well, if they have the same speed compared to the same thing they will never become older compared to each other. they have the same flow of time. if they dont have the same speed or are compared to different thing one will have a slower flow of time and will be younger when they reach the same speed to compared to the same thing
:lecture: zelos :lecture:
Everything has the same speed with respect to
something.
You can cross reference every atom in the universe and find that every one can be said to moving at the same relative speed to some point somewhere. Then that point can be calculated to be moving at the same speed as another point, relative to yet another point. The whole lot would eventually cancel out in such a way that time dilation isn't possible under any circumstsnces.
That would make the whole of relativity superfluous and completely pointless.
My point is that from each of my two observer's frames of reference, they are the one who is going to die first while the other one stays young.
Let's just assume that there is a method of instantaneous communication over infinite distances, wormhole, subspace, whatever. Distance and speed should be completely irrelevent if the two observers are able to carry on a video conference with each other all the time.
In this case then each observer would see the other remain young while he himself aged.
It doesn't make sense.
