Causality: The Nature of Everything

We pursue research leading towards the nature of causality in the universe. We establish the equation of the universe's evolution from the universe-state function and its series expansion, in which causes and effects connect together to construct a linked chain of causality. And the equation of causality [1] is rederived. Therefrom, our theory informs the progress of the universe and, simulaneously, a law that presents everywhere. Furthermore, we lay some foundations for a new mathematical phrasing of the movement of physics. That is the life-like mathematics - a mathematics full of life.
