Also I have watched many of Robert’s interviews. It is evident that he understands a great deal. Thanks to both of you from a little old lady in Indiana.

Sadly, Sean is not good at explaining things if you're in that middle range where you understand equations but lack a formal education in advance physics. He doesn't know how to get those ideas across. It's as if he's forgotten how his mind worked when he was at that stage. His book _Spacetime and Geometry_ is terrible in that regard.

Just 20 years ago, that would have seemed unimaginable. What will little old ladies in Indiana being doing 20 years from now?

Haha, I love that. "No one in the visible universe could buy your book." This actually makes me want to buy it more. I did sit through his biggest ideas lecture series through the pandemic. I have a strong math background but less exposure to physics, and I appreciated that he didn't avoid mathematical reasoning when explaining topics. I've followed Sean for a long time, initially because he was impressive in science discussions online, but I've grown to really appreciate his considerations on other topics like democracy and ethics as well. Easily my most respected public intellectual. Thanks for having him on.

one my favorite things about Sean is whenever someone asks if something really IS such and such way, he always rephrases and says "it's a useful way of thinking about it." cautiously avoiding the arrogance of saying there's anything we know about the universe that is absolutely objectively certain for any possible species at any possible time to be fundamental with no underlying phenomena. all additional data confirmed by experiment is only getting closer and closer to truth (had to go for the pun) without ever absolutely arriving there. spoken like a true scientist!

Good on Sean Carroll for including equations in his book. I think the real reason why most scientists don't include equations in their popular books is because they're actually too lazy or unable to explain the math in a manner that is comprehensible to an educated but non-expertised lay public. The result is that for the educated individual who wants more than a very superficial understanding of the math, it remains inaccessible unless they get their hands on or delve into a textbook. However, a truly talented teacher can find ways to teach the math on a more intuitive level for a wider audience

Kudos to both Robert and Sean. Not convinced though that the reason for the observed arrow of time has anything to do with low entropy at the big bang (past hypothesis). Time is a succession of changes or events (before events to after events). Even if the entropy decreases from before configuration to after configuration the time will still flow from before to after. As per some theories, the big bang was a chance fluctuation to a low entropy bottleneck - the big bang. However, time was still flowing in "before" to "after" direction on the other side of the big bang event (julian barbour's tgeory of Janus point). That IS the definition of the direction of arrow of time. It may be true that in our universe it happened that way, but low entropy is not the cause of the direction of arrow of time. In other words it just may be that in our universe the entropy of the whole universe seems to increase as the time progresses. But corollary may not be true. Also if at the big bang if everything was at one point i.e. not many degrees of freedom, then entropy can only be low. Thoughts?

Maybe entropy was very low at the initial appearance of the universe due to its diminutive size?? Disorder is only possible with several elements in an ensemble?? I’d say that disorder starts to be possible at four points, at three all configurations are still pretty much a picture of order?? So, as the universe appeared it could only ordered, as it expanded individual nodes began which made disorder possible?? If you had a tiny kernel universe that was pure energy would that be a picture of order or disorder?? I’d say it would still be a picture of order cause you can consider the tiny kernel of energy as a single unit, and as it kept expanding the number of particles appeared and started ordering themselves into systems of particles but that may still be a picture of order albeit many such ordered tiny systems of particles and as large agglomerations of particles formed then variations between those small units began to be evident and variation order kept increasing because the particles and systems of particles would form as systems according to certain relations determined by the physical laws and constants?? But it may be like a bell curve, order increasing and reaching a peak then beginning to tend towards disorder as the maximum order in terms of individual systems small and large reach a peak?? We are not beyond the highest amplitude of possible order and it’s began its downwards trend towards disorder!! So the curve starts at nothing then peaks in terms of order then slides down to increasing disorder and eventually settles back to nothing if what the conformal cosmology says is true and the evolution of our universe would eventually end in a state conformal to its beginning as a state of nothing??
