[time-nuts] Re: gravity fields affect time keeping?

[Jean-Louis Oneto]

Hi, The short answer is that that's not the clocks which are affected by the gravity but rather the intrinsic properties of space-time. The long answer would be a course on General Relativity and I'm not able to do it. If I remember correctly, the order of magnitude for the change of gravity related to a difference of altitude between 0 and 1000m (on Earth) was of a few ns/day. Hope that's help, Jean-Louis OnetoEnvoyé de mon mobile LG------ Message d'origine------De: Kevin Rowett via time-nuts Date: mar. 31 janv. 2023 13:59À: time-nuts at lists.febo.com;Cc: Kevin Rowett;Objet :[time-nuts] gravity fields affect time keeping?From an article about moon time keeping:https://www.nature.com/articles/d41586-023-00185-z 

The author says


“...Clocks on Earth and the Moon naturally tick at different speeds, because of the differing gravitational fields of the two bodies. …”

I’m curious about what type of clocks are affected by local gravity, and how much.

Anyone familiar enough to go into
 detail?
