| Résumé : | A cosmological model is proposed in which an inflationary de Sitter spacetime appears as the result of a fluctuation in the conformal degree of freedom of an initial Minkowski vacuum. A population of black holes is thereby created, which evaporate during the inflationary phase. Then a second phase transition turns the de Sitter cosmology into the usual Robertson-Walker universe. The temperature and specific entropy per baryon of the present universe are deduced, and depend only on the mass of the black holes and on the universal constants h, c and k. © 1987 Nature Publishing Group. |
