Time travel- well obviously there are two types we'd like to find out are possible, to the future and to the past. Well, time travel to the future isn't as lavish as most people would like to think. You don't get to a future society and see how you turned out. It's more of your point of view being altered from that of "normal" time experiance on earth. To travel to the future you will just experiance time much slower than your companions on earth. This ,of course, presents time as something that can be altered ,which it is. But according to this same concept to travel to the past you must do one of two things. The first is experiance time as it runs backwards(if it's even possible). Or travel through a rip in space-time hopefully landing somewhere in the past. The first way would prove to be vey difficult considering that the time traveler will experiance time running backwards in the same manner as the place he's visisting. For example if he could some how get time to run backwards ten years into the past then start running forward again the traveler would have gotten ten years younger. The other way just gets us into some pretty complicated physics. Tell me what you think.
