I remember when i spotted my first qusar with my telescope. The quasar’s name is 3C 351 and it is about 4.6 billion light years away. It took me about 45 minutes of looking through my scope and then reviewing my charts to make sure i am actually looking at a quasar. In my scope it looked like just another dim star, but it blew me away to think that i was looking at a mind bogglingly massive, bright, and powerful quasar that is 10% across the entire observable universe. It was incredible.
That's utterly incredible. Some real top-notch amateur astronomy right there, well done, my friend!!! I have the exact same experience, except all we're talking about for me are my first observations of both Uranus and Ceres hahahaha. I'll work my way up to your level some day I'm sure 😉
I really love how instead of just telling us what a quasar is, you took us through the decades of research it took scientists to figure out what was actually happening. Cheers for a fascinating video!
@@realityvanguard2052 that's why SEA deserves props. There's a lot of popular science channels that only describe what we know something to be after we've already "figured it out", not explain the process that brought us to that understanding. The history of the research and how our ideas change along the way is just as interesting!
@@leminjapan We live in a golden age of informative videos, my friend. Once upon a time, used to just rely on PBS docs for basic info, NOVA science now every Monday night, and just hope it takes you on a journey to the stars... Then when most of the space documentaries became available online in the early 2010's I'd be watching them like every day, only to have to listen to the same basic concepts re-explained over-and-over again in the hopes that maybe I'd learn something new. .. Do you know how many times I've had to hear about how many Earth's can fit inside Jupiter? OR that the sun holds 99% of the solar system's mass? haha or the basics of relativity and space time? Seeing that 2D representation of how gravity works using a trampoline or something xD IT'S NOT EVEN A GOOD REPRESENTATION! Not really... haha but I digress. Point is this had better be a step above those dark times xP or I would be back on Wikipedia.. He does a decent job reading it for me
More mindblowing than Quasars is how you can come up with this incredible quality in every Video. It is so on point that it truly outshines 99,9% of all space documentary’s. Hats off to you. Keep up the amazing work
@@Andromedon777 I don't know what I'm waiting for. I should get it right away, though I haven't bought it yet lol. Think I'll do when I get home. It looks REALLY fascinating!

No drama and calmly narrated, extremely well researched, factually precise, fascinating, and great graphics to accompany it all too. Your hard work has not gone unnoticed. This channel is up there as one of the best.
I love how I fall asleep every time I watch one of these, so I can watch it again next night. It takes me few nights to finally finish it. Interesting, but calming. Love it.

Even more impressive is the coverage of recent papers that could only be distilled by someone very familiar with the subject matter. Your efforts are deeply appreciated.
I'm 30 years old right now watching this. I've always been interested in space. For some reason I keep thinking about sitting in my grade school library back in 1997 and doing mundane tasks while this kind of stuff is happening out in the universe. It makes me feel infinitesimally small. Like I could be reborn a billion times and never get any further than bearing witness to these Universal events. It's quite humbling.
i feel exactly this way. whenever i think about the vastness of space i almost quiver at the thought of being that small and insignificant compared to it. but i love that feeling
@@mbukukanyauexactly lol. All the universes size makes me feel is that it’s meaninglessly big. The only thing that matters is what’s on our earth and in our solar system. If you want to know the true nature of the universe then find religion, because astronomers are not figuring it out anytime soon.
That's a common thing for many people including me, but one thing I must say is it helps sleep not because it's boring, It's quite the opposite, but it gives peace of mind and a feeling of welfare. Also if I fall asleep on say minute 20, I will be happy the following day cos I'll still have the 5 min catch-up plus the remaining 10 or 15 minutes to enjoy!
Been here for awhile and just wanted to say thanks, your content is part of my day almost every day. Always looking forward to the next one friend, Salud!
I read every astronomy book I could get my hands on as a kid. I always thought quasars and black holes were separate. Imagine my astonishment and duh moment when I found out quasars are black holes. The thing from which light cannot escape is ironically the brightest thing in the known universe.
Your videos are awesome and this one is on a league of its own. It's so good that even if it's over 30 mins long, it feels short and you don't want it to end. You show a deep and rigurous knowledge and one learns not one but quite a few things with every video, and also you give credit to people who devoted their lives to investigation and astronomy and maybe didn't get much acknowledgment outside the astronomy guild. Very well done young man and keep it up. Top quality content to feed the mind with curiosity, imagination and the determination to understand.
This is what really puts me to sleep at night! Nothing better then listening to the wonders of the universe as you slowly fade into the sleeping phase👍☺️
You have done something that no other person/show has ever done before: finally broke down red shift in a way I can finally understand it. THANK YOU! I have felt so dumb for so long but now I feel just a little but smarter. Thank you so much for that!
It's Ramadan right now and one of the things you do is wake up around 3 or 4 to eat breakfast and for the past, two to three years I have been watching your videos every Ramadan at 3 in the morning to get through my food before fasting, your videos are both educational and entertaining and its a treat to watch them every early morning while I eat :)

'Yes it's really called the Huge Large Quasar Group.' Welcome to letting astronomers name anything. -What part of the sky did we find it in? -Can I name it after myself? -How big is it?
@@kevinflaherty1 the letters usually represent what type of object it is and the numbers are just straight coordinates sometimes with extras like which telescope found it or the cluster its located in. I more referring to giving stuff a 'proper' name though. Observatories/telescopes work the same way (ELT literally stands for Extra Large Telescope)
This channel is incredible. Great and comprehensive info, no click-bait titles and not a single plead for likes or subs. The videos are practically animated white papers.
The best space channel! I look forward to each video and you can tell how much work he puts into each one and how much he loves the subject. 🌟 really amazing work
I love this channel. There's something philosophical and deep about the discussion of space here - it's unique stuff, not gimmicky, not too dumbed down and his voice is like a sage.
The Gamma Ray Burst Wall, Bootes Supervoid along with things like this are easily the most fascinating/horrifying things to think about in this universe. It's amazing to think about seeing things like this, is peering into the early universe. Sure there are some quasars within a billion light years, but they're quite rare after 'the age of quasars'. Who knows, in the FAR future we may have another. SEA is easily my most anticipated space channel.
These are by far my favorite cosmology videos on RUclips. They’re extremely well put together, incredibly informative, and are perfect to throw on a playlist and fall asleep. Thanks for making these!
I love the journey in each video and how you touch on how our understanding of say, quasars, has evolved over time and where gaps still remain in our knowledge. @SEA nevers just says "this is a quaser, thank you for watching my Ted talk" and for that I am thankful.
I always watch your videos when I’m going to sleep, and they always end up keeping me up because I’m sat here so encapsulated by the stories you’re telling, thank you for always making the best videos SEA, I’m glad someone else loves space and cosmology as much as I do.
This is my third night of attempting to finish this video in bed. I always fall asleep after 10 minutes. And I mean that in the best way possible. The production quality of your videos is amazing and incredibly relaxing.
Thank you providing us with so much interesting space content, it's difficult to find a channel as specific as yours and I'm truly grateful for the content you provide.
This is one of the VERY few channels I think is highly professional and is a steal of content on here for free and who's videos not only I've seen all of but that I actually enjoy to re watch and really capture the essence of each topic and space in general.
Dude, your content is better produced than anything on History or PBS or any other platform. It’s amazing this is free! I’ve been a sub since your early days and your constantly improving! Cheers mate
I wish every class I had ever taken was like this. A huge amount of information, while at the same time easy enough for the non Astrophysicist to understand. This information really helps change one's perception of how important life and consciousness really is.
Your content is world class good. You should be an official spokesperson for the whole cosmology community. Your tone, diction and choice of words are a joy to learn from and the imagery is mesmorising. Don’t ever stop making these videos.
Why didn't I sub to this channel a long time ago? Some of the best astronomy/cosmology documentaries that have ever been made come from this channel. Top notch work.
I’ve always enjoyed SEA’s content and I like the narrators delivery. I’m at the most an amateur amateur astronomer. I understand just enough of all of this to know that I don’t understand most of it. But I’ll keep plugging away at it.
I really need to know what the thumbsdown people dislike about SEA's videos. Is it his attention to detail? His ability to express complex scientific data in a way that is more accessible? How about his spot on graphics? (I mean, they prompted ME to get SpaceEngine on Steam, but maybe you all don't like excellent graphics?) Or his on point music choices that compliment the graphics and excellent narration? I am truly puzzled.
This is by far the best astronomy content I have come across. I have heard I’d quasars many time but never understood the accretion disc. Brilliantly explained.
man! i think i can speak for everyone. we would love to have a new video every day or every week, but if we need to wait a month for this quality, we're glad to wait. now, speaking fro myself. your channel is the best on youtube! damn! every video is amazing! i've watched a lot of them multiple times in the last year, since im working from home. the graphic, the content, the voice, the jokes, everything is on point. thank you, man! honestly, thank you for your work! PS:i would kill to listen to a conversation between you and dr.brian cox!
SEA your videos are amazing I’ve listened to so many now and you just hit all the buttons bro. I love expanding my intellect and you help that process in this area of study. I appreciate you even tho u won’t se this😂👍
Astronomy used to be the most exciting for me until u realize almost everything about it is untouchable and will never be able to be used in any tangible way. Still mysterious though but damn why does it have to be so big
Hey man, I’ve been watching your content for a few months now and wanna say thank you. Especially for this video. I was about 5 years old when i first watched something on Discovery channel related to cosmos, it was About quasars. I was fascinated by it and was waiting for you to do video on this topic. Appreciated ❤️❤️ keep up the good work
This is an excellent video, packed with fascinating information about the history, nature, and distribution of quasars through time, how it has been put together, and some of the controversies and questions that remain. I have a question about the very distant quasars: to appear so bright across such a distance, do their jets have to be facing toward Earth? Surely a side or oblique view would be dimmer, especially if there is a deep torus. If they have to be facing to within a few degrees of line-of sight toward Earth, that implies that their number is much larger. If, on the other hand, they are that bright from most angles, then the emitting region is likely large (compared to the black hole, at least a few light weeks) and relatively exposed. What’s the consensus on this issue of the relation of quasar apparent brightness and orientation?
Ugh so true. It gives me hope when I look at SEA and other space-related videos. My problems, my anxieties and fears ultimately have just as much meaning as any other human on the planet.
Hi Sam, I'm happy to have stumbled upon your channel! I had worked as a physicist for a while before running away from academia, but never studied astronomy or cosmology, but has always been curious. I only took a semester of stellar physics, out of curiosity, but hardly remember a thing except the fact that I had taken it... :) Cosmology had hardly been even a thing when I was a grad 40 years ago, i.e. not something you'd seriously think of dedicating your scientific life to, but now-oh boy, I'm contemplating how much progress we've seen in the last 20 years alone! If you don't mind a couple notes: 03:30 It's probably worth noting that hot fully ionised plasma moving at huge velocities is full of local electrical currents, and the accretion disc should develop extremely complex self-sustaining electromagnetic fluxes in addition to the mechanical viscous fluid flows due to dynamics alone. At least qualitatively, it's certain that another class of rotating objects made of fully ionised gas, a.k.a. stars, do develop magnetic fields. Precisely modeling this stuff is a nearly intractable MHD problem, and the origin of AGN jets is a wide-open question, but it's hard to explain the jets-and especially their radio noisiness-by gas dynamics alone. 14:30 It's not exactly right to think that the Universe is expanding “in all places”. I wouldn't mind if my house expanded a bit, but then I'm thinking about my belly... It's true indeed that we don't _feel_ the expansion of space, but it could have been said more explicitly that we don't because our local space does not expand. The main thing that makes it so is the GR's background-freedom: it describes both the geometry of spacetime and the fluxes of stress-energy _within_ this spacetime. Whether a region of space is expanding or not is, in the end, defined by its energy contents, distribution and fluxes. Our Galaxy is indeed gravitationally bound, as is the Virgo cluster we're part of. The Virgo Supercluster may not be entirely bound, and this gives an approximate contemporary scale at which the Universe expands-or does not. It's hard to put a number on it, as the large-scale structure of the Universe is rather fibrous, and fluxes form multipoles, both apparently attracting and repulsing, but I don't think I'd be too much off calling an order of mag of 10⁶‒10⁷pc. Some of (not too regularly shaped) “cells” of this size are held from the expansion by gravitation, others are dominated by the repulsive Λ-term that we don't really have a clue about physical meaning of. (Personally, I find the catchy name for the repulsive “dark energy” a bit, uhm, repulsive; “Λ-term” is all we know what it, mathematically, is. Otherwise, _hic sunt dracones…_ 🙂)
Min 4:57 "take this deep photograph of space" is just mind-blowing awesome. The pace of this video and its music is just perfect, and I must have watched it at least a hundred times now
Excellent, comprehensive video with beautiful ilustriations and one of my best sources of information ! One thing is clear: After my reincarnation I want to be a quasar... In the last few months we've been hearing from some astrophysicists that we might be living in a black hole? - I don't think so, but black holes and their quasar variant are undoubtedly very important in the creation and ordering of the universe, and also fundamental as a source of light and energy!
I find myself feeling so small and insignificant when watching amazing videos as yours. It goes to show how insignificant we are in this universe. And how one star can outshine all of us In under one second.
I’m glad you found what you like doing and made it with the intention to put out what you like very much and not only are you very very informative and very unique but very nice to have a video along side a morning waking up or wanting just a chill good time
Don't get me wrong. But when some people say that they don't like physics but these youtube channels make them love it, I don't really understand how cause I always loved physics. But finally I understand them because I never really liked astronomy but this guy makes me love it.

@@kevinflaherty1 the letters usually represent what type of object it is and the numbers are just straight coordinates sometimes with extras like which telescope found it or the cluster its located in. I more referring to giving stuff a 'proper' name though. Observatories/telescopes work the same way (ELT literally stands for Extra Large Telescope)

This channel is incredible. Great and comprehensive info, no click-bait titles and not a single plead for likes or subs. The videos are practically animated white papers.
The best space channel! I look forward to each video and you can tell how much work he puts into each one and how much he loves the subject. 🌟 really amazing work
I love this channel. There's something philosophical and deep about the discussion of space here - it's unique stuff, not gimmicky, not too dumbed down and his voice is like a sage.
The Gamma Ray Burst Wall, Bootes Supervoid along with things like this are easily the most fascinating/horrifying things to think about in this universe. It's amazing to think about seeing things like this, is peering into the early universe. Sure there are some quasars within a billion light years, but they're quite rare after 'the age of quasars'. Who knows, in the FAR future we may have another.
SEA is easily my most anticipated space channel.
These are by far my favorite cosmology videos on RUclips. They’re extremely well put together, incredibly informative, and are perfect to throw on a playlist and fall asleep. Thanks for making these!
Literally, every upload is like a birthday present to me. Love your content and narration. Please keep it up.
I love the journey in each video and how you touch on how our understanding of say, quasars, has evolved over time and where gaps still remain in our knowledge. @SEA nevers just says "this is a quaser, thank you for watching my Ted talk" and for that I am thankful.
I always watch your videos when I’m going to sleep, and they always end up keeping me up because I’m sat here so encapsulated by the stories you’re telling, thank you for always making the best videos SEA, I’m glad someone else loves space and cosmology as much as I do.
Me too. Lol. Sometimes. 😅🗣🌌🪐🌞🌖😴😴
I like the pictures loo
This is my third night of attempting to finish this video in bed. I always fall asleep after 10 minutes. And I mean that in the best way possible. The production quality of your videos is amazing and incredibly relaxing.
Thank you providing us with so much interesting space content, it's difficult to find a channel as specific as yours and I'm truly grateful for the content you provide.
This is one of the VERY few channels I think is highly professional and is a steal of content on here for free and who's videos not only I've seen all of but that I actually enjoy to re watch and really capture the essence of each topic and space in general.
One of the few channels for which I genuinely get excited over new videos.
Likewise, I get a little "yay" in my head when a new one appears
You are massively underrated on here. Honestly you deserve millions of subs!! Your better than 99% of documentaries 👌 Love your work brother
still not as bright as when seeing your phone in the middle of the night.
SEA, you are a dream come true. Your genius work puts others to shame. Thank you for all that u do for us!!
Dude, your content is better produced than anything on History or PBS or any other platform. It’s amazing this is free! I’ve been a sub since your early days and your constantly improving! Cheers mate
I wish every class I had ever taken was like this. A huge amount of information, while at the same time easy enough for the non Astrophysicist to understand. This information really helps change one's perception of how important life and consciousness really is.
I love that the darkest thing in the universe is also the brightest thing in the universe.
Albino u miss me wow
Your content is world class good. You should be an official spokesperson for the whole cosmology community. Your tone, diction and choice of words are a joy to learn from and the imagery is mesmorising. Don’t ever stop making these videos.
Imagine living on a planet where light comes less from your sun and more from the black hole in the center of your galaxy
You don't have to imagine. You can experience it in space engine yourself, which is what he's using to get the footage. RUclips it
The Sun is humiliated enuf don't remind it.
Literal black hole sun. Soundgarden must have come from a quasar galaxy 😂
Why didn't I sub to this channel a long time ago? Some of the best astronomy/cosmology documentaries that have ever been made come from this channel. Top notch work.
We are just an *_atom in the universe_*
Even smaller than that, probably a quark, bc we don't know what's beyond the visible universe.
We ARE the universe. At a large enough scale you can think of it all as one ongoing process of which we are directly a (miniscule) part of
Yes we do....more universe
What are you talking about. I'm just answering the fuckin question to the video which choo choo asked
@@peace4myheart much much smaller than a quark... even to the observable universe
I’ve always enjoyed SEA’s content and I like the narrators delivery. I’m at the most an amateur amateur astronomer. I understand just enough of all of this to know that I don’t understand most of it. But I’ll keep plugging away at it.
Same brother. But its fascinating non the less.

I really need to know what the thumbsdown people dislike about SEA's videos. Is it his attention to detail? His ability to express complex scientific data in a way that is more accessible? How about his spot on graphics? (I mean, they prompted ME to get SpaceEngine on Steam, but maybe you all don't like excellent graphics?) Or his on point music choices that compliment the graphics and excellent narration?
I am truly puzzled.
This channel needs seriously more visibility, like why doesn't this have millions of views.
Not enough of us nerds around. Sadly, ignorance of science or science denialism seems to be more prevalent.
First new video since I subscribed a couple of weeks ago. Excited! Love your content.
This is by far the best astronomy content I have come across. I have heard I’d quasars many time but never understood the accretion disc. Brilliantly explained.
Love your content bro. I hope this message makes you smile like your content does for me
Love your videos. The best space/cosmology content on youtube period. I hope you could do a video explaining string theory too, that would be dope
“Yes, it really is called the huge large quasar group”🤣🤣
When SEA says "vast quantities".....it makes me really happy
"Something we shouldn't worry about in the Milky Way,"
Those sound suspiciously like famous last words to me. ;-)
man! i think i can speak for everyone. we would love to have a new video every day or every week, but if we need to wait a month for this quality, we're glad to wait.
now, speaking fro myself. your channel is the best on youtube! damn! every video is amazing! i've watched a lot of them multiple times in the last year, since im working from home. the graphic, the content, the voice, the jokes, everything is on point.
thank you, man! honestly, thank you for your work!
PS:i would kill to listen to a conversation between you and dr.brian cox!
What a lovely surprise. 😊 Thank you, as always, for your wonderfully written words, calming narration and brilliant delivery. Take care.
SEA your videos are amazing I’ve listened to so many now and you just hit all the buttons bro. I love expanding my intellect and you help that process in this area of study. I appreciate you even tho u won’t se this😂👍
Astronomy is the most exciting science, in my opinion.
Astronomy and microbiology for me! As above, so below.
especially when you are trying to sleep!
I'm a neuroscientist and even I agree with you!
Astronomy used to be the most exciting for me until u realize almost everything about it is untouchable and will never be able to be used in any tangible way. Still mysterious though but damn why does it have to be so big
@@henrycraig5952 That's exactly why it's so exciting. The fact that the universe is mysterious and colossal.
This guy totally rocks it. This and History of the Earth \ Universe are my go to channels. Keep it coming dude.
"Huge Large Quasar Group" is the best example of how bad scientists are at naming things that I've ever seen
Hey man, I’ve been watching your content for a few months now and wanna say thank you. Especially for this video. I was about 5 years old when i first watched something on Discovery channel related to cosmos, it was About quasars. I was fascinated by it and was waiting for you to do video on this topic. Appreciated ❤️❤️ keep up the good work
Damn I love this channel!! This is peace and tranquility and knowledge all in the same place.
👍😂
you have outdone yourself again...thank you for educating us!! 💫 quasars are so epic
This is an excellent video, packed with fascinating information about the history, nature, and distribution of quasars through time, how it has been put together, and some of the controversies and questions that remain.
I have a question about the very distant quasars: to appear so bright across such a distance, do their jets have to be facing toward Earth? Surely a side or oblique view would be dimmer, especially if there is a deep torus. If they have to be facing to within a few degrees of line-of sight toward Earth, that implies that their number is much larger. If, on the other hand, they are that bright from most angles, then the emitting region is likely large (compared to the black hole, at least a few light weeks) and relatively exposed. What’s the consensus on this issue of the relation of quasar apparent brightness and orientation?
Of the hundred channels I am subscribed to, your videos are the ones I am most excited to see pop up
Love your vids bro, please keep them coming! 😎
Another wonderous piece of art. Thank you SEA for bringing such brilliant content, I look forward to what's coming next.
whenever I'm feeling like shit, a gentle reminder of how small we all are is helpful. There is no better place for that reminder than SEA
Ugh so true. It gives me hope when I look at SEA and other space-related videos. My problems, my anxieties and fears ultimately have just as much meaning as any other human on the planet.
Hi Sam, I'm happy to have stumbled upon your channel! I had worked as a physicist for a while before running away from academia, but never studied astronomy or cosmology, but has always been curious. I only took a semester of stellar physics, out of curiosity, but hardly remember a thing except the fact that I had taken it... :) Cosmology had hardly been even a thing when I was a grad 40 years ago, i.e. not something you'd seriously think of dedicating your scientific life to, but now-oh boy, I'm contemplating how much progress we've seen in the last 20 years alone!
If you don't mind a couple notes:
03:30 It's probably worth noting that hot fully ionised plasma moving at huge velocities is full of local electrical currents, and the accretion disc should develop extremely complex self-sustaining electromagnetic fluxes in addition to the mechanical viscous fluid flows due to dynamics alone. At least qualitatively, it's certain that another class of rotating objects made of fully ionised gas, a.k.a. stars, do develop magnetic fields. Precisely modeling this stuff is a nearly intractable MHD problem, and the origin of AGN jets is a wide-open question, but it's hard to explain the jets-and especially their radio noisiness-by gas dynamics alone.
14:30 It's not exactly right to think that the Universe is expanding “in all places”. I wouldn't mind if my house expanded a bit, but then I'm thinking about my belly... It's true indeed that we don't _feel_ the expansion of space, but it could have been said more explicitly that we don't because our local space does not expand. The main thing that makes it so is the GR's background-freedom: it describes both the geometry of spacetime and the fluxes of stress-energy _within_ this spacetime. Whether a region of space is expanding or not is, in the end, defined by its energy contents, distribution and fluxes. Our Galaxy is indeed gravitationally bound, as is the Virgo cluster we're part of. The Virgo Supercluster may not be entirely bound, and this gives an approximate contemporary scale at which the Universe expands-or does not. It's hard to put a number on it, as the large-scale structure of the Universe is rather fibrous, and fluxes form multipoles, both apparently attracting and repulsing, but I don't think I'd be too much off calling an order of mag of 10⁶‒10⁷pc. Some of (not too regularly shaped) “cells” of this size are held from the expansion by gravitation, others are dominated by the repulsive Λ-term that we don't really have a clue about physical meaning of. (Personally, I find the catchy name for the repulsive “dark energy” a bit, uhm, repulsive; “Λ-term” is all we know what it, mathematically, is. Otherwise, _hic sunt dracones…_ 🙂)
Excellent comment ! Glad to see people like you exist.
You're the only youtuber I turn my ad blocker off for lol
Min 4:57 "take this deep photograph of space" is just mind-blowing awesome. The pace of this video and its music is just perfect, and I must have watched it at least a hundred times now
I'm a simple man. I see a SEA upload, I like it.
I'm a surprise person. I see a joke used a million times and I laugh out loud
Excellent, comprehensive video with beautiful ilustriations and one of my best sources of information ! One thing is clear: After my reincarnation I want to be a quasar...
In the last few months we've been hearing from some astrophysicists that we might be living in a black hole? - I don't think so, but black holes and their quasar variant are undoubtedly very important in the creation and ordering of the universe, and also fundamental as a source of light and energy!
God i love this channel so much. it really deserves more attention
I'm glad I found it
I find myself feeling so small and insignificant when watching amazing videos as yours. It goes to show how insignificant we are in this universe. And how one star can outshine all of us In under one second.

Excellent video!
Best explanation of red shift I've heard. I understand it better now. Im going to subscribe. I look forward to your take on JWST's future findings.
SEA easily deserves more than 1-2 million subscribers... At least. I've watched all of your videos, again and again. Love from India.
With this quality I'm actually surprised that you don't have at least a million subscribers, amazing video as always
I really love watching all your videos. They're so informative and relaxing!
Absolutely bomb videos lately. Extremely impressed. Was a very fun watch. Thx @SEA
Bro well done!! You always have really high quality contents, keep it up !
Fantastic video! I have recently discovered this channel and the quality is brilliant!
It's amazing how much he's grown past his already great GD content that he started out creating.
Completely captivating, beautifully assembled - I am inspired. Thank you.
Thank you for making my night awesome
The quality of these videos are better than PBS specials when I was a kid... good job
Love this video. It shows how the “Big Bang” theory limits are ability to realize the infinite.
Man your video's are the best!
Thanks for your hard work we can all see and enjoy it.
I love your content!! I can't believe you out this stuff up on RUclips for free hahaha
Don't get me wrong. But when some people say that they don't like physics but these youtube channels make them love it, I don't really understand how cause I always loved physics.
But finally I understand them because I never really liked astronomy but this guy makes me love it.
Extremely underrated channel
Spread the word.
It's always a good day when SEA has a new space video up
