Do you wonder why you get emotional each time you see a certain movie, or how on earth video games are designed? Then you've come to the right place. Each week, Sean Carroll will host conversations with some of the most interesting thinkers in the world. From neuroscientists and engineers to authors and television producers, Sean and his guests talk about the biggest ideas in science, philosophy, culture and much more.","last_synced_at":"2026-07-21T04:17:06.610110+00:00","page_url":"https://stenobird.com/podcast/sean-carroll-s-mindscape-science-society-philosophy-culture-arts-and-ideas-444522"},"episode":{"title":"358 | Solo: Vacuum Energy and the Cosmological Constant","slug":"358-solo-vacuum-energy-and-the-cosmological-constant","published_at":"2026-06-22T06:48:00+00:00","page_url":"https://stenobird.com/podcast/sean-carroll-s-mindscape-science-society-philosophy-culture-arts-and-ideas-444522/358-solo-vacuum-energy-and-the-cosmological-constant","show_page_url":"https://stenobird.com/podcast/sean-carroll-s-mindscape-science-society-philosophy-culture-arts-and-ideas-444522","url":"https://www.preposterousuniverse.com/podcast/2026/06/22/358-solo-vacuum-energy-and-the-cosmological-constant/","audio_url":"https://dts.podtrac.com/redirect.mp3/pscrb.fm/rss/p/traffic.libsyn.com/secure/1d1ac211-8392-45fe-82db-99fa7f77076e/solo-DE-1.mp3?dest-id=5264190","summary":"The most surprising discovery in fundamental physics during my career as a scientist was undoubtedly the acceleration of the universe , announced in 1998. The most straightforward explanation for these observations is a positive cosmological constant, or vacuum energy. I talk about the origin of the idea with Einstein, how quantum physicists started to think about it and understand the \"cosmological constant problem,\" as well as how its discovery also raised the \"coincidence problem.\" This is the first of two connected solo episodes; the next will be on theories of dark energy that are not the cosmological constant.
