Charge Quantisation

Electric charge is quantised because torus knot winding numbers are integers. The Hopf charge maps the U(1) winding number of the fibre S¹ to the observed electric charge quantum.

A standard mystery in physics is why charge is quantised. In standard physics, it is treated as an empirical fact or follows from Dirac's monopole argument—which requires magnetic monopoles that haven't been found.

In the CPT framework, the explanation is topological. Electric charge corresponds to the Hopf winding number. It must be an integer because only integer windings are topologically stable on the fibre.

The Hopf charge formula

The seat is the winding in the Hopf fibre. That names the integer slot; it does not mint the value of . Fractional labels on sub-knot configurations are packaging, not a quark-charge derivation.

Because topology is conserved, charge is conserved. A topologically stable knot can only be created or destroyed in pairs with its mirror image.

Classical electron radius

The winding can be expressed as for around the Hopf fibre.

This concept is established and rigorously mathematically verified within the CPT framework.
