Why the proton has three loops

Scattering electrons off protons, first at SLAC in 1968, revealed three point-like constituents inside the proton. Physics calls them quarks. In RSI they are the three loops of the proton's braid, and no quark has ever been seen alone because a loop drawn out of the braid loses the shared density shadow that holds it.

Why three? Physical space has three independent axes of rotation. A braid with one loop turning about each axis fills every rotational degree of freedom that space allows. These are the paper's six axes of resistance: three toroidal rotations and three poloidal ones. With fewer loops, one axis is left unbalanced and the braid wobbles. A fourth loop would have to share an axis with another and would clash.

The three loops press against each other under the Universal Mechanical Clamp, and their three points of contact form a triangle. A triangle is the one polygon that cannot change shape without changing the length of a side, which makes it the most stable arrangement for three bodies pressed together. That rigidity is what holds the braid in one piece. The loops mesh at those points of contact, where their density shadows overlap. RSI calls this region the Shadow Junction; it is what particle physics calls the gluon.
