How deep in a gravity well are you planning to keep this cesium stopwatch?
- Elucalidavah 2y agoExactly at the point of Null Island at the epoch, of course. Or, in practice, as close an approximation as can be calculated by now.
- defrost 2y agoFun reference, although in that spirit it appears that Null Island at mean sea level for that point might be as much as 22m vertical separation from true 1G Geoid. https://en.wikipedia.org/wiki/Geoid#/media/File:Geoid_undulation_10k_scale.jpg https://en.wikipedia.org/wiki/Geoid#/media/File:Geoid_undula... Approximations are pretty easy until you get into the details, dammit.
