The dynamic quantum spectral model of the Universe with phase transitions combines quantum mechanics, field theory, and cosmology to describe the evolution of the Universe through changes in its quantum state. This model assumes that the Universe can transition from one quantum state (phase) to another under the influence of changes in energy density or other quantum characteristics. Phase space models consider a quantum system that can exist in different "phases," similar to the aggregate states of matter. For example, in Kenji Hamada's theory, space at low energies is a "rigid" but elastic continuum, while at ultra-high energies (in the trans-Planck region or at the centers of black holes), a phase transition occurs, and space becomes "background-free"—the familiar concepts of coordinates, distance, and time disappear.
