the remarkable speed of his spaceship. The earth is now 1,000 years older, while the traveller is only 500 years older. Thus, time moves along on earth as usual. Much like the train example, the earth is like the first train, while traveling to the sun is the second train. Einsteins theory proves that time travel is possible, lets look at the phenomena that takes us even closer. A black holes is formed from the gravitational collapse of a massive star. Once it has been created, gravitational forces continue pulling in space debris and other matter; this adds to the mass of the core, making it more powerful. Because of this, black holes compress anything that enters its clutches. So what would happen if someone decided to enter a black hole? Black holes act like a one way street in that they only allow objects to fall into them, not out of them. If someone decided to enter a black hole, his or her molecules would compress to the point where the portion of his or her body that is passing through the hole would be compressed like a noodle. This is known as the spaghetti effect. As of today, black holes have been found in space, but far too small and untable. If black holes act as an entrance, white holes act as an exit. White holes, on the other hand, are much like black holes in the way they are formed. The difference is that objects are pushed away from the center instead of towards the center. An interesting point here is that white holes expand matter due to its negative gravitational properties. At this point however, white holes are purely theoretical. A black hole and a white hole are connected by a wormhole, the key to time travel. A wormhole connects two points in space with no regard to time. If you picture space as a piece of paper, a black hole and a white hole would be represented by two holes on the surface. If the paper is folded in half, the two holes would connect somehow. Picture a funnel-shape...
