There are those that believe, based upon a scientific POSSIBILITY, stated as theory, that it is feasible to travel through time. First let's be clear; any means of conveyance can be deemed a time machine and at any time that we travel from point a to point b we can be said to be traveling in time. But that is not really the issue at hand in this debate. The thrust of the question is, I think, whether it is feasible or even possible to truly travel either backwards to the past or forward to the future. The truth is; we can't.

Oh, the myriad problems. Where does one begin?

How about we begin with the trouble in going backwards? After all, that's what a great many people would like to do; you know, go back and fix things or change things that we didn't like or could do better. Well, the trouble here is; what about Uncle Bob and Aunt Sue? Are we going to assume that because you transport yourself through time back to their tenth anniversary to ensure that they don't drive and thus avoid the terrible accident that killed them that night that they will cooperate and simply leap from their graves, reanimate themselves and be at the party for you to stop them from driving? Are you insane?

Yes, you can argue the string theory from now till doomsday and suggest that, like individual cars of a train, the occasion you want to visit in the past exists just as it did back then only a few cars back in time. Well, let's see,...if that's true then in each of those cars of the train there must exist another one of every person that lived at that time carrying on a life that is as real and tangible as the one they live now. It begs the question; at what point in time does one car end and another begin? It begs the question; what do I do when I run into myself in the other car I'm visiting and are we both really there? Are there two of me or only one? Would I be younger or the same age? Face it people. You have to be insane to really buy this as possible. Forget feasible.

Let's journey now into the future, shall we? As if we could.

Yes. You could get on a rocket and leave the Earth, attain light speed or greater and once having done so, return to the Earth. The theory says that having done all these things you will have traveled very far forward in time. Well, there are some very real problems here, too. First, you aren't going to attain light speed. Why? Because we don't possess the technology to allow you
