Traveling in a New Dimension

Time travel is something a lot of movies play around with. But time travel is nothing to play with in reality. It can influence the past, influencing the future, and present. If we go back in time, we could mess up the present. If we go forward in time, there is so much unknown that it would be extremely dangerous. So obviously it is a risky and dangerous idea in general. But, plenty of movies capture what would be wrong with time travel, think about it. There isn't a lot of time travel movies where the time travelers don't end up in some sort of predicament, I guess it wouldn't be interesting if they traveled back in time and everything went according to plan anyway.

So what is the point of time travel in general. Well, travelling back in time would be used to study history, prevent something historic from happening, or for self gain, kind of like the plot in Back to the Future movies. Honestly it wouldn't be that hard to make a living traveling back in time. If you just brought your cell phone back to the early 1900's it would amaze everyone. Go back any farther and it might scare people, some may call you a witch and burn you for your cell phone. But dangerous problems also arrive when traveling to the future. How do you know when you travel forward in time, Earth will even be there. What if aliens came with a death star and blew Earth up. You would have a giant problem as your gasping for air out in space.

But that brings me to my next point/problem/confusion about time travel. Say I traveled forward in time, 2 years. Assuming the time machine works the year would be 2016. But where would I be in 2016. When I came out of time travel am I where I was when I began traveling, because with Earths orbit I wouldn't be in the EXACT spot I was, again, I would be floating in space dying. So if a machine were to exist, we would need to make it place you on Earth, but even at that what if you time traveled back in time and you were placed inside of a building that used to be standing there. Not inside the building like in a room, but inside the wall of a building, or ceiling, or floor.

All of this is the confusion I have with time travel in general, and if you know the answers then go ahead and tell me. In my opinion, I hope that time travel never does exist, because if it did, all of these problems are a concern. But if you think about it, if time travel did exist, wouldn't someone from the future have traveled to the past at one point. Maybe there is a rule against it, or maybe, people from the future visit us all the time, we just don't know it. As long as they dressed the part for walking about in 1814 or 2014, there would be no way of telling where they came from, or WHEN they came from.
