Abstract
The universe time asymmetry is essentially produced by its low-entropy
unstable initial state. Using quantitative arguments P. Davies(2) has
demonstrated that the universe expansion may produce a decreasing of
entropy and, therefore, this fact explains its low-entropy states. Thi
s idea is implemented in a qualitative way in a simple homogeneous mod
el. A rough coincidence with observational data is found.
