The Planck Legacy recent release revealed the presence of an enhanced lensing amplitude in the cosmic microwave background (CMB), which is higher than that estimated by the lambda cold dark matter model (ΛCDM). This endorses a closed and positively curved early Universe with a confidence level greater than 99%. In this study, quantised spacetime worldlines are utilised to model the evolution of the Universe in reference to the scale factor of the early Universe and its radius of curvature. The worldlines revealed both positive and negative solutions, implying that matter and antimatter of the early Universe plasma evolved in opposite directions away from each other as distinct sides of the Universe during a first decelerating phase. The worldlines then showed a second accelerated phase in reversed directions, where both sides could be free-falling towards each other under gravitational acceleration. Simulations of the spacetime continuum flux through its travel along predicted worldlines demonstrated the fast-orbital speed of stars resulting from external fields exerted on galaxies via the spatial curvature through the imaginary time dimension. Finally, the worldlines predicted a final time-reversal phase of rapid spatial contraction leading to a Big Crunch, signalling a cyclic Universe. These findings indicate that antimatter could exist as a distinct side, which influences the universe evolution; physically explaining the effects attributed to dark matter and dark energy.
