I remember watching some program a while back that basically said wormholes can never be used for space travel, or traveling of any kind, unless you're the size of an atom. The program was basically saying the inability to create or use wormholes is a universal law, like gravity. Wormholes create paradoxes that could unravel the Universe! Well that's just my laymans understanding of it

But I do think there is something that can travel across the galaxies, and are already using it. It's mind. Close your eyes and see yourself traveling to another planet. Congratulations you're an astronaut! The interesting part is if you're willing to believe that mind exists on another layer of reality *astral*. In this case, if you can access this other layer with your full consciousness, you really are traveling to distant planets. The next step, is to have your body travel with you.

It all sounds impossible but I'm a believer that if we humans an imagine it, then it is possible on some level. Because I'm not sure how its possible for a mere human to imagine something separate from this Universe - when we are parts of it. We've imagined all sorts of crazy things, wormholes, time traveling, teleportation, dematerialize, re-materializing! All the great stuff of science-fiction.

So in my belief, all of these things must be possible - just not maybe 'here'.
