ABSTRACT
Memento is a psychological thriller about a man who misperceives his personal time through recurring short-term memory loss. Besides compressing distances, wormholes that connect black holes also skew time. That becomes an emotional story element as the time distortions allow a lead character to appear as a “ghost” to his young daughter in a different temporal era. The loss grows as the system functions, and so the direction of the increase in entropy defines the way to the future. Entropy has been given the poetic name “the arrow of time” because of this one-way property of systems. Tenet struck many as long on running time and confusion and short on making emotional connections with its viewers. Yet, as Richard Feynman once brilliantly expressed, humanity has its own built-in time arrow that carries feeling.
