Will man one day have the ability to travel through time? Let us begin by examining the effects of such an accomplishment.

If we could travel to various time periods, we would most likely alter the entire time line irreparably. To put it simply, our existence would be a mess! There would be disruptions in temporal continuity. Many people would probably be "wiped out of existence" all together! There are still many other paradoxes that I have not yet mentioned, but shall explain in what follows.

If one was to travel back in time and meet himself, what would happen? Would this individual be divided into 2 separate, yet identical beings? Or would the person grow rapidly younger and maybe even loose his memory of the time in which he was originally living?

Could a person go back to a time before he was born? I believe that many problems would arise if this were attempted. First of all, how could the person exist, yet not exist at the same time? Here again is the possibility of growing younger while time traveling; going from your current age to a single cell, and then into NONEXISTENCE.

Let us say, for example, that someone CAN travel to another time. This raises another question. If someone was in another time for 2 days and decided to go back to the time period from which he came, would 2 days have passed in his original time? Or, would he "disappear", spend these 2 days in the other time, and "reappear" instantaneously? I believe that it would be NEARLY instantaneous, though there may be a millisecond or microsecond difference.

And what about the sensation of time travel? How could one handle the extreme conditions and sensations of it? Unless there is some sort of protective shield, I do not believe a human could handle the transient period from one time to another.

Another thing; if time travel WERE created, wouldn't this present time line be messed up already. It seems that there are no massive sudden disappearances of people or parts of the time line for that matter that I know of! Unless, that is, these temporal paradoxes that we're all so worried about never happen. Maybe there are people right now walking among us from other times, and not saying anything about it. Maybe Tesla & Einstein were from other times!

The next topic that comes to mind is the future. First of all, is/ are future events presently indefinite? I don't believe they are. I think that many major events in time are "planned" and definite, though we cannot know them now. Let's just say they WERE indefinite, just for the sake of argument. If we attempt to go into the future, we may just hit some kind of barrier. If we try to go past this barrier, we may be plummeted head-on into eternal non-existence in this plane. If the time line is planned, the alteration of it would have drastic repercussions.

In my opinion, I believe that time travel shall never come into being. Let's leave the time line up to the supreme being.
