Hafele-Keating experiment
Would the Hafele-Keating experiment be of any help?
Hafele—Keating experiment - Wikipedia
It involves acceleration by Earth's gravity and airplanes moving at constant speed (after accelerating of course).

1 G is 1 G
So if the spacecraft accelerated at 1 G both there and back while the other twin was on Earth also experiencing 1 G then they should be the same age? Their clocks should tick at the same speed relative to each other?
Edited by Taq, : No reason given.

Re: 1 G is 1 G
No. Gravitational time dilation is related to differences in potential of the gravitational field and not to the magnitude of the acceleration. For example, in a uniform gravitational field there would be no time dilation experienced based on changing position in the gravitational field.
I knew I was wrong, I was just curious WHY I was wrong, so thanks for the correction.
