Based on the core premise that "ether = energy", this paper proposes the central hypothesis that consciousness is a high-level form of etheric motion, systematically explaining the essential connection between consciousness and physical reality. The study argues that consciousness is not an inherent cosmic property but a product of the universe expanding to a specific stage. High-level etheric motion (consciousness) follows exclusive laws such as logic, and there is an intersection of laws with the low-level etheric motion studied in physics. This intersection constitutes the intrinsic connection between mathematics and physics. On this basis, the paper demonstrates the negative correlation between mathematical complexity and the validity of physical theories, pointing out that simple mathematical forms are more compatible with objective physical reality, while physical theories relying on advanced mathematics (such as string theory) have an extremely high probability of being incorrect. Finally, it discusses the issue of the independent existence of consciousness separate from living organisms, providing a new theoretical perspective for the study of the nature of consciousness and cosmic laws.
