#science #physics #ideas The Biggest Ideas in the Universe: Introduction 221,475 viewsMar 19, 2020 Sean Carroll 154K subscribers This is an introduction to a series of videos I'm planning, informal discussions of some big idea in physics or related fields. Symmetry, space, matter, things like that. Within a few days of the release of each video, I will look over questions that have been asked, pick some of the best ones, and make a separate video to address them. Update: yes I (now) know, the audio is only in one channel. Sorry! YouTube doesn't allow for fixes to things like that, but next time will be correct.

I am completely new at all this, so any constructive pointers on format, recording, etc. are welcome. #science #physics #ideas #universe #learning #cosmology #philosophy #math 719 Comments rongmaw lin Add a comment... Veroosh Tarot & Astrology Horoscope Veroosh Tarot & Astrology Horoscope 2 years ago Dr. Carroll please put out a lot of content now, if you can - its so helpful and calming. Im excited for this series. 18 Aprender Idiomas y Cultura General con Rodrigo Aprender Idiomas y Cultura General con Rodrigo 1 year ago Thanks for all this! I know you from YT and I love your work. I’m in for this journey! 53 Dave Lambourne Dave Lambourne 1 year ago These videos are priceless Sean. I’m starting a physics degree in October and putting in some groundwork first (I’m coming back to learning after being inspired by your podcasts). It can be quite daunting and these videos have given me great confidence, along with the maths work I’ve been doing on the Khan academy website. Having access to this information and to be guided by teachers like you continues to inspire me even more. These are the outstanding positives that the internet can bring to people from all over the world, along with the in depth platform the provide. Thank you so much Sean! 😊 5 Mirrorgirl Mirrorgirl 2 years ago I didn't think I could love you any more, then there's this. Thank you so much for all your amazing content. 38 Christopher R Chociey Christopher R Chociey 2 years ago @Sean Carroll. Thank you for everything you do. You have a great way of teaching. You're voice is easy on the ears. I greatly appreciate the time and effort you put into these videos. 48 0797cjm 0797cjm 1 year ago This guy is truly a living genius. It has to be a rare gift to be this smart but able to educate others on such a fine level in all difficulties. 6 Peter Deutscher Peter Deutscher 2 years ago Always love your content...mind releasing it with audio in both channels? :D 56 Ross Smith Ross Smith 2 years ago (edited) As much as I love conversations and interviews, it's sometimes easier to follow the thread of the topic when it's done in this type of lecture format. Thanks Sean! 4 Doctor Noxadus Doctor Noxadus 2 years ago Sean, I just wanted to say that what you do is amazing, talking and sharing knowledge and big ideas, inspiring to learn and be curious about the world. Also seeing that this is fun for you makes me feel good! Thank you! 3 Johnny B Johnny B 2 years ago Looking forward to the info, I appreciate all your efforts and time dedicated to educating us in the masses. Great choice of backdrop too. 10 Trevor Gregory Trevor Gregory 2 years ago Really looking forward to this. Thank you for taking the time and effort to help educate the masses. 1 Blue Bliss Blue Bliss 2 years ago As another person mentioned below, try to stand farther away from the green screen. Make sure the screen is well lit so you're not casting shadows on it. If you have the space (and time) you can put a couple lights behind you to light the screen evenly from either side. Then another light on you, try that from an angle so it creates some nice highlights and shadows on your face to avoid that Dunkin Donuts at 3am look;) Also, if you can move the camera a little farther away from you, it'll lessen the distortion. Adobe After Effects has a nice keying plugin that works well and easily. Anyway, I really enjoy your lectures and podcasts and audiobooks. Lately I can't help but wonder how to port myself to one of the many worlds without a pandemic ...? Oh crap, I guess an infinite number of other Me's are already there.... 37 Alistair Spence Alistair Spence 2 years ago I am really looking forward to this series. Thanks for doing this! 3 Dizaster199 Dizaster199 2 years ago This is great! Looking forward to the series! Thanks Sean, for all that you do! Vero Schia Vero Schia 2 years ago This is wonderful! I'm looking forward to the weekly videos! Thanks Sean, you are by far my favorite teacher and public intellectual! :) Superluminal Superluminal 2 years ago This is great - thank you, Sean! Cannot wait to see your upcoming videos in this series. Keep it up! Keith Bidwell Keith Bidwell 2 years ago (edited) Strongly for it! Thanks for taking the time and effort. Deeply appreciate being able to learn while in this circumstance. Could we start with a discussion of scale? I think a big issue with understanding the quantum is dealing with how very small it all is. 1 Yitzchok Ahisar Yitzchok Ahisar 2 years ago This is very exciting! I am very much looking forward to learning more about physics with you! 1 Pupa pupps Pupa pupps 2 years ago I love your mindscape series, and this one i can't wait!! <3 thank you Sean, people like you are priceless on youtube. Smishi Smishi 2 years ago This is nice. Nevertheless I would also like to hear the big course with all the equations from Sean sometime. 60 C S C S 2 years ago This is great! I would love to understand better Penrose's CCC model and how this relates to other competing models that try to describe the origin (and future trajectory) of the universe 3 boo Jay boo Jay 2 years ago (edited) Hi Sean, you're my favorite (living) physicist. Just wanted your thoughts on Einstein's condolence letter to the family of a close friend of his, Michele Besso, who had passed away shortly before he did. Is this an accurate view of how we should see the world? Or is holding onto this thought merely a coping mechanism and not really illustrative of reality? Could further understanding of time definitively make the case that everything in the past is lost forever, or that it will always and has always been there? 19 Tyler Mauldin Tyler Mauldin 2 years ago I am captivated by the background art! I hope you keep it in future episodes. 11 William Knudsen William Knudsen 2 years ago Thank you Sean. I will be watching. I love everything science. 10 Gareth Butler Gareth Butler 2 years ago This is brilliant. Thank you so much for doing this. Already looking forward to the next one! Earwaxfire909 Earwaxfire909 2 years ago I would like to see a list of the golden dozen experimental techniques in physics today and why they are so important! 2 Jason Korn Jason Korn 2 years ago This is great news! Thank you for doing this Sean. Darren Brown Darren Brown 2 years ago This is very awesome! I'm along for the ride and look forward to more videos as I enjoy the solitude of our collective isolation. I don't know if you're looking for questions now, likely not, but I'll throw one out there. If many worlds theory is true, doesn't that in a way solve our dilemma for life after death? I may die in this lifetime, but the infinite other me's are still coming into and leaving existence forever and ever. Does many worlds change our attitude towards impermanence? 1 Bruno Jäntti Bruno Jäntti 2 years ago This is an excellent idea, Sean. Much appreciated and thank you for all of your magnificent work. You have basically radicalized me, I've become a theoretical physics aficionado (here, theoretical physics aficionado - > a person who enjoys the field but isn't well-versed enough to contribute anything to it). Omer Subasi Omer Subasi 2 years ago Dear Sean, thanks for this series. Looking forward to it. 1 Alleyway Mind Hook Alleyway Mind Hook 2 years ago The timing couldn't be more perfect. Thanks for doing this! Neptune The Mystic Neptune The Mystic 2 years ago This is brilliant! Thank you Sean this is just what we need RN!! Bernard Wei Bernard Wei 2 years ago Can’t wait, love your books and your podcast. You did very well in explaining physics and many topics for layman like me who are interested in science and big science but do not have the necessary background to learn them formally. Denis Dmitriev Denis Dmitriev 2 years ago Sean, could you consider making a video about different physical constants, like gravity G etc. And why sone of them can be measured in high accuracy and some of them cant. Thanks. 2 Aaron Aaron 2 years ago Wow, thanks so much for this Sean. The visual part is also great. It adds to the experience SEEING you speak! 5 j delaplaya j delaplaya 2 years ago Hi Sean. Thank you so much! Great idea!........ What's your thoughts on constructor theory? Does it risk us moving once again to an anthropocentric view? If so, is that necessarily a regressive calibration? That is, given the many worlds view and the potential rarity of this particular state of entropy we, as human beings are witness to? Or indeed the product of? From philosophical standpoint I find it rather liberating, it allows us to once again regard our experience as merely an elemental function of the universe we are experiencing.......and a bit of painting after a hard days math 1 Scott Worthington Scott Worthington 2 years ago Outstanding, Sean. Thank you for this. Count on me to be here. 1 Adam A Adam A 2 years ago I really enjoyed your great courses on Time. Looking forward to this topic again, maybe a podcast that explores it again? 1 Bob Tarmac Bob Tarmac 2 years ago This is so cool, thank you. I would love to have you to address infinity. Not necessarily mathematical infinitely, but rather absolute infinity. Does such a phenomenon exist? If it does, is it composed of all possible states as an infinite solid? An absolute infinity of individual “Lidded” infinities? Pass through any one lid [big bang, black hole] and a new infinity exists on the other side. 1 Ronak Batavia Ronak Batavia 2 years ago Thank you for the series, Sean. Looking forward to seeing you episodes here on YT. Could you please make an episode about The Fermi paradox ? Immanuel Jerom Immanuel Jerom 2 years ago I can't wait to wrap my head around the emergence of space-time phenomenon. Keep up the great work Professor! 1 R Genericson R Genericson 2 years ago Awesomeness! Can't get enough of this good stuff! 1 pipertripp pipertripp 2 years ago This sounds fun. Looking forward to it. I'm already learning a number of things in my free time, so I like the idea that this will be a bit more casual. Fulvia Fiorani Fulvia Fiorani 2 years ago What a wonderful idea! Thank you for doing this. Hershy Silver Hershy Silver 2 years ago Dr. Carroll, you are awesome. I appreciate your ability to relate complex subjects in a simple, straight-forward manner. I am a big fan and follow your talks on YouTube. I recently became a patreon of your mindscape series. Thank you for sharing your knowledge and insight. You are making the world a better place. Rock on. 👍 1 Madara Uchiha Madara Uchiha 2 years ago (edited) Hi Sean, nice to see you talking. I worked with you book(geometry and spacetime) alot during my course on general relativity, it helped me a lot. libraclown5 libraclown5 2 years ago Oh this is so amazing! I really stoked to see the next video -- is there going to be anything about the recent developments of how we are detecting gravitational waves? My imagination is running wild trying to think of how this will change our perspective going forwards in Cosmology =) Steven T Meer Steven T Meer 2 years ago Your green screen and text window looks great Sean. Thank you for giving us more content to help occupy our time and absorb more knowledge during these difficult times. You are awesome! Victor Dequidt Victor Dequidt 2 years ago Awesome idea ! Thank you, this will be much more easy to go in :) Gary Montgomery Gary Montgomery 2 years ago Love it! Great idea. If you're taking requests, I've always wanted to hear your opinion on the US Navy's admission that they have videos and and highly credible eye witnesses depicting radar and visual targets behaving in ways that suggests new physics. Sebastián Fuentes Sebastián Fuentes 9 months ago Thank you so much for these videos Sean! I really appreciate it! 1 remogaggi82 remogaggi82 2 years ago Thanks for all you do Sean. Love learning from you. 1 Retired Retired 2 years ago Thank you for this Mr Carroll. Love your lectures as well. You explain your ideas in a clear way without any arrogance. MrOreo76 MrOreo76 2 years ago Thank you for all your videos Sean! It helps so much! Andres V Andres V 1 year ago You are amazing for doing this Sean, thank you so much, I'm from Chile and I'll do my best to translate the knowledge you spread for people around here. I hope to meet you one day Simos Simos 2 years ago Thank you for your free content on General Relativity, it was of major help to me when I started studying GR. And also, what helped me afterwards was your book on GR which is great. I really like that we live in an age that I could express this from the other side of the world, so I just did it! I am looking forward to the videos, fantastic idea! Eduardo Reyes Eduardo Reyes 2 years ago Thank you Sean, you are the best thing on YouTube right now!! 1 Amr Abdellatif Amr Abdellatif 2 years ago Yes! Give me more of Sean Carrol! 28 Manu Manu 2 years ago Love this idea. I've been thoroughly fascinated by the core mechanics of what we observe - symmetries, underlying formulas which can be numerically explained et cetera. Tomasz Zajaczkowski Tomasz Zajaczkowski 2 years ago Great work Sean, thanks for your work!!! bob ross bob ross 2 years ago Mr Carroll you are a brilliant teacher, and I'm so glad that something this awesome came out of this quarantine period Anzan Hoshin Roshi Anzan Hoshin Roshi 2 years ago Thank you, Sean. A video series will be very useful. victor victor 2 years ago wonderful!! thank you so much for doing this! 4 Derrick Derrick 1 year ago Thank you for this. Looking forward to explore this series. Ariella Ariella 1 year ago Thank you for taking the time and effort to share your knowledge! Looking forward to diving in! warrenbach warrenbach 2 years ago Great idea, Sean, and am looking very forward to the videos. You've honed the skill of presentation to the nth degree, and the result is you're the best and a pleasure to watch. I'm also interested in the quantum explanation of how your hair turned green. Thanks. Alfred Maldonado Alfred Maldonado 2 years ago Fascinating stuff Sean, keep them coming 👍. Already propped up my calculus books for dust off during the lockdown ☺🛫. Eli CP Eli CP 2 years ago Thank you! I work from anyway and would be super happy for this regardless. I hope a silver lining is maybe people taking some time to find all the great educational content that is out there. gkelly34 gkelly34 2 years ago Thank you Sean! I’m so looking forward to this. Dennis Donovan Dennis Donovan 2 years ago I am so looking forward to your following videos … Thank you Professor Carroll! 👏🏽👍🏽 freak kitchen freak kitchen 2 years ago (edited) Greetings from Russia, Sean! I'm looking forward to seeing your next videos. I've got questions mostly about time and black holes, dark energy. - If I fell into a black hole and looked at the remote stars and galaxies far away above me how would I see them? How would anything far away be seen from a location with extreme gravity? - Everything we know is located within the Space, so can we imagine anything outside the Space? Is there a chance that something could exist whithout space? - The Universe is expanding hence it has a border or something like a wall, could you explain what it looks like? - If we have two entangled particles and plant one near a black hole and the other we leave somewhere with a weak gravity does that mean that despite the great time difference when we change their spins they still interact simultaneously? - A lifetime of a regular small stars like our sun is longer than massive stars but if a massive star is located near a black hole does that mean that it would live longer than a small star even though they formated at the same time? Best regards, David Archie Lundy Archie Lundy 2 years ago Can't wait for these Doc. Thanks for all your outreach - it's priceless. Sandra sandra Sandra sandra 2 years ago (edited) Thank you for your good initiative. I love listening to you, as you are a brilliant scientist and also very skilled in teaching common people, even those who, like me, lack a formal mathematical background. I watched every your video here on YouTube, the great courses lectures are really great. I read "the big picture " and I am reading "Something deeply hidden". I have learned a lot from you. About the many worlds I'd have a question for you, I apologize if it's too idiot but I can't answer by myself in a rational satisfactory way. How comes that each one of us, despite so many splits, finds himself always in the same world as his son, friends, neighbors etc? Thank you so much clearair clearair 2 years ago Thanks Sean .. I’ve followed your work for many years as a layperson - you are a great communicator. qcxcq qcxcq 2 years ago Sounds amazing. I hope for something between Cosmos and The Carroll Lectures on Physics. 1 pozablo pozablo 2 years ago Thanks for this. I think the green screen and lighting and audio are perfect. Very much looking forward to episodes on Naturalism, and hope you will be addressing monism/no-self. 1 Tabor Talk Tabor Talk 2 years ago Wow! Yes, Sean mentioned this new feature in his last podcast with Tara Smith. I’m a kid in a candy store!!! Great stuff! 11 RSky Car RSky Car 2 years ago (edited) Hi, Sean! That's great news and I'm sure your new type of stream will extremely successful, considering a particular period of time, not only for long time fans but for everyone who didn't lose yourself in infinite rulon of toilet paper. And by the way, I like the background behind you. Best regards! bryan roland bryan roland 2 years ago Thanks Sean. I'm a teacher in Spain, where a state of emergency has been declared. I'm bored and stuck in my house with little to do so what could be better than a series of videos from my favourite science communicator to relieve the monotony. Marcin Staniewicz Marcin Staniewicz 2 years ago This is so great. I'll spread the word among my friends about it. Thank you very much! Carlos Carlos 2 years ago Great Sean. You just made my day. Looking forward to this. Even with mono sound you made me happy. In stereo this should be a treat. This should make staying indoors fun. rares mircea rares mircea 2 years ago 5:07 Great! You can also bring up pictures and diagrams and all sorts of visual metaphors to help with understanding the ideas 👌 Stainless Steel Rat Stainless Steel Rat 1 year ago you are a bloody legend sir .... love your lectures and style of teaching David Brockett David Brockett 1 year ago Sean,you are awesome!Keep doing what you're doing! David W. David W. 1 year ago Thank you your sharing your knowledge with all of us! D Wnright D Wnright 2 years ago Awesome Sean. About time! Look forward to you terrific insights. Antonio Fonseca Antonio Fonseca 1 year ago A Big Thank You, Sean, for this generous, brilliant, initiative. I just across the videos and intend to make good use of your offer. Bests. Jason Beary Jason Beary 2 years ago THanks, Sean. I'm going to use this for my high school physics students while we are all socially separated during the Covid-19 pandemic. 1 Jon J Jon J 2 years ago I like this Sean. I have been waiting to see more video podcasts from you. Maybe a live one now and then? Darin George Darin George 2 years ago (edited) Great idea Sean, I look forward to the videos. I would like to suggest 2 topics...1.) During the so called 'Big Bang' the elements that dominated were hydrogen and helium and trace amounts of Lithium and Beryllium. A what if scenario...say it happened the opposite. What would reality look like if Lithium and Beryllium dominated the universe with trace amounts of Hydrogen and Helium? 2.) "Time" is a topic we hear a lot about, but I was wondering if we could expand on this...Time seems to work differently the smaller the organism much like mathematics. For instance a hummingbird sees its surroundings vastly differently than humans. To elaborate, I want to speak of the lifespan of a quark. I am no expert but my understanding is that an individual particle has a very short lifespan...I guess what I am trying to figure out is if time is just size perspective? Thank you for your TIME! Darin D D 1 year ago Covid has shown us who the real educators are. Thank you for this outstanding series. xViolatorx xViolatorx 2 years ago I like it, looking forward to the series! Erik Erik 2 years ago (edited) My kind of series. Let's go! Thank you very much. You've been my favorite physicist for a long time. acardnal acardnal 2 years ago Thank you for doing this. Great stuff! brian meanor brian meanor 1 year ago I love everything you do I’ve been watching you since I found you on the great courses years ago.the way you walk us through explanations is the best I’ve experienced.thank you for all you do for the world Of physics and helping a simpleton understand .also I love your books as well I got the audio books and you got me to and from work for a long time. TheVulcanJedi TheVulcanJedi 2 years ago Sean Carroll (in Liam Neeson voice): "If you are looking for a cure for the corona virus, I can tell you I don't have that. But what I do have are a very particular set of skills in physics. Skills I have acquired over a very long career." 49 Daniel Uribe Daniel Uribe 1 year ago (edited) You Sr have a great mind but an even greater spirit! Thank you so much for gifting your time and knowledge to humanity Christian Drewing Christian Drewing 2 years ago Thank you for this series!! I just discovered your playlist. And also thank you for mentioning the great courses. I made my high school graduation in physics and mathematics but changed lanes to financials in my later career, but physics is still my absolute favourite in my private life. This is why I am really fed up with all these NatGeo and Discovery channel documentaries - just a profane touch of a topic where I am eager to gain more knowledge like a dry sponge has desire for water. Thank you very much! nebselpam nebselpam 2 years ago Love the idea, really looking forward to this Mike Ghoshal Mike Ghoshal 2 years ago Thank you Sean. It's very kind of you to do this public service, but also introducing science to the community, which is of absolute importance for all. I have listened to you numerous times, and all are excellent. Very clear and precise. Cheers. Michael McCaffrey Michael McCaffrey 2 years ago Can't wait to see where you take this series! 1 JONATHAN KISER JONATHAN KISER 2 years ago Fantastic idea! I look forward to every episode! aceofspades25 aceofspades25 2 years ago (edited) Hey Sean, this is a great idea, thanks for doing this! Just wanted to let you know that your sound is only coming through one channel (my left ear) Also, what is that background image? I love fractals but I've never seen that one before 3 skateebee skateebee 2 years ago This looks awesome! Looking forward to it! Guy Josephs Guy Josephs 2 years ago Wonderful idea Professor! Im huge fan of the great courses and got the plus while ago and have started your lectures on dark matter dark energy =) looking forward to this that you have going on here also. Li Li Li Li 2 years ago (edited) Hey Sean, you're one of my favorite physicists! I'm looking really forward to these videos! I listen to every episode of Mindscape! Why is your hair green? And why is the sound all on the left side? I'm sure you'll be answer these questions because, well, you're Sean Carroll! : ) UPDATE: Oops- I should have read more of the comments! >blush< Never mind! 6 Eponick Eponick 2 years ago I recently stumbled upon a paper from 2005 by Xiaodong Chen on 3D time and found his concepts fascinating. I was wondering if you have looked into this and what you think of it as an Everettian? Diego Ochoa Diego Ochoa 1 year ago I recently discovered Dr. Carroll and OMG!! I have all his books already, I’m halfway through The Big Picture. Really mind-bending, eye opening knowledge. Thank the Universe for him!! Ernest G. Wilson II Ernest G. Wilson II 2 years ago @SeanCarroll First let me say thank you for taking the time to make these videos and share them with all of us! Can you please describe your technical set up for making this video series in a little more detail? Which green screen did you buy? Which software are you using? How are you doing that with your iPad? Sorry, I know these questions are not specifically on the topic of your video series, but you did mention them here in this very first video and I'm very interested the underlying technology and costs involved that made your video series possible. Thank you. I am of course subscribed with notifications turned on and thumbs up! Matt Beavan Matt Beavan 2 years ago This is awesome! Looking forward to it, thanks! 1 Manolis S Manolis S 2 years ago Good luck with the new endeavour. Please consider introducing simple math as well, explaining some key equations in an easy understandable way if possible. It really helps and enhances understanding for all of us not physicists. Stoyan Velikov Stoyan Velikov 2 years ago Hello Sean, first of all thanks for everything that you teach. What is your view on Lee Smolin's idea of the Universe? Philo-Sophy Philo-Sophy 2 years ago Thank you Sean! This sounds GREATTT!!! 1 Michael Donlin Michael Donlin 2 years ago Good stuff Sean! Very cool and thank you. soulremoval soulremoval 2 years ago This is very exciting, love your work Dr. Carroll Hans-Petter Bekeng Hans-Petter Bekeng 1 year ago I so love you and your science teachings. So happy you found your way to Youtube eventually too. We need more science and less nonsense on Youtube. Thank you very much for your videos, Professor Carroll. They are very much appreciated. Foghorn Leghorn Foghorn Leghorn 2 years ago Awesome idea. Thank you for your efforts. frits germs frits germs 2 years ago Thank you very much. I have read a number of your books. including the last one. It is always a joy to learn from you. enotdetcelfer enotdetcelfer 1 year ago First few videos: 20-50 minutes Last few videos: 1.5-2hrs Love it, watched a couple in the middle that came up in search results but they were good enough I'm starting from the beginning. Thanks for doing this!
