Re: Neat
"Speed of movement (General Relativity) has been tested this way since the late 60's but the actual force of gravity itself is new."
Is it? Time dilation due to variation in gravity has been demonstrated experimentally many times over the last 50 years ... Did they not send an atomic clock to the ISS (or as a Shuttle experiment) to do a weightless comparison some years ago?
If this system is much more sensitive to that variation that may be new, not the experimental concept itself.
