Will Time Stop When The Universe Ends?

Our Spotify podcast: https://open.spotify.com/show/5rqQFYd... You have always assumed that time keeps moving on its own. Whatever happens, whatever stops, the clock keeps ticking, and surely it always will. But every clock ever built, from a swinging pendulum to an atom counting nine billion beats a second, runs only because the universe is out of balance, and one hundred trillion years from now, when the last star burns out, that balance slowly begins to fade. The direction that makes tomorrow different from yesterday is not written into the laws of physics at all; it is borrowed from a supply of order that has been draining since the Big Bang. So when the last black hole finally evaporates and the last difference in the universe levels out, is there any sense left in which time is still passing? Tonight is a slow, calm walk to the very end of the universe, and to the stranger end of time itself, through the death of the last star, the long cooling of the degenerate era, the silent reign of the black holes, and the darkness beyond. Along the way we take apart what a clock actually is, why the arrow of time may only be temporary, what physicists mean when they say time might not be fundamental at all, and why a single accidental tick might, against every expectation, return after an eternity of stillness. Get cozy and let this slow journey to the end of time keep you company tonight.
