    I absolutely love these videos. It's both expertly explained and made visually understandable. As someone with autism who loves learning these videos are my favorite. A cool video idea I thought of is talking about the 10 and 12 dimension theories. It's one of my favorite subjects and has cool math and history behind it.

    Great video and explanation! My only note is that scanning horizontally across the target (e.g. at 6:40) should produce one horizonal line of pixels, without the vertical component of the image. There would need to be multiple passes at different elevations combined to make a 2d image.

    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.

    Man, thank you for making these videos. I’ve been obsessed with astronomy and Astro physics my entire life but you somehow have a way of explaining things that helps me to understand better than ever. I’ve thought about that image of a black hole from interstellar for years now trying to figure out why it looked the way it did. I knew it had a lot to do with the mass and warping of space time but this video is so informative. Thanks again for the great content.

  • Your grandma blew me about

    That we have managed to aggregate instruments across the earth’s surface to achieve once impossible resolution is a real triumph for science, made possible by the use of GPS timing and location cues embedded in computer algorithms processing results gathered around the globe. Despite my understanding it, it’s a stunning accomplishment.
    Still, the image of stars racing around a black hole is the most jaw-dropping thing I have ever personally seen. I have spent an embarrassing amount of time watching that loop, considering the implausibility of ‘being there’.

  • Quintin Scheffer
    Quintin Scheffer 2 days ago +1

    Not sure where to ask this question, but could you explore or explain in layman's terms the relationship between black holes and light? Light cannot escape a black hole as I understand, so does that mean that the force "pulling" in a black hole is at a speed greater than the speed of light?

    • RiteMo LawBks
      RiteMo LawBks Day ago +2

      That is the simple explanation of it. The dark part of the black holes is where the escape velocity is greater than the speed of light.

  • Alexander Dubstepcek

    i'm not sure what amazes me more, the dimensions of black holes or how they play with reality (or rather our perception of reality). what i know for sure is, we need more videos on them from Veritasium.

    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.

    The explanation works for what we saw looking at the M87 image. (actually this explanation was the first video I saw from Veritasium and I never missed any since then). However, the image of Sagittarius A* contains _three_ bright spots. I cannot interpret that - the matter can't move towards to us at all three sides. I thought directly about it when I first saw the image. And I was excited to hear an explanation to that in this new video. Instead, we got footage from the old video.:-(
    Anybody can explain why there are three bright spots at the latest image?

      @Sisaska You can definitely believe in God as a scientist. All that a scientist can interfere with is the creation, if you want to call it that way. We can't use science to proof or disprove God. But I have a problem when religion contradicts science. That's like saying God is misleading us by putting us in a universe with all these rules, where we can predict outcomes correct and create a consistent image of the universe without contradictions, but the bible says something else which contradicts those rules.
      How about saying that nothing existed yesterday and this morning God created the entire universe with you and me and planted memories of our past life straight into our brains. God could certainly do it, and it is not less logical that saying the dinosaurs where flushed away by water and somehow became stone just 4400 years ago.

      @Brian Hale To see a star ignite you would need to know where to look, and when to look. The number of stars in existence is not the number of stars igniting, the sky is incredibly large. And it is not as fast a process as you might think, as it is not like the explosion of an H-bomb (or it would rip the star to shreds). You could look at the Wikipedia page to get a better grasp of how a star is "born", and how hard it is to actually "see" it, than come back and refine your argument.

    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.

      @Allan RoserLots of “theories” were just theories until proven true. Black holes were once a theory too. Then we discovered them. Now we even have images of two black holes.

But keep having a misunderstanding of what science is, you wouldn’t be smart enough to work in any scientific field so it doesn’t matter whether you understand what science is and what it isn’t anyways.

I sent it to this guy on fiver and he was able to render it and it turns out was an exact copy of an irregular galaxy they really do some amazing work.
      I find it really interesting how I took photos of my house over a course of several years. In some pictures my windows are the size of my door and then they look as they should in other pictures. I discovered this phenomenon when looking at pictures of the earth though the years and noticed the continents are all different sizes in each picture. Space is some really crazy stuff, one day I hope we can re-build the telemetry data on how to leave low earth orbit and go to the moon. One day computers will be as good as they were back in 1969 and they will be capable of doing such things.

      @streuthmonkey1 There was no image taken by the telescopes, they took light phase and timestamp data. That data was used to construct an image after the fact. The number of pixels in that final image can be however many or as few as you want, and it doesn't change the quality of the input data.
      What exactly are you referring to?

    From the interferance pattern mapping composing a picture (looks like a Fourier transformation, but applied to an image)
    Up to the description of the image, and how the warping in space affects what you see
    simply gorgeus

  • Денис Сиренко

    Thanks Derek! But it still remains unclear to me: if the accretion disk can be directed towards us, then why can't we see its leading edge crossing the central region of the image? After all, some of the rays from it are not directed in orbit around the black hole, but directly towards us, and, in theory, should not change their trajectory (well, or almost).

      @trbz_ We are looking at both poles. Our black hole's accretion disk isn't inline with the galactic plane.

    • Денис Сиренко
      Денис Сиренко 7 days ago +1

      @trbz_, It does not have to be thin, only if disc crosses black hole exactly in the middle, which is very unlikely. Unless, of course, there is some correlation between the planes of rotation of the accretion disk and the entire Milky Way, as a result of which we automatically look at the disk exactly from the side.

    • trbz_
      trbz_ 7 days ago +1

      For the M87 black hole, it ended up being that we are looking towards it from a pole, rather than from the side. For Sagittarius A*, the resolution is too low to be able to make out the thin bisecting line of the disk.

    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!

    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.

      @Sha Smi Thank you.
      I just want to say that if you're under 50, I don't think it's too late to make some sort of career in science if you really want to. There were quite a few students in their 30s and 40s on my undergrad physics course.
      I was also on that path of drugs, alcohol and partying, at a very young age. Discovering a love of science was one of the things that really pulled me away from that. It made me feel like I was an outsider compared to the crowd I was in with, so one day I just cut them off. I was a bit of a recluse for a few years after, but it was good for me in the long-run.
      I've been going to gigs regularly since I was 16 though, I don't think that's hindered my focus at all over the years.
