Cyclicity of the Universe as a Phase Transition of Elastic Vacuum: from the Principle of Multi-thread Balance to the Planck Limit of Contour Medium Deformation

This paper proposes a fundamental non-relativistic cosmological paradigm based on the concept of absolute Space-Matter and elastic physical vacuum. Based on the universal Law of Potential Distribution of Multi-thread Media, an end-to-end model of Universal Self-regulation of the Universe is derived. It is shown that self-regulation is carried out without artificial control systems and is ensured by a strictly defined two-contour geometric relationship of interacting bodies and media of Matter. Quantum Planck quantities and wave fluctuation fields are proven to be the fundamental support and bearing basis of the Universe. The evolution of the Universe is substantiated as a deterministic cyclic process of changing modes of accelerated Expansion (Multiplication of media) and instantaneous Collapse (Reduction). It is established that all parameters of Space-Matter exist in a strict range (the "corridor of limits") between the lower (Planck) and upper limits. During the expansion of the Universe, this corridor narrows due to the loss of interrelations between bodies of Matter, which, upon reaching the Planck "stop", triggers the mechanism of instantaneous cumulative collapse of Energy. The full period of the Cycle of Rebirth and Improvement of the Universe is about 3.84 × 10¹² years.
