Assuming we could understand all the laws of physics and understand all forces that exist in our universe, does the universe have a definite path? Could we theoretically calculate the result of all the properties of the universe to determine exactly how everything in the universe would behave? The first variable that would arise that can't be explained by any physics would be life. The universe and all matter and energy had a definite and determinable path until life became. Actions taken by life are completely unpredictable by any physics. The universe and all matter had a definite path until life came about. Is this true? What other unexplainable variables in the behavior of matter and energy could possibly exist?
