    This was so rewarding to watch and fascinating to learn how far we’ve come in proving black holes exist. In my college astronomy texts from just two decades ago it was all still considered just theoretical. Thanks Veritasium!

    • scowie
      scowie Před 8 dny

      We haven't proven that black holes (as described by General Relativity) exist. The fact that these stars orbiting Sagittarius A* display no gravitational lensing effects whatsoever goes to show that the GR explanation of gravity is false - gravity is not the bending of spacetime at all. The path of light is unaffected by gravity. Gravitational lensing is a myth. All the observations that are claimed to be examples of gravitational lensing are really just good old refractional lensing in the density gradient of a gas cloud or an atmosphere.

  • 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).

    • Денис Сиренко
      Денис Сиренко Před 4 dny +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_ Před 4 dny +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.

    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.

  • MrMattie725
    MrMattie725 Před 13 dny +2736

    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.

    • jorriffhdhtrsegg

    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’.

    The best part of this video is that Derek looks extremely happy and excited when he explains the image with his cardboard model... This is why I love people like Derek Muller, Physics Girl, Michael Stevens - they are just soooo happy and enthusiastic to teach us such complicated topics in a simple yet profound manner. To me, people like these are not in anyway inferior to those who look up at the sky and solve the mysteries of the Universe.

    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.

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.

    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. It’s looking worse and worse for you buddy. 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.

  • Dr. Dhruvrajsinh Jadeja

    Just amazing!! This cleared my most puzzled question regarding telescopes that if space telescopes actually works like normal telescopes then we might be seeing in the past as light takes several years to reach earth!!! For example if planet is 500 lightyears away it takes 500 years to reach the image of the planet to reach earth but in forms of wave it is much simpler because to make the telescope that can focus the light from this distance is physically impossible but focusing waves is different thing.
    But this video actually makes me wonder what happens to waves that is around the black hole please answer my question anyone.

    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

      we see "black" because within that radius, light cannot escape. no light = darkness. So we are only seeing the light that manages to escape the event horizon. does that make sense?

      @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.

    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.

      Helmut and Moshe Před 7 dny +5

      @Drinkyoghurt Relativistic time dilation on any of those stars in the time lapse would not be that significant - they are too far away for that. The closest approach for any of them has been about 13 billion km or about twice the distance from earth to Pluto - they would need to be about 50 - 100 times closer for the dilation to be very significant. The other thing to consider is that (much like in the movie Interstellar) for anyone close enough to experience significant time dilation, they would not feel anything different - their own time passage would appear perfectly normal to THEM. However, if they were to observe people further away from the black hole - they would see those people, ( their clocks, their time) moving more quickly. But, flipping it around, from the perspective of the people further away from the black hole looking at their own time, all local time seems perfectly normal to them, i.e. all of their own clocks and time passage would be normal. However, those same people looking back at the person near the black hole WOULD see that person's time moving more slowly.
