direction of time
The direction of time refers to the way events naturally progress from the past to the future, creating a sense of sequence or flow. This asymmetry is rooted in the second law of thermodynamics, which states that disorder or entropy tends to increase over time. In practical terms, this means we remember the past, not the future, and cause precedes effect. Although physics laws are mostly reversible, the universe’s overall tendency toward increasing entropy gives time a clear ‘forward’ direction, shaping our experience of history and future possibilities.
