How to Understand What Black Holes Look Like
ฝัง
- เผยแพร่เมื่อ 8 เม.ย. 2019
- We have just seen the first image of a black hole, the supermassive black hole in the galaxy M87 with a mass 6.5 billion times that of our sun. But what is that image really showing us?
This is an awesome paper on the topic by J.P. Luminet:
Image of a spherical black hole with thin accretion disk
Astronomy and Astrophysics, vol. 75, no. 1-2, May 1979, p. 228-235
ve42.co/luminet
Using my every day intuition I wondered: will we see the "shadow" of the black hole even if we're looking edge on at the accretion disk? The answer is yes because the black hole warps space-time, so even if we wouldn't normally be able to see the back of the accretion disk, we can in this case because its light is bent up and over the black hole. Similarly we can see light from the bottom of the back of the accretion disk because it's bent under the bottom of the black hole. Plus there are additional images from light that does a half turn around the black hole leading to the inner rings.
What about the black hole "shadow" itself? Well initially I thought it can't be an image of the event horizon because it's so much bigger (2.6 times bigger). But if you trace back the rays, you find that for every point in the shadow, there is a corresponding ray that traces back to the event horizon. So in fact from our one observing location, we see all sides of the event horizon simultaneously! In fact infinitely many of these images, accounting for the virtually infinite number of times a photon can orbit the black hole before falling in. The edge of the shadow is due to the photon sphere - the radius at which light goes around in closed orbits. If a light ray coming in at an oblique angle just skims the photon sphere and then travels on to our telescopes, that is the closest 'impact parameter' possible, and it occurs at sqrt(27)/2*r_s

Walter Lewin, legendary physics lecturer, just cited this video of yours as the best explanation of the image, in case you didn't know.
Just came from his playlist
Just came from his video
Be proud man. Good work
Wow!
@Joe Chang Lol yeah bro im sure an armchair scientist on TH-cam knows more about the way physics work then, you know, ACTUAL physicists.
It's funny, the black hole image they got is exactly the same as you drew on your black board. Why did they spend so much when they could just ask you to draw it?! Good job!
Based on theory, drawing a thing is called prediction. And when the actual image matches the prediction, that means that the theory is right. And till date, General Relativity Theory is nailing every prediction it made over a hundred years ago.
Rony Ronouk he knows, itsa joke.

FINALLY! This is seriously the first video that thoroughly explains the physics that I'm seeing. It's astonishing how simple this is to explain but yet NO ONE has done this yet, but you! Thank you! 😊
3 years ago. Who's to say someone didn't do this yet you just didn't happen to find it?
I thought the exact same thing!
@@TunaIRL Think about it…is your comment really necessary?
@@jj53368 Probably depends on what makes a comment "necessary". And then you'd have make a premise from it. Is it good or bad if a comment even is necessary?
I invite you to think about what you just said by asking, is your comment necessary?
But it's still a guess, since we don't fully understand what a black hole is.
The fact that the prediction was so close just goes to show how accurate theoritical physics is, we might not have seen the universe, but the physics we know helps us predict everything with a crazy amount of certainty.
Quantum Mechanics left the group
@@MauriceMuhumuza Not exactly. We've learned to predict the effects of quantum physics with a high level of accuracy, but the problem is, unlike relativity where something either "is or isn't", quantum physics is based on probability. There is no certainty of a single possibility like relativity, but we can calculate the probabilities, and have certainty that it'll be *one* of those probabilities.
@@ossiehalvorson7702 yeah, it's the nature itself of quantum physics. What matters is that we're certain about what kind of possibilities there are.
Maybe when we'll achieve a theory of everything we'll be able to predict quantum physics as well.
@@rayan-xg5kw The biggest obstacle at the moment is that, while we're getting very good at using and abiding by the "rules" of quantum physics, we're still pretty massively stumped on the fundamental source of those "rules", such as how and why those probabilities are set one way rather than another.
If we can figure out those fundamentals, I bet we'll be pretty close to a unified theory!
But never certain enough.
Watching this 9 months later to realize how incredible CLOSE his chalkboard drawing was. About 99% accurate to the real picture!
it just wasnt even more accurate because its impossible to recreate a 100% accurate image in a chalkboard lmao
Mojo Jojo lol
Same for me! 7:13 OMG he predicted the picture in the right way!
@Mojo Jojo I hope you are trolling
more like 100%
Wow, that was an awesome presentation on black holes. You made a beautiful, well layered physical model of the various aspects of the black holes. I'm going to be coming back to this. Quite helpful. The black holes point of singularity, event horizon, accretion disk, etc. are all fascinating to try and comprehend. ThankYou for sharing.
This single video just answered so many questions for me. I appreciate you taking the time to break all this down sir 🙏🏾🙏🏾

Fun fact: When they were making that movie, Interstellar, they tried to simulate mathematically accurately what the black hole would look like from far away more or less just as an experiment, expecting it to look so boring that they would have to embellish it in order to make it more interesting for the movie, but when they saw the end result it was so spectacular-looking that they decided to go with the mathematically accurate visuals.
Gargantua was absolutely stunning
Gargantua Black Hole is revolutionary.
Wish people would stop saying "fun fact" just get on with it
Yeah and then they actually contributed to the field of science by publishing 2 accurate papres!!! For those of u who wanna know a bit more abt this story heres the link to the vid from where i knew abt it: th-cam.com/video/D7Cv7x6jjYQ/w-d-xo.html Great channel btw for all of those movie fans out there!! (ps: love interstellar my 3rd favourite movie! :) )
well, not entirely correct. they left out the part depitcted in 08:28 as it was considered to be too complicated/confusing for the audience. hence, gargantua's accretion disk was portrayed as equally bright which would actually not be the case.
The best explanation of Black Hole imagery I've ever heard.
Yup
And for that reason alone
You should SUBSCRIBE TO MY CHANNEL 😃😐🚪🚶♂️
Super explanation. Just blew my mind. Now that it's almost 3 years after the first image of the black hole was shared to the world, I can imagine how much effort you must have taken to explain it in this way, before the photo was share in media. Thanks, and great explanation man. All the best.
I’ve been wondering about this for years, thank you for explaining it so well! Excellent video.
I finally understand that image of the Interstellar black hole. Thank you.
What image? It hasn't been released yet.
@@HelpMeFindTheseSongs the movie intersteller
@@HelpMeFindTheseSongs He means the black hole in the MOVIE "Interstellar".
PS: You posted a silly comment "1 minute ago" and it already has a like? Did you upvote your own comment? D:
@G123
Assuming you aren't a deliberate troll: In the movie "Interstellar," the only "explanation" for the way something looks in space was referring to why a wormhole would look spherical rather than like a flat disk (this is an entirely different phenomenon than the black hole Gargantua, encountered at the other end of the wormhole in that movie)
@G123 Haha, you call someone a bozo but you completely misunderstood the entire point of this video
MIND= BLOWN
Glad I watched this video before the release of the image. Hype increased by 90 per cent.
yes!
Same
Looks like this comment section itself is becoming a black hole, the words are getting sucked into TH-cam's even horizon, then spat out into the vacuum of space in the form of radiation. tsk-tsk
r/boneappletea
Percent* not "per cent," lol.
Thanks, this is the FIRST TIME that I have actually understood the 3D images I have seen of black holes. Previously I couldn’t get my head around what I was seeing, but not any more. Again, thank you for you simple, but detailed explanation. 👍👍👍
вернее сказать теория!!!
а не факт!
It makes me so sad that Steven Hawking died a year before the image was released… He studied the universe, and more specifically, black holes, his entire life… RIP Steven!
True brother..
*Stephen not steven
Well, to be fair, Einstein died far before he can see black holes. He's the one introduces the general relativity theory; he was also speculating on black holes; Stephen also contributes to this knowledge too. And yes, they have tremendous contributions. But our future generations, should also contribute and may not expect to see them. Because science is all about contribution to the community for future generation to see and use. 😊
Stephen Hawking was an evil, vile man
I think we can find solace in the fact that he used mathematics to see it for himself long before the image ever came to be.
Black holes: "Neat."
The prop work in this video: "OH MY GOD, THAT'S AMAZING!"
I know right?! It is something that is easily overlooked.
@Dave Micolichek that doesn't make sense.

Just like The Curiosity Show
I guess you have no ideea how hard it is to make CGI.
Correct, sometimes (or many times) CGI caused too much impression that distracted viewers.
This is the first time I've seen an explanation for not only the telescope images you referred to in this video, but why the Interstellar black hole was shown the way it was. I'm glad to know that the images from the movie were informed by science and now I've seen this explanation, I understand! Thank you!
Dude, what an absolute fantastic explanation with a practical and very understandable demo. bravo!

By far the best and simplest explanation on why we see black holes the way we see them.
Thank you very much for explaining this. I had looked at the black hole representations and never understood what I was looking at until I saw your detailed explanation. Thank you!
Mind blowing. Both, the black hole stuff, and your capacity to explain very complex things in a way everybody (even me, ha ha) can truly understand.

Exactly. Impressive explanation for the masses ! Can t wait for tomorrow now
Wow, you're very smart, goodluck man wowww so smaartt
You absolutely nailed the "fuzzy coffee mug stain" description.
Well if he had drawn anything else it would not have made sense with respect to what a black hole is supposed to be and how it interacts with light and matter (And spacetime). He did explain why it would look that way. If it had looked much different then that would have been exciting for a whole other set of reasons. That's what I love about an observation like this...no matter what we saw, it would have been a huge confirmation(s) or a huge discovery. It's a win-win.
Low Key Sound System jajaja
Captain Obvious you think youre cool cuz you can laugh in spanish? Stfu
No surprise, really. Scientists have been looking forward to something like this for DECADES, that description must have been circulating since the concept of taking a picture of a black hole existed.

By far the best explanation of a BH I ever saw. Thank you for teaching me something new. BH are amazing entities.

Thank you a lot. This video is absolutely the most understandable. You have found the most effective way how to explain all that phenomena of the black hole. Thank you once more.
Fun Fact: The Schwarzschild radius is named after a guy called Schwarzschild, whose name translates to black shield, which makes a lot of sense.

We all new it'd be something like that. In fact, Derek's prediction is hi-res which is not possible yet in reality as M-87's centre is 55 Mn LY away!

This is the best explanation I've ever heard.
I couldn't understand any of the black hole pictures I'd ever seen.
Even when I searched through science textbooks during my school days,
when science teachers explained this to me,
and even when I watched TH-cam as an adult,
I couldn't find such explanations.
There is no such a thing like a black hole. This film is outdated..
That moment when Derek predicts the black hole's image spot on.
HARD PP I know we have the coolest science teacher and he's on TH-cam!
Hat off to you!
He didn't predict it since researchers have known what its supposed to look like for a long time. They just never had any actual proof. He just explained it really well.
I mean he showed a picture from the movie Interstellar that showed what a black hole looked like, and that movie was released 2014.
Pun not intended

Is 'hype' cool now, like when 'bad' started meaning 'good'? If so, what word do we use to describe disproportionate ramping of people's expectations?

This is.... SPARTA!!!
@@canalsocialismocristao4605 You seem to misunderstand the concept of electromagnetic waves. We are only able to see Photons / light waves from 400 to 800 nm wavelenght. Anything below or above is still light but we can not see it with our eyes. So even if the image is from a radio telescope it is still light and it's photons that are captured in the image. The only difference between light we can see and light we can not see (such as Infra-Red or UV light) is the frequency and therefore the wavelenght of the emitted photons.

No joke though, spot on.
this is why theoretic physics is not "just theories". Note: "theory" in science is something different than "theory" in casual speech.
Just wrong about which black hole they 'took a picture' of, though! (But the explanation is fantastic).
Hi,
Thank you for the explanation & the animation. I was intrigued by the representation of black hole in my all time favourite Interstellar but did not understand it fully. Thanks for answering the same. 👍
This is fabulous. I've pondered and pondered over the "shadow" and why a black hole was always represented with an extra halo disc of light. I'd use the old whirling down a drain analogy but there is no extra disc when we watch water tumble down the drain. This makes sense. First it helps to understand the Schwarzchild Radius. Not knowing it existed how could I actually understand the reasons for the images offered. I could never figure this out by reading the published literature. I'm not capable. But your explanation helped me to understand something I've been trying to figure out ever since we've had our first representations of a Black Hole. Hard to believe that light could swing around the Black Hole and not get sucked in...Schwarzchild Radius helps us understand how that is possible. Understanding the photon orbits is key. Thank you. Oh and how can one not think about Gravitational Lensing when talking about the reflections of accretion discs, eh? Not the same thing but Gravity definitely doint its thing!
I can only imagine the joy and satisfaction these scientists get when all of their theories and calculations were confirmed. It's crazy just how much we can learn and understand about our universe with just a bit of observations and equations. Newton had to create an entirely new kind of math just to be able to explain his theories, at the age of freakin' 23!
Said every scientist since the dawn of time

Scientists actually like being wrong. Because being wrong is the opportunity to learn new things, maybe even deep truths about the universe.

Hats off to the astrophysicists who study this stuff. As an engineer, this is mind-boggling!
@pyropulse Both physicists and engineers were required to accomplish this
Hats off to all beings as we make everything possible with our conciousness. Have a good day.
@@BenExcell Hats off to hats...
Hats off for people with hats on
True🐺
*My recommendations*
Are now bombarded with Black Hole videos
TH-cam is not for porn, pervert algorithm!
Beornen Mannr WTF SAME
Black hole > black people
Duchi so are mine!
Which means you use TH-cam correctly 😉
Awesome explanation. Too easy to understand. This was always one of the things that I was curious about.........what exactly am I looking at? and you answered that perfectly.
simple explanation to a complicated phenomenon, really enjoyed the vid
Derek I remember several years ago having to upgrade my internet account for the sole purpose of watching your awesome HD videos. To this day, you continue to output amazing content.
Best TH-camr ever.
That’s quite high praise. I’ll leave a comment to get yours higher in the ranking.
So wholesome.
it's MUCH more accessible at 56.6k

@@JM-us3fr so will i
"...if you have any questions..." - no sir, it all makes sense
Are you sure you REALLY understood it?
Pretty much everyone after watching Interstellar lol
@@peterobinson3678 Yeah. I mean, it was pretty simple wasnt it? To paraphrase: Speedy thing goes in, speedy thing goes out. Except when it doesn't. Because not even speedy thing (light) can come out a black hole.
Or in laymans terms: Space bends, parallel lines intersect.
@@feha92 I can hear Sam O'nella saying in this exact same way to explain this entire 10 min long vídeo!
LOL
Wow, that was a fascinating explanation. Many thanks!
I knew light is bent around a black hole but I never really grasped the extent of the phenomenon until now. It would probably be very confusing to look at a black whole up close.
Thank you very much for explaining why it looks like it is going up and down and sideways at once. This has been giving me a massive headache trying to figure out why something I perceive as flat looks the way it does.
100% spot on .
Predicted image matches exactly with the real one....
real one is also a bunch of images, they put it together with prediction
@@viveksawant8401 no
man 10 it’s actually true, they had to have multiple telescopes around the world in order to capture the photo
@@LuisDiaz-go3wl agree. but he used the word prediction and that is not a right word.
man 10 ahhhh I see I see, sorry for that fam
its amazing to see how science theory predicts on the yet discovered things in our universe and yet some people still think the world is flat
Flat earther: "I didn't understand a thing of what you said and anyway I don't care. Here is why Earth is flat instead..."
Those are Tesla Fanboys who hate theorists
@ Who the absolute hell is talking about Trump? Why are you so obsessed with him?
@@cubiusblockus3973 wow, i didn't know it's officially classified as a syndrome
And denying evolution and vaccines
Dude was spot-on with how the real black hole would look. Very clear, informative video.
EXCELLENT! Answered so many of my questions! 😁 THANK YOU!
