I did do some searching on this site for an answer to this, but couldn't find exactly what I was looking for. So, here it goes:(adsbygoogle = window.adsbygoogle || []).push({});

First -- assume that the gravitational field that Jim experiences is "homogenous" (that is, constant magnitude and direction within his region of spacetime).

Jim is standing on the Earth and is holding a clock. Bill, who has a similar clock, is in a rocket ship that is accelerating at a constant 1g (as measured by the body weight scale that Bill is standing on).

1 - Since, according to Einstein, these two cases are "equivalent", then shouldn't Jim's and Bill's clocks remain synchronized forever?

If this is true, then what this website says about relative aging is misleading.

It seems, rather, that a clock in an inertial frame of reference, for example a clock on a satellite, would age differently than Jim's and Bill's clocks.

2 - In this case the satellite is in 0g and Bill and Jim are at 1g, then after 5 years have elapsed on Bill's and Jim's clocks the satellite's clock will have aged 83.7 years, correct?

Thanks for any insight into this.
