Ah, "never touch, bump, etc." implies that the effect of changing the orientation of gravity is not reversible.
Or is it that returning to the original orientation undoes the 10E9 effect but leaves a 10E12 permanent change? I'd like to do the experiment myself, but I'm still getting rid of stuff to get room on the bench.

This gravitational acceleration effect is rather huge, parts in ten to the 9th or so, and anyone can see this. This is why you never touch, bump, or move, or rotate a laboratory frequency standard (this includes GPSDO and cesium standards). _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
