Time travel is no longer regarded as strictly science fiction. For years the concept of time travel has been the topic of science fiction novels and movies, and has been pondered by great scientists throughout history. Einstein's theories of general and special relativity can be used to actually prove that time travel is possible. Government research experiments have yielded experimental data that conclusively illustrate that fast moving aircraft have traveled into the future. This phenomenon is due to the principal of time dilation, which states that bodies moving at high velocities experience a time that ticks slower than the time measured at zero velocity. Not as much time elapses for a moving body as does for everything else. Phenomena known as wormholes and closed time like curves are possible means of time travel into the future and the past. Traveling into the past is a task which is much more difficult than traveling into the future. This feat has not yet been accomplished -to our knowledge- and its theory involves complicated scenarios of tears in four dimensional space-time, and traveling near the speed of light. Obstacles which prevent our hubris attempts to cheat time include our inability to move even close to the speed of light, and finding a source of energy as powerful as an exploding star. Simply because the proposal of time travel is backed by scientific theory, is no reason to expect that it is easily achievable. Numerous arguments are proposed that that prevent time travel into the past. Both common sense and scientific fact can be used to paint scenarios that become serious obstacles. Not to fear, we have all the time in the world to overcome these minor limitations.
Imagine if you will, that you are one of the people sill alive today that was born prior to 1903, when the first airplane took flight. When you were young the idea of flying would probably have been quite exciting. Some scientists believe that we may presently be living... [continues]
