He managed to get someone to do the measurements:
Domus Vista Gravity Project
The results were that the gravimeters measured the gravity quite well (with a standard deviation of 0.008 mGal). There is no mention of Bjarne's theory. There is no mention of a variation from the predictions of Newtonianian gravity.
Of course Bjarne is now claiming in
another thread that the experiment will not work due to "Data are too inaccurate. It's too much noise and too many unknown factors that play a role, and the building is simply to light, compared to the gravitational noise etc."
He now wants to build a 5m by 5m cylinder weighing 98,125 kg to do the test.
