Put simply, the universe's inception can be described as a non-equilibrium phase transition triggered by a spontaneous symmetry-breaking mechanism during the Planck epoch, where quantum fluctuations in a scalar inflation field instigated an exponential expansion through a non-perturbative vacuum-energy-driven inflationary process, setting the stage for the subsequent anisotropic distribution of dark matter and baryonic matter through multi-scale gravitational instability in the evolving cosmic lattice. Galaxies formed via complex hierarchical clustering, where primordial gas and dark matter halos accreted through turbulent magnetohydrodynamic processes, with angular momentum redistribution governed by non-linear gravitational dynamics, and central supermassive black holes, such as Sagittarius A*, emerged through the accretion of relativistic plasma and the merger of stellar-mass black holes within a relativistic fluid framework. The universe's macrostructure is shaped by a dual interplay of dark energy-induced accelerated expansion and the gravitational pull of dark matter, where galactic kinematics, exemplified by the anomalous flatness of rotation curves, necessitate the application of non-Euclidean general relativistic models, cosmological perturbation theory, and high-order dynamical friction processes, forecasting eventual galactic coalescence and the morphogenesis of elliptical remnants via complex topological transitions in spacetime.
