Is this always true? So GPS is precise to the nanosecond, but inaccurate by a quarter minute?



The earth is slowing down its RPM.



Too much friction. When that happens, you should lubricate the

bushings on your globe. If that's insufficient, replace them with air

bearings, which should help decrease the rate of slowing.


A magnetic bearing would be great, but that would require the earth have a magnetic field.

Oh wait..............
