**9.5 Statistical thermodynamics and the arrow of time**

Direction of time from past to future is supported by three arguments

• **Cosmological time**

The cosmological time goes according the standard model of Universe from the Big Bang to future.

• **Psychological time**

We as human beings remember (as a rule) what was yesterday but we do not "*remember*" what will be tomorrow.

• **Thermodynamic time**

Time goes in the direction of the growth of entropy in the direction given by equation (125). The statistical thermodynamics allows due to its probabilistic nature a change of a direction of time "**from coffin to the cradle**" but again with a very, very low probability.
