Ireversibilitatea fizicii şi cosmologia / Irreversibility in physics and cosmology

Abstract

      The problem of irreversibility has been studied by philosophers and scientists. This paper explores the origins of thermodynamics and opposition reversible-irreversible. The structure of complex system is fundamentally determinate by the irreversibility. With helps to the cosmology ,we hope to describe the structure of our universe. Thus the black holes is very important objects in cosmology, because the cosmologists hopes to get an explanation about the structure and origin of our universe.  Here the irreversibility brings a new view about the lost information in the black holes. This view depends to the topology of space-time.

        Thus the concept of irreversibility has many significations and reveal other and other difficulties of the universe view.
