Calculations (3:141 - 56) based on Whitehead's theory (2:303) showed that the orientation of the two masses relative to the center of the galaxy should produce a variation in the attraction between the two masses, and hence in the
gravimeter's
readings: as the earth rotates, bringing the earth,
gravimeter, and galaxy center alternately into and then out of line, Whitehead's theory predicts that the attraction should likewise vary periodically, with period 12 hours (i.e., the galaxy center,
gravimeter, and earth are in line twice a day.)
