The traditional formulation of the ultimate goal of physics (in the narrower sense of axiomatic theory) involves the derivation of physical laws from first principles. Though, such option doesn't make things easier since the task of the first principles finding is not less complicated versus to the original problem. The alternative path for understanding the world around us is to interpret the fundamental limit values as a factor determining the physical laws structure. A significant part of this path has already been completed. It was possible to show that the quantum mechanics can be built on the basis of the existence of the minimum quantum action, while the special theory of relativity - on the maximum speed c. Furthermore, from rather recently it became clear that a similar approach could be implemented in general relativity but in this case it can be constructed by postulating the existence of a minimum lengths. The goal of this review is to demonstrate the effectiveness of limit values as a tool for describing the physics of the Planck scale. Moreover, by virtue of their universality, the limit values allow us to establish relationships between, on first glance, distant fields of physics. We will consider the simplest consequences of the inclusion of gravitational effects in quantum reality. The most important consequence of this consideration is the inevitability of transition from the classical concept of continuum to the concept of the discrete space-time. The new physics generated by such transition will be in the center of our attention.
