Big Bang: The Possibility of a Cyclic Universe
Year: 2026
Type: article
Abstract: This paper proposes a self-consistent cyclic universe model, arguing that the Big Bang is not the absolute origin of the universe but a transitional node in an infinite closed evolutionary cycle. The universe operates under a dual critical threshold mechanism: it expands continuously until approaching an upper cosmic scale limit, then reverses to a contracting phase; when it shrinks to a lower quantum-scale critical threshold, accumulated extreme energy triggers a new Big Bang, restarting cosmic expansion. The paper analyzes the theoretical rationality and physical plausibility of this model, showing that the cyclic universe hypothesis is scientifically reasonable and provides a new perspective to address the limitations of the standard Big Bang theory.
