No. 2: Time’s Arrow

Time is intangible but stubbornly persistent. We move forward, inevitably and relentlessly. We can’t grab a moment in time. We can’t point to it once it’s gone. Is time real or an illusion? Will we ever defy the arrow of time, stop its flow or go backwards? Astrophysicist and writer Janna Levin invites Physicist/Philosopher David Albert in conversation with science writer James Gleick to consider the possibilities from Time Travel to Time’s Arrow.
