Welcome to the August 2023 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. Enjoy!

From the mega solo episode into this AMA. So grateful for all the content!
Never imagined I would be so captivated listening to a physics professor talking about a barbie movie
I even found myself repeating it to a friend because I found the premise desirable
ive been using wikipedia since early 2000s sean ty :)
Sean you are the epitome of honest, down to earth science. Thank you.
Yay, I love these episodes... i can't believe I'm in the first couple hundred to view it... this makes my entire week for sure... Sean Rocks!
Sean for President!
Agree about the depth of openness as requested. Thank you Mr Carroll!
Copenhagen isn't wrong, It isn't even right!
I love Sean's suss haircut.
oh yes please, 4 hour episodes are the best :D
Bookmarking this so we can revisit the UFO discussion after emergent disclosure solidifies
now that im 28 do u mind showing me what the metric tensor is? and the alcubierre metric ya know thats interesting stuff dude:)
Was not expecting a Sean Carroll analysis of the Barbie movie
crankin' 'em out right through here ❤️
Great AMA!
Thank you!
The big shock is about how did this stuff got hoisted into a thing with the government officials acquiescence and congress conducting “inquiries “!
It's done to distract people from pressing political issues/scandals. Governments all over the world have been doing it periodically. It's annoying that people still haven't gotten wise to this trick.
If particles act like a wave. Should this mean they might and up in the complete different place if measure on the very large (cosmic)distance from the source.
Do you really find the existential risk of AI to be acceptably low, or do you find the risk inevitable, and therefore not worth focusing on for the reasons you describe?
1:42:32 "I think these two questions [about course-graining] are more-or-less the same." lol 🤣
Really appreciate your answer, Sean! That was helpful.
You were great in the movie Fast Times at Ridgemont HIgh.
Sean, you made my day today with your comment on the UFO nutjob talking about the holographic principle. I had incidentally listened to it live as background noise. When he said that I almost fell off my chair LOL. Too bad there was nobody of reasonable background in that hearing who could have asked him serious questions and make him sweat a little. He clearly lives off the lack of knowledge in his audience. Not saying everyone out there needs to know about the holographic principle, but you'd hope in given setting there would be at least a few experts who could keep that guy honest and accountable.
I feel the same. Felt good to hear a bit of sanity with this madness
the nutjobs usually edit out the reasonable questions

When the camera detects the light, the photons cease to exist? How come? Someone please explain. Thank you.
Supposedly, a photon gets absorbed it emits an electron which can be detected. Yes it does cease to exist. Many things absorb or reflect light and the energy gets transferred somehow (electrical, heat etc..).
@@freehat2722 I understand now. Thanks a lot. 🥂
I don't understand where he gets the extinction risks of AI being a very tiny number. Almost no serious person I know of has that number below 5% and many are above 50%. Those numbers are not small enough to be a distraction.
Because he's not simply trying to get people's attention or be sensational or grab the spotlight with fear mongering... There's no realistic threat of extinction from AI... There's threats to extinction from nuclear Holocaust, meteor strike, or plague... But even plague causing extinction would be very low almost nil... Anyway computers aren't going to come alive and try to kill us or out compete us. Computers will never be alive and they will never try to take over.
Only realistic problem is that the infrastructure could be run by computers that we can't directly control or really understand and therefore the infrastructure could get really messed up if those computers get out of control. But that's not going to cause an extinction. It could cause problems but look at all the fear mongering around y2K and The reality of it...
Face it people are irrational fear-driven creatures who constantly miscalculate reality... Please send me $100 for the time I took to respond and enlighten you.
3:05:49 Sean’s gives what amounts to a beautiful picture of the full multiversal “life history” of one photon being emitted as a roughly spherical quantum wave in an astrophysical event. As it’s spherical wave moves outward at the speed of light anything it encounters has a chance of interacting with it resulting in one new branch of the multiverse, and within that new branch the rest of the wave disappears. But in the rest of the multiverse, the entire spherical wave continues on attenuated slightly because the probability of that one possible outcome is subtracted off.
It’s quite a different picture from a water wave in that in each branch, the wave ‘crashes into’ only one thing, so to speak, and in that branch the rest of the wave disappears. But in the rest of the multiverse, the entire only slightly attenuated spherical wave continues on. In principle, there always remains some branch of the multiverse wherein the entire, though very attenuated spherical quantum wave front continues outward forever.
Speculation:
We can detect, fairly accurately, from what direction the photon comes. Wouldn’t it be interesting if we could also measure the curvature of the quantum wave itself. Then we could not only detect the direction, but also the distance to its origin. In some cases red shift gives us this information, but wouldn’t it be cool if we could detect quantum wave curvature directly.
Where do you get the energy to keep going? Do not stop, however!
I wanna have a large language model trained with Sean Carroll sayings. And compared with the original biological langauge model
Be honest you want a Sean copy like Hari on foundation, me too.
An archaeologist here, any and all scholarly activities funded by the taxpayer should be public and available to the general public aka the people who are footing bill.
Probability is fundamental. See the proof by Wojciech Zurek (revisiting previous work by Gleason but with greater clarity). It emerges as a direct consequence of the axioms of QM: Hilbert space, Unitarity, and conservation of instantaneously repeated observations (ie pointer states evolve continuously so you measure once you get the same answer if you repeat it quickly enough). That plus Graham Schmidt is all it takes to derive the Born rule and elevate Probability to a first-class physical entity or concept.
It's the dreaded zoo hypothesis! In the far-fetched hypothetical that aliens *are* here, they're not hiding and they're not right in our faces. Hovering benignly on the periphery is apparently how we interact with animals that we're trying to domesticate... 😅
I had the idea that you can keep throwing electrons into a black hole, eventually the electrical force may overcome the gravitation force and cause the black hole to pop back out of the event horizon.
Regarding Anti Desitter Space? (And a Drunk looking for keys under a Lamppost)
Alcohol kills brain cells. You will get more alcohol going towards the parts of the brain most active; they are using more blood to process thinking, short term memory generation, and whatever brain process is 'conscious awareness' Being drunk is more than that of course but I am no expert. So being drunk will harm short term memory, reduce conscious awareness or in practical terms...ability to pay attention or NOTICE unexpected circumstances...and in general harm brain functions. If your current mind/brain is impaired you will rely on autopilot MORE far more than when you are not drunk. Autopilot exists for everyone; when you first learn to walk or ride a bike...every second your conscious mind controls each detail. Once that skill exists it is automatic, and this frees your conscious mind to focus not on balance but which direction to go and what speed and idle thoughts/short term planning that is minutes or hours ahead of time. Someone NOT drunk is more likely to remember they dropped their keys in a dark location away from lights. Someone who is drunk will be more on autopilot; the reason the joke makes sense is the autopilot reduces wisdom among other things. But someone not drunk can still use a broom to scrape the ground, or slide shoes across the ground, or swing a stick back and forth across the ground; all methods to push against a larger surface area that is dark and you cannot see...to feel or to hear your keys moving after being pushed around.
So what is a 'broom' for understanding spacetime?
No idea! I only had some irreverent stuff about drunks!
To the person who asked about probability: you will love David Deutsch's work.
These prof Carroll's long podcasts are nice! But nothing beats his books.
Holy shit, prof carroll is into watches and basketball
I fell asleep to a different video and woke up to this. Was very confused as to why Hawkeye Pierce from MASH was talking about superconductors. Sean Carroll sounds a lot like Alan Alda. But probably much more knowledgeable about superconductors.
What if dark matter was out at the edge of the expanding universe being constantly converted into space and matter as the universe continues to expand and balloon into existence?
In the beginning, Space expanded, which was the launch of the arrow of time. Gravity slows the expansion, which slows time locally and makes time relative to the position of the observer. This is what it looks like to me. Perhaps the arrow reverses direction inside the event horizon where Space is contracting? If so, then maybe black holes connect to White holes in the past?
A white hole can only exist in the epoch before the big bang. See it as the negative part of the timeline, with the big bang at T=0, where time also moves backward from our frame of reference.
@paulmichaelfreedman8334 what "epoch before the big bang"? Wouldn't that be like exhaling before you inhaled? I think the big bang itself sounds like a white hole. It's a stretchy thing for the imagination, isn't it? I think a good imagination is really important for the scientists who are trying to reveal the reality of it all.
@@Kerrsartisticgifts One of them will get it right eventually. Maybe one of them already has but is unfalsifiable until we have better measuring equipment.
Snark!❤
UAP UFO comments at 22:22
Maybe Kelly Carter from the Calgary Church of Christ would talk about zero, one and infinity. He is in canada right now.
Shouldn't the universe grow due to keep information in? At light speed everywhere. How would virtual particles fill in the gaps if they do?
Why does Sean say that superconductors at room temperature do not conflict with the rules of physics? I thought that the material needs to be very cold to slow down the vibration of atoms so that the electrons can move freely, leading to superconductivity.
Maybe a non-sciencey answer. Atomic theory doesn't provide a complete description of atoms. It's complete, in as much as atomic behavior is generally predictable, and quantum behavior isn't necessarily all within the, theory or mathematics.
We don't know precisely how electrons or particle theory, should **completely** interact with atoms. Or, field theory. Who knows, if electrons are behaving as particles or waves within LK-99.
So, my interpretation, which may not be 100% correct. Is were not sure if the phenomenon you describe, applies between electrons and the atomic, system.
So, in another way, maybe the best answer is that a field theorist will have an enormously precise description of why Lk-99 works or doesn't work. Maybe at some point it's proven precisely what you are asking about, is the reason why LK-99 works or does not. The atoms do something unique, within the system, and that's the answer.
The problem is to make superconductors at room temperatures
We don't have a value for the concept of 'very cold' in this context.
@@CorwynGC close to 0 K, to slow down the vibration of atoms
@@CorwynGC it's true I believe that "low temp" super conductors all typically require liquid nitrogen, and result at a sort of peak around, -172.
And so this is now, obsolete and still interesting. The other way of stating this is where not sure why or how a lattice supports superconductivity and equally interesting the opposite of this. So something about these macrostructures might produce states or enable or allow them.
And it's super interesting in that this appears to only be described systemically from outside of the boundaries of the object itself. Maybe it's not difficult, the real physicists can correct me, but why general atomic principles can say something about how opposing states arise, true in different materials.
So it's "reach for the sky" or "reach for something else" for properties. Confusing!!!
I'm not sure. I'm exhausting my vocabulary. It's already, exhausted! This manifold does this and this does that, and meanwhile we're not changing how atoms decay? What the hell is this? And meanwhile a freight train still blows through either of these, gloves on and you're fine? I don't even understand this.
Your last episode was fantastic. Internet can really promote outlandish concepts quickly and your podcasts help to remind people of the foundations of physics that should guide you. This is a great public service you do.
Dark matter question: With the 1st iteration, it was calculated from the difference of star movement. Since then, there are discoveries of massive halos of frozen gas engulfing galaxies and the existence of massive electromagnetic fields amongst other things. Shouldn't these have a massive, slightly or possibly explain some of dark matter?
My other issue is having prominent scientists describe gravity as a fundamental force. Shouldn't it be emergent due to Einstein's theory on spacetime known for over 100 years. They also claim how weak it is. It my be locally weak but its range seems infinite e.g: the Great Attractor pulling us. That's not infinite but that's a long way away.

How can you disagree - in the Minkowskian spirit - about the deep equality of time and distance? It's common misunderstanding that it is possible to go back and forth in real space. Matter defines spacetime (or spacetime maintain matter) and when you are moving forward then the space behind you is not the same space any more - there the defining matter has been changed - you can never go back to the past positions but when you imagine you turned back, you only turned to the direction where the next forward direction is to be found. Space and time are really equal.
Fuck those that snark. Much respect due Sean. You rock bro!!!
I have questions, but none that you can answer, so am not asking
Yeah the recent hot topics of science nearly all sound like something I would love to believe are true but that's why I am more skeptical.
i was messing around in the kitchen and i think i got it. i made the super conductor in my microwave with the descaler and the pipe cleaner.
where do i apply for my Nobel Prize?
Is the event horizon where temperature cant communicate with outside due to gravity strength? I've heard no temp but Stephen H's temp equation shows tiny temps (tinyer as you increase size!).
But is this the temp of an infinitely thin boundary called EV or is it the temp of everything inside?
If its the whole hole (😅), my level 0 physics tells me that a colder hole would "feed" off of vacuum energy (or that 2.7 kelvin leftover temp from BB).
Why is this thinking wrong?
If there are room temperature superconductors then they must be made of some exotic stuff, because we don’t see them in mineral form. The Earth has spent billions of years cooking up all sorts of element combinations in various ways - yet we’ve never seen a mineral with any of there properties…. Sorry.
They do have room temperature superconductors. They require very very high pressures to work, that's an issue.
6:51 I heard super conducting curry conductor and got excited
Yummy !
So if gravitational waves travel as fast as light in space So can one say that speed of light is actually the property of spacetime! If yes, how can we intuitively understand this property?
Secondly, light doesn't impact space, but gravitational waves do by stretching and contracting spacetime and losing energy? Yet it still continues with the same uniform speed. Please help me understand better! Thanks 😊
Gravitational radiation is two kinds: fluctuating gravitational waves which do not lose energy nearly at all - and gravitational change signals (because of ongoing alterations in matter distribution) which do affect surprisingly strong phenomena; for example occuring by lunar tidal waves; changing signals consist huge amount of energies IF they were trapped as longlife structures in galaxies and in clusters - enough to even explain the familiar 'dark matter parameter'.
Sure. If you consider something 'moving' through spacetime, you can consider that everything 'travels' at the same 'speed'. Moving faster in space means moving slower in time.
Prof. is more wedded to the definitions of speed etc., hence the quote marks.
Light DOES impact space. One could in theory construct a black hole with nothing but light. "Kugelblitz" is the term.
magicians are funny, they pull rabbits our of hats, except society feels like they want to disappear in the hat, because our sub conscious ego fears and embarrassment, but instead of fear or feeling bruised we must admit many things could go wrong, but if we calmly communicate we can move on from these outcomes and find new inspirations.
To be fair Timex used to make cheap mass produced mechanical watches as well that weren't renowned for their accuracy well before they made quartz watches.
A thought about Rogan v no-Rogan. A factor might be to assess whether the/a show is maliciously or carelessly anti-fact as apposed to merely misguided or overly entertainment driven.

Thank you for dispelling the UAP garbage.
Time stamp would help. UAP = unknown areal phenomenon. If you see something which you can't identify then that qualifies. It's unknown, so I don't see your issue with it. 22:25 YW.
3 states and 100 people with me, saw what seemed like a meteor coming in, only to change direction and speed, like a check mark (moving much faster going out). I don't know what it was but it would definitely fall under ufo, uap territory.
3:13:50 Very good point, I think the Atheists which EmergeHolographic is talking about are making a big mistake by just claming reincarnation is impossible. It's true that people who teach or believe in reincarnation don't know really and are just imagining and pretending. But the truth is also that Atheists don't know the opposite either. It's a different question from that of a creator-God which cares about how you act and think. That's truly absurd imo, and one can see clearly that the notion of a creator and personal God stems from human desires, which are that of primates, and premature sloppy extrapolations from everyday life experience as opposed to careful rational consideration of established facts, logic and fallacies. I claim with reincarnation it's different. I'd argue against commonly taught notions of reincarnation which imagine any meaningful connection between past and future lives, though, or an organized or directed reincarnation. It would be rather chaotic. To answer his question I'd say pre-life and after-life death aren't mutual exclusive, but from our perspective different in character in that we know about pre-life death that it is followed by life 100%, while about after-life-death we know nothing. Trivial. But for his/your consideration, isn't the crucial question if there was a "we" that was dead before coming to life to begin with? It's yet to be clarified what it is which puts "you" in exactly this your body and not another's. There's already problems with the common notion of "I" if you consider that a meaningful sense of continuity is only made possible by memory. Of course there are Idealists, Dualists who assume we have access to memory apart from our body or (known) physical world but I doubt that. Next, with our neurological knowledge, while limited, I claim we can safely conclude that our sense of unity in oneself and of identity are artificially constructed and integrated by our brains/bodies. So far it seems to me that virtually everything we refer to as "I" consists of information, which is being held in the medium of our body, and is entirely dispersed into white noise with its death. However my personal take is that in order to experience qualia, there has to be a "Cartesian Theater", a projection surface. And as long as we don't know its nature, and if it's desintegrated together with the body or not, we can't rule out the possibility that the same projecton surface that's featuring our current life experience will be used for another after our death. Last, I have a suspicion that timeFLOW (not time) might exists only as a projection from perspective of a conscious being. That means, before and after life the very notions of "before", "after" and "now" would be meaningless. Maybe not, but it's worth consideration. My best bet is death is like a much deeper form of anesthesia. You die, you are seemingly instantly reborn but maybe who knows how many 10^10000 years later in who knows what form, with no recollection whatsoever of your past to refer to and no meaningful connection between lives.
If it was "some guy" I'd be inclined to agree with you Sean. BUT David Grusch is not just some guy. He's had top clearance level in his previous roles and has now given direct evidence and further direct witnesses in a classified environment, to congress, since the hearings too. If it's nonsense, why has he not been arrested for lying under oath at the very least? Something is going on that is quite bizarre.
But what is a field? You need to distort a field to make a motion in space, well then how about distorting a gravitational field whatever that means, we don't even know what a gravitational field is, but at least some of the fuzzy pics may well reflect some kind of a space/time distortion taking place, and last, Sean's opinions on the UAPs are his own opinions, in no way they represent any official gov nor public/scientific stance on this peculiar subject.
At the moment I don't have the time to watch or listen to such long podcasts, unfortunately. But I'd like to know what Sean thinks on the Oppenheimer movie. I watched it a couple of days ago and loved it (although it left me, obviously, quite appalled by us as a species because of how pathetic our priorities can be even in the face of possible self-elimination).
If Sean has already discussed the film and if anyone, who watches the podcast constantly, would point me to the right episode where I could hear his thoughts on it, I'd appreciate it greatly. Thank you.
(In case Prof. Carroll himself reads the comment, greetings to you, sir! Please, share your thoughts on the movie if you haven't already:))

WHY DOES HE SOUND LIKE ONE OF THE CHARACTERS OFF THE MUPPET SHOW
You really blew this post, On covid !
Most people working day jobs are interested in making money. Day job physicits do the same. At the end of the day too many questions unanswered, but on the other hand too much material to cover
These Korean "scientists" need to reprofession in K-Pop. Their superconductor has been debunked as a hoax by now.
43:00. The main misconception in the interpretations of quantum mechanics is that the equally probable nature of phenomena implies their equivalence.* Moreover, not only at 50/50, but also at 99/1. However, equality and equivalence are completely different things, even if they are causally related; for example, all inertial reference systems are equal in SR and QM, but far from equivalent. Obviously, if a dead or a living cat, the spin of entangled photons up or down, pairs of socks or letters marked + or - in different parts of the world are equal, then they are not physically equivalent; and also, branched universes. When an tails falls out after a coin toss, then they talk about the collapse of the wave function, when tails and heads are just equal, but not the same even not only for numismatists.That is, these are physical parameters of different physical phenomena, and their representation by a single wave function according to Born is ridiculous.
For example, when energy E=mc^2, then mass m=E/c^2, since they are parameters of the same physical entity, and therefore equivalent.
For comparison: in GR, in a gravitational field or in an equally accelerated frame of reference, all events are not only equal, but equivalent*, so Einstein criticized QM for not being as radical as RT.**
Unfortunately, he himself did not notice that GR was QG...
---------------------
*) - In logic, this is the basic law: the law of identity.
**) - The equivalent Universe can only be the accelerating Universe itself.
***) - It seems that the uncertainty principle is the result of a misunderstanding of probability/equivalence.
In the Heisenberg inequalities, the mathematical apparatus was formed before the interpretation of their physical essence. It is funny that these inequalities indicate that there are no exact values of coordinates and momentum vector in the states of microobjects at the same time; and thus exclude the equivalence of these parameters.
Addition.
By the way, RT is even more radical: "Two world points located at zero distance from each other do not necessarily coincide." (Pauli, RT, paragraph VIi, Four-dimensional world). This means that with each successive occurrence of even the same result, for example, tails (or heads), both of these events differ from each other, that is, they are not equivalent. Thus, a particle cannot even be in one state at the same time.
David Albert doesn't believe what he says about probabilities. Dare him to a bet.
6:51 Makes me think of Lister of Red Dwarf, he's a superconductor as well, you could send any curry through him.
23:38 Exactly, i thought it was a nothingburger from the start, and it has only gotten worse as it progresses. It's a giant mess.
What i hoped from it, was maybe some more forthcomingness from any party that could possibly share anything worthwhile, and maybe have some international initiative to look into claims and debunk them officially.
I never believed that there were ships and bodies, especially without any evidence, it's all hearsay and it's all made up, unfortunately.
25:25 Hah, exactly! I think i commented on that on the last episode, he totaly ruined it when he started about the holographic principle, i was flabbergasted.
Thanks! U sound like a contemporary Einstein. And your spiels, I must say, extend beyond the box and are applaudable to the nth degree. Kudos to u! However, in ALL your notable brilliance, u fail to acknowledge the Bible, the Word of God. Jesus Christ is the Way, Truth, and Life. And UNLESS u repent and make Him the Lord of your life, u will invariably wind up in Hell, where NONE of the staggering info in your database can save u. The fear of the Lord, the beginning of wisdom and knowledge.
Ah yes the ideologically neutral Republicans...
Correct, they exist.
Sean I've been listening to your podcast since 2019 and even when you have non experts on (I'm a professional poker player and the 2 poker players you had on are very far from being experts) I still give it a listen. But the rebuttal to the question on UFO's is just factually incorrect. David Grusch isn't just "some dude," he's a decorated combat veteran of 16 years for the USAF. The second factually incorrect statement you made was saying that the majority of UFO sighting's happen in the United States. Most sighting's happen in different countries, Congress was specifically talking about sighting's in America because that's what is most relevant to the hearing. Also just because David doesn't understand physics at a deep level like you and incorrectly used the holographic principle doesn't mean what he is saying is false. The "no sense" argument is only illogical to humans, you can't use anthropomorphic reasoning when speaking of alleged aliens. All that matters is data, and there is loads of it if you do some research on the topic. As someone who uses Bayesian reasoning everyday in his job, I'm well versed in how conditional probability works. But like Michio Kaku stated, the burden of proof has shifted in this debate. Thanks for your time and I hope you do some more research on the topic (both in poker and the UAP debate).
A 'decorated combat veteran' is just some dude. I understand that people like to lionize people but it doesn't make their testimony into evidence. EVERYONE believes a camera more than ANY human for example.
@@CorwynGC Everyone is just "some dude" then but that's not what we mean when we say that phrase. I think the majority of the academic community feels very similar to Professor Carroll when it comes to this topic so it's not surprising at all. Time will tell.
@@bertjames9661 No, some people ARE trained in evaluating evidence. They are not the same people as those trained to make decisions to murder at 600 miles per hour. But that aside, nobody should give much credence to one human's claims. Especially on hypothesis with such a low prior. What is the likelihood ratio of interstellar travel compared to one human's brain having a weird quirk? Tiny.
@@CorwynGC It's not one person's claims though that is the issue. There have been over 40 people that have come forward. It's a moot point without concrete evidence so time will tell.
@@bertjames9661 The likelihood ratio on 40 people is not significantly higher even if they could be shown to be independent observations (which also seems unlikely).

I am disappointed that Sean called David Grusch a conspiracy theorist..
I doubt very much et has visited our shores..
But to denigrate any whistle blowing attempts seems nieve on your part sean
Maybe a bigger problem that he is by his actions showing the corruption in the pentagon with defense government contracts
They need a large alien spacecraft to be landed on the WH lawn for all the press to capture images and press conference with the WH spokesperson to make an official scientific declaration that they have visited the earth.
Yeah it makes me sad too. David Grusch is not some nut job he is an air force veteran with high security clearances. People are afraid to have their world turned upside down imo.
@@bertjames9661Why do you think that "air force veteran" and "high security clearance" are somehow incompatible with "nut job"? Paid murders is not where I look for accurate evaluators of evidence.
Wow Barbie was the worst. It's full of woke ideology and man bashing from start to finish.
Not sure why everyone is so concerned with everyone else's politics outside of "are you in my camp or theirs?" Truly pathetic especially on a science channel. Sean please don't indulge them even if you want to answer, it is not helpful or insightful.
Two hundred thousand people died unnecessarily because the POTUS at the time politicized a virus. THAT was mixing science, which he ignored, and politics.
