The entropy gap and the time asymmetry

The universe time asymmetry is essentially produced by its low-entropy unstable initial state. Using quantitative arguments P. Davies2 has demonstrated that the universe expansion may produce a decreasing of entropy and, therefore, this fact explains its low-entropy states. This idea is implemented...

520 3 |a The universe time asymmetry is essentially produced by its low-entropy unstable initial state. Using quantitative arguments P. Davies2 has demonstrated that the universe expansion may produce a decreasing of entropy and, therefore, this fact explains its low-entropy states. This idea is implemented in a qualitative way in a simple homogeneous model. A rough coincidence with observational data is found.  |l eng
