Ok. I've been thinking about time travel. It gets very complex. To a person who isn't traveling, it seems like some impossible tings could happen. But from the person in the timeline, time appears to travel in a straight line. And for the person traveling time appears to move in a straight line. What's even more interesting is that say you are the person moving forward in time as you are supposed to, not traveling. You could meet a guy on Thursday, see him get killed on Friday and then run into him again on Saturday. His personal time line might have begun on Thursday, he traveled to Saturday (where you were surprised as hell to see him) and then back to Friday where he got killed. Make sense?

Ok, the timeline starts at 1900 and goes thru 2030. Say our traveler is born in 2000. In 2030 he begins to travel. First he visits 1900, then 2000, then 1950 and then goes back to just after he left. He's the green line. But say we look at it from his point of view.

For him it's a straight line. But for our regular time line, it's impossible to properly represent in 2 dimensions. The red line attempts to follow but can't. Our guy was in 2000 twice, once as a baby and once as an adult. He was in 2030 twice also, but again, we can't represent it properly in 2 dimensions.

So, by now you are asking yourself why in the hell am I torturing my brain over this. It's easy. Lots of people believe that time travel is impossible. I don't believe that. I think it will be horribly difficult but I think it's possible. I think one of the important things is to not think about why a thing is impossible, but how you could accomplish it or circumvent the restrictions. I have come to believe that nothing is impossible. Improbable maybe, but not impossible. I have been trying to not worry about things that are impossible, but rather to think about how they could be accomplished.
