And this is how God is? In your scenario, the year is 2025. I left in 2005. When I get back, I feel as if I havent been gone more than a couple hours.That means I must not have aged in those 20 years I'm gone. So I look the same, feel the same as when I left. Everyone else is looking and feeling older. This is science fiction. Watching too much Star Trek I say. Anyway, You make the contention that God is on earth as I am gone and He is also with me as I am floating in space those 20 years. The point is it is still 2024 as I make my way back. In space and on earth.There are no two time frames.
Ok to get upto speed you need to read some SR (special relativity),GR (general relativity), time dilation theory, Lorentz math. Use Justchristian's link which I mentioned a few posts back. Its easier enough to understand and stays away from the serious math behind the theory but it does explain it nicely. Read about 'muons', '4 atomic clock experiment', 'time dilation', 'twin paradox' specifically.
2024 is defined as how many times the earth has gone around the sun. How long does that take using a stopwatch....it depends on your time frame. You may see it as so many seconds but I would record it as something else if I were to record it at speed. Sound confusing, well it is, but science has long accepted this.
