Description
Everything in the Universe rotates. Expanding this principle to the Universe as a whole may seem like a natural step, yet the idea remains unexplored and is mostly dismissed as a curiosity. Recently, however, interest in this topic has gained traction, notably due to the work of Szigeti et el. (2025). In the era of precision cosmology, addressing the growing tensions within the currently accepted concordance model has become a priority, making the study of such new frontiers increasingly relevant. While a theoretical framework for a rotating Universe is already present, corresponding computer simulations are still virtually absent. Here, we present a numerical scheme for conducting and analyzing fully three-dimensional N-body simulations of a rotating Universe, implemented within the Stereographically Projected Cosmological Simulations (StePS) simulation code. We further compare results obtained using both spherical and cylindrical geometries.
