- If something orbits earth at a fast enough speed for an appreciable relativistic effect, would information it receives from earth (like radio communication) be shifted to be faster or slower?
Relativistic motion and time dilation has been of interest to me for a long time, and whilst I am asking this for realism in writing a piece of fiction, I am curious as to how this interaction would work.
Let's say there's a large dyson ring built around earth, which is spun up such that the ring approaches the speed of light relative to the surface of earth, and so experiences time dilation. I am familiar (though confused) with the concept that two objects moving past each other would each perceive the other to be experiencing time slower than themselves (I may have garbled this and will welcome correction!) but the main effect I'm using here is the "people getting off the ISS are 0.01s younger than if they stayed", but ramped up. I am thinking "people who stay on the ring for 5 years only age 1 year" sort of thing. For now, ignore all the centipetal forces which would rip them to sludge!
My question is this: If the ring were picking up radio signals from earth, would they be received at 5x the speed (EG a live broadcast which lasts 5 minutes, would it take 1 minute on the ring?). Similarly, if the ring sent radio signals to earth, would they be received at 1/5 the speed they were sent?
My goal is to accurately(ish) explain remotely controlling something on earth from the ring, so needing information to pass in both directions. I assume that this will be limited by the slowest direction, EG if you are typing on a computer remotely from the ring, you would have a 5x lag on anything you do?
Anything you can offer to help me understand it gratefully received!
