The Arrow of Time and Entropy
This chapter delves into the philosophical question of why the past is different from the future and the concept of entropy. It explains how the increase in disorder and chaos, as described by the second law of thermodynamics, gives rise to the arrow of time. The chapter also explores the idea that the universe can be eternal but gradually empties out, with new universes coming into existence through quantum fluctuations.
