The recent Planck Legacy (PL18) release revealed the presence of an enhanced lensing amplitude in the cosmic microwave background (CMB). Notably, this amplitude is higher than that estimated by the lambda cold dark matter model (ΛCDM), which endorses a 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 with reference to the scale factor of the early Universe and its radius

... curvature. The worldlines revealed both positive and negative solutions, implying that matter and antimatter of early Universe plasma evolved in opposite directions as distinct Universe sides during a first decelerating phase, corroborating the CMB dipole anisotropy. The worldlines then indicated a second accelerated phase in reverse directions, where both sides could be free-falling towards each other under gravitational acceleration. Simulations of the spacetime continuum flux through its travel along the 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 early Universe plasma could be separated and evolved into distinct Universe sides that collectively and geometrically influencing the evolution of the Universe, physically explaining the effects attributed to dark matter and dark energy.
