Adam is incredibly knowledgeable but also very clear at explaining the information. It’s easy to understand how he won the Nobel award.
"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.
Yeah many of his books ARE BRILLIANT
Yeah, the guy is a legend 💯👍
A discussion as lucid as the great books of physics ever written. Thanks for having it.
I allways think the best scientists have the best analogies for how wrong science can be ,,it brings everyone on board. Adam Riess is brilliant.
Yeah, he is 😊
Brian is a talented guide through these topics.
Yeah , if he was not explaining all these, I would be lost in the physics world

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!
We have this one life to appreciate the grand design of this universe
and also thank you for: This program is part of the Big Ideas series, supported by the John Templeton Foundation
I love the idea of explanations being Just So stories without more evidence. Once you know what those are, the explanation is crystalline.
Yeah, for an idiot like me, it is very crystal clear 😅
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.
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.
Thanks so much for this presentation! Such clarity improved my comprehension where I have so struggled. Great communicators all.
See, he never read these comments
I am captivated with Brian's intellect and humbleness.
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.
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.
Thank goodness we have Brian Greene to translate scientists for us.
My wife and I are so thankful for Professor Brian Greene and his presentation of such important and interesting topics 🙏🙏.
I am also thankful to him
This talks are pure gold. Thank you!!!! Really thank you!!!
Gold is useless at the time of war 😮
Say its plastic.
Never useless 😂
Fascinating. Live long and prosper!
What an intro! I’m thinking these talks are almost as good as it gets. My mind loves this!
Great program. What about the other videos of the events in September? I‘ve been waiting for them for months now.
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...
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?
I am fan for years in world science festival
Thank God for this channel.
Takes the mind off the madness of the world, Ukraine ,Gaza etc...
The issue with the ether is that it is also a part of us but has multiple properties of resonation that obscure it's variable change at small enough levels with high enough multiple inputs, coupling, turbulence, and fluid mechanics eventualy it phases resonation to curve space so far that anything effected by it is stretched to obscurity which appears as both there and not there (the uncertainty pricple, SCHRODINGER.. the threshold is that to get to see things this variable or thus finite you have to catch up it in curved time. So to curve that small is the same as curving to obscurity.. as we deem lightspeed the fasted mode for human observation, the space that fine takes so long to shrink that far that the light we would need to send thats fast enough to catch up to it has a wavelength that doesn't confine to that space and creates a black hole. A magnifying effect that we see as a laser because lasers are concentrated enough to curve entropic resonation into inverse flow rippling with turbulent vertices with enough energy input concentration to invert into duality and back around inversely to positive gain over systematic orientation
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.
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.🌷
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.
What is the name of the concluding score and who may have composed the same?
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
The discrepancy in measuring the expansion rate of the universe (67 vs 73)...could it be that the Universe is expanding at an increasing rate?
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?
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 😅
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.
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!
This is applicable 😊
Always informative. And speakers are always interesting n ultra smart
The production quality is awesome!
I love these livestreams
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...
Thank You = = Excellent.
America needs a president like this man. Brian needs to hurry up and solve string theory so he can run for office.
I can’t understand that we can be so sure of what the data tells us means. For example I would not be surprised in an infinite big universe all objects will look as they go away from you over time.
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.
I really hope we humans encounter intelligent extra terrestrials soon, so we can compare notes on cosmology, deepen our collective understanding, and eventually draw out some definite conclusions on the existence of the universe. After all, it is the undefined vectoring pathway we are on into the future.
Our biggest obstacle is our need to compartimentalised
Yeah, Brian Green is a legend for sure 💯👌👍
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.
A Very interesting Video 👌🏻👍🏻

How did you remove the gravitons from empty space?!
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.
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.
Brian time is not linear, space is an illusion 🌟
So good!
Fantastic
Another version of epicycles maybe? When talking about the two different numbers of expansion rates.
Wow. A huge thanks to all of you for doing this.

And i think the relationchip with w boson
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?
That was beautiful. Thank you.
Can vacuum energy inside living things on earth be measured. Bc I see dark energy like the cosmos just growing like a living entity
❤ love it!
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.
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.

Hello from Yorkshire ENG UK GBR £ 🏴🇬🇧 the cosmic origin
i'm up here in Scotland ,and our black pudding, is better than yours!
@@jsnedd66 Nothing like a Yorkshire pudding 😂
I love these videos! Accessible and yet not patronising. Still, I wish there was an educated idiot on the panel unashamedly asking 'stupid' questions. 😀
Do any of the participants know anything about the "Life Force"?
I am crazy but i should create big bang with concerving space time fabric and matter to build microwave background
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.
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
It’s a weird feeling (conjecture) that the dark energy-matter may come from extra dimensions with which we cannot directly interact

Nothing puts me to bed quite like these talks.
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...
Funny they have an Adam & Eva in this Genesis 2.0 as well 😅
All started from a cosmic energy, it evolved into multiple energy, theory of evolution follow through, all may continue to infinity.
With all seriousness would tardigrades survive a black hole?

Stories are powerful tools used to control minds.
The title of this though 🤯🧲💖
Zero is the most important number in mathematics and is both a real and an imaginary number with a horizon through it.
It's geometric counterpart zero-dimensional space is the most important dimension in physics and is both a real and an imaginary dimension with an event horizon through it.
Black holes are ten-dimensional:
Zero is the only number with a horizon through it.
Zero-dimensional space is the only dimension with an event horizon through it.
So, has to include a 0. Got it.
0 and 10 are the first two times we encounter zero in the natural number system (1-9 are nonzero numbers). Their geometric counterparts 0D (quantum) and 10D (cosmological) would then be the event horizon boundaries of this side of the mirror universe.
[2D is not the center of the universe,
0D is the center of the mirror universe]:
The mirror universe theory is based on the concept of parity violation, which was discovered in the 1950s. Parity violation refers to the observation that certain processes in particle physics don't behave the same way when their coordinates are reversed. This discovery led to the idea that there might be a mirror image of our universe where particles and their properties are flipped.
In this mirror universe, the fundamental particles that make up matter, such as electrons, protons, and neutrinos, would have their charges reversed. For example, in our universe, electrons have a negative charge, but in the mirror universe, they might have a positive charge.
Furthermore, another aspect of the mirror universe theory involves chirality, which refers to the property of particles behaving differently from their mirror images. In our universe, particles have a certain handedness or chirality, but in the mirror universe, this chirality could be reversed.
Leibniz or Newton:
Quantum mechanics is more compatible with Leibniz's relational view of the universe than Newton's absolute view of the universe.
In Newton's absolute view, space and time are absolute and independent entities that exist on their own, independent of the objects and events that take place within them. This view implies that there is a privileged observer who can observe the universe from a neutral and objective perspective.
On the other hand, Leibniz's relational view holds that space and time are not absolute, but are instead relational concepts that are defined by the relationships between objects and events in the universe. This view implies that there is no privileged observer and that observations are always made from a particular point of view.
Quantum mechanics is more compatible with the relational view because it emphasizes the role of observers and the context of measurement in determining the properties of particles. In quantum mechanics, the properties of particles are not absolute, but are instead defined by their relationships with other particles and the measuring apparatus. This means that observations are always made from a particular point of view and that there is no neutral and objective perspective.
Overall, quantum mechanics suggests that the universe is fundamentally relational rather than absolute, and is therefore more compatible with Leibniz's relational view than Newton's absolute view.
What are the two kinds of truth according to Leibniz?
There are two kinds of truths, those of reasoning and those of fact. Truths of fact are contingent and their opposite is possible. Truths of reasoning are necessary and their opposite is impossible.
What is the difference between Newton and Leibniz calculus?
Newton's calculus is about functions.
Leibniz's calculus is about relations defined by constraints.
In Newton's calculus, there is (what would now be called) a limit built into every operation.
In Leibniz's calculus, the limit is a separate operation.
What are the arguments against Leibniz?
Critics of Leibniz argue that the world contains an amount of suffering too great to permit belief in philosophical optimism. The claim that we live in the best of all possible worlds drew scorn most notably from Voltaire, who lampooned it in his comic novella Candide.

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.
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
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?
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 approve
thank you Dr. Greene but alas your guests didn't want to address the final topic.

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
GRAVITY is just an UNCOMPENSATED POSITIVE CHARGE OF NUCLEUS/PROTONS
The comments under these videos are always filled with people cosplaying as anonymous geniuses talking about "ah, but the dark matter spins! so you see, there could never be a cosmic singularity! it's just like when a duck swims in a pond, i hav found" and I'm absolutely here to read it.
What if space isn't what we think of it what if dark matter was like the skin of bubbles what if the universe was a constant expansion of bubbles each galaxy a new bubble and dark matter like the glue that holds all the bubbles in an order
With the bubbles expanding and reproducing
Once a photon has been detected in a double slit experiment, all of its energy has been dissipated and is no longer available to the wavefront. Wallah! The problem is solved. If any one has a better answer, please share.
I really enjoy watching these videos. It has to be said that It doesn't matter how many times string theory is plugged. It's still what it is. Beautiful math but non science.
