What is Time?

Oct 4, 2026 · 14m

Summary

This episode explores the nature of time, contrasting its linear, macroscopic flow with its ambiguous behavior at the quantum level. The narrator explains how entropy and the Second Law of Thermodynamics create the "arrow of time," making the past distinct from the future. While current physics breaks down at the Big Bang, the discussion suggests that quantum fluctuations could potentially reverse entropy, challenging our understanding of the universe's origin. The episode concludes by highlighting the need for a theory of everything to unite quantum mechanics and general relativity.
