he Supermassive Podcast episode on the Multiverse which inspired this video: https://audioboom.com/posts/8420475-d…

The sci-fi TV show Rick & Morty uses the idea of a multiverse in its episodes and its a brilliant story. But in terms of the science, does it check out? Well there are two main ways of interpreting the idea of a multiverse in physics (both hypothetical and unproven), either (i) the quantum mechanics many worlds interpretation, or (ii) the bubble universes from eternal inflation. So which one does Rick & Morty explore? And how does it compare to other sci-fi shows employing the idea of a multiverse like Everything Everywhere All At Once, Spider-Man: Into the Spiderverse, Spider-Man: No Way Home, His Dark Materials, Doctor Who, Community (Remedial Chaos Theory and the darkest timeline), and Sliding Doors.
