In the movie "Tenet," the concept of "reversing entropy" plays a significant role. Entropy, in the context of thermodynamics, refers to the measure of disorder or randomness in a system. The second law of thermodynamics states that the entropy of an isolated system tends to increase over time, leading to an overall increase in disorder.
However, in the world of "Tenet," there is a technology or phenomenon that allows the reversal of entropy on a localized scale. This means that certain objects or individuals can have their entropy inverted, causing them to move backward through time. In the movie, this is referred to as "inversion."
By reversing entropy, objects or people can experience time moving backward from their perspective. They can perform actions that appear to defy the usual flow of time, such as catching objects that were dropped in the future or moving backward in a way that seems to defy physics.
The concept of reversing entropy in "Tenet" is a fictional interpretation of time manipulation, where the normal arrow of time is reversed for specific entities or objects. It creates a unique narrative and visual spectacle within the movie's storyline.
