Entropy Quote by Sean M. Carroll
“The arrow of time doesn't move forward forever. There's a phase in the history of the universe where you go from low entropy to high entropy. But then, once you reach the locally maximum entropy you can get to, there's no more arrow of time.”
About This Quote
Source Lecture: The Nature of Time, 2015
Time’s direction is tied to entropy; after reaching maximal entropy, the arrow ceases.
In simple terms: Time moves forward because entropy rises, but stops when entropy peaks.
Key Takeaway
Understand entropy’s role in temporal direction.
