carried around there is no upper limit about the speed of light. Since it is just space, not matter. So anything attached to space when space is moving around can go at any speed since from its point of view, it is just standing still. It is space that is moving.
