Think about this. When you exercise, you are moving faster. That means that while you are exercising, time slows down for you compared to when you are sitting dormant. If time slows down, that means you should age less. This is why exercising is good. Just a thought.
So this is confusing me. According to the theory of relativity, if someone is traveling faster than me, time is slower for them than for me and, therefore, they are in my past. Even if it is a negligible difference in time, it is still a difference and they are in my past. But there's something that cannot be explained...which is the fact that I can still talk to the person when they are in my past. For example, if someone is riding a bicycle in my driveway and I am sitting on the porch, then they are in my past because they are traveling faster than me, yet I can still talk to the person while they are riding the bike. Therefore, they are NOT in a different time period than me. We are both in each other's present. Am I right about this view or not? It's very confusing
Let's analyze this a little more. Let's assume for a second that we are both in the same time period. The guy on the bike and myself on the porch... If time is going slower for them than for me, then the next second that passes by, they will be in my past and I will be in their future and we should not be able to talk to each other ... but we can continue to talk to each other... What I'm trying to say is that you can try to say that time slows down the faster you travel, but that leads to a paradoxical failure.

Recently I've been watching a lot of science shows and reading a lot of science books. I really like Physics of the Impossible by Michio Kaku. He is so good at making science understandable.
Anyway, I've been thinking about the theory of relativity recently which basically states that as you approach the speed of light, time keeps moving slower and slower for you...
So, if you traveled at the speed of light to a distant star that is one light year away and then came back to earth, 2 years would have gone by for you ... but everyone on earth would be much older. This is because people on earth would have traveled much slower than you and time would have gone by faster for them. (i.e. more time would have elapsed for the people on earth than for you). Anyway, if we can learn how to travel super fast like this, we would be able to travel into the future, which is pretty amazing.
But after thinking about this some more, I realized something profound....that none of us actually exist at the same time! This is because all objects (including people) are traveling at different speeds and are, therefore, in different locations of space-time. I mean, is it possible for 2 objects to have the same exact properties? The same height, length and width? The same weight? And be in the same exact kind of environment subject to the same exact elements? And also travel at the same speed? I don't think so...
And so this puzzles me. How are we even able to communicate with one another?
I am sitting on the porch. My neighbor next door is out in his yard running after his dog. He is in my past (because he is traveling faster than me) and I am in his future, but if I yell hello to him, he will hear me. How is that possible?
