Hexagontum physics!
The dense gravity wave trejectory is based apon the mass location in degrees from the Earths axis; This is why you have mass/pyramid/volcanos say at 10° latitude matching mass 180° and at the same latitude.
In otherwords mass (A) is at 21° latitude from mass (B) located at 21° latitude, the trejectory is based on the degree angle relationship from mass (A) to the Earths axis.
