If only they were actual holes instead of massive cores of even more massive stars which have so much gravity that light cannot escape its surface. There aren't stars that massive in this universe any longer which has a core as massive as out black hole..

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.
Drinkyoghurt

Time being relative, would it even feel like 20 years on one of those stars or would it be significantly slowed down? Would experiencing being sucked into a black hole feel like an eternity because of the sheer speed you'll be going at?

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.

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’.

@Rockyzach88 The image is not the data converted into a picture at all. If they did that you would be presented with 3x2 enlarged pixels that would not show any sort of form and would not be very impressive at all to the public. So what they do is they create higher resolution images that are guesses at what they *might* see if they were able to obtain a higher resolution image. Guesses that when reduced in resolution, match the very low resolution data that they do have. The thing is that that there are countless variations of a higher resolution image that would fit with the low resolution data. They pick one, to show the public, which most closely matches their theory. That image is not proof of anything but people here have clearly been given the impression that it is.

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.

​@popuscornus42 Proven false. If General Relativity was a correct description of gravity, those stars that closely orbit Sagittarius A* would display clear signs of gravitational lensing when they pass behind it. They don't because the theory 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 examples of conventional lensing due to the density gradient of a gas cloud or an atmosphere.

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?

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

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?

Absolutely not necessary. There are thousands of videos on RU-vid explaining exactly what a black hole is in excruciating detail. we do not have time as a species for every single science video on every single subject to start at the very beginning because some people won't go and look up what they don't know, and want to have everything spoon-fed to them. You clicked on a video specifically talking about a picture, and the title made that clear. if you want to know how a black hole is formed, or what all of the parts are called, go click on a video about that. Don't expect everybody in the world to spoon feed you every ounce of information you have in your head.

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.

@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.

Yeah man if you pay a good computer graphics guy to make anything out of basically nothing. I took a picture of my racing streaks from my underwear, they were just some brown lines on white underwear. 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?

15:37 This animation explained all. I loved how he explained the image of black hole and we seeing a whole sphere around black hole in the circular image we see was mind blowing learning 😊 Keep up the good work Veritasium❤💕

I love watching these videos and the theory is exciting and logical assuming a black hole really exists. It just makes good sense to us.

I can imagine that if someone were to be a few lightyears away from a black hole, they should find common instances of atoms and bigger chunks speeding through space at nearly the speed of light. I'm glad that our universe has ambient space dust scattered around everywhere.

This is the clearest explanation video about black hole i have ever seen. Now the rest of the black hole videos can make more sense. I would like to see more detailed video about each part/layer of black hole talked about in this video.

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.

Actually, it is NOT einstein's theory of general relativity. It was plagiarized from Hendrik Lorentz and credited to that overly-glorified patent clerk.

the 2019 image was only 2 pixels; it literally confirmed nothing, as advanced mathematics they used can literally produce any image you want. The just threw out all the image processing that didn't look like a 'black hole.'

I could listen to you explaining the image of a black hole everytime :') loved the explanation of how the network of telescopes are able to combine their images and produce the images of the black holes too thank you

Super interesting video thank you a lot! Interference is really our best buddy for the detection of the smallest deviations of... well anything. Can you elaborate how mass ever falls into a black hole? From the view of an outside observer time at the event horizon should be stretched to infinity. So how would a black hole ever grow?

Really very interesting , i always look at new Veritassium videos , sure to learn something out of ordinary , nobody can explain complicated things so clearly. Thank You. Question could we have in the future a radio-telescope on Mars doing spectacular interferometry ?

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.

Hi, fellow stupid, unintelligent human and neighbor of yours here… just wanted to thank you for going into that field and helping advance science and our understanding of the cosmos. If I could go back and redo my life I would have chosen the same career path. I chose to mess around in school, do drugs, go to concerts, ect. Although I don’t regret my choices and I had a BLAST none of it helped humanity or the advancement of our species. It’s bigger folks like you that do that so I thank you, and Derek. ❤️

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?

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.

Hello Veritiasium, i tried to search for any of your videos explaining how does activated charcoal absorbs/removes odor. I tried researching and most of them claim that they can remove odor, but i am interested to understand the mechanism of action. thanks

Great explanation and awesome visualizations! But still 🤯 I'm in awe by all the clever people figuring these things out. These images also remind me of the images on a speeding ticket. Quite expensive for an image with such a bad resolution ;-)

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.
