Darkness Visible: Shedding New Light on Black Holes
Black holes may hold the key to understanding the most fundamental truths of the universe, but how do you see something that’s, well, black? Astronomers think they have the answer. Thanks to a global array of radio telescopes that turn the Earth into a giant receiver, we may soon have the first picture of the event horizon of Sagittarius A*, the black hole at the center of the Milky Way galaxy. And, with the power of math, scientists are going even further, using equations to “look” inside black holes, peering at the central singularity where general relativity and quantum mechanics collide. Join Brian Greene and other leading physicists and astronomers on a journey to make darkness visible.

But since that video has been uploaded, we did get that image of a blackhole that the guy was talking about, it’s as factual as the boiling point of water now. And if you’re going to dispute me, the burden of proof falls unto you my friend so make sure you can back up your claims.

Your side, which would involve a global conspiracy spanning centuries where every single person who ever did any research was in on it, didn’t whistleblow, completely made shit up for what? Federal grants? Every person who ever went to university is a shill? MRI machines are useless, mathematical equations are fake shit drawn up by people with nothing better to do in their lives, and the advancement of science is umm, futile?

These discussions are so enjoyable for people (like me) who are into Astrophysics and Cosmology. There’s nothing better than to relax with a cup of coffee listening to Dr. Greene and other physicists debate and reflect on our current understanding of the Universe.
If you like cosmology you should find out about the electric universe theory. they have a wastly different model to big bang/pure gravity universe hypothesis'. its mostly plasma and electro-magnetic physics and doesn't require dark matter, dark energy or black holes. my old man is a physicist and we have great excurses for and against these two theories. i wish people were more curiouis =)
Same , just that I ingest some THC edibles along.
If you wanted to be nice, you could say the "Electric Universe" is science fiction except they pretend it's science. If you want to be blunt about it, it's complete horseshit.
My hypothesis that Dark Matter is not a WIMP, but maybe is a deformation of space-time by which the curvature of space-time ALONE is the cause of the gravitational effect. Gravity is the consequence of the curvature of space-time. It may be possible that the structure of space-time itself could be warped without the presence of mass. Space-time has been shown to react like a fabric by warping, twisting, and propagating independent of mass. These properties have been proven with observations of gravitational lensing, frame dragging, and now gravitational waves. Fabrics can be stretched, pressured, and/or heated to the point of deformation. Such extreme conditions were all present during inflation, so it is plausible that space-time’s elastic nature could have hit its yield point and permanently deformed. Therefore, if gravity is the consequence of the warping of space-time, and fabrics can be permanently deformed, then a deformation could create a gravitational effect independent of mass. Thus, the unidentified dark "matter" that seems to be so elusive to modern science may not be matter at all but merely warped deformities causing gravitational effects. DM could be a microscopic black hole with no mass at the center... Prediction: Spacetime's elastic property hits a yield point, so only that part of geodesic's "stretch marks" would remain after inflation stopped. These steep gravitational wells would not follow the inverse square law. I am looking for Theorists or Experimentalists to help me develop ways to test this hypothesis. Is there a way observationally to test it’s gravity does not follow the inverse square law?
That some theoretical physicists say hundreds of solar masses of matter are compacted by the weakest of the known forces till they attain dimensions exponentially smaller than an electron is it's own genre of fertilizer science fiction. That 99.998 % of the observable, delectable Universe is composed of matter in a charge disassociated state known as plasma... That plasmas move/behave in specific, organized ways ONLY when under the influence of electric currents.... That electrically active plasmas scale from the tiny spark from your finger to the doorknob to the light year spanning celestial objects observed through telescopes... and that those same incredible forms can be recreated via electricity at the smaller scale in the Plasma Physics Labs... Those are all facts.

@@frmrchristian303 Like Samuel Birley Rowbotham.
I could be mistaken, but I think that is very much the norm within scientific communities. The vast majority are keenly aware that modern science is an extremely collaborative endeavour, and that their own personal effort is only a small fraction of that required for great achievements. And although there's always exceptions, even the most egotistical fame chasers tend to recognise that it doesn't behove them not to emphasise the contributions of their colleagues and peers when given a public platform. Otherwise they'll soon struggle to find any that are keen to continue collaborating with them on future projects! The notion of a vast leap forward, due to a lone scientific genius with revolutionary vision, is mostly a myth perpetuated by Western Media, I believe. They're always looking for someone to elevate to celebrity status, because hero warship plays to our cultural (and, I think, instinctual) desire for individual exceptionalism.

I was listening to this podcast while I sleep and thought to myself, what if the speed of light is not a constant, it does make a lot of sense, what do we observe is a really small fragment and for our perception, the speed of light seems to be a constant, but on a bigger scale it should be loosing speed
Well light is kinda just “built different” but this is a crazy question
The speed of light is only constant in a theoretically perfect vacuum, that never can exist due to vacuum fluctuations anyway, let alone all of the matter that exists within the vacuum itself, or the deformities in the fields. Physics takes the second law of thermodynamics too seriously as it creates nice looking answers to equations, but you have to ask yourself “is there any such thing as a closed system in the universe, for the second law of thermodynamics to even be applied?” The answer, categorically is no. Vacuum chamber walls will effect your experiment. Electromagnetic fields outside of your experiment will effect your experiment. The pressure and density that you conduct your experiment at will effect the experiment. Even black holes emit Hawking Radiation, therefore it cannot be a closed system. Different frequencies of light travel through different mediums at different speeds, which is why we see visible light split when refracting through a prism, and the speed of light was measured “precisely” using mono frequency lasers (that don’t even exist in nature) in visible light. It’s very possible that light has different speeds at different frequencies, but I am yet to see anyone experimentally prove this to be observationally true. We likely do not have an accurate picture of our universe in the present day
The speed of light should be constant through space and time if the laws of physics are constant through space and time

Too bad now your mind is trapped in a prison
I like the theory about Black Holes being stars, but I've never fully set on that theory. I'm glad to see people are still open to these questions.
when a star gets so dense that it can't support its own weight it can collapse and launch its contents into space, this process is called a super nova. what remains of that explosion can either be a black hole or a neutron star (quasar, pulsar, generic neutron). what will determine the difference between a black hole or a neutron star generating is the final "weight" of what remains of the star. if the remains are extremely dense the overall mass and density of the object will be so "concentrated" that it's gravitational forces will pull everything into a single point in space and time, this called a singularity. tl;dr: a black hole is a tiny hyperdense star that is so heavy nothing can escape it's gravitational pull not even light. because of this we were only able to detect black holes by detecting their gravity. Because conventional telescopes use light whenever we point our devices at these "black holes" we can't see anything it's "black"; yet we know that something is there.
@@bryanrx337 Yes, I understand the THEORY.
I used to imagine black holes as interdimensional tunnels connecting universes. Since mathematically 1-9 represents physical matter as an extension of energy, I thought of 10 as the infinitely infinite connection between universes since 90% of our universe is observable and the rest is "missing". So the rest makes up the connection to infinity.
Since there are infinitely infinite infinities or for short I say (I³) the possibility that mass from our universe does not have I³ interconnectivity with all infinities and vice versa is unlikely at least at our dimension in our universe.
I watch these. Don’t understand them but keep coming back and try again 😂😂👍

So plank length strings around the torus at the microcosmic scale are like "fractals" of what happens at the macro scale in black holes.All information is therefore stored everywhere (zero point). Like a shattered mirror reflecting the same surface area as the whole mirror. Intuitively" what goes in must come out" like "what goes up must come down" . Information however complex, has an inverse which has the lowest entropy. Potential for complexity exists at low entropy states, as within the fundamental of a. string with mappings of partials which are unseen directly, hiding the complexity of potential substructures/megastructures. Complexity and simplicity are inextricably connected. Thanks Brian Green. Great and brilliant host star !
57:27 Gravitational waves oscillate perpendicular to the direction of propagation - as the photon does also... Fascinating

So anything and or objects that are pulled in by the black hole seem to pass around the edge of this phenomenon and appear to be sling shot away rather than being swallowed up to never be seen again is the way I have always understood from what I have heard in the past, I find all this very interesting inspite of my own confusion about the whole subject, thank you for sharing and please do more videos.
Well, kinda. As far as the picture of it sucking everything in, this is incorrect. You could safely orbit a black hole and never fall in or be sucked in. However, leaving aside time dilation and just to address your general question, there is a certain area around the singularity itself called the event horizon. This horizon wouldn't have a sign or anything special about it to alert you to its importance, but once you pass it, you will not escape. There's no direction you could travel that wouldn't lead you straight down towards the singularity. What's a singularity? No one knows, the math breaks down. But to avoid a very long winded reply, the general picture that theorists paint at the moment is that as things fall closer to this horizon, it's like all their information smears against its ergosphere, effectively getting in line for its turn to be gobbled up. This information scrambles up and orbits faster and faster to near relativistic speeds, friction builds and heats it to millions of degrees, as it draws closer, most is shot out in xrays from the poles while the rest falls passed the event horizon and ultimately into the singularity. Just to be clear, black holes come in many different forms. Mass, spin, charge. It's hard to imagine a black hole with no spin, but there are equations for it. Simply bc It retains and steals the angular momentum, or the spin, of whatever it gobbles up. What I'm describing would be an active black hole with stellar mass and an accretion disk. If you change these parameters, then what I'm describing would be incorrect. I'm also watering down this picture and leaving out time and the fact that whenever you're talking about black holes, the description of what's happening will depend entirely on the observer. If you watched your friend enter a black hole, to him he'd fall right through the event horizon, to you, it'd take an infinite amount of time for him to do so. He'd go slower and slower and become more redshifted and redshifted and you'd live a million lives before observing him disappear. Or something like that. It's hard to put mathematics into words and I'm rusty on my black hole math bc I think it's total bullshit. If we could even theoretically come up with a way for atoms to become so massive, maybe I could buy it. But space and time are immaterial, you can't building something with things that don't exist.
You'll only get "sucked in" if you cross the boundary, a point of no return, called the event horizon. Where that boundary is depends on how massive the black hole is. More massive means a bigger boundary, but generally relatively close when compared to the mass. If our sun collapsed into a black hole and retained the same mass, it would shrink in size, but other than it suddenly turning dark, it wouldn't affect earth's orbit at all. We would freeze, of course, but we'd continue on in our orbit as if nothing happened at all.
Excellent. Thanks for posting. Most folks don't understand that Physicists are judged by coming up with EXACT solutions to define a given behavior. Not so in engineering. We routinely use linear approximations of non-linear systems that are derived from experiments. EXACT solutions are rare and incredibly complex. (Thus the reason I'm not a physicist and can only admire their work.)
Prof. Greene so enjoyable to watch, choice of subjects are mind blowing so are all guests sharing world-wide.
Good job Brian. You're amazing. :) Keep it up pal. Congratulations, amazing theory, and explainations. I think you're prolly right over a Quantrillion percent. :)
I wonder how deep learning has helped with these projects.
ZERO
Wow, when the theory of everything is published/understood we need Brian to explain it! Brian thank you - a great festival
Read his books and you'll feel like an idiot again.
It's adorable how enthusiastic Dr. Ghez is. I don't remember the last time I was that excited about anything, never mind something that involved so much math!
Her voice was really annoying until I realized what state she was in...and then I understood and am now cheering her on....
Its great to listen so passion in their talk and Im happy she won the nobel price two years after this talk
I absolutely love her! The passion she emanates is so catchy
Watched this from start to finish and it's been one of the best videos I've ever watched on KZhead, Thanks 😎👍🏻🏴
Try the video "Why is time a one way street", that one is truly epic.
I finally get “even light can’t escape”. Amazing.
Nay! Even information can't escape! ... If you throw something in a black hole, every piece of information related to that something will disappear. Even the memory of that something??? I just wonder... Really amazing!
@@71NF they say the quantum information actually remains with the black hole and is later radiated away via hawking radiation
Host greets each guest without introducing them - then they are seated closer to each other than to him.
the pull from the black holes cause ripples in time and space that allow the grid to be able to fluctuate at a constant rate so the portals are opened but not simultaneous but in some geometric pattern wave. measuring the sum of the fluctuations shows the gravitational force of the black holes at the events horizon.
I love all these beautiful video's, Mr Greene. And they make me think a lot. Could it be that a Black Hole is not an object, but rather a whirlpool or vortex in space-time. In that case, we should study the big objects near this whirlpool that cause it to arrise.
What I love about this series and this video in particular, is how it illustrates two things in my mind. One, the access to such brilliant minds and how they think but 2 and as important, imo, that they are just regular nice people at heart and the pinnacle of academia in their respective fields doesn't have to be a turnoff to the populous
12:30 When i see someone asking experts to unanimously agree on something (it doesn’t matter what) i hear Carlos Matos screaming “BIT CONNECT!!!!!!!!” with absolute confidence in his voice.
20:21 “Wasssa!! Wasssa!! Wasssa!! BITCONNECT!!!!!!”
Oh I loved these guests! What an entertaining and incredibly interesting talk! I enjoyed myself very much, thank you so much for sharing! I was kinda yelling at the screen: "We've seen the picture of a black hole! They're 100% real!" 😅
Just a random stoner. Observed how "peaceful" comments are here. Man education is necessary.
random straight edge here, chicken or the eggs really, are comments peaceful bc education? or bc ppl attracted to these kinds of videos are less aggressive or w/e by nature?
Maaruk Jones What would a troll even post here? I guess maybe a comment about the hosts? Maybe these videos just attract more rational people.
A master troll could find something. I'm tempted to re-watch it and start trolling the comment section haha.
deepanshu dhillon same lmfao
I think curiosity has a lot to do with it. Half the audience is probably high AF too, astrophysics talks and docu`s are great to sleep to, get good dreams lol xD
Great stuff thanks to Brian Greene and the World Science Festival. Question could we better probe the nature of black holes with gravitational waves, perhaps seeing how they refract around the black hole.
5am, I found the perfect video to sleep to. Thank you ❤️
The image they produced is one of the greatest accomplishments ever...... I can't wait till we get even better technology and better data.
A night in emptyness of cold space in endless mind. A spark of energy with risky warmth and pleasant bright. This felt like birth of joy, like something really frightned. This rough and tidy piece of undefinity in crafty primal net.
Love your poetry!
Light orbiting around black holes..is awesome..no words to explain the feelings.. great work ..thanks to this platform for these videos
This was an excellent experience. Thank you
It’s amazing to watch this only years later and know that she found that black hole, and I believe he was talking about the now famous first photo of a black hole ever taken. So they both went on not long later to achieve presumably the highest goals of their lifetimes. I wish they made compilations of these times when scientists say “we’re running an experiment to find out…”, then the outcome of those experiments once they’re done. 47:31 Unless this is after, then this experiment also DID detect, for the first time… 49:06 oh there we go. Nice to see one of these talks filled with at least 3 scientists who were involved in 3 incredible moments in science
Andrea Ghez should receive a noble prize.
You're not wrong there.
I love her so much fff
You sent that out into the Universe and what do you know🌌🤾♂️
The Elegant Universe was the first book I read about quantum mechanics. This video is even BETTER. Every moment of it is a joy to watch.
Just finished the book yesterday! Absolutely loved it!
But it's not about QM, Grady, it's about string theory. You might want to read it again.
I love their enthusiasm! Interesting stuff!
Love this video besides the fact that it’s a little old, the question of if they think they exist is of course before photo evidence of black holes had been taken. We know they exist because we have images of them now
Thoroughly enjoyable hour & 46 minutes loved it.
Yes .. good for laugh , though
Great insight on a very interesting, still unknown topic! Love these shows! Great scientists and the host is doing a very good job, too!
b
so, start watching the - thunderbolts project.
This is my #2 favorite KZhead video ever!!!!!! When will she hold a Nobel?
You may already know, but she did!!! On Dec 2020, just some months after your comment
Which is ur number one? Just asking might wanna check it out heheh
Great discussion and very informative info. Now I learned where gold comes from
If gravitational waves were to have a high enough frequency (say, from a binary system of lab-created micro black holes, or from the explosive evapovation of a micro black hole), would individual gravitons then have sufficient energy to be experimentally detected?
Theoretically yes but would require a particle accelerator the size of the solar system or something
wtf was my life before these physics talk, amazing we can get free access to that. Cannot wait for these black hole images to come out! :-O
Inès Mercier look at bananas much?
Education should be free,
Tbh, I expected a little more. I know how much work was being put into this endeavor and how faaaar away this thing ist etc.. I hope we‘ll get some more detailed pictures or even videos of black holes!
Love his t-shirts!!! Great educator. After years of listening I have just about got 50% of General and Special Relativity down! So now, what am I going to do with it?
Build a flying saucer. That’s the obvious answer.
Hes such a genius and great speaker.
These type of discussion s about space and Black holes make me realize that I am an idiot of galactic proportion. But I still enjoy watching them.
Now we have an actual image of one. Fascinating and awesome.
As an ordinary man, flabbergasted is the only word that gets me near what I’m thinking right now. This Gem of a programme installs in me , maybe there is hope for the human race. KZhead thanks and whole gang responsible, just remarkable. Cheers!
Cheers brother

Is it possible to get a high resolution version of the string theory animation bit at 1:29:43 ? That was dope.
I believe that if we could approach even close to the speed of light and punch through the event horizon, the pull of the black hole's immense gravitational waves would have the possibility of propelling us past the speed of light or folding space/time.
It takes more energy than there is in the entire observable universe to make even a grain of sand go at 100% speed of light. You cant go faster than light and you cant escape a black hole. Not with our current understanding of physics.
Go for it. !
That little blip from ligo makes you wonder how often little disturbances like that, occasioned by some catastrophe, go through our bodies completely undetected. My guess is that it’s basically all the time.
prolly where the plague and rona and stuff comes from ha
This program is amazing regarding the knowledge these scientists have worked so hard to bring to the public knowledge.
It surprises me the way people made conclusions by not only telescopes but also predict by means of Mathematics the way our galixies work and seem to race away from each other surprises me
*random stoner...So I just watched this now...it is fascinating to watch and observe some of the brightest minds just converse... it's mind blowing trying to imagine 3mil mph or the vast size of the space ...
Try to imagine the space between protons in an atom comparative to their size. Much more vast than stars in apace.
She is a delightful lady who obviously loves and enjoys her work.
Her accent was so attractive
She also loves her voice
@@roosarobin3383 How dare she talk at a talk which she was invited to talk at.
Haha... He loves doing that little Greene Gallop when he's explaining things. The Saddle Sit is another Greene classic.
Jajaja those are the perfect descriptions.
Don't forget the Brian Bounce, the Physicist Finger Flaps and the Greene Groin Gyration (it happened, more than once!)
@@RooBot Haha. He really digs in doesn't he.
KZhead at 2 am: wanna learn about black holes Me: sure. Me after the video: I must see more before I sleep.
Amazing show as ever Prf. Brian Greene, though I must point out (57:20) that sound waves aren't transverse, they're longitudinal.
Reminds me of the diagram of the Riker equation and what Degrasse said about what happens when a human body goes in a black hole.😎
I believe he called it "spaghettified"
Congratulations to Andrea!!!I watched this video month ago and now I'm back for respect 🎉🎉🎉
The only input I can contribute to this amazing discussion is... I am wearing, Mr.Spock cotton socks. LOL
That was funny 😆 hahahahahaha
One of the most interesting talks ever. Many thanks.
