n this work, it is proposed wide and all-times Theory. A theory that analyses and encloses everything. Term Everything is defined as whole World without any remainder in any sense. In the center of Theory it was Comprehension allocated and such comprehension is defined as set of rules that one entity dispose. The Entity is defined as any observed phenomenon. Rule is global and unchangeable regulation. The Definition of Global Comprehensive Theory: 1. There are global existing rules that exist always and everywhere, 2. General (main) rule is Comprehension, 3. There exist hierarchically lower inter-dependant Comprehensions. The Comprehension is introduced as absolute criteria of the entity classification. Teleological aim of any entity is the most probable cognition/comprehension i.e. of everything. Whereas we study all, there are no random situations. The random occurrence is defined as the activity of presently unknown entities. The dynamic systems are analyzed in the same way as static. Time as a parameter is necessary ''only'' for the purpose of registering the advancement / retrogression of the entity on the comprehensive scale. Apart from the main validity of comprehension in the work, there have been found three more comprehension levels inside, and by means of theory – Cybernetics and the Theory of Chaos were described. Furthermore, it was shown, with the help of theory, how can be scientific and professional articles defined. The appliance and the expansion of the theory are shown with two examples. In the first example the classical mass-spring-damper system with step input is analyzed. All variables which describe the behavior of the mass-spring-damper system are reduced to three non-orthogonal factors: Damping, Speed and Amplitude. Furthermore, there are isolated 3 non-orthogonal bipolar types (clusters) of the mass-spring-damper system described as: Pole object inner energy – Mass (derivational) control – Spring (proportional) control. Pole transition – Hard transition and Soft transition (the mode of transition from Spring to Mass control) Pole accumulated energy – Little system energy and Big system energy With this, the link with the 2nd level of theory is established and it is identified that Energy within the system represents Persistence, Transition is represented by Maneuverability, and Accumulated energy by Educational function. In the second example, there is an equivalent to the types in the most classical manner which is defined as a behavioral type in dynamic sense. Reasons for which it is suggested to abandon the concept object regulation + regulator are shown. Extremes of the comprehensive approach as analyzing object / entity by independent excitations on one side, and object / entity as servo-system on the other side are defined. In dynamic sense comprehension of an entity is recognized as linear combinations of mode shapes. It was obtained a general type (form) of behavior which is identified with the purpose of entity / object. As a measure of (dynamic) efficiency of designed entity / object it is suggested by the designer completely independent comprehensive efficiency level of operation (ηsp). It is defined as ratio of really expressed entity comprehensions and its all possible comprehensions.
