COASTING BIG-BANG

We consider a cosmological model in which the early universe is domina ted by the equation of state p = -rho/3 corresponding to a coasting co smology. This equation of state was first obtained in the context of c osmic string theories whereas its one-parameter generalization describ ing a coasting early universe followed by a radiation-dominated univer se was first derived from Kaluza-Klein theories based on Euler form ac tions. We show that in such a model the temperature is almost absolute zero at the beginning and the universe quickly heats up to maximum te mperature.
