Mindscape Ask Me Anything, Sean Carroll | April 2022

Perhaps my favorite three and a half hours of the internet month. (..though a F1 weekend runs close!)

1:30:48 re: F1 "There's a lot of physics involved. The physics involved is NOT the kind of physics where you can spherical cow your way out of complications." Wow! Such a wonderfully tight turn of phrase! Your speaking has really grown in fluidity, confidence and even erudition since I started listening to your YouTube channel shortly before BIitU. I also appreciate your pacing. Most presenters take forever to present the germ of an idea. With Sean, the ideas keep flying.

Thank you so much dr sean for this amazing podcast

Would be great to get timestamps on these questions.

After reading "Something Deeply Hidden" and listening to your podcasts, I find myself reading anything quantum physics related with your voice in my head. For example, I just got into the "Spin magnetic quantum moment" section of my physics textbook book and your voice just switched on!

Can you please interview Neil turok?

Very interesting, tahnk you. The correlation between the entropy and time is fascinating indeed.

These are a pleasure to listen to.

Cool. I live in ABQ. I had no idea you were in NM. How do you like it in the land of enchantment?

iv been watching you ever since i saw you on the history channel. i love your mind!!!

I love the variety of questions and responses in these q&a podcasts! There’s a nice mix of scientific questions with philosophy and personal ones, but all answered in a way that prioritizes reason. Very entertaining!

Thank you, Sean.

The thing I wanna ask you about. If the universe consists of two infinite 4d spaces, divided by a Planck-sized wormhole (like the center of a torus, the torus being open on the outside), could it be two 3d universes are pushed into real existence from a virtual state? Like Hawking radiation? Could all matter (except gravity) be confined to 3d while expanding in a negatively curved 4d space (the Gaussian curvature on the mouth of a torus is negative). Maybe our universe is, together with a mirror universe (antiprotons, antineutrons, positrons, and antineutrinos) expanding from a central tiny mouth, and when the both have accelerated away to infinity, the stage is set for a new inflation around the mouth, and two 3d universes are spat out, which again expand to infinity, etcetera. Is there an argument that reasons against this? Thanks in advance!

Great show, your AMA are amazing content. Thanks Mr Dr Sean

Professors: “don’t make excuses”. Also professors:

30:57 WOW, Sean isnt a Star Wars nerd ..... I'm not quite sure how to handle that!

Never mind, you answered my question in the video. Sounds like you liked your time in the land of enchantment.

Congratulations Sir 🎊 best wishes on your new post, philosophy is an amazing discipline, its very new to me but thanks to many of your Vlogs have encouraged me to to learn as much as I can.

Hello prof Sean Carroll, for a long time I have this question and I can't find the answer, In your research about "emergence" I always wonder if the in 2009 introduced theory on emergent or entropic gravity by prof Erik Verlinde of the university in Amsterdam? (Netherlands) if you find the time thank you so much. (later I found some more info and Erik Verlinde)

I'm amazed how he can speak so clearly. It's like I couldn't even write an essay better than the way he casually speaks.
