This paper investigates the hypothesis that the expansion of the universe is influenced not solely by dark energy or inflation, but also by an inherent rotational motion. Drawing from Newtonian mechanics and general relativity, we show how a small but global angular velocity could explain certain observational discrepancies, including the Hubble tension. We derive rotational contributions to the Friedmann equations and compare them with ΛCDM predictions. Recent peer-reviewed research (2023–2025) is included to show that a slow rotation is theoretically possible and observationally permissible. Quranic references suggest an expanding and layered universe, consistent with the proposed rotational framework.
