Honestly we need more science and scientists to be more on media rather than celebrities! We can just learn so much from watching these videos

But then wouldn’t said scientists in the media become celebrities themselves? 🤔

@Ugo Eze yes which is a better version of superficial celebrities like island boys lol

This is what you're asking for. Most people don't prefer this to what's on television networks. About half of the adult population in the US cannot read and comprehend a book written for 8th-graders.

Y Oooooo h

I agree, but it seems most people want to watch senseless tik tok videos instead

The world science festival with Brian Greene is such an amazing gift

All science aside, this is a really serious interview. Decent, patient, knowledgeable, humble, understanding; unlike interviews we all see on TV with news anchors, where they cut off, brush aside and talk over interviewees. No loud voices, no big languages, no show offs. Obviously, education, especially high education, makes a different class of people.

What class is that?

@Liam Howard If you have to ask then you don't belong to that class.

@No God….and another one ☝️

I find it just liberating how clear, understandable and yet incredibly entertaining you and your guests present your knowledge about everything that has to do with physics. It's so refreshing for my heart and soul to get all this professional content in times with all the flat earthers, lateral thinkers and those who talk about crushing the system. Thank you Brian and your whole Team for doing this great stuff to humanity!

Other than the lateral thinkers (I think I'm one but maybe I can ask you to shed a light first on what you understand them to be?) I wholeheartedly agree with you!! It indeed is amazing and gratifying!

lateral thinkers don't fit into your sequence. lateral thinkers are important to science and technology and problem solving/progress in general

@Robinhund Absolutely. Although at times I have difficulty explaining my thought process to the majority of linear thinkers (not derogatorily used here) and I notice that it is conversely true too, they have difficulty either understanding or transferring their information to me. My fuzzy logic is difficult to translate, and most of lateral thinkers and visual thinkers have their own version so there is hardly any consistent way to learn or translate. Rough ride, but exactly as you state, important for our species and its progress as we cross fields, cross pollinate ideas and build new routes to new areas of any of the topics we set our mind to. Occupational hazard of being a lateral/visual thinker.

The genius of Mr. Green is that he has a wonderful knack for explaining science in a way that the rest of us can understand or at least want to try to understand. He ask simple relevant questions.

We are extremely thankful to you Prof. Greene and all the encredible minds you host in World Science Festival. Please keep advancing our understanding of matters and please never stop. Thank you.

FYI he doesn't read the comments 😅

@Whirled Peas He has mentioned that he actually does.

I was in grade 2, when I distinctly remembered reading a science book about the wonders of the universe, one being a black hole. At that time it was still very theoretical. Im 40 now, and through the years the theoretical turned more into a reality. But when they released these pictures for the first time, I was absolutely in shock. Something I knew for my earlier life as almost science fiction actually exists in full picture thanks to the brilliant work of this team. I think this may be the science achievement of the decade.

These kind of cosmological discussions are absolutely delightful to watch! Thank you Dr. Greene, this channel is one of my best and most favorite subscriptions on YT, and this (I am sure) is the case for many others.

Dr. Green is great. A wonderful science communicator for many years.

@Art Donovan Absolutely 💯

Amazing! Keep up the great work Shep! And what can I say about Brian, just a pleasure to watch videos moderated by you! You guys are the unsung superheroes of our time!

I find it just incredible what the scientists and engineers can achieve. We progress to the stars.

To the stars and beyond…

I am Steve Whitt, Iva, SC USA. I admire Brian Greene

No relation?

@J Ballenger iiooooooooio

@J Ballenger ioooooooiioio

I know this video is about the incredible achievement of seeing the unseeable but I have to do a shout out for Brian Green to be the best interviewer. Respectful, knowledgeable, patient, and inquisitive, he has a set a real high bar in terms of leading such discussions.

Shep and his team literally represents the future of astrophotography. I am incredibly hopeful and excited about what EHT will produce in the future.. This is only the beginning...

Tears were streaming down my face as I vicariously experienced what the team first saw. Thank you!

What an insightful discussion ! impressed by the humility of the guest and sharpness of Brian's questions 👍

Yes! Being a physicist himself, he sure does know right questions to ask. 👍 This is an amazing video! 😊

Oh what a gift this interview was, Brian! I enjoyed it very much, I like how clear the explanations were. To the point, brilliant stuff! 👏

​It is time for Shep Doeleman to, like Andrea Ghez, win a Nobel prize. Also, they are both, like Brian, fun to listen

I remember when they were 1st planning this & just how ambitious it seemed at the time even to a science enthusiast. Great stuff !

Now they are planning a movie of one . That seems impossible too , but they have delivered the photo they spoke off before ....

Any subject presented by Brian Greene is always worth watching. And other than his most recent book (whilst still a great read), all the other books he has written are a MUST read if you're interested in Cosmology and have no scientific background.

Such a great discussion, setting the bar - Thanks Professor Greene

the fact that they're going to have actual videos and pictures of the first disk is insane, comparing it to the black hole in interstellar is a good in my opinion because seeing the thing from the movie in real physical life would be pretty insane

absolotely love it, both what has been achieved sofar and how it is explained here. Brian greene ist just amazing, asking the questions in a way, the public can understand the answers. the virtual background is so well done too. and mr doeleman is a pleasure to hear also, very clear and understandable. thank you for this video. wsf is one of my favourite channels.❤

I love learning that they've been able to use data from multiple telescopes across the world to create higher resolution information than any one of the telescopes can alone. Interferometry has been used for many years at the Very Large Array telescope in western New Mexico. I'm happy to hear that similar technology has been expanded to encompass the world. I can't wait to see future technology increase the aperture of our telescopes to the diameter of the moon's orbit or the Earth's orbit or greater.

Question, what is the sculpture over Ayman 's shoylder,

The future will be a place that none of us are willing to miss.

Fantastic lecture and looking forward to the next discoveries maybe to be developed to better and peaceful species !

Thanks a lot Professor Greene!!!! The event was extremly interesting and I am still totally amazed by your simple but deeply incredible explenation that the force to escape a BH is the same to stay put in time, it is remarcable to me how it gives a simple but powerfull understanding of the Relativity equation behaviour and time-space strong connection.....

Absolutely agree! Thank you!

Fantastic interview! Great questions. Great guest. Great topic. Thank you!

Using advancing computing power to push the envelope on seeing deeper into the cosmos. Outstanding 👍

Thank you for this interesting event! A question about super-massive black Holes at the center of galaxies: which is their possible role in the formation of a galaxy?

I've wondered about it too- I hear it said that super-massive black holes are found at the centre of 'almost' every galaxy, but not heard much elaboration beyond that. I suppose it's an interesting question as to how these things form - I mean if you look at the accretion discs of matter piling up, unable to get in, and the relativistic jets of matter being spewed out, these things are messy eaters, like a baby with an ice-cream, only a small percentage ends up in the mouth, the rest of it just gets sprayed everywhere! So how do they get so massive in the time they've had?

It may be that, when a region of area flattens just enough to create an immense amount of energy, the energy itself collapse inward generating an outward propagation of dark energy. I immagine that black energy, which associates with the acceleration of the expansion of the universe, stems from that very fraction of explosion, a black hole. Therefore, it is the centre where a galaxy expandes.

What came first the supermassive black hole or the galaxy

Like most things about the Universe around us! We have no clue!!!

Excelente reportaje y gran maestría en la exposición de todos los conceptos físicos.

This was really well done. It would be interesting for one of these physicists to do an interview about the dynamics around a black hole. For example what frame drag might mean for a spaceship flying through it, and how frame drag and an object orbiting the black hole might interact. Too many black hole videos cater to novices. I love to see a video that goes a little deeper into the strangeness of a black hole, without getting into too much math. IDK. My thoughts anyway. At the end of the day I guess these videos are for viewership. Maybe that’s why?

The royal institution video about black hole ...very different video

@Vijay Stanleymed thanks Pal.

@Alex Pearson the other end of black hole..name

The production values are so excellent ------- So many sites should use this as their standard.

Yes it is so excellent 👍

I gor tears in my eyes during the discussion. So incredible.

Hi Brian Loved this 👍 Would the energy produced from two blackholes colliding, if harnessed be the amount required to open a wormhole between universes ? Pls answer x

Inspired and absolutely educated by this, thank you 💯💯💯

I love finding new Brian Greene videos that I’ve never seen!! I check every few weeks…and boom! Black holes. Astrum, SEA, John Michael Godier, Event Horizon and V101 are my other faves.

The EHT is truly a marvelous display of technology

One hour. No nonsense. Even though we have more or less known a thing or two about the images by now, this is still exciting to watch.

I seen a black hole in my room back in March of 1986. It was in my room and lasted for a few minutes and gradually got smaller until it disappeared. It was a perfect deep dark black circle. I actually remember it and that week quite well.

I'm Einstein's dad.

@Avo I'm Einstein's dads dad, how are you doing son?

Excellent talk. I hope they continue their success.

I can't believe I sat through an hour interview about a blurry blackhole picture, and enjoyed every moment of it.

Fascinating. Thank you. Just one question. Is it possible for us to redirect the JWT to aim at this black hole and verified these discoveries? 🤔

I am totally entranced with these lectures. Thank you.

Love this topic. I would have asked if we observed SgA; how could we see into the gravity well when we are located on the same plane as the centre and not above? Another question would have to do with the completeness of a 3 dimensional approach to gravity, how can you see into a black hole at all; when gravity would be pulling in from all sides which in my mind, shows a picture, not of of a donut, but a round impenetrable shroud that is pulling photons and matter into the surrounding field; everything from every angle. Lastly, I would say please get some telescope arrays on the moon!!!!

Can't emphasize enough, how good this conversation is. Hope instead of building missiles and nuclear bombs, we channel all our money and energy to this scientific discoveries, inventions and their tools.

Hah! Quit dreaming we would need to hve world peace first

@Spamlogs World peace? Who's fighting?

@Broken Hill Man my imagination

This kind of video editing looks so good in VR 😭 Thank you World Science Festival.

absolutely stunning, as always.

Mr. Green and NDT are among the best educators of EUA.

Question: Is there a point when diving into the rings that space telescopes become an imperative in that you can only seperate the dishes so far on the surface of the planet?

Thank you Brian and the team. ❤️

Absolutely incredible interview!. Thank you.

Just wonderful. A perfect interview. Making me proud to be human. Thanks.

I love how science is catching up with all the universal visions I’ve had. It’s so reassuring.

You must be a genius.

When will you start selling things ZunZenTzu

@KP no just like to travel

@Lawt Colt don’t know how to charge but if ur keep I’ll have a real time conversation about stuff

Keen*

This is one of, if not the best, lecture WSF have done to date. And that is saying something! Awesome!

Great thrill to know about black holes and I think it can explain more about the universe

Spectacular images, which lead the curiosity to wander from the viewpoint - if telescopes were to capture imagery from a sidereal vantage point, what changes? Appreciating the wonderful work that's been conducted to date, but the size of planet Earth in relation to the observed suggests that the data will be limited - not only in clarity but also in content. So from a novice perspective, with 'wild' imagination, emergent questions are: 1. How could a range of telescopes be created to capture imagery from a vantage point sidereal to the black hole? 2. How far beyond (behind) a black hole could a telescopic camera be placed? 3. The double slit experiment shows that a photon can be in two places at once, so can the same be done with a teeny-tiny camera? No apologies for being 'wildly' imaginative Thank you again World Science Festival!

Beautiful conversation. The Netflix documentary on Shep Doeleman is worth a watch as well!

Hi Brian Can a supermassive blackhole only form in the heart of a galaxy ? Or could it also form anywhere in a galaxy ? Thanks pls answer 😄

Would be good to learn about where this rapid acceleration in our expansion in proven knowledge could take us. My hope is some kind of critical mass of enlightenment where we can better look after our species and those we directly and indirectly rely on.

For a lot of us armchair science nuts Mr Greene brings us generational updated fascinating insights into modern day physics. Sorry for lack of comma’s 😅

It's fair to say black holes were predicted by mathematics and confirmed by observations of their gravity affecting the bodies of matter orbiting them. What a wonderful example of the amazing power of maths! (Please note American cousins, Mathematics or maths is plural so saying Math is very annoying to us in the UK! 😂)

The golden ratio must be at play for things like this and total solar eclipses to be so perfect.

I don't know about you but I find it very exciting to think of what's to come in the future; close-up photos, videos, more data on size, etc ! The only painful thing is that I won't be here to see most of all of that. Mortality really sucks the big one sometimes !

What a great interview...!!👏👏👏 I think not only earth but we can put telescopes on other solar system planets like Pluto and convert the whole solar system to a massive virtual telescope to improve the resolution angle thousands times better, but of course this needs a massive funding and improved technology.

Is the distortion in the Earth's upper atmosphere filtered out by each telescope individually or is it done after the data is collected for the black hole's image?

Finally, an explanation of black holes i can understand!! Thank you!

You understood that ?

This people are the real rockstars of our generation. Support them at all costs.

A cannon ball at escape velocity leaves the earth but at a reduced velocity due to gravity slowing its velocity. However, light escaping a near black hole can't slow down or the speed of light would seem to be violated. How is this paradox resolved?

i wish you'll put one dish in our country. fantastic job guys! very inspiring!

It's interesting to me that if ER=EPR a universe could exist inside a wormhole between 2 black holes.

As usual a very interesting session. I wish I knew the title to the music in the end. I could enjoy it all day long...

The question I want to know is, does the event horizon occupy more volume of space or rather grow as it swallows matter

A very smooth and warm interrelation between these two brilliant guys.

According to Hawking black holes can evaporate because some photons can escape from them. But photons that "escape" were never really part of a black hole. And as it was explained in this video there are some photons that are swallowed up and others that are not. I don't think the ones that are swallowed up could ever escape. But in order for a black hole to evaporate whatever it swallowed up would have to escape from it in order for the evaporation to happen. Given the size of M87 there doesn't seem to be any limit to how big a black hole can get or how much material it can swallow. But I seem to remember that there was a threshold size that when reached would initiate the beginning of a black hole's evaporation. Anyway, I would like to see a video about the life span of black holes.

Great show, what makes a black hole spin or not spin? Thank you

Thank you for this valuable context

Seeing is believing...I look forward to Shep doeleman receiving a Nobel prize for imaging a black hole.

I love how this guy has his entire lifetime work pinned on his coat!

Thanks for your time gentleman and all your hard work

Give this guy a noble prize

They should do this technique with satellite telescopes in space and make a virtual telescope way larger than earth.

Geeeeeee What an achievement, and as time passes Einstein brilliant becomes more and more profound

He was always profound...it just took the world 100 years to realise it.

Nice, thank you to not turn your knowledge into dimming star and rather making it shine to the average public.

Wonderful production !

What if we could utilize every rooftop satellite dish in the world? I know there are technical incompatibilities, but imagine the possibilities 📡

Old satellite dishes from the early days of satellite TV are sometimes used as radio telescopes by amateur astronomers.

If I worked for Shep I would be so motivated to go to work every day

Not only is the guest intelligent but so is the host!

I truly LOVE how it's not 100% impossible for the movie, "Star Trek: the Motion Picture," to actually still happen. Go, Vyger, Go! As it should be p.s. close enough to Vyger 6. Let it be

If you enter event horizon at the speed of light, you will appear in another location in universe. However the immense gravity force will cause any mass to reappear in the size of quarks, a dark matter.

If black holes are able to be formed in a very small size . Just as the large sizes . It would mean the CERN creation of such a small black hole. Would then allow a permanent small black hole to continue . No matter how small in scale. The results are just as you have reported here. And makes cern a incredibly dangerous experiment that needs to be better understood before it makes such a event that has much longer life time than a very short period of existence.

Brian Greene is a Genius!

So shouldn't we be able to see the massive and extremely bright accretion discs around black holes when looking with powerful telescopes?

The more i wonder about black holes the more i think we are in one.

Shep Doeleman is an amazing smart person.

Will the James Webb telescope be able to see more than ever before? This wasn’t mentioned and I wonder why?

I strongly believe that on the other side of black holes are other universes. We are inside of a black hole and the star exploding was the big bang and its all connected.

It's a great work! But how can you assure that what you see from the radio telescope is a real black hole?

From deduction ... the stars orbiting the bh have specific orbits that correlate with what would be expected if there was a bh. Supercomputers calculate specifically how the orbits would be .nothing else can cause such orbits.

**** Hi Prof. Greene,. I hope you are keeping well. Looking forward to this WSF event.

He doesn't read the comments 😂

Are there stars where the emitted light escaped to a distance of several light years before being drawn back down by gravity?

Shouldn't being able to track sun orbit 'around' it's sun would have led to finding our black hole?

I can't afford a highspeed camera, but have you ever used such a camera (1.000.000/sec) aimed at the clear night sky, I think you could see light going (about 300.000 km/sec)!?
