How is this situation resolved, assuming no FTL?

But unless the rate of acceleration was enormous it would’ve had to start when the spaceships were very far apart to reach 86.6% of the speed of light before the spaceships passed each other and before the clocks on the spaceship said two hours had elapsed. And if they were that far apart then the preceding argument would still be relevant.* *But If the acceleration WAS enormous, then new and complicated things start to happen. For example, if you’re undergoing very high acceleration (or alternatively if you're in a very strong gravitational field) and you look at somebody’s clock that is undergoing less acceleration than you (or in a weaker gravitational field) then you will observe that their clock is running FASTER than your clock not slower.* * John K Clark See what's on my new list at Extropolis <https://groups.google.com/g/extropolis>* xtm poe > > -- You received this message because you are subscribed to the Google Groups "Everything List" group.
