Welcome to the August 2022 Ask Me Anything episode of Mindscape! These monthly excursions are funded by Patreon supporters (who are also the ones asking the questions). We take questions asked by Patreons, whittle them down to a more manageable number - based primarily on whether I have anything interesting to say about them, not whether the questions themselves are good - and sometimes group them together if they are about a similar topic.

Finally.
How many intellectual persons give away 3 hours of their own life once per month to share their wisdom? Yes, I know there are universities. But for us who have passed that many years ago, it’s a relief. Go Sean. Never look back. Go Sean. Thank you.
Not to take away from it but we are paying him by listening. Sean made it pretty clear in the early going that part of doing these pod casts was to make money. I enjoy them as well and he certainly isn't obligated to do the pod casts but he's not giving it away. Keep up to good work though. I think it's a great medium and Sean deserves to be compensated for his time
@@themeach011 I am not sure if it would happen without the subscribers , but those of us who cannot afford to subscribe are very grateful that both Prof Carroll and the people who subscribe put the effort in and reward that effort , given the bollocks that is on the internet , these islands of knowledge are a sanctuary in a sea of shite . Once again thanks to you all .
It's great to here your voice sir, hope your all well, thank you for this , great

Did you just say "That is to say..."?
You are now officially a philosopher.
I like when Sean says "whereas" in compound sentences, and I've gotten to sometimes using it more often in speech and writing, whereas I probably would not have done that, had I not become a Mindscape podcast fan.
Just wanted to shout out the high quality transcripts on the website... I lost my place and was able to find it right away by using the timestamps you have there.
Thanks Sean! Great episode with lots to think about.
Cool! Didn't know you had a podcast too. I always look forward to new podcasts with you at lex or Joe etc so it's very nice to discover you have your own!! Big fan! And now I see there's years of previous material 😃 Lovely!
What we need is a new “key” to open up that next layer of physics. Einstein had a key, Newton had a key, etc
You should look at Taylor and Wheeler's book on Black Holes. They show that as you approach (timelike) the singularity in a black hole from the time you first feel a 1g difference head to foot, you will be spaghettified to "nothing" in less time than a nerve signal can travel to your brain.
A thing to watch for tonight. Thank you! Amazing Sean Carroll.

This is the first time I have seen this wonderful series, although I have seen Sean Carroll on many other people's series. Congratulations and thanks!
Just a couple of trivia which two of the questions reminded me of.
Re. metric signatures: The science fiction writer Greg Egan wrote some novels which take place in universes with different metrics. He did an impressive job of working out the implications and effects of those metrics, although I'm sure he himself would admit that there are still many more implications he did not have the time, or possibly the knowledge, to consider.
Re. the Bayesian analysis of the data or assumptions necessary for the Bayesian analysis of the data or assumptions necessary for the Bayesian analysis of ... This reminds me of Lewis Carroll's dialogue between Achilles and the Tortoise.
I always understood that the spaghettification was caused by the stretching of space-time and as a result you would not notice it as it’s the Space warping not you.
Now I do agree that you would be stretched. but do you feel the stretching of gravity waves?
Roombas might not break your fingers, but they will terrify your cats.
Love these, cheers as always Sean ☘️
it will move when we do, just as social media mutes words.
22:25 This is one of the very few ( if not the only one!) times - apart from strictly technical talks/ discussions- where , in a video that is intended mainly for the general public the distinction between "space-like" and "time-like" singularities has been made.
And this distinction is important for the understanding of how the interior geometry of black holes "works".
Usually, pop sci videos on YT ( many of them, unfortunately made by professionals : astrophysicists, particle physicists etc) give the impression that typical Schwarzschild black hole singularities are " pointlike objects with infinite density" which is of course totally wrong...
The only slight objection with prof. Carroll 's explanation is when he compares White holes with the Big Bang:
It is true that both initial singularities are spacelike, but there's an important difference, that white holes are highly anisotropic ( the Weyl curvature diverges in the beginning) while typical FLRW cosmologies are isotropic ( conformally flat).
Please grant us timestamps, I sometimes think about the topic, but keep listening, because I'm usually cooking, then don't know where in video to look
I'm not defending James Webb by any means and I'm sure I'll get absolutely roasted even though I'm a strong supporter of the LGBTQ2+ community but I think it's not completely fair to judge people of the past by today's standards or laws rather than the laws of the day. Obviously by today's standards these things are all despicable and looking back in history there have been unending examples of behaviors that are not acceptable by today's standards, but we have to remember the world was a very different place in the past and the laws of the day or what was deemed acceptable was much different than how we all live today. Like I said I'm not defending Webb and I don't like his name on the telescope. He may have been a total creep but one day people of the future will look back at us and judge us by our actions and possibly be totally disgusted by things we do that are perfectly acceptable to us and follow the laws and customs of the day. I actually think one day our culture and the way we live will be looked back on very harshly by the people of the future and they will shake their heads at us just as we shake our heads about the people of the past and how they lived and acted.
I understand where you're coming from. But there are lots of scientists the telescope could've been named after. Webb was the head of NASA during the 1960s when they were gearing up for the moon landings. That doesn't really correlate to astronomy or astrophysics.
Very insightful, humane and generous response to the issue of protest against anti-abortion advocate. I wonder if it will lose you any followers though.
Carroll's statements about sociopolitical issues in general are wonderful examples of the humanist ideal of being a good person, furthered by the kind of logical reasoning a well educated intellectual should use.
Statistical speaking, schools in urban areas tend to have more resources pumped into them ; unfortunately the environment for learning is less conducive
The problem I have with an only physics explanation of physical reality is that it does not include an important aspect of the picture: Biology. The universe is "alive". [If you doubt that, I would ask, are you alive? You are universe.] How is that explained by physics and what significance do they give to that in trying to explain what they see?
If our universe is living, it was born. If it was born, it has parents which it resembles. Thus, using biology, on the premise that the universe is living, we can surmise that our universe is a function of the interaction between other pre-existing universes like our own, and from whom we got our "laws, mass, and including our life, intelligence, creativity, and consciousness, all of which are only associated with living things. At that point, our living universe would exist in a common time and space with those other universes (or what's left of them), and including a myriad of other related "living universes" like stars in a night sky. Essentially that is the realm beyond the boundary of our expanding universe. When we can see that far, they will appear much more that 14 billion light years away. Our universe would be effected gravitationally by those large bodies of mass, like the other galaxies that effect our Milky Way, so that would offer another explanation for the gravity that we measure holding our universe together that we currently theorize is associated with a super high density dark matter...
You wrote in The Big Picture: “If the particles and forces of the Core Theory are what constitute each living being, without any immaterial soul, then the information that makes up “you” is contained in the arrangement of atoms that makes up your body, including your brain. There is no place for that information to go, or any way for it to be preserved, outside your body. There are no particles or fields that could store it and take it away”
Doesn’t that sentence seem a bit absurd when the information about “you” is contained in your genome and passed on to any offspring you may have, among other emissions from your body?
Bag of worms my new favorite saying
The Sting! 🙂👍
The correlation with free will as its limitations, even if it was established that quantum mechanics escape causality somehow, it doesn't mean the brain does. One can not choose an option he/she isn't aware of, for instance, you can't postulate free will exists simply because causality breakdown at the quantum level, your will doesn't manifest itself through the wave function.
Why would a person in an important job, like a politician, remain in their position when most people hate what they do. Does one need to be psychotic's to do so?
They are psychotic is more explained in the term of the people that are in command of those in position and do nothing about it and say nothing in town square has been eliminated to adjudge and political Revenue Service from costumed enforcement with belt of death and armory quadruple ammunition anybody would need clubs, tasers & drone mentality OF willfully internet on persons's civil interest and squads of other team members willing to interact and remove freedoms from the people that govern them Salary
help me out I agree do you think the same
Peace? 👽 No peaccceee....😱
We are missing a complete understanding of time. Every explanation I have ever
heard of about time travel ( minus "Back to the Future" ) leaves out electrical
charge from the equations related to time. There are just 4 properties of the
physical universe: Mass, Distance, Time, and Charge.
Velocity is a Distance over Time
( V = D / T ).
Energy is Mass multiplied by Velocity squared
( E = 0.5 * M * V ^ 2 ).
Force is Mass multiplied by Acceleration
( F = M * A ).
Acceleration is a Distance over Time squared
( A = D / T ^ 2 ).
The Force of Gravity is the Gravitational Constant multiplied by 2 Masses over
their Distance apart squared
( F = G * M1 * M2 / D ^ 2 ).
The Electromotive Force is the Electromotive Constant multiplied by 2 Charges
over their Distance apart squared
( F = K * Q1 * Q2 / D ^ 2 ).
What if we use the last 2 and set them equal to each other?
We would have the components ( M, D, and Q ) in one equation;
( G * M1 * M2 / D ^ 2 = K * Q1 * Q2 / D ^ 2 ).
but it would also turn into a unit-less ratio.
So, multiply by Einstein's Energy...
( E = ( G * c ^ 2 / K ) * M3 * M2 * M1 / Q2 / Q1 / ( 1 - V ^ 2 / c ^ 2 ) ^ 0.5 ).
by ( V = D / T ) we get...
( T = D / c / ( 1 - (( G * c ^ 2 / K ) * M3 * M2 * M1 / Q2 / Q1 / E ) ^ 2 ) ^ 0.5 ).
If I have not broken any rules of algebra and the physical laws I have used are true,
this should be a valid physical law as well... Time is most commonly imaginary
( square root of a negative number ) making the universe understandable for
living systems by keeping cause and effect in order. On the subatomic scale,
we have the charge-mass relationships ( +/- 1/3 or +/- 2/3 ).
For Quantum Entanglement M1Q1 and M2Q2 become entangled until M3 ( Einstein )
observers them.
What if Dark Matter is just quantum entangled mass?
And Dark Energy is just Lazy Light ( a slight red shift that doesn't become noticeable
until the light has aged millions or billions of years ). "Entropy"
Would the world be better off if we were to try to move from survival of the fittest, to survival of the species?
I agree with your comment you're quite pessimistic spectacle my friend. ¿ฯ¡ Do you have fun!
@@rolandovazquez9246 I do enjoy watching all the nut jobs. When I return and submit my report, they will find it very difficult to believe.

I have a question for you. Since Schrödinger wave function is a non-physically realizable time independent equation, how can one use a time unlimited no bandwidth wave-equation to extract any viable information of our universe? Attached a link for your reference: th-cam.com/video/PiBxdhA03pM/w-d-xo.html
Well the Schrodinger equation is really describing a probability wave, and reality is really an argument about what probability is.
OMG! Sean Carroll literally has the same favorite books as me. Pride and prejudice and The moon is a harsh mistress. Maybe I should've gone into theoretical physics. :D

Only in your reference frame though.
Hehe. 👍
