Why does the universe always move toward disorder?

What is entropy? - Jeff Phillips · 5:20 · Video: TED-Ed · Watch at the source

In short: From melting ice to leaking tires, certain physical processes only move in one direction. This video explores entropy, the fundamental concept in chemistry and physics that dictates the irreversible flow of our world.

Entropy is the principle that explains why things naturally transition from order to disorder. It provides the underlying reason for common occurrences, such as cream spreading in coffee or air escaping a punctured tire.

While notoriously difficult to conceptualize, understanding entropy is essential for grasping why physical processes are unidirectional rather than reversible.
