Do time machines really exist?
I believe that they really exist. Even physicists are on the side of time travel; stating, unequivocally, that if one were to go faster than the speed of light they would go backwards in time. Also, stating if one were to travel beyond the speed of light-one would be thrust backwards in time! The only problem being that it would take more energy than the universe could produce to travel at or beyond the speed of light, due in part, to the incredible resistance against the craft as it approached these speeds. We even practice a form of time travel as we gaze at the moon or sun; seeing it in the past as the light takes time to reach the retina over the great distances between astronomical distances at light speed.
