366 | Jim Al-Khalili on Time, Quantum, Biology, and Cosmology

Everyone lives through time, but we continue to struggle to fully understand it. We remain unsure whether time is fundamental or emergent, why it has an arrow pointing from past to future, and how that arrow connects to our experience of time's passage. Jim Al-Khalili's new book is On Time: The Physics that Makes the Universe Tick. We discuss what time is at the most basic level, and how it connects to open questions in biology, cosmology, and quantum mechanics.
