Part 8/11:
The relationship between entropy and time comes into focus when one considers the statistical nature of entropy — it tends to increase as there are simply more ways for microstates to arrange themselves in the future than in the past. This connection inspired physicist Arthur Eddington to propose that the increase of entropy drives the forward momentum of time.
This notion is complex, however, as it stands in contrast to various local phenomena where entropy decreases but time does not reverse. In moderate conditions—like cooling food in a refrigerator—entropy decreases, yet the continuity of time remains unchanged.
