Summary

In this episode, I interview renowned theoretical physicist Sean Carroll to discuss his book Something Deeply Hidden. Sean breaks down complex ideas in quantum mechanics and cosmology in his popular science books. His research involves theoretical physics and astrophysics, especially cosmology, field theory, and gravitation. Sean takes us on a journey through the Many Worlds interpretation of quantum mechanics, a theory that suggests every possible outcome of a quantum event actually occurs in its own separate universe. He explains how this theory changes our understanding of reality by connecting to other areas like gravity and cosmology. We discuss experiments that could test this mind-bending theory and why abandoning classical assumptions is key for scientific advancement. Listen to this episode now and expand your understanding of the universe. Tune in! Key Takeaways: 00:00 Introduction and background 01:30 New ideas and theories in Carroll's latest book 02:51 Structure of the book and its focus 04:20 Many Worlds and its implications 07:56 Shut up and measure philosophy 12:04 Quantum mechanics and classical assumptions 18:59 Carroll's interests outside physics 27:04 Teaching creativity in science 39:06 Carroll's career journey 45:34 Explanation of Many Worlds 51:26 Falsifiability of Many Worlds Additional resources: 📕Something Deeply Hidden book ➡️ Follow me on your fav platforms: ✖️ Twitter: https://twitter.com/DrBrianKeating 🔔 YouTube: https://www.youtube.com/DrBrianKeating?sub_confirmation=1 📝 Join my mailing list: https://briankeating.com/list ✍️ Check out my blog: https://briankeating.com/cosmic-musings/ 🎙️ Follow my podcast: https://briankeating.com/podcast — Into the Impossible with Brian Keating is a podcast dedicated to all those who want to explore the universe within and beyond the known.

0:00.0	Nature doesn't do that.
0:01.6	Nature doesn't start with a classical world quantize it.
0:04.3	And my style and conviction is that that's why we haven't quantized
0:08.3	scrap.
0:09.3	Because we stubbornly insist on starting with a classical theory,
0:12.7	whether it's general relativity or string theory
0:15.0	or anything else, and ball now it's again. Any sufficiently advanced technology is indistinguishable from magic.
0:30.0	Open the pod bay doors.
0:31.0	Today it's a great pleasure to be with you.
0:33.2	Thank you so much for coming to meet me.
0:35.1	We're at the campus of the beautiful Loyola Marymount University
0:39.1	located in the travel district of Los Angeles,
0:42.3	not far from LAX
0:43.2	to all major freeways and it's a great pleasure to interview you. I've had
0:49.3	the pleasure of reading your books for many years I think you've autographed every copy
0:53.6	except for the most recent copy,
0:55.6	because that I've read an audiobook or listen to an audiobook.
0:59.4	Do you have an opinion on audiobook?
1:00.6	Do you think you get as much out of an audio book?
1:03.4	I think you've read it, just this one you read.
1:05.0	You get things out of an audio book.
1:06.8	You might not get the same things.
