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.

The better question is: does it blend? ok jokes aside, i think of questions like if the star void/black hole has momentum(moving, not rotating), is it more energy dense than matter around(in its orbit), is it more correlated against the motion of other black holes as to the expansion of the universe or destined to collide with another star void?... are much more valued questions to put on Youtube for now, not in a Ve video yet lol ;)

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).

Vor Tag

@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.

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.

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.

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.

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’.

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?

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.

Sir, I have a doubt. In super massive stars, do the helium atoms(resulted from hydrogen fusion) start fusion to form carbon only after all the hydrogen atoms are fused and used up (to form helium)?

Hello and thank you for the very good explanation of the image tech and science. Just at the end i got lost a bit and would like to ask why, instead of seeing just one brighter spot (as one can see in your simulated image due to the Doppler effect) can we see 3 brighter spots in the real image? Is it because we do see 3 diffent planes of the horizon? Any further explantion would be very much appreciated. Thank you and all the best for your next projects!

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?

I enjoyed watching this, but it feels like Derek missed a very important part of what we wanted to get out of this video: what do the different parts of the new black hole image mean? And what can we learn from this specific black hole? Although his previous video on black holes was great, it doesn't make sense to have have a new video that has a large part of an old video in it. All in all, this video felt a bit rushed, which is not what I expected from Veritasium.

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.

Wow, are people outside mainstream cosmology really that stupid? Almost as stupid as thinking the image shows an accretion disc with a black hole at the center, as if the image is taken in plan from directly above or below viewing along the spin axis of the galaxy, a neat trick for Earth or any galactic body-based telescopes. Or does it not occur to anyone else that if we were to observe the accretion disc of our own galaxy's black hole from here on Earth, we'd actually see it edge on?

@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.

I loved the revisit to your old explanation from the M87* image.

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.

What is the difference between quantum tunneling and wormhole? The particle borrows enough energy from quantum fluctuations to perform quantum tunneling within the time limit of the uncertainty principle, and returns the energy within the time limit. Energy bends space-time, and wormholes are channels formed by space-time bending. Do particles complete quantum tunneling by opening wormholes with energy borrowed from quantum fluctuations? Can quantum tunneling allow particles to tunnel from one planet to another?

I wonder why we always need to explain the singularity as a infinitely small point, I guess this comes from the math that breaks up but it would make much more sense that the actual core is not a single point but a very dense mass. The size of the black hole event horizon grows as the non-infinite mass grows larger. If the all the mass would be an infinite point who then we could see different sizes in black holes to start with...
