Observer-Centered Formalism (OCF) is an approach to Physics that puts the observation in the center of the formulation of the laws of physics; OCF is concerned of only "what The Observer can see" and describes the world "as it's seen by the observer". In stronger terms OCF postulates that it makes no sense describing the physical reality that is not the subject of the observation, t.e. what is not being observed doesn't exist. OCF is an extension of Copenhagen Interpretation of Quantum Mechanics and it paints a less deterministic picture of the universe. OCF introduces a mathematical object Я describing the Observer and suggests that the laws of physics must explicitly include Я. The observable laws are therefore different for different observers and different branches of Physics might become asymptotic idealisations corresponding to Я-functions that are orthogonal, and thus can not be observed simultaneously. OCF outlines a different approach to developing a Theory of Everything by suggesting that Quantum Mechanics, Quantum Electrodynamics and General Relativity are all orthogonal and therefore can not be observed simultaneously. OCF makes causality violations impossible and thus resolves The predestination Paradox OCF explains why the Space and Time are treated differently in Quantum Mechanics. OCF eliminates assymetry between the future and the past [] and provides a logical proof for the 2nd Law of Thermodynamics.
