Just Some Guy without a Mustache Just Some Guy without a Mustache 2 days ago Absolutely jaw dropping how inconceivably huge these supermassive black holes are. I always love it when Veritasium delves into the topic of space. 9K Veritasium hecker hecker 1 day ago More space please. This was absolutely amazing. Thanks. 1.3K Xavier Xavier 1 day ago The explanation and practical demonstration of the way the "image of a black hole" is formed, starting at 10:41, is really marvelous! Great job, Veritasium! I really love that very hands-on prop he used. 416 Lonely Sandwich Lonely Sandwich 9 hours ago The way you describe the 'Earth sized" telescope at 10 minutes was so perfect. 47 R T R T 1 day ago I love how he explained it that even a person who has no understanding of this subject can clearly comprehend the process of creating an image of the black hole! 346 Ziyuan Ma Ziyuan Ma 1 day ago Imagine being that person who’s going on a plane carrying the hard drive of one of the telescopes, a piece of a puzzle that is truly precious beyond measure 131 Advesh Darvekar Advesh Darvekar 2 days ago This is hands down the best explanation of a black hole I've ever heard. 3K Veritasium emarsk emarsk 1 day ago I find the time lapse of the stars orbiting extremely fascinating. One thing it's always missing when I see it in videos like this, is the time scale. It's easily googleable (about 20 years), but I'd like to see it in a footnote. 107 HighlandPhoenix HighlandPhoenix 1 day ago 1:49 how have I never seen those star movements before?! That is incredible and should go hand-in-hand with the actual image of the Blackhole! Thanks for the video. 85 Anoop Rawat Anoop Rawat 1 day ago (edited) Absolutely amazing stuff… “space + veritasium” a perfect combo for all curious folks. Bring more space stuff please. 6 Yecto Yecto 17 hours ago This guy needs some kind of highest award for teaching humanity in such a easier way for us to understand This guy never disappoints 3 Ray Templo Ray Templo 1 day ago Really fascinating how the image was computed and what an excellent way of explaining it! 4 Suchithra S Suchithra S 4 hours ago The world needs teachers like him! Watched many videos about Sgr A* imaging and none of them explained it as clearly and simple as he did! I am marking this video as my black hole reference. 1 HARSH RAJ HARSH RAJ 1 day ago (edited) I really had that "aha!" moment when he explained how the accretion disk looks the way it was shown in the movie Interstellar, Veritasium never disappoints! 40 Biraj Guha Biraj Guha 16 hours ago This is the crown jewel of Veritasium videos. it answered several questions at once in a visually stunning manner. Spectacular black holes deserve spectacular videos. 3 MrMattie725 MrMattie725 2 days ago The craziest thing to me is that these images just confirm our theories. We had visuals of black holes purely based on the Maths. A random guy on the street could have a decent image of a black hole because a movie did the effort to represent it correctly (minus the lighter and darker parts). And only a few years later, we manage to take a picture which just happens to be exactly what we expected. 1K Len Humbird Len Humbird 1 day ago I agree with Aieou: The explanation of imaging a black hole was profoundly effective! Worth another watch. 38 Paul Noble Paul Noble 1 day ago I really shouldn't watch this kind of thing at this time of the day here in the UK. The amount of detail that can be resolved from a radio source with the right equipment and the brains to power it is absolutely amazing. Fantastic video, as always. 1 MeDoMeer MeDoMeer 22 hours ago As an astrophysics student, I am very happy that this video exists. The explanation is spot on, and I learnt a thing or two as well! I learn a lot about the fringe patterns and interferometry this year, and it really was a great visualization! Thanks :) 1 Arijit Roy Chowdhury Arijit Roy Chowdhury 3 hours ago Hey Veritasium, I have a question🙋. Given that the space is so big and these images are so huge, how does scientists decide where to look? Is there a pattern that they follow? Or is it just random? 1 Aieou Savren Aieou Savren 2 days ago The explanation and practical demonstration of the way the "image of a black hole" is formed, starting at 10:41, is really marvelous! Great job, Veritasium! I really love that very hands-on prop he used. 737 Zariah Aspen Zariah Aspen 4 hours ago I love how he explained it that even a person who has no understanding of this subject can clearly comprehend the process of creating an image of the black hole! 1 Clara -My New SAX Video Vlog Clara -My New SAX Video Vlog 1 day ago 1:49 how have I never seen those star movements before?!

Thanks for the video. 1 SamoaFA SamoaFA 15 hours ago I never leave without learning something of subject presented. Your explanation are easy to understand and enjoyable to watch. In particular I enjoy your space and oceans vignettes. With said your channel is one of my favorites. Thank you. Looking forward to future shows. 1 Naresh Cherukuri Naresh Cherukuri 14 hours ago Your dedication and interest to make us understand the concepts are extremely adorable. This is the best explanation I have ever seen on the internet. 1 The Boots The Boots 2 days ago I've gotta hand it to you-- this was one of the most easily understandable explanations of why we see what we see in these pictures I've ever experienced. Absolutely outstanding work of science communication that makes incredibly complex material understandable without dumbing anything down. 718 Blokprintz Print with Paint! Blokprintz Print with Paint! 3 hours ago ‘Light has no mass’. Incredible. The concepts in this film are amazing, and so beautifully and clearly explained. 1 Zariah Aspen Zariah Aspen 4 hours ago I agree with Aieou: The explanation of imaging a black hole was profoundly effective! Worth another watch. GWNJerry GWNJerry 1 day ago Wow, I've been a subscriber for about 10 years and it keeps amazing me how much the quality of your videos keep increasing. From asking people on the streets about misconceptions to videos explaining the pictures of black holes. You have inspired me to study engineering and are keeping me interested in science with every video. Please continue your passion, you are truly endlessly valuable in the youtube community! 1 Lino Foodtech Lino Foodtech 1 day ago Never ever attended such a complex topic class explained in such a clear way. Amazing 6 Achintya SG Achintya SG 2 days ago 10:31 the way the black hole's picture appears from just black and white lines, is truly amazing.. hats off to the people who took this amazing image of our closest supermassive black hole 613 Jason Samia Jason Samia 41 minutes ago (edited) great explanation! I love how it makes it easy for regular people like myself to understand these things ;D Question: If the light and debris at 2.6 - 3.0 rs is a sphere going around the black hole, then why is the light represented as a flat donat pancake? If it's a sphere, then shouldn't we see a bright round glowing ball? We wouldn't see anything black at all because there's SPHERE of light surrounding the black hole... Sorry, I might be missing something... just a thought... thanks 1 Paul Donlin Paul Donlin 2 days ago I've gotta say that your "what does a black hole look like?" explanation is by far the best. I re-watch that video with some frequency while trying to explain black holes. They're basically a spherical "fun-house" where light does all kinds of wacky things. Even the paper written by the visual effects developers for Interstellar leaves a lot on the table in explaining what these things would look like and you do such a great job. 763 Matthew Ledet Matthew Ledet 1 day ago This is amazing!!! Space absolutely blows my mind and I'm super grateful there are people out there who are smart enough to image it and explain it. Thank you for explaining that so well. It was fascinating. 1 Haliaeetus leucocephalus Haliaeetus leucocephalus 1 day ago Hey thanks for that awesome explanation! I had long wondered about how scientists arrived at the theoretical images we have. Your old school approach to explaining it is perfect. 1 SHOPETSY SHOPETSY 1 day ago I love having complex ideas explained in a non-patronising, yet really interesting way. Definitely had lots of “Ah-Ha!” Moments 1 Aleis in Wndrlen Aleis in Wndrlen 2 days ago In 2019 we had our first ever look at a black hole, pretty much confirming Einstein's theory of relativity, made over 100 years ago. And 3 years later, we finally captured the image of our galaxy's centre, which was for the longest time thought to be near impossible due to the many space debris and dust clouds covering it. It's truly fascinating to see how far our technology has improved in just a span of a few years. 589 History Dose History Dose 2 days ago Somehow “supermassive” still sounds like an understatement. I vote for “SuperDuperMassive” 225 Zariah Aspen Zariah Aspen 3 hours ago I love how he explained it that even a person who has no understanding of this subject can clearly comprehend the process of creating an image of the black hole! Dominic LoBue Dominic LoBue 2 days ago As technically impressive as these renderings are, the clip showing those stars zooming around apparently nothing is what blows my mind. I feel like I could watch that for hours and still be fascinated... 581 Armaan Sharma Armaan Sharma 1 day ago These are actually amazing, they way Veritasium delivers the information is so easy to understand, thanks 1 marcoscolga24 marcoscolga24 2 days ago (edited) For anyone who complains about black hole images being blurry: 0:28 On a more serious note, seeing the image come together at 10:30 literally dropped my jaw. It's so incredible watching seemingly unrelated patterns coalesce into such an incredible image. 775 SolarisJade SolarisJade 1 hour ago His visual was actually really helpful in explaining the bending of the light, very nice video!! Im super interested in black holes and all kinds of space stuff so this was really nice to see such a good explanation!! Theo Laanstra Theo Laanstra 1 day ago Wow, this was really good. My favourite part was when you demonstrated the way you can see the top and bottom of the far side of the accretion disk, that was mind-bending but it still made sense! Great work! TimeBucks TimeBucks 1 day ago What a great explanation 489 Nicholas Vasconcellos Nicholas Vasconcellos 1 day ago Honestly the amount of seemingly complex information conveyed in these videos in such an intuitive way is incredible to me! Always look forward to your uploads man! Kevin Godfrey Kevin Godfrey 2 days ago I'm not even gonna pretend otherwise, the arts and crafts really helped me get a true grasp of what you were describing. Perfectly demonstrated 260 Kedar Sharma Kedar Sharma 18 hours ago Hey Derek. First of all, love all ur videos. They make me love science so much more than school has ever. Also, I have a small doubt whether light gets bent due to strong magnetic fields or clusters of ionised gas in space because light itself is an oscillation of electric and magnetic fields? Liza_Official Liza_Official 1 day ago The fact that I could understand everything you said, speaks volumes about your ability to teach. Thank you for making me feel smarter than I actually am! Shantanu Paul Shantanu Paul 2 days ago Just a few years ago, when I was in school, we learnt that the centre of our galaxy 'might' contain a black hole and now we have an image of it. The speed of scientific progress is just astonishing. 235 Scott Robinson Scott Robinson 2 days ago I loved the revisit to your old explanation from the M87* image. Still the clearest and most intuitive explanation I've seen, and the one I always mimic when trying to explain it to friends and family members. I've been watching your videos for over 10 years, since I was about 13 years old. I'm 24 now, working on my PhD in Astrophysics. Even with the knowledge and experience I've gained from my education, I still find that your explanations are usually robust, intuitive and very visually appealing. You're an inspiration Derek. I will be sure to thank you in the acknowledgements of my thesis when the time comes, because I don't think I'd be where I am without your videos, and the videos from other science communicators. 239 Aheront Aheront 10 hours ago Imagine being that person who’s going on a plane carrying the hard drive of one of the telescopes, a piece of a puzzle that is truly precious beyond measure Liza_Official Liza_Official 1 day ago The fact that I could understand everything you said, speaks volumes about your ability to teach. Thank you for making me feel smarter than I actually am! Clancy James Clancy James 2 days ago As a radio astronomer myself, I've got to say that your explanation of interferometry was amazing. Might point some of my students towards it! 190 Abhishek Pandya Abhishek Pandya 2 hours ago Hi, amazing explanation of how these images are captured and ofcouse love the way you have explained why the black holes look like the way it looks... I have some questions, not sure if this is right place to ask those. Questions: 1. Is accretion disk always flat in one plane? Like ring of Saturn? If so what’s the reason? 2. Is black hole responsible for motion of all the stars around the centre of galaxy? And in case if spiral galaxy, is this motion due to black hole is responsible for the spiral shape? Hjjja :) Hjjja :) 1 day ago It's amazing how far we humans have come. From cavemen, to the most dominant species. Beautiful. Eduard Eduard 13 hours ago Great explanation! Especially the part of how the radio telescopes exactly work and how they are combined together, because that was the thing I still did not fully know. seberoth inkinde seberoth inkinde 8 hours ago Thank you for your excellent discussion of resolution. Resolution and accuracy are very commonly used and very important scientific terms that deserve such explanation. Tiago Dutra Tiago Dutra 1 day ago SCIENCE! That was a great explanation, just like the masters did. Stephen Hawking and Carl Sagan were the best at explaining these crazy concepts, and so are you. Thanks so much, man, that was FANTASTIC. Alex the Average Alex the Average 2 days ago When I was a kid I was OBSESSED with space and especially black holes! I remember my junior high science teacher saying they were only "theoretically there" but probably were, and that bummed me out for some reason. He said though we likely wouldn't know in my lifetime if they were surely there let alone what they look like. Yet here we are and I'm absolutely blown away!! I love being alive during a time when more and more amazing steps are being taken in space exploration. I'm 30 now and I can only imagine what things will be like in another 30 years! 450 Colton Fairley Colton Fairley 23 hours ago I wish you had talked more about the features in the picture itself, for example the three bright spots. I assume one of those is where we are seeing relativistic beaming. However the disk looks lumpy and I'm curious what that might hint at. Archie Cocke Archie Cocke 1 day ago Your presentation is just as impressive as the subject matter. You do amazing work! Phizicks Phizicks 1 day ago I love that explanation and break down of each part of the visualization of the black hole and how/why it does that effect. makes perfect sense when explained that way. jocked07 jocked07 1 day ago what an amazing explanation of measuring black holes! question: what happens to light/matter between 2.6 and 3.0 radius from the black hole? Kernicterus Kernicterus 15 hours ago Your explanation of 'what we are seeing' is so cool and easy to understand, and as sure as eggs are eggs, I forget it as soon as I start watching FailArmy. I wish I could remember, I wish I had your talent. Keep up the excellent work. panner11 panner11 2 days ago The continuous zoom-in from a relatively wide view of the night sky all the way to the stars surrounding the black hole really puts things into perspective. 227 [ N A T A L I]-T[A]P Me!! to Have [𝐒]𝐄𝐗 [ N A T A L I]-T[A]P Me!! to Have [𝐒]𝐄𝐗 23 hours ago Absolutely jaw dropping how inconceivably huge these supermassive black holes are. I always love it when Veritasium delves into the topic of space. Stephen Hollstrom Stephen Hollstrom 11 hours ago Thanks for the video! The hot plasma surrounding the Black Hole does it "move" from our perspective? Or is it "frozen" because of extreme time dilation so close to a super massive Black Hole? Vincent M Manias Vincent M Manias 2 days ago I remember staring at that updated, swirling "Polarized" black hole image that was released a few months after the famous, blurry one, and trying to wrap my mind around how polarized lenses only take in focused light beams which pointed directly at you, which means the angle information from the image was, by definition, perfectly straight, perfectly direct, and perfectly focused. And yet, that polarized image of a black hole shows deep, beautiful, pronounced swirls of light spiraling a void. With little knowledge of physics, I just kept staring at it until it finally clicked that the light wasn't from the black hole, it was from the stars behind or around the black hole, and that their light WAS moving in a singular, focused direction - I WAS looking at a perfectly straight line - that's just how severely time and space were bending along that "Straight" path. That was one of the first times I felt like I could finally see and visualize relativity and that fabric of Spacetime I've heard so much about. 391 Moore Doing Moore Doing 1 day ago I love this channel so much! Wish teachers could make this channel part of their regular lesson plan. Trepidati0n Trepidati0n 1 day ago Curved space time is just so simple yet because of our viewpoint of the universe makes it nearly impossible for most to grasp intuitively. Every time this is explained my brain breaks because I get it but I cannot process it. Just amazing. Random Dude Random Dude 1 day ago (edited) Absolutely loved the part where I saw the interstellar black hole coming. I was seriously shook. Damn well done veritasium you never fail to explain these things to us clueless viewers❣️ 24 Nike Mwas Nike Mwas 1 day ago You are a very good teacher. Especially for slow learners. I now feel like a qualified theoritical physicist 😇 Frederick Obando Frederick Obando 1 day ago This was so well explained! Awesome, man! 1 Max Gotts Max Gotts 2 days ago I've taken two astrophysics courses at Princeton that have covered this topic. I've never got this much information on how adding the fringes actually works… VLBI is so cool 68 Helmut and Moshe Helmut and Moshe 16 hours ago (edited) It's important to mention that the "movie" of the stars orbiting our central black hole is time-lapse footage spanning nearly 20 years. I showed this to someone unfamiliar with astronomy and physics and the first thing they said is "the stars move that fast?!" - thinking that it was somehow real time footage. Yuya Plays Yuya Plays 21 hours ago Imagine how much more information we could get if we also had some regular and radio telescopes on the moon where there would be no more atmospheric interference and we could build them larger with the much lower gravity. KantanLabs KantanLabs 1 day ago Extremely clear and surprisingly detailed. Best didactic job on the web ! nen ben nen ben 10 hours ago (edited) The infinite images of shadows remind me of harmonic series I love the new data we've been getting just off of these two images we have. I've already seen you and another education communicator YouTuber giving some slightly newer insights and details of black hole imagery and physics Mystixor Mystixor 2 days ago Reading "We photographed the Milky Way's black hole for the first time" seems like a big deal, but really it has little immediate meaning. You showing how it's done, what it takes, and what it means is just great. Also, it's awesome that you prepared this prior to the press release so it's still relevant when people find your video. Thanks! 248 Neo Neo 1 day ago The funny thing for me about this video is, when the first event horizon pics came out, I searched for it and thats where I saw Veritasium for the first time and after seeing Derek explaining, I subbed right after the video. And today another jawdropping video 1 ErCavaliereNero ErCavaliereNero 13 hours ago The capacity of explanation of this channel is mind blowing.

Zariah Aspen Zariah Aspen 4 hours ago Imagine being that person who’s going on a plane carrying the hard drive of one of the telescopes, a piece of a puzzle that is truly precious beyond measure 1 norcalniner norcalniner 4 hours ago Great information and it makes this image even more impressive. Will images from the James webb telescope be more clear? Or is the telescope still too small? Steve Boyd Steve Boyd 1 day ago I actually understood about 12% of that - which means you did an AMAZING job of explaining it! Gabriel Iury Gabriel Iury 1 day ago Is it normal to get wattery eyes and increased heart beats seeing this visual black hole explanation? Amazing. Great job. Would recommend this video to every one who wants to understand black holes. Ochosi Onovevia Ochosi Onovevia 2 days ago I remember seeing the "Interstellar" in IMAX and couldn't comprehend the physics going on with the image. Your description towards the end of the video blew my mind as to how light bends around the black hole... Also a star is going ~8% the speed of light around Sagittarius A*, wouldn't that star system feel time slowing/speed up in comparison to the space around it due to the relativistic speed its going? Keep up the amazing videos man! 118 Tim Sexton Tim Sexton 1 day ago This fantastic video is explained in such a way that best suits my taste, which is the reason I watched it four times - at normal speed. In 2019, I read a detailed paperback magazine article that featured the M87 SMBH image. While the article was a long read and explained many details surrounding the Earth diameter virtual radio telescope, the multiple image stacking & final image generation, I filled some additional holes & details from your video not absorbed or recalled from the magazine article. Congrats on the video & great job on the production. YT's uncle AL is my restaurant chef who understands my tastes & biases with ever increasing accuracy. Sustained thought on that matter becomes creepy, yet amusing. JAJ 552 JAJ 552 1 day ago That physical demo of the actual structure of the black hole morphing into how it appears to us is so genius Burger Joint City Burger Joint City 21 hours ago The explanation was simply and yet brilliantly put forth! The reason why accretion disk forms a halo around the black hole and the visible thin line around the shadow itself are mind-boggling. Thank you Veritasium!😄 Two quick queries: Why is no light visible between 2.6 and 3 Schwarzchild radii? How is the composite image formed using radio waves coloured to yellow-white? T Sudhakar Patra T Sudhakar Patra 1 day ago (edited) What a crazy detailed explanation. Kudos to Veritasium! Really fascinating. But sad that i am able to absorb some percentage of the explanation as i am bad in physics. If i had studied well in school in i would have understood this much better. this explains we humans are nothing just a tiny part of this whole universe. Sudip Kr Sudip Kr 1 day ago Amazing presentation. What we know so far about our universe is just the tip of an iceberg.

However, this means its ring structure changes 1000 times faster, so this photo is technically far more impressive. Aislinn Ariadne Aislinn Ariadne 2 days ago That was really well done. I also loved the touch as why "Interstellar", was the most accurate representation of what would be seen. 110 Mark Dowse Mark Dowse 17 hours ago The irony of 'seeing' something that can't be seen and that is also so massive that stars orbit it quickly and yet could be treated as it it were microscopic is brobdingnagian, indeed ! 😲 Truly superb work by the scientists involved. Mind blowing. Technical and creative. A great explanation of how the black hole deals with EMR, sir! 👍 M 🦘🏏😎 allyourcode allyourcode 1 day ago It is crazy to me that they can record the data with such precision. 1 femtosecond is one millionth of a nanosecond, which is approximately the time it takes your CPU to complete one cycle. In other words, the sensors are running 1 million times faster than a computer (of course, they have many computers to do the recording). Then, you have the problem of trying to line up the data from different sources. It's one thing to locally run your sensor at 1 million GHz. It's another to figure out how the data from your sensor lines up with data from somebody else's sensor, which is exactly the "secret sauce" that makes the Event Horizon Telescope possible.

Love your content Elijah Love Elijah Love 18 hours ago 2:00 that's really similar to a flickering I recently caught of a star (?). It was very bright compared to anything else in the sky. Of all my stargazing I haven't actually seen a star this bright and active; I'm sure it wasn't a planet. Captured it over the course of a few months but it's out of view now. Very curious about it.
