If you imagine the Large Hadron Collider as a compactor of points, then those points will be like pool balls all surrounding a single ball, and you will get averages of 6 points colliding, and so particles will come in 6's. Gravity creates particles in real time with an outflow of magnetism, it is all physics from points where gravity has to escape, and it has 6 exits around a single point in 2D, and 12 exits around a point in 3D. Either way you are in the realm of 6's. The way that these 6's stack creates fractals.
The 6 pointed hexagon structure aims gravity towards a single point which has the origin of a previous set of gravity collisions with magnetic outflows.
Those physics build the brain too so a phase transition, and a crystal structure all start off as gravity collisions which are the same as kissing numbers created by spherical stacking. The brain being built from those fundamental physics prefers music that matches that structure. In the end that is the same as the mathematics in the link.
