Is MOND an Emergent Effective Law of a Complex Dark Matter Sector?
Abstract
In this work we aim to present a new perspective for MOND theory, namely that MOND theory is not an answer for the missing matter at galactic scales, but it provides a phenomenological description of the dynamics that DM should produce at galactic scales. We also aim to point out that MOND dynamics at galactic scales is achieved by scale-dependent self-interacting dark matter, which can behave as collisionless and collisional, depending on the scales and the physical processes. To this end, we first aim to highlight the successes of the Λ-Cold-Dark-Matter model and how it overwhelms over the MOND paradigm. Using textbook physics, we present the successes of the Λ-Cold-Dark-Matter at cosmological and cluster scales, and how these phenomena cannot be described consistently by MOND theories. Thus, by excluding MOND as being a viable description of nature at all scales, we conclude that MOND may not be the answer behind missing matter in Newtonian galactic dynamics, but it is just showing how the dynamics of dark matter should behave at galactic scales.
