We argue that models in which an observable variation of the fine structure constant is explained by motion of a cosmic scalar field, are not stable under renormalization, and require massive fine tuning that cannot be explained by any known mechanism.

Dilaton-induced variations in Planck constant and speed of light: An alternative to Dark Energy
gr-qc 2024-12 reject novelty 4.0 of 10

The paper assigns dilaton-dependent ℏ and c in a scale-invariant fermion-gauge action, derives a τ∝l^{3/2} time scaling, and claims this replaces dark energy, with the supernova fit deferred to a companion paper.
