My younger self can confirm that a blurry image of something really exciting is pretty exciting itself.
I loved blurry images from Japan when I was younger
For me, it was channel 81... nothing like waiting 30 minutes for a slip in the static lol
Blurry image must be black hole because it's blurry an from "nasa"
😂😂😂 we've all been there haven't we
@@MisfitRecords But this isn't from NASA..
5 petabytes (5.000 terabytes or 5.000.000 gigabytes) of data for an image of 864 kilobytes.
Amazing!
The compression ratio is impressive ;-)
I’m thinking the process was mainly about picking the relevant information out of all the noise, and there was an awful lot of noise!
And they could not transfer 5 Petabytes over the Internet!?
@@sebi7794 Because that would be 57.87 days of uploading with 1Gbps.
On a normal-ish 50Mpbs, you'd be looking at a full 3.17 YEARS of uploading.

@@DutchmanDavid Yes, of course. But when I see which connection speeds the universities here in Germany regularly use to exchange data, were are talking of 10 Gbps or even 100 Gbps. It would not have taken long to transfer the data.

Amen.
What about the ping?
I read somewhere that one of this hard drive deliveries constituted the fasted data transmission speed ever achieved.

"Never underestimate the bandwith of a truck full of magnetic tapes" - A. Tanenbaum. (He was right even all this years later).
I've been interested in black holes since I was a kid, my grandpa told me it was just a theory and didn't exist. Look at where we are today
Was your Grandpa, Einstein??
Nah just a civil engineer lol we used to joke about how young adults couldn't pass calc even back then.
Well, they still don't exist - and even if they did, those pixelated preciosities right thar ain't really proof of that claim...
Well, theories are based on experiments and observations, so I guess he mean an hypotheses.
Today black holes are real, and your grandpa doesn't exist. Look how the tables have turned.
Thanks Brady for getting this out so quickly!
Hey that’s my name!
I remember reading an article about seismic data, where the scientist said something to the effect of "Nothing beats the bandwidth of a UPS truck full of harddrives."
Yup! A. Tanenbaum
And to think of it, this is how it used to look several millions of years ago !
55 million, in fact! That's quite a lot of millions!
yash96819 haha! Right you are
When the electromagnetic waves left the black hole, the species that would one day observe them didn't even exist yet.
Best comment in this whole comment section! 👍
Do we actually have a guess as to what the current state of that particular black hole is? As in, if we instantly teleport there (like goku) what would we see?
It's an absolute privilege to live in an era where all of these history-making breakthroughs keep coming one after another at an accelerating pace. What an exciting time to be alive. :-)
Can you imagine the things we will see in the next 50 years? Technology is advancing so fast. I think we are going to see some pretty amazing things in the next 50 years. Exciting times in deed.
I know, I was thinking the same thing! In my lifetime, humans have: invented the internet and smartphones, discovered the Higgs boson, discovered gravitational waves, taken the first picture of a black hole, created the first synthetic organisms (including one with a genome designed and produced almost entirely with AI!)... and I'm only 28! These are truly exciting times, indeed :D
@@IceMetalPunk I'm 34. I agree. Just in our short lives so many advancements have happened
21 year old here. I can’t wait.
And yet, essentially we still use the same hierarchichal, socio-political and economic model as an ape. Most systems in use today are even predatory in nature.
Although we have found ways to delude ourselves that we are 'civilised' (e.g. the clever use of complex terminology to describe (or veil) our animalistic tendencies), the truth is that while our technology and science has progressed, our mindset has not. Our mental scope and awareness is woefully inadequate to handle the responsibility of even some of our earlier scientific discoveries.
As long as this issue is not being addressed, all the science and technology we have will be used to advance the agenda of the animal. And humanity will not benefit from it. Quite the opposite.
I remember looking at THAT Pluto picture in complete awe some 15 years ago, just a couple pixels really. I'm no expert by any means, but now that I'm older and have matured in terms of scientific understanding, this picture still absolutely blows me away. It's just so beautiful, I teared up during the release. Great work to all the researches involved in this feat!
I wish Hawking was around to see it!! This is incredible!!
@1 2 Ever heard of Hawking radiation?
@1 2 True but I think OP mentioned Hawking because he only recently died. He almost got to experience the sight of something he spent a lot of time researching.
@@frogdeity which has not been proven to exist as far as I know.
@1 2 who says they have? Maybe we are the ones missing out.
They took this picture 2 years ago and have been analyzing the data I'm sure he knew about it and possibly even saw an early version
Professor became a lot older since I've stared watching this channel :(
Doesn't make him any less awesome. I think he looks great for his age.
Yes. We ALL age. Why be sad about this?
Entropy catches us all eventually. No shame in it.
He wouldn't have aged a lot if he had been living near a black hole ;)
@@tatjanagobold2810 He would have aged the same on his watch, but almost nothing on an outsiders watch
I am doing my PhD thesis in compressed sensing. Seeing the concept applied on such a large scale and with such an interesting object feels really amazing.
Now all we need to do is use gravitational lensing to increase our zoom power to perv levels.
Share publications
Now take some undergraduate courses which cover such topics as signal to noise ratios and information theory, and you'll soon realize that this is nothing more than a complete crock.
The fraud is readily apparent, as there is a COMPLETE ABSENCE of any radiating matter except on the circumference of the image, and none in the center whereas, according to theory, a black hole should be surrounded by a completely enveloping cloud of matter outside of the event horizon (and therefore visible), which is also radiating energy as it spirals into the black hole.
This isn't science, it's a poorly conceived forgery being used to justify the tremendous amounts of money they wasted on this poorly thought-out boondoggle.
Seriously, if you are throwing out 99.9999% of your data, that means you're just cherry-picking the 0.0001% of data which you decided to keep because it fits your pre-conceived notion of what the data "should" look like.
Unfortunately for them, they forgot to include eclipsing matter, which thereby proves that the image is a complete and utter hoax.
Is your thesis going to cover the fact that when you eliminate 99.99999999% of the data through the "sifting process" you can pretty much force whatever result you want?
Aliens: **checks off "Found black hole" off requirements to be an advanced civilization checklist**
I'd grade that a Sagittarius A*
*laughs in black hole farming*
@@dropit7694 *cries when your black hole farm goes haywire and end up in a kilonova*
Why would an advanced alien race have such a checklist? Surely they would be just like us, in that any discovery of life outside their own home world would be followed by attempts to learn about it, and if found intelligent, to communicate. I suspect this idea that advanced aliens won’t communicate with any other intelligent species unless they meet some arbitrary standard of advancement is just a poor explanation for why we have never been contacted. And I suspect the real reason is because there are no aliens.

I've been fascinated by black holes since I was young, much like my obsessions with documenting weather. I never thought I would see the day I'd see anything like that photo. We've been relying strictly on simulations and artist rendition since...ever. Doesn't matter how blurry it is, the fact that it is actual light being distorted by an actual black hole is truly awesome.
You've been fooled. This picture is yet just another artists rendition.
The raw data comes from 1.5mm radiowaves ONLY meaning it's pure fiction, because humans can't see radiowaves.
You got bamboozled once again.
See also Veritasium’s explanation of what we expected to see based on the physics before the image was published
Yeah his video was great. Gave me a deeper understanding of how light and matter actually circle around a BH
This reminds me a lot of the early images of Pluto- I can't wait to see what surprises are revealed in the upcoming years!
haaa
This reminds me a lot of the early comments you made.....
Planet 9 is the one I'm most excited about, assuming we confirm it.
@@mentalrectangle I'm an old git, so Pluto is 'Planet nine'. :-)

Another wonderful video from Dr. Brady Haran!
i always get giddy when stuff like this is announced like when we got those close up on Pluto from the new horizon
It's so nice to find this Channel. This is by far the best highest quality content I've ever seen on youtube. Thank you so much
U are just little late
I remember when this collaboration was mentioned in How the Universe Works in Discovery Channel and amazed how they worked together, telescopes, to sort of create one big telescope.
Yep for the second black hole images look up "First images of black holes!" ( veritasium channel )
Science 2nd one is a simulation
So in other words we got a picture of something we can't actually see that was constructed from a simulation based on a theory of how a theoretical construct that a black hole is which is based on a contradictory math would look like?
While we are at it have we found unicorns yet?
Brady, of all the science channels I'm subscribed to, your video on this came out first.
You win youtube, I guess. Congratulations.
Really great video. Thanks for the breakdown.
Im excited for what this means for the future of astronomy. Especially for sharper and clearer images of black holes. The potential for verifying Hawking Radiation. Maybe observing smaller stellar mass black holes once we get the techniques and the technology figured out.
Blurry images really excites us since we were young
The thing that keeps puzzling me about all of the explanations is the brightness asymmetry. Shouldn't one side of the black hole be BLUEshifted and the other REDshifted rather than brighter vs. dimmer? Is the color shift just represented by brightness in the picture because we can't see the colors in radio waves? or is it an actual shift in brightness itself? brightness is just how many photons you're capturing, right? so there shouldn't actually be a difference in the number of photons received from each side of the black hole, right?
He didn't say they were brighter, he said they had more energy. Blue light has more energy than red light when it hits the detector. This image does not convey anything about received frequency.
It seems its less a matter of "analyzing" the data, than "embellishing upon" the lack of data. If we cannot resolve an object a few light years away, how could we begin to resolve an object 50 million light years away?
People from Andromeda or other galaxies may be watching our Sagittarius Black hole of the milky way aswell.

Yeah don't dehumanize the aliens
The thing that gets me the most about this photo is that it looks precisely as we've always thought they'd look, and in every movie (like interstellar), they've based their ideas exactly on the right idea. Which was Einstein's, and that's extraordinary, and think I finally understand what people mean when they say that "Physics is NOT math!" Let me explain.
The mathematical universe produces all kinds of crazy structures like infinities, klein bottles, infinite dimensions, the whole nine yards. It produces many, many types of objects that just don't occur in nature. Physical reality doesn't seem to have any of that, it's very narrow in that way where it can be described mathematically but is not, in essence, pure maths. And therein lies the remarkable bit, because with this implies that there's many. many ways to produce a math equation which does not describe anything physical, and there's also lots of ways to produce a physics equation which makes SOME accurate physics predictions, but also produces non-physical mathematical structures. This is the great issue with String Theory where physicists aren't sure whether its predictions are purely mathematical or if it's physics, or maybe it's partly a bit of both. How much physics does String Theory really describe?
Many physics equations like this example exist and which have that purely mathematical bit. It's now easy to see that they are inadequate physics equations. That is, they aren't exactly true.
Einstein, though. Einstein produced a theory in General Relativity which seems to describe ONLY physical phenomena, no matter how outlandish the claim. GR says that time stops and slows depending on mass and speed, he predicted that space is curved like a dimpled bed spread, GR says gravitational waves should be produced by the merger of two black holes and that black holes should exist in the first place. NONE of these predictions were guaranteed to match with REALITY, Einstein thought that surely he had erred in some shape or form and produced an equation part math, part physics where you get mathematical anomalies cropping up here and there. But now we see, General Relativity is the most perfect PHYSICS equation ever produced, because every time, no matter the challenge, it always makes accurate PHYSICS predictions, and I'm not exactly sure how he was able to do that.
if i was religious, id have an answer for you, but since im not, i dont know either ;)
Physics is not ALL POSSIBLE math ... just a slice of math that allows our consciousness to exist.
We -- the observers -- don't collapse probabilities into certainties. Rather, only the certainties that allow observers get observed.
Based on your phrasing, you make it sound like physics is a _subset_ of mathematics---the applicable bits.
Also, Einstein's equations are potentially erroneous on large scales, which is where the ideas of dark matter and dark energy are needed to make sense of things.
It wasn't Einstein's, it was Swarzschild's interpretation of Einstein's equations that "created" black holes.
And of course the result ended up being exactly as predicted. That's because the theory behind black holes and the equations used to construct this pictures ARE THE SAME EXACT THING.
It's called circular reasoning and it's impossible to get any other result with this methodology.
Oh, and for how many times you mentioned Einstein's name... let me inform you that Einstein did NOT agree with Swarzschild and outright stated black holes cannot physically exist.
PS. Theory of relativity is falsifiable. GPS is the best proof that both General Relativity and Special Relativity are wrong.
The black hole itself looks like a planet that is in the line with the star and covering it ,but also at the same time not . i waited for so long and its so amazing to see something for the first time that scientists predicted and made theories about come true .
Got to appreciate the sheer amount of sciencie, effort, hard work, engineering and technology it takes to push the boundaries just a little bit
"Well, there it is." - Jeff Goldblum
"Must go faster"
Unfortunately, the claimed resolution is over 1,000 times the incoming signal resolution so basically the picture is a photoshop special.
Kind of like your claimed education.
Congratulations to astronomy on such an incredible accomplishment!! I cried when I saw this beauty for the first time myself and I’m not even a physicist!!
The image was actually put together by a graduate student from MIT, Katie Bouman.
If we had placed space radio telescopes in Langrarian points L4 & L5, would we be able to get better resolution?
Well yea kinda... it would make earth's orbital radius into a huge virtual telescope
In theory it's possible to build a telescope array in orbit which would act as a really massive telescope, so yes. In practice it's not easy.
Just one of the problems is the data. Here on Earth it was already too much for the internet and it was more effective to fly it in hard drives. Just transmitting it from telescopes in orbit would a big challenge.
David Wych They mean to add any space telescopes to increase the size of the virtual telescope. Yes that would work.
OOOOOO Look how smart I am
@@esuelle Okay, what if we had more than one manned space station/observatory, with the HDDs periodically taken down to Earth to be combined and analysed; would that work?
I'm not a physicist and there's something I don't understand. We see a black hole surrounded by a halo of radiation. But surely a black hole is a three-dimensional object and the radiation it emits would be bent round it, forming a roughly spherical envelope. If this is so, wouldn't the radiation envelope between us and the black hole obscure the black hole itself? So why do we see it so clearly? Can some kind person help me out?
I've wondered that too. Unless, it's not radiation from the accretion disk, but something behind the black hole that's bending the radiation in our direction. And if it is from the accretion disk, then it's circling the black hole in a 2-D plane, but not enveloping it all the way around. We may be viewing the top or bottom of the black hole, and hence we're able to see the radiation from the accretion disk like viewing the rings of Saturn from the north or south pole.
Of course, I could be completely wrong on both counts.
@@jeffo9396 Thank you! Clear explanation!
Thanks for including me 😊
Thank you Brady!
Phenomenal job, Brady. Thank you and everyone at Nottingham.
This feels like a 'Man on the Moon' moment. Great vid. Thankyou.
Big step for all the past and present men and women who work so dedicated in this field of theory. Great accomplishment for the imaging teams you made it the size of the planet.
Any "black hole photograph" in question is a plasmoid, matching the description and sketches/photos of Winston H. Bostick in the 1950's. These plasmoids are extremely dense with energy and have the same properties as a "black hole", only they actually do exist and at all scales. In addition, as a top authority with impeccable standards of moral integrity, Dr. Pierre-Marie Robitaille is unmatched in his refusal to bend the laws of physics. You owe it to yourself and your audience and followers to watch this video on RUclips: "April 10th, 2019 - Claims of a Black Hole Image: The Day Astrophysics Died", AND his followup videos with all the details to bury this farce forever.

Its pretty well explained without discrediting the work out of the probably thousands of generated results you take the one witch fits best to your predictions. Thats why its always so funny to see the amazement and reactions when a sattelite finally reaches a far away body and takes close up pictures or gets damaged by unexpected particle fields. And theories are forgotten and rewritten without any hesitation.
That's how science works. Theories change to match new data. That's how we learn.
Profound. Beautiful. I'm so glad I've lived long enough to see this.

Great job getting this together so quick! Wish I could take a class with each of the professors.

I was waiting for this video. Thanks for delivering Brady.!
Brady, sir, please keep us up to date with the subsequent findings and analytics!
this is insane. the magnification is like if you zoom in on a coin on the surface of the moon. the calibration of the different telescopes alone required the exchange of petabytes of data. the image we see is 55 million years old. and einstein just keeps being right...amazing
Such absolute nonsense. Are we really expected to suspend our judgement and go along with this? 50 million light years distant. I object to my tax money supporting this fraud..
@@WSCLATER lol ur a idiot. time dilation?
Star Trek huh
@@WSCLATER Sure it is mind boggeling. 50 lightyears is not a distance you or me can easily comprehend, but we can actually check those distances via redshift & stuff.
It's amazing to me how well we can predict such images... I mean yea, the image is blurry but given the distance it's amazing.
Btw: such experiments are used to verify our understanding of our world which in turn leads to further technical advances... so it's benefitting you for more than just a nice image ^^
Science fiction, has become accepted science.....

What is amazing is the total lack of scepticism among the captive laymen.
pretorious700 it’s very frightening, imo
So have you read the paper or are you just using scepticism in a newly defined way?
The naivety of science denying morons who fall for crackpot theories and think they are being sceptical is astonishing.
@@johnstaf Indeed. People think scepticism is only about not believing things when asserted instead of actually doing their due diligents and learning what the actual claims are and what is the evidence brought forward.
@@johnstaf OK, so let's recap:
1. A purely mathematical theory predicted an object like a black hole (not Theory of Relativity per se, but Schwarzschild's interpretation of it)
2. To photograph this object mathemagicians had to jury-rig an Earth-sized telescope from a bunch of scattered telescopes on Earth.
3. Anything smaller wouldn't even allow them to get any usable data, making the "raw" picture something like a 8x8 pixel blob.
4. The only wavelength that was obtainable was a narrow band of in the radiowave spectrum, meaning even if translated into visible spectrum, it's nothing more, but an artistic interpretation to begin with.
5. After several years of applying the same theory that predicted the object to that data, the computer was able to construct an image that's at least 45 times bigger than the raw data.
6. This is considered an achievement for science.
This isn't the scientific method, it's circular reasoning.
I wonder if we can put telescopes on other planets in our solar system one day, and create a radio telescope the size of our solar system.
Just putting a bunch of them in space would be a better option.
Sir Awesomeness True. Maybe orbit around other planets then. You do want them in some predictable orbits/trajectories somewhere.
I think this is already in the planning stages. I have heard of this before, I forget where.
@@avonord It'd be better to just have them orbit the Sun directly. It's still predictable, but gives you less noise as it's just one orbit to deal with instead of two (around the Sun and then around the planet).
IceMetalPunk Hmmm. I’m no expert. But I’m guessing achieving stable solar orbit may not be possible with all these planets flying around.
This is the one I was waiting for
Just a question... Can this technique be used using the translation of the earth around the sun (summer, winter) to make a telescope even bigger?
if anyone watched the NSF release, some of the early journo Q's were like OMG, hilarity
Yesterday I almost cried on how wonderful it is for astronomy, but now that I saw some physicists' reaction my heart is full of hope and joy-
We're living an incredible day for astronomy and I'm glad I'm still here to witness this... This blurry, low resolution picture is a beautiful proof of something we thought we could never see
Science is so inspiring
Big congratulations to the scientists who worked all this time for this incredible yet true picture!!
One thing that's really valuable from this effort is the confirmation of certain black-hole models and theories. The models and theories that produce the same kinds of results we see in the image are the keepers; the ones that don't can be round-filed. Validation of theory is probably the most valuable aspect of this work- aside from finally proving the existence of black holes beyond any shadow of a doubt!
BHs are a far shot from proven "beyond any shadow of a doubt" - and as for "One thing that's really valuable from this effort is the confirmation of certain black-hole models and theories", don't be naïve; there's _one_ theory of gravity going around, and only _only_ possible model for the gravity potential outside those massive lumps - a pretty hard bet to make, huh?
I'm a little confused about where the ring of fire is in the plane. It looks like it's spinning around the black hole in a vertical circle but in order for the doppler effect to work, the light would have to be coming at us from the bottom and going away from the top. Is the ring in a vertical or horizontal circle?
Loved for the little six year old boy comparing the image to the plushie: what an awesome moment of context. What an amazing universe we live in.
Wow, there it is. Well, one of them. Sure glad its a long way away. Feeling kinda protective of our little planet.
Thank you to scientists who study and learn and share their knowledge. Research is so important. Its so awesome to see that pic. I wish Stephen Hawking could have seen it, but he already knew he was right.
Don't worry, there are probably thousands of black holes wandering around our own Milky Way. They're just close to impossible to spot unless one were to show up on your doorstep. :-)
Fortunately, they probably won't. Space is big.
Well you've talked about black holes, you've talked about cosmic strings/super strings, are you going to make a video about another type of singularity, the domain walls?
I'd love to learn about that! 👍🏻
Love the channel guys. Wow

Rainbow Dash - the only one who can escape the gravitational pull of a black hole.
hey! that's related to black holes okay?
Why is the bit coming towards us brighter if we're perpendicular to the plane of rotation?
This is heavy! Great Scott!
I remember when I was very little I mentioned black holes on a school paper and one kid told me they were science fiction
I feel slightly vindicated
Excellent interviews and amazing image of a galactic supermassive black hole. Even more amazing is the rate at which astrophysics is progressing.
What we really need to do is build a constellation of space-based radio telescopes that we can arrange to effectively make a diameter of approximately 1 million kilometers, maybe 30 or 40 of them and really get some great resolution.
Northern: How about "really want"? I don't see the need, at least until we solve a couple of intractable problems here on earth.
Well done. Proud of you guys
So the image is interpolated from what we already know and what we expect to see?
But how well do the measurements match R=2GM/c^2 ?
That would be the Schwartzschild radius, I would think it could be anywhere inside the inner edge of the disk but we could deduce it if we assume the inner edge of the disc is the edge of the photon sphere which is 3/2*Schwartzschild radius
The photo precisely matches predictions by multiple equations. See Veritasium's video on how the schwartzchild radius would actually appear in the image due to light bending. I actually took some of the simulations they showed and applied a gautian blur to them and reproduced very similar images. I can't wait to see how this image helps the field of Quantum gravity.
The hole is probably rotating, so it's not exactly Schwartzschildian.
@@mmn486 very true, that's an important point.
What time frame were the collated images taken over? Days, months?
Chuck Norris just came out, and said that the image of this one is similar to the one in his black-hole image collection.
Great to see the nearly peerless Sixty Symbols on this Event. So much more Gravity than many of the other science channels.
Does this resonate to first Pluto images to anyone else? and what we got from flyby later on...
What somewhat surprises me is that there is no talk (yet) of putting a radio telescope at Lagrangian points L4 and L5. And, if we did, we could use them to relay the data that a radio telescope at L3 receives.
4:06 The radius of the event horizon scales up by a factor of 2 with an increase in mass. Double the mass and it's radius is 4 times bigger :P
This is fascinating. The scientists who took these images should be very proud of themselves.
