Dr. Carroll, I know I'm not the only one who would like to thank you for your efforts which are not only admirable but also a remedy for many of us in these challenging times. Would also like to extend my appreciation for our little resident community we have here. Wish all of you well & please keep up the good work!
loving that you 're producing so much content lately Dr. Carroll. Thank you. the comment on Dr Carroll's way of speaking is spot on. personally at least I absolutely find it very easy to listen to and it definitely adds to his ability to convey deep concepts to even us lay people.
"Static interpretation of time" is the mis speak of Judith Marsh (28:43), which is how it is spoken of from Albert Einstein's special relativity and Hermann Minkowski's extension of special relativity. (not static time of course)
I can't believe my eyes, Sean Carroll, which I read very fondly, is on UA-cam and we answer questions. That's amazing! Q: Dear Sean Carroll, what do you think about the fate of string theory? Will it be proven in the future or will it lose its claim? I will also ask this question to Brian Greene :)
Dear Sean Carroll . Regarding extracting energy from a black hole (1:28:46 to 1:30:25), I would recommend trying to obtain a "standard industrial neuble" (that is the tricky part...). The Hawking radiation would generate almost 350 MW for a 2500+ Gigayears. Black hole calculator here: www.vttoth.com/CMS/physics-notes/311-hawking-radiation-calculator The surface temperature of 100+ GigaKelvin may present a bit of a technical challenge though.
You're like a total Spock dude! I love it, man. The way you rearrange peoples questions into one that can actually be answered "logically". That's really enjoyable to listen to a very helpful service, Thank You!
"You are using a lot of words that are either being used in a slightly technical or slightly nonstandard ways" is the most polite description of technobabble I've ever heard ;)
One thing I noticed about your speech pattern is that you only rarely pause with an "eeh" or equivalent. It seems you elongate words when you need additional time to think. Did you purposely work towards removing "eeh" and "eer" from your speech?
01:19:49 The one number for the universe obviously would be 42. And then we'd need a bigger universe to find out what the question was... - maybe that's why the universe is expanding: it's trying to find the right question...
Sean Carroll is better than a Hollywood blockbuster. Dear Sean Carrol, I have to travel 25,000 lightyears within 7 weeks. How can I do it? By the way Sean, your voice is lovely, soothing and imprinting..
I think what people believe abstractly and believe implicitly are two different things. As someone who deals in QM I am sure you bumped up against this distinction.
"Clocks still tick at one second per second, regardless of whether there is a cosmological constant or not". I don't know whether this is true of the universe we live in, but it is exactly the kind of question I would like to see investigated much more carefully. It does not seem to me to be self-evident. It may describe a permissible solution of Einstein's equations but that's quite a bit less interesting of a statement. Your earlier comment about a uniform metric being associated with a universal proper time is, I think, a much more interesting statement, and I would really encourage you to think more deeply along those lines. I have a feeling deep in my bones that there is something incredibly important there...and anyway, it's not like we have any better ideas about dark energy.
Dear dr. Carroll, there is consensus about the age of the Universe being about 13,7 billion years old. My question is: what does a "year" mean when the earth orbits around the sun do not exist. How can one determin the duration of a "year" before the earth existed.
That question doesn't really make any sense to me. A year is just a unit. It could be measured in minutes or blarublaberahsdjhses which is a unit i just made up. A year is still a year long after the earth is gone and the sun has burnt out. The same applies to before the sun. A year is still a year then too. It is just a unit decided by us based on our orbit around the sun
You need to add a question mark and pay him on patreon if you would like his answer to the question. You may get lucky and ask a question intriguing enough to inspire a patreon supporter to ask for you, however that is going to be a longshot. Good luck sir or ma'am!
ok so far i have learned quite a bit actualy thru the different science channels, my question is this, what if like a quark or q-bit being in a state of super position that when it is measured it stops in one position or the other what if the same pricipal could applied to the big bang?
are the split "universes" independent and non-interacting absolutely or could a separate outside independent observer still see an interference pattern (in which case the independence of the universes are just relative to observers entangled with the observed system)?
Wouldnt a counter argument to Dennets explanation be that if one doesnt have control over whether theyve been appropriately educated or are able to understand and apply the concepts of morality doesnt mean it is impossible for one who has been exposed to these experiences to apply their understanding of morality? Of course Im not suggesting these people have control over whether they want to be moral, just that morality, like anything else, is a learned behavior. I think there is a recent study that shows the universe isnt expanding at the same rate in all directions? Assuming it's true, does this change the need or application for inflation and or what would be your first reaction to how or if DM or DE could be influencing the distances? Also if this is true would this change the amount of entropy at the big bang?
On the topic of trusting an expert: In paleontology, I found you can see the specimens in museums, conduct your own phylogenetic analysis, then add taxa (as they are described) to see how that changes anything in the cladogram.

The algorithm used in Darwinian evolution would be same which is used for whole cosmic evolution. Whether the evolutionary process itself evolving through evolution?
We look at the universe and run the movie backward to get the age of the visible universe and the theory of the big bang. How about the rest of the universe outside of what we can see? If the entire universe is say, twice what we can see doesn’t that double the age? Or is inflation affected?
Thank you for sharing this video, I really like your personality and the topics are brilliant. Iam a big fan of Roger Penrose CCC theory, would love to hear your view on this idea.
what does it mean to say that clocks tick at 1 second per second? are you just saying that euphemistically or is it a precise way of describing it? isn't it just a tautology?
@@WitzyZed my point is saying a clock is a clock isnt really an informative statement. it's just saying "the law of identity" basically. "A=A" I don't see it meaning anything beyond that
There's no problem with denying free will but still holding other people accountable and having a legal system and forms of checks and balances on Behavior. Because that's all part of the system that we live in. You don't have to have free will to react to someone's behavior and do what is necessary to maintain order in a society. Let's face it the universe is a system we are systems everything is best thought of as a interactive system with feedback loops excetera! There's no problem with strictly saying there's no such thing as free will because after all no one chooses to be born no one chooses their genetic code no one chooses the forward momentum of the universe Etc! But with that said we naturally have certain reactions to each other and we naturally have a system that has a valve so the fact that technically speaking there's no free will doesn't mean we can't hold people accountable because that's all part of the system we live in. In other words if you look at it logically the criminal doesn't have free will but neither does the police and neither does the jury and needed as the judge they're all following the momentum of the universe Anyway it always amazed me that people could say well if there's no free will then there's no accountability but they couldn't see the fact that if the criminals doesn't have free will will neither does the judge and neither do the police. Why does somehow not having free will make the fact that we have a system that has taking hold on this planet a system of people and relationships why can't the phone momentum of that just play out. Anyway I always thought that was weird that people couldn't realize that no the criminal doesn't have free will but neither do the judges. They have abilities to learn into adapt to situations but technically speaking we're all products of the universe
I hear you I'm not really arguing the issue one way or another I'm rather pointing out that if someone says Free Will doesn't exist. Then the Criminal Who commits the crime is not free but neither are the police and neither are the judge and neither are the legal system I'm just pointing out that people's objection that if we have no free will than we have no responsibility doesn't take into account that you're basically arguing that the whole system isn't free so clearly people are still going to hold others accountable just because that's their nature that's what the universe is dictating I'm not arguing that this is the best conception of reality or there might not be other more interesting ways to discuss it I'm just saying that it always boggled my mind how someone could say that if there's no free will then we can not hold anyone accountable. But again that misses the whole point that our holding people accountable is just as much not free as someone committing a crime
@@elontusk610 okay but I will give you my best conception People have evolved to have a range of possible behaviors And the laws of physics tell us that it is impossible for any intelligence to know the future of the universe due to the fact that trying to gain information is an active process which influences the situation you are measuring So I think the best conception of Free Will is just the fact that people have a range of possible behaviors and we will never know what the future holds in any certain way But I certainly don't think any naive conception of free-will such as people are really free to determine their actions without any influence is at all realistic. Obviously people don't choose to be born and they don't choose the situations that they encounter. And they certainly don't choose the laws of physics or the nature of the universe or anything like that. Anyway Free Will is like many abstract Concepts it's a vague notion that simply denotes the fact that we have a range of possible behaviors and it is impossible to know how any of those behaviors will play out. It's also the feeling that we make choices and make decisions so in that sense it's a cultural construct that simply gives us a feeling of how to think about our relationship to society and the people around us. In that sense it's an abstract concept like justice or morality In that it is determined by our psychology our cognition and so on.
I recently heard about the theory that says there was no big bang and says the whole thing is the outcome of some quantum fluctuations. also, I want to know how space can be created. does bang created the space or space was already there for the bang, could you elaborate on that.
I think reality might be like a computer game. We are controlling our characters but there's a few second lag before the outcome. That would explain the brain delay experiment paradox. Sorry if this sounds crazy but iv'e had a few whiskeys. LOL.
I think that free will has been ruled out because of the brain delay experiment? A six second time lag to the moment we make a decision. Thats really depressed me. I hope there's a way out with QM.
Roman Ghenciu the light became transparent in the universe when enough matter and atoms formed to transport light through space, which was around 380,000 years after the Big Bang moment. Since then it has been 13.8 billion years and the universe has been expanding at (x) rate, so it has been expanding that fast and that long and right now from one side of the universe to the other, it is about 92 billion light years across. In another billion years it will be even larger.
Thanks for the questions and answers podcast. I use scale to visualize. The string theory 10^500 universes, for example, All the atoms in the universe, each with a universe of atoms and each of those atoms have a universe of atoms within, which is 10^240 and so on. To imagine the 10^80 number, the body contains 10^27 atoms, each of those would have a body with atoms in and so on. 10^27 isn't that far away from the millions, billions and trillions, we're accustomed to. It's easy to feel, yet difficult to visualize; a lot of concentration is required, it's like meditation, or astral projection. Have a great day!
"Pascal's Wager" encourages betting the farm on trillions-to-one odds. With all the possible gods (literally trillions), Pascal wagered his life on his one particular God. Dumb idea from the start.
Considering how horribly Pascal's life ended and how his decision brought him nothing but senseless suffering and finally a painful death, I wonder how anyone can seriously ask what believers would have to lose. He himself was the perfect example how bad it can get.
Question: Just watched Eric Weinstein discussing his theory of everything about geometric unity and the observerse. I can’t make heads or tails of it. Curious if Sean has listened to it/what he thinks of it.
