OK you guys may not believe this but its true. For my final Physics 312 paper I wrote about time travel and here is the most plausible way the best I can remember it. First off, time travel having to do with going faster than the speed of light is made up by the media and movies. Going faster than the speed of light really isnt possible. Time does slow down the faster an object travels, theoretically reaching 0 velocity at the speed of light but at this velocity all matter becomes infinetely dense, hence the fact that practically speaking, speed of light travel will be impossible. Now what is possible are holes in space. Dont laugh and let me explain. Space, like time and all other dimensions, is simply a dimension that is percieved by us. Scientists right now are just realizing this and beginning to study this and Einstien realized this 60 yrs ago. Einstien and and dude named Rosen or Rosenberg created and proved a theory about how to bend space using magnets. This theory is called the Einstien-Rosen Bridge. This is physically possible time-travel. It works like this in a simplified matter: First, you need to harness the energy of a star, like our sun, into a magnet of any size. A star simliar to ours has a gravitational pull but has a relatively neutral magnetic pull. So you take that energy and put it to use in a gigantic magnet (lets say positively charged) then you take another magnet of equal power but of a negative charge and put it on the other side of the galaxy. Then you simultaneously activate both magnets. What this does is it bends space and brings the 3 and 4 dimensions together into 1 point through magnatism. BUT the problem is this 'bridge' is only open for a split second so it is necessary to inject anti-matter into the bridge to keep it from collapsing in on itself. This is a problem because as of now, man has only been able to create a few atoms of anti-matter because of its incredible instability. So you inject anti-matter into the bridge to keep it open and VIOLA you have a bridge over space and time to any point in the galaxy. When you pass through this bridge you bypass time as you are traveling a million times faster than the speed of light because you are passing from one point in space to another simultaneously and you are bypassing space by doing said activity. So yeah, thats pretty much what I remember from my paper. Not that anyone cares and I dont really care either. It was just a paper for my class but it was somewhat interesting.
