Although folding space and its resulting wormholes have yet to be documented, there continues to be a healthy discussion in the scientific community about its existence.  Stephen Hawking gave a lecture which touches quite a bit on the possibility of wormholes in folding space, and the implications of human travel through these wormholes. (Hawking)  One main discussion point around this amazing phenomenon is time travel.

In theory, one would travel so quickly through a wormhole, that one would be moving faster than the speed of light.  Professor Hawking puts it this way: “if you can travel from one side of the galaxy, to the other, in a week or two, you could go back through another wormhole, and arrive back before you set out.”(Hawking) 

Time travel has actually already been demonstrated.  Scientists who studied passengers on the space shuttle proved that, because of the shuttle’s high speed, time moved more slowly for those on board. (How time travel will work) 

But how can space “fold”?  Well, simply put, “masses that place pressure on different parts of the universe could eventually come together to form a tunnel – this is a wormhole.” (How time travel will work)  Having a visual also helps in understanding this concept. Wormholes are also known as “Einstein-Rosen bridges”, and have some basis in Einstein’s theory of special relativity, as well as the spacetime continuum.
