On the Arrow of Time and Organized Complexity in the Universe

This paper presents a new hypothesis on a macro law in the universe, the law of increasing complexity, to formulate the assumption that the universe we observe and the biosphere on Earth are getting more diverse and complex with time. This formulation utilizes a quantitative definition of the complexity of organized matters, organized complexity (OC) [6]. We then apply this law to the coincidence (or fine-tuning) problem about the fundamental physical constants. We introduce a new principle, the principle of increasing complexity, on the law of increasing complexity and explain the coincidence with this new principle without using the anthropic principle. The principle implies that an (approximate) reduction of this macro law to fundamental physical laws would lead to a concrete analysis of the coincidence problem of fundamental physical constants.
