Resume:

Among participants gathered at Les Treilles from 4 to 9 July, 1988, fifteen were physicists analyzing the different theoretical options that emerge from the new conceptual landscape offered by the cosmology at that time (see below the detailed list of participants and their interventions) .

During the few years preceding the meeting, understanding the evolution of the structure of the universe and was deeply upset. A new cosmological paradigm has indeed emerged: “inflationary cosmology”, resulting from the unexpected union between theory which manages the world of the infinitely small, that of elementary particles, and one that describes the infinitely large, the universe as a whole. The extraordinary fact is that this inflation simultaneously solves all the conceptual problems which were absolutely insoluble as part of the traditional theory of the big bang called the “standard model”.
