My younger self can confirm that a blurry image of something really exciting is pretty exciting itself.

5 petabytes (5.000 terabytes or 5.000.000 gigabytes) of data for an image of 864 kilobytes. Amazing!

"Never underestimate the bandwith of a truck full of magnetic tapes" - A. Tanenbaum. (He was right even all this years later).

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."

Thanks Brady for getting this out so quickly!

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

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!

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. :-)

And to think of it, this is how it used to look several millions of years ago !

I wish Hawking was around to see it!! This is incredible!!

I really appreciate the time you spent making this video , it helped open my eyes just a little bit farther. Thank You.

I was wondering when u would post a video. This is fast. Good job. 👍🏼

You can tell how moved were this scientist and so I am. What an Amazing achievement!

Another wonderful video from Dr. Brady Haran!

Amazing you're still doing Sixty Symbols videos, brady. I'm watching the "all videos in chronological order" playlist and i'm still in january 2015 after weeks of watching. (Best series ever, beats breaking bad). Thanks for all of this. Hats off!

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!

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.

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.

This is my first time watching your video and I find myself enjoying listening to smart people non stop talking interesting stuff.

Phenomenal job, Brady. Thank you and everyone at Nottingham.

Professor became a lot older since I've stared watching this channel :(

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

Really great video. Thanks for the breakdown.

See also Veritasium’s explanation of what we expected to see based on the physics before the image was published

i always get giddy when stuff like this is announced like when we got those close up on Pluto from the new horizon

Brady, of all the science channels I'm subscribed to, your video on this came out first. You win youtube, I guess. Congratulations.

I was waiting for this video. Thanks for delivering Brady.!

beautiful picture quality, good job Brady

Aliens: **checks off "Found black hole" off requirements to be an advanced civilization checklist**

Great video! I was awaiting eagerly for prof Merrifield’s comment on this matter. He also answered many questions that I had! Thanks a lot!

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 )

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

Thank you Brady!

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!!

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.

I have a big sky map poster in my room that still says "Black hole?" with a question mark.

Got to appreciate the sheer amount of sciencie, effort, hard work, engineering and technology it takes to push the boundaries just a little bit

Profound. Beautiful. I'm so glad I've lived long enough to see this.

"Where we are going we dont need eyes to see"

Blurry images really excites us since we were young

Fast and wonderful video :D Its a privilege to be here to see things our brightest minds have discovered. And to see them for the first time in all of humanity....thanks to all you scientists!

Best puzzle so far! Just astounding.

A truly awesome accomplishment! Big cheers for the team of scientists and engineers who pulled this off and made history!

This feels like a 'Man on the Moon' moment. Great vid. Thankyou.

Love the channel guys. Wow

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 .

Brady, sir, please keep us up to date with the subsequent findings and analytics!

Flat Eathers are going to clip that part of the video where he mentions graphic designers being employed by Nasa lol.

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.

This is the one I was waiting for

You know something is special when it makes physicists go "WOW"

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?

Simply incredible. Congratulations to humanity for advancing to the point where questions pondered about the existence of "Black Holes" have been addressed in a manner where it no longer requires speculation. I have been alive long enough to experience man's first walk on our moon....and now our first image of a natural wonder.... I am so thankful to have been able to see these and so much more in my brief lifetime. Logic dictates that there is much more to discover and I hope I see more achievements by humanity of this caliber!

"Well, there it is." - Jeff Goldblum

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?

Thanks for including me 😊

Well done. Proud of you guys

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.

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!!

Thanks man, really interesting.

I keep tearing up, I'm so happy.

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

If we had placed space radio telescopes in Langrarian points L4 & L5, would we be able to get better resolution?

This is heavy! Great Scott!

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! 👍🏻

People from Andromeda or other galaxies may be watching our Sagittarius Black hole of the milky way aswell.

A blurry image of something exciting is still very exciting XDDD

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.

Well done. Thank you.

When you squint, It looks even sharper.

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.

5:08 When the photo of the black hole is so beautiful that it makes you cry

Amazing video. Even though the slow zoom of the fullscreen black hole picture messed with my head. I had to check twice if the image was actually zooming of if my eyes were tricking me.

All I keep thinking is - I wish Professor Hawking was alive to witness this!

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.

Wow wow wow wow wow nothing but illustrations over and over again and again......That folks is what is truly amazing here..........Thank you.....

The image was actually put together by a graduate student from MIT, Katie Bouman.

if anyone watched the NSF release, some of the early journo Q's were like OMG, hilarity

Excellent interviews and amazing image of a galactic supermassive black hole. Even more amazing is the rate at which astrophysics is progressing.

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 KZfaq: "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.

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!

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

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.

I've always been interested in black holes, and have been re looking into them over the past few months. It's crazy that we just had this huge announcement around the same time. I'm excited to see what kind of discoveries we will make in the coming years now that we have this

Brilliant, down to earth scientifc reaction to the news!!

What is amazing is the total lack of scepticism among the captive laymen.

I wish Carl Sagan was alive to see this image.

Great video

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.

9:48 cute pictures of ponies in the background, there :D

Great to see the nearly peerless Sixty Symbols on this Event. So much more Gravity than many of the other science channels.

Amazing thank you love lights and blessings x

Thank you - that all makes sense.

Are Alice and Bob also there, trying to trick the other to cross the event horizon?

Ok we have seen the black hole, the biggest question, has it seen us?

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

Chuck Norris just came out, and said that the image of this one is similar to the one in his black-hole image collection.

Images like that are priceless. Science backed up by nice pictures can inspire people.
