Interesting idea.  I've seen numerous shows regarding this 11 Dimensions theory.  I forget–why 11?  String theory also looks enticing but will remain in the realm of speculation.

To quote one of the researchers: "We are still a very long ways off before we could create something to harness that type of energy."  No kidding!  Personally, I like the idea of using wormholes to travel vast distances.  Though highly speculative, to me it has a bit more going for it, though it comes with its own set of problems. 

It is wonderful to speculate that mankind will someday be able to travel through space, but being a pessimist I simply can't see it happening.  But then again, Star Trek has shown that what we did not think possible 20 years ago has come to pass.  Although a long way from teleporting humans, physicists have accomplished this seemingly impossible feat with photons:

I'm sure that scientists will continue to try and discover ways to propel humans across the galaxies.  Even if, for now, it's just in the theoretical stage, what a fascinating concept it is!  But I doubt if we will see this happen, if at all; certainly not in our lifetimes.  This may be a case where the journey to achieve the warp speed concept will prove to be more enlightening and fruitful than anything we can currently imagine.  Who knows what might be discovered along the way?
