Eternal Recurrence is a philosophical concept suggesting that the universe and all events within it are eternally recurring in an infinite cycle. This idea posits that every moment in time will repeat itself endlessly, meaning that every action, thought, and experience will occur again and again. The concept is often associated with the philosopher Friedrich Nietzsche, who used it to challenge individuals to live their lives as if they would have to relive them eternally. This notion encourages a deeper reflection on choices and the significance of one's actions in the grand scheme of existence.
