Dimensional Reduction as Source of Cosmological Anomalies

Abstract

Dimensional Reduction (DR) conjectures that the number of spacetime dimensions monotonically drops with the boost in energy scale. According to DR, the expectation is that ordinary space progressively unfolds from being one or two-dimensional near the Big-Bang singularity. This work argues that DR a) can explain some of the observed anomalies challenging the standard model of cosmology and, b) provides a platform for unifying the particle and gravitational interpretations of Dark Matter.
