Why Non-Linear Source Geometry Does Not Imply Superluminal Signaling: A TCGS-SEQUENTION Response to Gisin-Polchinski

The Gisin-Polchinski (GP) no-go theorem (1990–1991) is widely cited as proof that non-linear modifications to quantum mechanics necessarily permit superluminal signaling, thereby violating special relativity. This note demonstrates that the GP argument relies on ontological assumptions that do not hold within the Timeless Counterspace & Shadow Gravity (TCGS) framework. Specifically, GP assumes: (i) time is ontically fundamental, (ii) Alice’s measurement “causes” a change in Bob’s state, and (iii) the density matrix is the complete description of physical reality. In TCGS, where observable 3D reality is a projection of a static 4D counterspace, the apparent “signaling” dissolves as a foliation artifact. Non-linearity at the source level is fully compatible with operational no-signaling at the shadow level.
