The entropy gap and the time asymmetry

Mostrar todas las versiones(2)

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...
