The paper discusses a possible expansion of modern physics to include physics of Life since all attempts to create livings from non-living matter failed. Prior to the discussion, a life/non-life criterion is proposed: unlike physical systems, Livings can move from disorder to order without an external interference if the model of life concentrates upon the concept of intelligent behavior and does not include such “auxiliary” processes as metabolism and reproduction. A mathematical formalism suggests that a hypothetical “particle of life” (L-particle) can be represented by a quantum-classical hybrid in which the force following from the quantum potential is replaced by the information force. Besides the capability to move against the second law of thermodynamics, L-particle acquires such properties like self-image, self-awareness, self- supervision, est. that are typical for Livings. However since the L-particle being a quantum-classical hybrid acquires non-Newtonian and non-quantum properties, it does not belong to the physics matter as we know it: the modern physics should be complemented with the concept of the information force that represents a bridge between non-living and living matter. It has been suggested that quantum mechanics and mechanics of livings are sub-classes of a broader physical model, and the difference between them is due to different Liouville feedbacks, i.e. in different information forces. At this stage, L-particle is introduced as an abstract mathematical concept that is satisfied only to mathematical rules and assumptions, and its physical representation is still an open problem.
