"Nothing Twice"

"Nothing Twice" is a concept from philosophy and science suggesting that, in a universe with changing conditions, it's impossible for exactly the same event or situation to recur in the same way twice. Because everything is in constant flux—particles, energy, and context—each occurrence is unique, even if it appears similar. This idea emphasizes the transient nature of reality, highlighting that perfect repetitions are virtually impossible, and that truly identical events are extraordinarily rare or theoretically nonexistent. It encourages recognition of life's continuous flow and the uniqueness of each moment.
