Actually, it is easy in theory to travel forward in time, its getting back that is theoretically impossible. In Einsteins theory of relativity, the faster you are in motion compared to something that's at a fixed point in space, the slower through time you move (might be why people that exercise live longer...). Say we found a way to travel at the speed of light. The person traveling at the speed of light would be moving significantly faster than the people stuck on Earth. Einstein theorized that the closer to traveling at the speed of light you got, the closer you were to being at a point where time stopped, which is one of the many reasons why he believed that it is impossible for us to reach that speed, the other two main reasons where that as you travel faster, you actually gain mass (jogging makes you gain weight while you jog... hrmm...) and it requires more energy as you go faster (ok, so the jogging's not a waste now...). As you approach the speed of light, the mass increase and energy needed to maintain the speed become infinite.

Back from the tangent, Einstein's theory is that you can easily move forward in time by comparison just by moving faster. This actually has been proven using only two atomic clocks. Atomic clocks are the most accurate clocks in the world, they always keep time perfectly and there is very little possibility of them being too slow or two fast by any increment of time (they're the perfect clock). One of them is stationed in one of the forts around here somewhere (not fort worth, the clock's not worth that much...) and the other was mounted on a military cargo plane that made frequent round world trips. After about a month, the compared the times on the two atomic clocks and the one on the plane was about 5 mins slow (some stories say the experiment was done on satellites in space... gotta love how much our government tells us). After a month, the time the clocks would normally be off by would be less than a second difference.

Now this puts a damper on space travel, as travel from one planet to the next would also cause us to travel through time as we go, so going to the next solar system and back would make everyone we know on Earth decades older than us when we return. But alternatives are another discussion.

My theory on why we can't travel backward in time is that most people would travel back in time to intentionally change an event. But if you were to go change that event on purpose, then your history would be changed and you would have no reason to go back in time to change the event because it would have already been changed, therefore you wouldn't travel back in time to change it, making the event take place anyways. The only way someone could go back in time is if it was unintentional, leaving them with no reason to travel back, and if whatever they did in the past had no effect on their future, giving their life no reason to alter from what made them go back in time in the first place. If you know anything about humanity, that is an impossibility.

hehe, sorry I haven't posted one like this in a while, there just haven't been that many posts like this worth going on a rant about.

I wish I could go back in time changing and correcting certain things, staying in that era of time, being happy.

Butt if you went back and changed stuff so there was a new out come, how would you ever know you changed it- if the bad stuff didn't happen? Also what if the change lead to something worse happing in the future? Now the ideer of going back to a time in your life where you were happy sounds good but then again think of all the people and things you interacted with after that time that molded the current time or future. By changing any single event in the past you in-fact might change the entire present for many people...All the things that you have done for people that unknowingly or knowingly influenced their lives and made them make some sort of choice would never have happened so there are more changes that happen...It's a huge chain of events that each life is linked to.

String theory deals with some of this time space stuff. It is pretty interesting stuff even for a simple country boy like me
