We are in approximately the same area of space-time; otherwise, we wouldn't be able to interact. I'd say I'm about where you are, give or take a second or so. Based on relativity, the maximum difference between our times is the time light would take to travel from me to you, which isn't long at all.

This post is not on page 15. You should know this forum doesn't distort our perception like that. And the post I just quoted most certainly exists.[/b]
I know, I was just throwing out numbers

The difference between our times - that makes sense. But how would that apply to person traveling near the speed of light who witnesses only 10 years pass by, while I witness 20 years pass by, and yet we still end up in the same time frame?

I know Einstein's T=T/sqrt(1-(v/c)^2))... but why does this work? How did he prove this? Does time just become independent for every observer - like there is the universal time, that we pretty much usually experience, and then there is the internal time, separate of the universal time, which is dependent on how fast you are moving? Maybe all time frames already exist?

I don't know see how traveling faster than someone has any affect on how long it takes their light to reach my eyes. I'm not sure this principle applies anymore for larger speeds. (doppler shifts do not apply because you can either see something speed up or slow down depending on which direction you'd be moving)
