I recently watched a special on the discovery channel regarding Stephen Hawking's ideas of whether time travel is possible. He comes to conclude that time travel into the past is NOT possible. This is because time travel into the past would create a paradox. The example he gives is that if we were to build a gun and then use that gun to shoot ourselves when we were building the fun, it wouldn't make any sense. However, Hawking ventures to say that time travel to the future IS possible. If we can speed atoms to near the speed of light, than we can truly time travel. This discussion of time travel has got me thinking about earlier in the semester when we talked about time. If we were to time travel, would it prove or disprove that time exists?
