I love you keep doing this. Every podcaster should. (Looking at you, Joe and Seann).

[@godblessamerica793]

42:43 Many worlds (Duality: wave vs particle): History is acquired information = observation / The future = predictions / unknown. Therefore, wave functions can be considered History (factual) and particles (fictional and /or non fictional) can be considered the Future. However, the unknown may be considered either knowing reality of one's environment (yes or no answer), or not knowing reality (confusion/ chaos), which may be due to deception or not having enough acquired knowledge from one's experiences, I think...

This podcast is an absolute game changer for education. Casual yet informationally dense conversations with people who can nonchalantly drop high Qs for those of us with low Q's.

It's reminiscent of the 19th century literature that had a wonderful focus on comprehensibility versus crippling esoteric jargon of most journals I read today. Спасибо большое Лекс

[@fredtaylor9792]

I barely graduated high-school but I've been fascinated and following Sean Carroll for over a decade. Our school system is broken.

[@cypherpleb]

Broken with respect to the individual, yes, but not in the eyes of the state who design it, and who's needs it serves. It creates the strata they think the economy requires. Restricting critical thinking is fundamental to the slavers maintaining control. This is controlled, by design and it transcends all socioeconomic groups. It's how you get a professional class full of people clever enough to do the work but still can't see or think clearly. When you operate a war economy in service of an oligarchy, and the PR, lies and faux theatre of democracy is how you get away with it. Then it would be existentially risky for the slavers to teach the majority to see through the lie that controls them and keeps them being useful.

Well he can want that in one hand and poo in the other and see which he notices is full first. And the false data collected will unfortunately negate the initial statement of desire from coming to pass. But ignorance is bliss. He should have just said, "I hate people who believe in God."

We've been used to people conducting interviews in a theatrical way, fine tuning their voice intonation to fit a narrative or fake amazement. He doesn't do that. So he stands out and appears bored and, to some who cannot do without this theatrical trickery, boring. We've been bulls**ted into thinking that the salad requires vinaigrette to be tasteful (which, in the case of a real salad, let's face it, is the case 😁). I find it a much more honest way of interviewing. No need for a cheap veneer if you're truly interested: it'll show in the questions you ask and the dialogue that ensues. I, however, cannot listen to Mr. Friedman at speed 1x. I play all interviews at 1.5x.

[@TheOneHiraethProject]

I recently finished the softcover of Sean Carroll's book "Something Deeply Hidden," a title that has become my reference encyclopedia for those things quantum. I rarely comment on videos but had to tell you how striking your intro was when at 0:24 you said, "Listening to Sean... reminds me of Bob Ross teaching the world how to paint." What an astutely creative metaphor. I smiled when I heard it feeling the perfection in such expression. "Yes," Sean Carroll's every man way of making theoretical physics relatable IS Bob Ross-esk, and it was your brush strokes painted upon the canvas of introduction that crafted for your audience the consummate picture of who Sean Carrol is and the gift he brings those willing to suspend disbelief.

[@MrSteveramsey]

Coming from a highschool dropout who can boast of nothing but a somewhat curious mind...First time I was introduced to this theory by Mr. Carroll I had really no idea why he was saying. When I had little moments of "understanding" pop into my mind they would pop back out as soon as I tried to dwell on them. Like a wave of understanding collapsing into just words when I would try to step back and observe them. But I was determined...not to fully understand everything he's saying, but to understand why he believed something that seemed so utterly bizarre to me. Why Sean, why? I can happily say that after dozens of hours of interviews and talks and reading his book Something Deeply Hidden, I get it! Not that I totally understand quantum physics (Who does lol?) but I can see why he so strongly believes this interpretation of it. This is the first chat I've listened to since I finished the book and now I feel a sorta superposition of understanding this. When I try to measure my level of understanding I may find I think I do, then I don't, sometimes neither of those but usually a bit of both. Great interview Lex!

Sean Carroll is a national treasure. Great communicator and so knowledgeable. Recommend the Mindscape and AMA podcast. And loved how he countered the notion that human beings lack the capacity to truly understand reality and the natural world. I don’t think humanity is as ‘limited’ as some believe (especially those enamored with the idea that machines and AI systems are vastly ‘superior’ to the lowly human) so Carroll’s perspective was refreshing. “So of all the worries that keep me awake at night the human mind’s inability to rationally comprehend the world is low on the list.”-Sean Carroll

[@kristinawhite1139]

I love Sean , his restraint from wondering into the mystical is amazing. One time way before I ever stated listening to Quantium Physics I had a revelation that since everything has its opposite it accord to me that everything thing is happening in ever possible way with out beginning to no end. Like an exponential multiplication it fans out in all directions growing exponentially faster and faster. I come to the understanding that there are many me’s but the view I see is a predetermined view based on my choices. So this explains why free will and determinism have equally good argument ha ha everything has an opposite that is equally true. + - are equal in there validity and good and bad connotation is to be taken out of this. So picture one molecule of h2o in a river it has a movie camera on it and this represents me. I start my journey with all possibilities open to me and as i go i find it harder and hard to cross the whole river. I can effect my position only so much based on prior decisions. Going from poor to rich would be an example of crossing the river. I can easily start making more money with effort that might get me close to the middle but getting all the way to the other side takes some doing. Sean its not an accident its not mathematically possible to be an accident. When you speak truth you and the universe as a whole “the bigger picture” become entangled. It is and it isn’t both are true they both have to be true or none of this works.

[@kristinawhite1139]

Sean Carroll is one of the most (if not the most) scientifically and philosophically thoughtful and articulate thinkers that I am aware of. And Lex isn't afraid to appear unknowledgeable in posing touchy-feely questions, which is very effective in eliciting answers that bring confusing concepts down to the level of non-physicists. Not that Sean needs special elicitation to speak understandably, and notwithstanding the Lex's common-folk line of questioning, it is clear that he has researched the subject area of his interviewee and understands the landscape and the landmarks.

Your work as a musician can be a doorway into the understanding of how performance operates according to a kind of field dynamics and the rules of probability. It's the perfect time to integrate your body-knowledge!

[@Davemon1957]

One of a few jaw-dropping moments in my life, one listening to this podcast two listening to Alison krauss sing

[@dajandroid]

I would do anything to have had Sean as my college physics teacher. Thanks for this effort of getting Professor Carroll’s public-relatable understanding(s) (certainly a subset of his universe) of today’s physics captured. I love the FOMO to infinity and beyond, reference. Isn’t that the motivation for all research efforts? The FOM understanding (FOMU). I wonder if Sean thinks about the branching into many universes as providing the entropic driving force for the arrow of time by increasing the degrees of freedom. Some of those increased degrees of freedom are lost in access by being branched into other worlds.

[@gaznawiali]

I think Sean's comment about training our intuition is a little bit like learning languages. When you first start learning a new language you have to translate each word. The process is slow and difficult. But over time you become so good at it that you manage to think and dream in that new language. Maybe our intuitions work in a similar way.

So first of all I actually went and checked Bob Ross, and heck was it worth it. Thanks, I'll be back soon for the conversation with Sean :)

[@PippyPappyPatterson]

Wow Sean explains multiple ideas here that I’ve had explained many times before that never sunk in until he described them here. Thank you both for this episode

[@Jamie-Russell-CME]

absolutely fantastic! The way atomic understanding came to realization. Firstly in the data of chemists, best understood in quantity comparison of material through observation and logic.

[@shadowmoon5445]

Fascinating glad I just found this channel recently.

5:24 "Sean then realized all that ever was and all that will ever be."

[@twstdelf]

"...how are we supposed to feel about that?" lol, awesome. ;) Great podcast.

[@imonaflatearthur2917]

Great comedic value here . Like accelerating while remaining perfectly still .

[@eklim2034]

Sean's propensity to put every difficult physic problem into layman term. Lex's interests in other fields' especially their somewhat relevancies to AI.

[@veridicusmaximus6010]

The setting of this interview needs to be more comfortable. It's like Sean is giving a statement to a KGB agent.

[@bean5618]

He records this is MIT. But I agree, Lex is awesome he just needs to have a more visually enticing lol

[@bean5618]

Luxemberg Green screen of the Matrix would be more fitting lol

An uncomfortable mind is a questioning mind.

[@rodneyhatch56]

Austere neatness as a vat for untidy minds.

[@scottbravo3]

This is a great comment because you’re completely right haha

[@johnholland6958]

Sean is probably my favorite guest over several podcasts. Hope to see even more of his enthusiasm despite his relative pessimism

[@korras21]

This is becoming a legend the more I listen to it.

[@FitzpatrickSD]

Best line..."Sooo....how many worlds are there" hahahah
