The Cosmological Constant as a Synchronization Artifact:

We show that the cosmological constant $\Lambda$ is not a fundamental parameter but an artifact of fitting an exponential redshift model with the $\Lambda$CDM parametrization. In a framework where cosmic expansion is governed by the Kuramoto synchronization parameter $eta = 1 - K_c/K = 1 - 1/[2\sin(\pi/5)]$, the apparent dark energy
