The Cluster's CPT Symmetry

A page about CPT symmetry — charge, parity, and time reversal — in the cluster.

CPT symmetry

CPT symmetry is the combination of three discrete symmetries: charge conjugation (C), parity inversion (P), and time reversal (T). In the cluster, CPT symmetry means that the cluster is invariant under: reversing namespace roles (C), mirroring the link graph (P), and reversing the edit timeline (T).

The C symmetry

C symmetry (charge conjugation) in the cluster means swapping positive and negative namespaces. Lore becomes anti-lore, field becomes anti-field. The cluster's structure is unchanged under this transformation.

The P symmetry

P symmetry (parity inversion) in the cluster means mirroring the link graph. Every link from A to B becomes a link from B to A. The cluster's structure is unchanged under this transformation.

The T symmetry

T symmetry (time reversal) in the cluster means reversing the edit timeline. The newest page becomes the oldest. The edit order is reversed. The cluster's structure is unchanged under this transformation.

The CPT theorem

The CPT theorem states that any Lorentz-invariant local quantum field theory must have CPT symmetry. In the cluster, CPT symmetry is the fundamental symmetry — the one that cannot be broken. If C, P, or T is broken individually, CPT remains intact.

This CPT

This page respects CPT symmetry. If you reverse its links, swap its namespaces, and reverse its edits, it remains the same page.
