I've been watching this vid on repeat trying to fully comprehend what's happening. This is another vid trying to explain the same thing - https://www.youtube.com/watch?v=UnURElCzGc0 https://www.youtube.com/watch?v=UnURElCzGc0 I really want to believe this is possible and this is how we'll be able to travel far into space. Like how we have to spend time walking around a very long wall when a bird can just fly over it in a fraction of the time, we wouldn't have to think about traveling light-years because there would something else we can do that's faster than a straight line.

That's not very likely, because you don't have to walk around some kind of obstacle to get to a star. Even as a bird, you still have to travel the full distance to your destination. You could make a shortcut in space, which is called a wormhole. You can either make one using extra dimensions, or in 3 dimensions with negative energy to stabilize it, but neither of those seem to exist.

  Unless 3d space is 'wrinkled'; in 4D you could travel straight there. Imagine a crumpled sheet - the 2D traveler would have to trace a route through all the convolutions to reach the other end of the sheet. The 3D traveler may only have inches to go. 'A Wrinkle in Time' was a story about this.

    You'd just have to hope that the place you want to go to is wrinkled up so that it's next to you, and not still far away.

      From my vague recollections they were somehow causing the wrinkles to be close together. It has been years since i've read the series though.

      Actually going anyplace at all that way would be hugely exciting.

You might find NASA's page on warp drives interesting. http://www.nasa.gov/centers/glenn/technology/warp/warpstat_prt.htm http://www.nasa.gov/centers/glenn/technology/warp/warpstat_p...
