The Supermassive Podcast episode on the Multiverse which inspired this video: https://audioboom.com/posts/8420475-do-we-live-in-a-multiverse
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.

👩🏽💻 I'm Dr. Becky Smethurst, an astrophysicist at the University of Oxford (Christ Church). I love making videos about science with an unnatural level of enthusiasm. I like to focus on how we know things, not just what we know. And especially, the things we still don't know. If you've ever wondered about something in space and couldn't find an answer online - you can ask me! My day job is to do research into how supermassive black holes can affect the galaxies that they live in. In particular, I look at whether the energy output from the disk of material orbiting around a growing supermassive black hole can stop a galaxy from forming stars.
