A Structural Analysis of the Big Bang, Entropy, Arrow of Time, Black Holes, White Holes, and Quantum Fluctuations.

This paper presents the Unified Low-Entropy Cosmological Framework (ULECF), which analyzes the origin of the universe, entropy evolution, and cosmic structure formation from an integrated perspective.According to this framework, the universe may have originated in an extremely low-entropy initial state, from which the direction of time (the arrow of time) and cosmic evolution naturally emerge.The framework attempts to integrate black hole thermodynamics, gravitational entropy, quantum fluctuations, and potential white hole structures into a unified conceptual model.The objective of ULECF is to provide a coherent structure for understanding several fundamental puzzles in cosmology, including the entropy paradox and the origin of time direction.
