[time-nuts] gravity, space and time

[Chuck Harris]

I guess I am not getting it...

Using relativistic effects on time to sense gravitational changes
is like using dynamite to clean barnacles off of a boat... you can
do it, but surely there is a better tool?

A large part of the dithering about of precision analytical scales
is due to gravity fluctuation caused by the all manner of things.
You can see the fluctuations without going anywhere near 1E-16 in
time, or anything else.
