TOWARDS THE PROBLEM OF OBSERVABILITY IN GRAVITATION AND COSMOLOGY
The question whether the Univers as an whole object is observable is decided as that of metaphysics but not that of phenomenology. The role of Zelmanov's chronometric invariants in the overcoming of the positive methodology in general relativity is shown. However, Zelmanov's paradoxe about the relativity of the Univers infinity is a challenge to all the geometric paradigm in the theoretical physics.
