How a worm hole works (metaphor):
Think about taking a sheet of paper (9x11, in this exacmple). Now, if you want to get from the top middle part, as shown here:
||||n||||
|||||||||
|||||||||
|||||||||
|||||||||
|||||||||
|||||||||
|||||||||
|||||||||
||||||||| (each n represents one point of interest)
||||n||||
It would take you -exactly- 9 spaces between the two, lets say meters, to get there. So, you would have to walk 9 meters to get to the other side. But now, lets think about this as the word 'wormhole' means it to be implied; as if you had to go 9 million miles. If you had to travel, at any speed achievable today, that far, how long would it take? Years.
So a -theory- has arrived, many years ago, not sure by who, though; it says that a wormhole is the folding of the material making up the universe, and therefore you can get from point N1 to point N2 (N1 is initial point, N2 final) in a fraction of the time. Specifically, the time it takes to actually warp the cosmos and -walk- through it.
