text: what is worm hole ?   do you want the extended answer or the short answer.   the short answer is a bit like this.  a worm hole is a hole in the space (not time) continuim that occurs at a fold in the universe that you can travel through at almost the speed of light. the other choice is a wormhole that leads to a diagonal universe that is mostly the same.  however a wormhole is a theoretical part of physics, and until either made or found can not be proved.   for the long answer try looking on nasa website but be warned, it will be long and confusing.
