Have zero education. Not capable of understanding what Brian Greene is talking about. I love the fact that someone could know what he knows, to me, it's like magic or religion except I know it's real. I completely admire these guys who dedicate their lives to explain the universe. I'm a gardener in Ireland. This is all I watch. I think that Brian Greene would sit down with me for a pint and not look down on me for my ignorance but would respect me for my wonder and interest.
I started reading and listening to physics and cosmology lectures about 10 years ago and I didn't understand most of what I read, but what I did understand was intriguing. Don't give up, the more you listen the more you will understand. I'm at a point in time now where I'm really interested in finding more about the mathematics. After all science is about seeking what we don't know . And you know the old saying, the one thing I know for sure is that I don't know
I applaud your honesty and wonder for the universe. The good thing about science is that you don't need a background in mathematics or science to learn more about the universe. There's no end to the books and programs(online or not)that approach science from a beginner's level. I would learn more about science if I could do mathematics, but unfortunately, I have no ability or aptitude for math. I'm grateful for programs like this one, they make science accessible for people like me. I think you're right, people like Brian Greene don't look down on us for our ignorance, they probably would have a pint with you if they had the opportunity.
"thank you for uploading these videos. Even if I'm having a hard night, I just put a relaxing astronomy video on and listen. It always makes my nights go much easier. Thank you!!!"
When I was reading Brian's books back in my 20's I never expected to see him blow up like this. I'm so thankful for this window he provides into scientific topics for those of us who didn't go down that path. What a tremendous dude.
I am a retired biochemist in india but my love now is cosmology.... and all thanks to Brian Green and the World Science festival. How blessed i feel to be able to see and hear all these great scientists. Thank you thank you
If space-time came into existence as infinite at the beginning and has been expanding ever since, that's a real life Hilbert's Hotel example, and we're all living in it.
Happy Friday to our Beautiful universe and all of you. Everyone take a Day to learn about the place we live in. Take some time and show respect for our beautiful, magical, and astonishing universe. Looking forward to this thanks WSF and Brilliant team of people that make this happen!
Wow, kudos to the graphics people! Great visuals. And so well coordinated with Dr. Greene's explanations so that what he is saying advances our understanding of the principle being shown in the visuals. It's not easy to make all this flow so well. And of course the director is always awake and prepared. Well oiled machine and the world is a better place for this work of bringing these topics to the public.
Someone help me to understand where these events come from? When you go to the WSF site, and click on "upcoming events", there's nothing, but whenever a video is posted, you go to "upcoming events", and there it is, posted as if someone went back in time and posted it. Are these events things that one can buy tickets to and attend, or do they mystically appear in the past from a parallel universe? Not annoyed, just wondering who all the people are in attendence and how they got there. It would be fun to attend a live event.
Another thought-provoking WSF video. I try to keep up, but some slip by for a bit. The best part of these videos is that dogma doesn't rule. As far as I am concerned, Dr. Greene is a master of hosting different nuances of given physics disciplines.
The quest to understand cosmic origins is a profound journey into the fundamental questions of existence. By probing the earliest moments of the universe, scientists aim to uncover the conditions that led to the formation of galaxies, stars, and ultimately, life itself. Advances in cosmology, such as observations of the cosmic microwave background and the study of primordial black holes, are helping to piece together the puzzle of how the universe began. As we explore these cosmic origins, we face an intriguing question: How will our discoveries about the early universe influence our understanding of cosmic evolution and our place within this vast, ever-expanding cosmos?
General Relativity and the Quantum Mechanics world still haven't been linked up. While there may be a lot of possible reasons for the weird stuff we're seeing, I think one of the fundamental issues is our lack of a unified theory of physics.
How do you show a three dimensional cube of space curve? Every diagram I've seen uses a two-dimensional "rubber plane" like a bowling ball on a trampoline. Is there a 3D graphic that shows the effect in a volume of space?
For years I have been wondering if anyone has looked at how Galactic time dilatation at the center of galaxy's then trailing off as we look to the outer edge as well as frame dragging that can affect our observations that lead us to consider dark matter. I would love to see the calculations and have someone explain that topic.
Is it possible Traveling in a universe that is spinning in its expansion making every photon take a curved path while waving, to become our default setting for the shortest path, and since we have to collapse it to observe it, we assuming a “straight” path; then when we add the stand alone gravitational lensing amplified by that universal curvature, could it be why it’s appearing as if we need more mass for that outcome?
It's always good to remind ourselves that ancient stories, old theories, or recent science can go wrong. We have to remind ourselves to be humble when we discover new information that dispels our understanding and brings us into a new light. I don't need to feel bad when someone (especially religions) is stuck in the past with old, outdated information. Paradigm shifts always come from ages to ages, that's for sure. Brian Greene is always good as a host!
The relationship between the sun and the planets of the solar system is like the relationship between the pistil and stamens of a flower. So the origin of the solar system is like the growth of a flower from a tree branch.🌷
Spectacular and enriching!!! Dark energy & DM constantly puts everything into perspective as we are receding rapidly away from our cosmic origins/point of creation towards the end of time as space is expanding 😅 while keeping in mind and taking into consideration that observation is key for the deeply hidden realm 😏😅 Looking at the big picture now to gain more insight on our frame of reference starting at the Big Bang and ultimately towards the utmost boundary of our cosmic horizon (end of time). Bound to an eternal cyclical universe we could potentially slip or bounce into another Big Bang probably without noticing or even feeling it 😅 Indeed dark matter and dark energy enhances our common sense and intuition 😅
This is such a great show, I am in my 60ies but love this show... This seems like a link between bare bones science intersecting with some things as abstract as ... soul or energy with a spirituality.. one source of it all.. is there a boundary seperating the real and surreal/imagination, the logic and the intuitive...
I liked the down-to-earth approach of Adam Riess, along the lines "lets see where the data lead us". Disappointed about the "discussion" on inflation. I think Adam has it right on inflation - the "evidence" is at best indirect and we have to keep an open mind regarding our current understanding of gravity (and model-building based on that understanding). Inflation seems more like a fix for an imperfect model, that is (quite obviously) very good at describing the universe's current state (in the range z ~ 1000).
Fluid mechanics is a great way to think about it. Space is a variable neutrino ocean. Vacuum is an effect comes from multiple dynamics. Things such as QCD and the coupling along with effects through a resonating variable field that each change eacother with variation, inverse in nature, but universal under properties. Adding in things like chaos theory, refractional vertices making with fluid like mechanics and dynamics of influence such as the von Karman Vortex streets... ultimately with enough coupling reordering phasing curvature and inverse inputs that at a high enough phase efficiency that space curves enough to invert flow energy in the reaction. We need to understand our own phasing evolution with spacetime, both it outside of us yet phasing in parallels smaller than the Planck length. So things like resonation whips apply, yet as you look from a far enough point you can view refraction patterns and detect wave pressure energy. Either we are the edge of this evolving constant that looks like waves through time and particles at the edge where quantum tunneling properties lead evolution, yet a closed system under repeating values that show patterns in matter and energy. If we aren't the particular point of the "current" ..right now, the present, connected instantaneous with past evolution through refractional reverberations but are the evolving invading phasing pulsating points of multiple resonation rippling coupling sets that have evolved to curve space enough for us to continuely phase through it, but we are actually phasing ourselves as wave partical duality that has evolved to resonating with enough finite energy they appear to be points our elementary particles and the oscillations inbetween with pressure refractional duality
I appreciate Adam put his scientist hat on. We have made many prediction from theories and have been wrong. Like proton decay, blackbody radiation, and magnetic monopole. Let’s find it.
Recently these talks have been too strongly moderated, to the point that it feels like Brian Greene invites guests onstage to read the slides he wrote for them. I much more enjoyed when guests would talk to and even argue with each other, instead of just keeping to Brian Greene's schedule.
I love these videos! Accessible and yet not patronising. Still, I wish there was an educated idiot on the panel unashamedly asking 'stupid' questions. 😀
Love watching these bit high! At a plank scale, quantized space would be horizon like, and a field could have a Casimir like effect pushing those quanta apart. Akin to a single quark not being possible, the new quanta of space arises from that energy, and so on...
I dont think Supersymmetry exist in our universe, but they could exist in another parallel universe next to ours, that could explain the dark matter that gravitationally interacts with matter in our universe but were not able to detect with current instruments due to the supersymmetric particles acting as the dark matter in our universe while they exist in extra dimensions or a parallel universe right next to our Universe.
Try this. It could help explain both the S8 snd and Ho tension. We assume that there is only one universe in the cosmos. It's only 100 years since we assumed that there was only one galaxy in the universe. Imagine our universe in a galaxy of universes. The gravitational pull from those masses would become increasingly more significant over time. The value of Ho would increase over time and the rate of structure formation would slow down. No new physics required. The universe has always been bigger than we thought.
It’s interesting to note that there are some discrepancies in classification of wandering space planets, rouge, planemo, or not quite a brown dwarf. These objects potentially could yield the mother load of discovery just as Teagarden, Gliese, or Trappist exoplanets prove to be awesomely promising for viable habitable biome’s. The microbes most likely aren’t the only forms of extraterrestrial life somewhere out there and in all actuality it’s only a matter of time until a point in space exploration opens up something truly beneficial to humanity, maybe not soon or maybe not later but scientific possibilities are paramount to a self aware, sentient understanding.
Probaby a stupid question but, since we know there is a thing called low background steel (steel made before atmospheric testing and Hiroshima) this must indicate that there is a low level of atmospheric radiation due to the fallout from all the nuclear detonation that occurred back then. How do they distinguish the difference between that radiation and the big bang radiation?
I imagine that it is because the measurements and photo's of the background radiation are always taken Outside the Earth's atmosphere. The type of radiation would depend on the material and its concentration, I am sure that physicists have devices which are able to detect and differentiate between all types-from whatever source.
ya If Brian was not there I am not sure about the skill of these people to explain things they are like the average professor in a class and Brian is a super stars. But for me it is a lot of déja vu since they might have said a lot of the same stories in many of WSF show and other similar show and books...
12:08 If space and time are not physical how can they be bent/warped? 31:59 As photons moved out in all directions what we have here is an infinitely small random sample of the photons that just happened to be in the direction of future earth. I find this sample too small to have real value. [Cont...]
Dear Axle.student, don't be too impressed by the scientific eloquence of the personalities. In the field of speculation they point to theories and nothing more, many of them that swarmed people's brains for decades and literally fell apart, leaving a void, the case of the Big Bang Theory, a tremendous nonsense of 13.7 ( ?) millions of years, as can be seen by observing where the James Webb telescope points. Space and Time are not considered physical entities, strictly speaking, they come from the fact that they are conceptually and purely mathematical entities, (from Classical Geometry to the many abstract mathematical and geometric locubrations and daydreams) because metrically they are of the same caliber, in fact Time it is considered a spatial dimension of order -1 or complex, if it is required to work that way or whatever you want to call it, evidencing Theories of Conformal Spaces, Poincaré group, Clifford Algebra, Conformal Lie Algebra, etc. Start by imagining identifying an open box propagated in all directions with straight lines like Laser light and without limits, where you have placed an appreciable amount of spaghetti, chaotically curved or curled, together occupied by appreciable amounts of conveniently crumpled and intertwined cellophane subject to perforations between each other as if pitcher plant flowers were sprouting from each other or like cabbages. There you have a slightly hilarious idea of Space-Time already occupied, wrinkled/curved by the action of the Matter-Energy/Dark Matter fields of the gravitic interaction between this Existing Matter and Energy. Now take into account the other fundamental forces known so far and imagine the entanglement that could result in successive, functionally or logarithmically smaller scales. The notion of observable, Quantum Gravity,...Spaces or Holographic Universes was left out. Pay attention to your second question, it is worth making the distinction between the cosmological microwave background radiation that is observed in the observable Universe and the local radiation, say a few parsecs of fourth dimension or in a Minkowski space, if you want to call it where condensed matter is scarce (stars, planets, dust).
Good questions from Brian. Very disappointing to hear them not acknowledging that MOND predicts the rotation curves correctly, not needing any dark matter. Also that dark energy is way more farfetched than assuming everything is homogenius in the universe. Other than Brian and slightly Adam, this panel was very closeminded
But they're not asking the one question that I have, which is how the changes in time from the expanding universe affects us. Does our time here on earth speed up or slow down? Are we aging faster or slower? Does it make planet Earth spin faster or slower? What impact does it have on our own little corner of the universe from our planet, to our solar system, to our galaxy, to the cosmic string that our galaxy is a part of.
Since Einstein abolished absolute time - how can anybody say something like "13.8 billion years ago"? "Ago" refers to "now", which DOES NOT EXIST, at least not in a cosmological context! Brian, please explain!
Einstien stated time is RELATIVE-/you can only measure it RELATIVLEY...the present to X(here & now to there and then/13.8 billion years ago) is RELATIVE so I dont see the issue?
Now existed. And when someone says 13.8 billion years ago, they're referring to the approximation of now that existed within the timeframe they said/thought it.
@@r1nger81What we call "13.8 bil years ago". Could that same event also mean something like "8 bil ago" or "21bil ago" for another random observer? Or not?
13.8 is an estimation based on the limit we can detect distant astrological objects due to the speed of light reaching Earth bound observers. Yes, it is a quantum limit that impacts astrological observations. That's all it is. The universe may well be older, but we are limited to what we can sense through our telescopes and our computational math.
With regard to the expanding universe theory, couldn’t it be that only the region we can see happens to be expanding? What I mean to say is the universe is unfathomably large. Maybe the visible portion of the universe for which we exist in has been thrown by the great attractor as we spin around the thing. Maybe if there was a way we could zoom out far enough, and somehow map a much much larger portion of the universe, we would find quintillions of strings and webs of galaxies, spinning around some insanely large black hole we call the great attractor. Nature is cyclical after all. It doesn’t seem unreasonable to imagine this idea of mine could be the way things are. Ah, what do I know? I’m just a music teacher.
I live in Poland and teach English. I have a student who was a physics professor at the local university. He's now an IT developer because he couldn't afford to keep himself and his maths teacher wife. I also have an 18 year old female student who has an "only fans" site which makes her more money than half a dozen university physicists. I struggle to understand the modern world.
The fact that we assume dark matter does not interact with light (it does by altering photon’s path gravitationally), suggests that these dark matter particles are as small and dispersed as they need to be, that very seldom collide with photons if at all, therefore, best explanation is- At a certain point the energy we must put in a collision in particle accelerators would create a self sustaining singularity, so we are limited in seeing smaller particles in the particle soup we can observe or conclude with detectable permanent or short lived particles. What we can’t detect is anything smaller than 1.6x 10^-22. Dark matter
BACKGROUND RADIATION is just distant nonvisible stars (density is more or less the same through the entire INFINITE UNIVERSE) which light is reaching us, but we cannot see them due to our poor resolution and too short time of light collection from one spot in space
Dark energy is with dark matter and they are everywhere and they contain all the information like starting from the probability contained in the field with a fine field
I think that one time when professor brian greene give us in his documentary the entropy equation ho contain w And i think the relationchip with w boson
Scientists and cosmologists have discovered that the most distant galaxies are receding from view at a rate faster than those galaxies closest to us. They made this determination by observing the red shifted light from the distant galaxies and applying the Doppler effect. So they conclude that the galaxies 13.8 billion light years away are moving away from us much faster than those that are only say 1 billion light years away. But are they neglecting time? If we see red shifted light that left a galaxy 13.8 billion years ago compared to light from closer galaxies that is not red shifted, aren’t we observing what happened in the distant past compared to the much more recent past? Wouldn’t the expansion of the universe actually be slowing down, not speeding up? The faster galaxies are much older than the newer, slower galaxies. The fast moving galaxies were receding at the highest speed 13.8 billion years ago. Doesn‘t this actually indicate that the expansion of the universe is slowing down?
Adam is incredibly knowledgeable but also very clear at explaining the information. It’s easy to understand how he won the Nobel award.

12:08 If space and time are not physical how can they be bent/warped?
31:59 As photons moved out in all directions what we have here is an infinitely small random sample of the photons that just happened to be in the direction of future earth. I find this sample too small to have real value.

Dear Axle.student, don't be too impressed by the scientific eloquence of the personalities. In the field of speculation they point to theories and nothing more, many of them that swarmed people's brains for decades and literally fell apart, leaving a void, the case of the Big Bang Theory, a tremendous nonsense of 13.7 ( ?) millions of years, as can be seen by observing where the James Webb telescope points.
Space and Time are not considered physical entities, strictly speaking, they come from the fact that they are conceptually and purely mathematical entities, (from Classical Geometry to the many abstract mathematical and geometric locubrations and daydreams) because metrically they are of the same caliber, in fact Time it is considered a spatial dimension of order -1 or complex, if it is required to work that way or whatever you want to call it, evidencing Theories of Conformal Spaces, Poincaré group, Clifford Algebra, Conformal Lie Algebra, etc. Start by imagining identifying an open box propagated in all directions with straight lines like Laser light and without limits, where you have placed an appreciable amount of spaghetti, chaotically curved or curled, together occupied by appreciable amounts of conveniently crumpled and intertwined cellophane subject to perforations between each other as if pitcher plant flowers were sprouting from each other or like cabbages. There you have a slightly hilarious idea of Space-Time already occupied, wrinkled/curved by the action of the Matter-Energy/Dark Matter fields of the gravitic interaction between this Existing Matter and Energy. Now take into account the other fundamental forces known so far and imagine the entanglement that could result in successive, functionally or logarithmically smaller scales.
The notion of observable, Quantum Gravity,...Spaces or Holographic Universes was left out.
Pay attention to your second question, it is worth making the distinction between the cosmological microwave background radiation that is observed in the observable Universe and the local radiation, say a few parsecs of fourth dimension or in a Minkowski space, if you want to call it where condensed matter is scarce (stars, planets, dust).
@@ricardosaldanha6662 Why are you telling us that you failed in school? ;-)
Good questions from Brian. Very disappointing to hear them not acknowledging that MOND predicts the rotation curves correctly, not needing any dark matter. Also that dark energy is way more farfetched than assuming everything is homogenius in the universe. Other than Brian and slightly Adam, this panel was very closeminded
How did you remove the gravitons from empty space?!
But they're not asking the one question that I have, which is how the changes in time from the expanding universe affects us. Does our time here on earth speed up or slow down? Are we aging faster or slower? Does it make planet Earth spin faster or slower? What impact does it have on our own little corner of the universe from our planet, to our solar system, to our galaxy, to the cosmic string that our galaxy is a part of.
The question about the origin of the universe is superficial because we will face this question every time: What is the origin of this origin?
Wish they dived into alternate theories of origin, like CCC or multiverse
Another version of epicycles maybe? When talking about the two different numbers of expansion rates.
Neil Turok has good explanations of several of the questions raised
WSF is the best show on RUclips.
Brian time is not linear, space is an illusion 🌟
Can vacuum energy inside living things on earth be measured. Bc I see dark energy like the cosmos just growing like a living entity
Since Einstein abolished absolute time - how can anybody say something like "13.8 billion years ago"? "Ago" refers to "now", which DOES NOT EXIST, at least not in a cosmological context! Brian, please explain!
Einstien stated time is RELATIVE-/you can only measure it RELATIVLEY...the present to X(here & now to there and then/13.8 billion years ago) is RELATIVE so I dont see the issue?
Now existed. And when someone says 13.8 billion years ago, they're referring to the approximation of now that existed within the timeframe they said/thought it.
Space is not the same for all observers, time is not the same for all observers, but the spacetime interval is. It is said to be "invariant".
@@r1nger81What we call "13.8 bil years ago". Could that same event also mean something like "8 bil ago" or "21bil ago" for another random observer? Or not?
13.8 is an estimation based on the limit we can detect distant astrological objects due to the speed of light reaching Earth bound observers. Yes, it is a quantum limit that impacts astrological observations. That's all it is. The universe may well be older, but we are limited to what we can sense through our telescopes and our computational math.

You could try modeling these casimir plates with a metric tensor 44:17
I approve
Searching for finite answers and conclusions in an infinite observation, unless we reach the perimeter feedback loop
Do any of the participants know anything about the "Life Force"?
With regard to the expanding universe theory, couldn’t it be that only the region we can see happens to be expanding? What I mean to say is the universe is unfathomably large. Maybe the visible portion of the universe for which we exist in has been thrown by the great attractor as we spin around the thing. Maybe if there was a way we could zoom out far enough, and somehow map a much much larger portion of the universe, we would find quintillions of strings and webs of galaxies, spinning around some insanely large black hole we call the great attractor. Nature is cyclical after all. It doesn’t seem unreasonable to imagine this idea of mine could be the way things are.
Ah, what do I know? I’m just a music teacher.
Dear God, I wouldn't even allow you to teach music after reading this.
I live in Poland and teach English. I have a student who was a physics professor at the local university. He's now an IT developer because he couldn't afford to keep himself and his maths teacher wife. I also have an 18 year old female student who has an "only fans" site which makes her more money than half a dozen university physicists.
I struggle to understand the modern world.
thank you Dr. Greene but alas your guests didn't want to address the final topic.
54:00 Open your mind, the human factor that lies about the x-axis in cosmology is staring us right in the face 😱🪞
It’s a weird feeling (conjecture) that the dark energy-matter may come from extra dimensions with which we cannot directly interact
Our biggest obstacle is our need to compartimentalised
With all seriousness would tardigrades survive a black hole?
Propably
What is the frequency of the original light? You need to know that, and it better be One Single Color.
It is the color of ionized hydrogen shifted by expansion
And what is that? They calculate what? Is there a single number they use or it is all newton and einstein said so?@@davidfannin7187
Fantastic
All started from a cosmic energy, it evolved into multiple energy, theory of evolution follow through, all may continue to infinity.
This conversation would have been more credible if Dr Hugh Ross had been included
9:12 “When the universe was a thousand times smaller than it is today”
She must be referring to the observable universe I guess.
The fact that we assume dark matter does not interact with light (it does by altering photon’s path gravitationally), suggests that these dark matter particles are as small and dispersed as they need to be, that very seldom collide with photons if at all, therefore, best explanation is- At a certain point the energy we must put in a collision in particle accelerators would create a self sustaining singularity, so we are limited in seeing smaller particles in the particle soup we can observe or conclude with detectable permanent or short lived particles. What we can’t detect is anything smaller than 1.6x 10^-22. Dark matter
i read so ma ny books watched so many youtube videos, made so many questions, that I think I know as much as Dr. Greene lol
BACKGROUND RADIATION is just distant nonvisible stars (density is more or less the same through the entire INFINITE UNIVERSE) which light is reaching us, but we cannot see them due to our poor resolution and too short time of light collection from one spot in space
Dark energy is with dark matter and they are everywhere and they contain all the information like starting from the probability contained in the field with a fine field
I think that one time when professor brian greene give us in his documentary the entropy equation ho contain w
And i think the relationchip with w boson
44:50 Have you considered entropy as a tensor?
No. ;-)
Scientists and cosmologists have discovered that the most distant galaxies are receding from view at a rate faster than those galaxies closest to us. They made this determination by observing the red shifted light from the distant galaxies and applying the Doppler effect. So they conclude that the galaxies 13.8 billion light years away are moving away from us much faster than those that are only say 1 billion light years away. But are they neglecting time? If we see red shifted light that left a galaxy 13.8 billion years ago compared to light from closer galaxies that is not red shifted, aren’t we observing what happened in the distant past compared to the much more recent past? Wouldn’t the expansion of the universe actually be slowing down, not speeding up? The faster galaxies are much older than the newer, slower galaxies. The fast moving galaxies were receding at the highest speed 13.8 billion years ago. Doesn‘t this actually indicate that the expansion of the universe is slowing down?
Why do you say? How did the universe begin? Existence may have always existed and we are now just a stage in this endless path
Nothing puts me to bed quite like these talks.
I am crazy but i should create big bang with concerving space time fabric and matter to build microwave background
