COMMENT LAST MODIFIED, 2-27-14 at 8:53AM PST:
JeffreyH, I agree. I ask what is real, not what each person on/off the space ship (or plant/animal in the forest) perceived.
lightarrow/anyone, I understand that different perspectives will result in different perceptions of the same speed events. I ask what is real with regard to time, given that you agree that the clock in the space ship should read the same time as the clock that never moved when the space ship returns and the clocks are next to each other again. Note that I am asking what the clocks are actually displaying, not what any person's perception on earth is perceiving. That is one of my future considerations in this discussion. So, my question stands: if the clock on the space ship does not actually slow down (regardless of perception), are the claims that clocks that have traveled in space have slowed down false and that both the person in the space ship and the person who has remained on earth be the same age? Are there any other claims of empirical evidence demonstrating time is not a constant in reality (not perception)?
