A quick question for those fast with the GR and SR math. Assume you get in a spaceship and start accelerating away from Earth, and during the trip you and the people left behind compare clock speeds periodically (not elapsed time, but rather tick rates). At what combination of acceleration and speeds would the GR effects from acceleration (which tend to make the clocks on the Earth look faster to you) be more significant than the SR effects from speed (which would tend to make the clocks on Earth look slower to you)? Assuming I'm wording this problem clearly. Is this only dependent on acceleration (i.e., for a given high enough acceleration, the GR effects will always dominate), or for most accelerations, will there be a speed you eventually reach where the SR effects catch up and pass the GR effects? I would generally assume the later given a constant acceleration, since the SR effects grow, but don't the GR effects also grow with distance? Anyway, I would appreciate a precise math relationship between the two if someone could whip one up for me (with a qualitative explanation also of course). Thanks much.
