A Unified Cosmic Model Based on 11-Dimensional Nested Projection

This paper proposes a cosmological unified model based on "dimensional projection." Its core innovation lies in redefining the black hole singularity as the origin of dimensional unfolding (dimension zero) and constructing an 11-dimensional nested projection structure that expands layer by layer outward from the zero-dimensional singularity. The model posits that every point of three-dimensional space is a projection of a higher-dimensional entity onto a lower dimension; dark matter is the gravitational projection of four-dimensional and higher-dimensional matter into three dimensions; dark energy is the residue of higher-dimensional energy permeating into three dimensions; quantum entanglement is in essence the multiple projection of a single higher-dimensional entity into three-dimensional space; and the weakness of gravity is the result of higher-dimensional gravity leaking into lower-dimensional space. The model integrates the 11-dimensional framework of string theory / M-theory with the holographic principle, seeking to provide a unified explanation for such core problems of modern physics as the nature of dark matter and dark energy, the hierarchy problem of gravity, quantum nonlocality, the cosmological constant problem, wave-particle duality, vacuum fluctuations, and wormhole mechanisms. Although current three-dimensional observational means impose limitations, the model achieves a logically self-consistent closed loop, offers a novel geometric perspective for understanding the nature of the universe, and can be indirectly tested through experimental avenues such as missing-energy signals at the Large Hadron Collider, short-distance gravity-deviation measurements, and high-dimensional attenuation of gravitational waves.
