Here’s a question.
We all know that if a man gets into a space ship and travels away from earth at a significant fraction of the speed of light C when he returns many more years will have passed on Earth than he experienced on his space ship.
What if you parked an eternal man in a spaceship, strapped on massive propulsion units to the Earth, and blasted it away at a significant fraction of C. When the Earth returns, will the inhabitant of the space shop have experienced many more years then the inhabitants of the rocketing Earth?
What is it? Majority rules?
Only if the space shop became a barber shop.
I appreciate the dilemma of your argument. I suppose one would have to take into account whether or not we take the freeway, and whether or not it’s regular or premium. Oh, and if we’ll have more than one driver.
Time dilation occurs as a result of acceleration, so the “eternal man” would be much older compared to the accelerated Earth.
Earth rules.
Up is relative to the fiduciary observer.
