This thread is still alive? Honestly this was more or less a shower thought that I figured I'd post for feedback from people more informed on the topic. Thanks to everyone for your contribution.

Yeah, I understand that. My confusion wasn't really towards how relativity works but (what seemed to me to be) a special case.

I see. I guess I just tend to overthink things. Thanks for the reply.

So, I've been thinking a little recently. I've had this idea in my head that I feel is probably wrong, but I'd like some insight into why it's wrong if that be the case. So let me explain... I understand that objects moving at very high rates of speed experience time dilation. A clock aboard a spaceship moving at a high rate of speed will tick slower than one sitting stationary on earth. So, in theory, someone who boards a hypothetical spaceship could move at a very high rate of speed over an extended period of time and exit with less time being passed on his body than what has been experienced by the outside world. Thus being time travel. However, I've been doing some thinking, and have thought of a difference between the ticking of a clock and the aging of the human body. The ticking of a clock is a scheduled event. It is predetermined to happen once every second. Thus, every second produces another tick of the second hand. The clock will tick slower for an outside observer because time is passing slower on the hypothetical ship, thus making these scheduled events more spaced out in the remote observers relative time. However, aging seems to be sort of a dynamic process. Driven by cause and effect. It is reactionary to things that happen within one's body and no event is predetermined (at least it seems) to have a certain amount of time in between it and the next event. So would this mean that perhaps relativity would not slow down the aging of the body? Or am I looking at the idea of relativity in the wrong way? I'm sure it's the latter, but if anyone could offer an explanation, that would be great. I realize a few extra problems and/or questions in regards to this. Obviously nothing would appear to be happening any slower than normal to the on-board observer. So his aging would appear to take place at the same rate as it would appear to him on earth. But if my original thought is correct, then his aging would seem to take place more rapidly since time on the craft is moving slower, at least I'd think. I felt like I'd share my thought/confusion with you all. It seems I may just not be fully grasping the concept of time. Apologies, just realized this probably should have went in the "Speculations" forum. Feel free to move it if you'd like.
