We find that the equation of causality provides very good results on physics. That is our first endeavour and success in describing a quantitative expression of the law of causality. Hence, our theoretical point suggests ideas to build other laws including the law of the Universe's evolution.18 pages, 4 figuresGeneral PhysicsThe Equation of Causalitytext
