Time Travel

A topic that still interests me is time travel. I guess to some people this might seem boring and impossible, but to me I think about the possibilities of time travel and it is mind- blowing. People have thought about this before and there are many different theories about time travel ranging from moving so fast that we actually go back in time, to time being a continuos loop, where we can pick where we want to go. I guess the real reason I want to continue researching this is just because of the  possibilities that could come out of it, and hopefully in my studies I will come across a time machine on ebay. Think of all the good that would do.
