Abstract
Tracing in the historical perspective evolution of our knowledge on elementary particles and Universe we come to the fundamental relationship of cosmology and particle physics. The revolutionary change by the quantum field theory of the notion of elementary particle put on more fundamental level particle symmetry and corresponding charges, reflecting the fundamental structure of micro-world. This fundamental structure of micro-world determines the structure and evolution of the Universe. Extension of the relationship between microscopic and macroscopic descriptions to the largest and smallest physical scales leads to the fundamental relationship of micro and macro worlds, studied by cosmoparticle physics in the proper combination of physical, astrophysical and cosmological signatures. Old V.A.Fock’s ideas on physical rigor and on fundamentality of physical approximations can find interesting application in our modern approach to the foundations of cosmology and particle physics in their fundamental relationship.
