Hubble tension, together with results from the Dark Energy Spectroscopic Instrument showing time-dependence of dark energy, indicate that the standard model of the universe is inadequate, and the list of unsolved problems in cosmology and physics is uncomfortably long. Here I introduce a theoretical description of a simple geometric model that offers intuitive solutions to these problems and a broad range of unexplained natural phenomena. The Time-Partition Model of the Cosmos is based upon the assumption that the initial singularity was spinning at high angular velocity prior to the Big Bang, resulting in extremely high angular momentum. Big-Bang expansion converts angular momentum into Universal Helical Momentum (UHM), the fifth fundamental force, and dark energy is revealed as a fictitious centrifugal force that we perceive in our spiraling, non-inertial frame of reference. The model conforms to known physical laws, unites the fundamental forces as either centripetal or centrifugal forces of helical motion, and reveals the physical reality of dark energy, dark matter, zero-point energy, and time. UHM acting together with the force of gravitational attraction is the kinetic force that drives matter into helices and continuously higher levels of complexity at every scale, and as such, is the counterbalance to Brownian motion and entropy.
