Title: The Price of Abandoning Dark Matter Is Nonlocality
Link: https://arxiv.org/abs/2402.11716v1
Description: We consider the classic question posed by Pardo and Spergel about the price of abandoning dark matter in the context of an invariant, metric-based theory of gravity. Our answer is that the price is nonlocality. This has been known for some time in the context of the quasi-static regime. We show that it also applies to cosmology and we exhibit a model that reproduces standard CDM successes such as perturbations in the cosmic microwave background, baryon acoustic oscillations, and structure formation.
