I agree but, be very careful pointing it out or praising it lest someone see the "VALUE" in it and start pinning a price to it. It seems to be the way of things and what happens to every damned thing else eventually.
Mr. Brian, please keep this channel free and keep regularly uploading the videos. I am not a science student but I'm a huge science enthusiast. I have been regularly watching your videos and learnt so much about our universe and its element, despite being outside the field of science. My billion thanks to you. Please continue the good work. 🙏
Jesus Christ if John Hockenberry keeps interrupting the scientist I'm going to shoot my fucking monitor! Why does he think he need to clarify each scientists statements? He feels he has to explain what the LHC is? There's probably only 10% of the audience doesn't know what that is. I don't think you need to interrupt the scientist explanation to clarify or elaborate things that he thinks the audience might not know. I actually think Hockenberry is interrupting because he wants to feel important and to let everyone know that he understands this stuff. I wish he would just shut up.
I play these WSF videos on my phone almost every night while I sleep. My dreams are filled with people talking about astrophysics and cosmology - Whatever the real physicists are saying in the videos becomes the dialogue in my dream, interwoven with my natural dream motifs. It's amazing, I can hardly imagine not listening to them in my sleep now.
Wow I decided to watch this after an evening of expanding my mind 🍄 and it was a nice kick off to the show to say the least this guy appreciated it. Timing was everything on this one. Thank you for another gem universe.
@Tobi Wobi capslock implies dumbness, especially when so obviously is the answer to the question you posed inferred in the comment to which you replied...
This is the second dance I've seen during a World Science Festival discussion. This is also the second time I've been absolutely impressed, inspired, and mezmerized by a dance piece during a World Science Festival discussion. Amazing!
"There's nothing that impossible about there being extra matter. It's just that we don't know what it is" We just can't see it, measure it, touch it, weigh it, create it or destroy it. What's so impossible?
Light thinks it travels faster than anything but it is wrong. No matter how fast light travels, it finds the darkness has always got there first, and is waiting for it. Terry Prattchet
let me just be the one to say, thank god dark matter and energy is hard to see. because if it wasn't we would know nothing about the universe. because we would be shrouded in a blanket of something that we cannot see through!
29:30 I think it is more accurate to say: The only reason it could be moving at that speed is that there is a force that has no visible explanation. The generally accepted theory is that only some unseen mass could be the source of such an unseen force. So hence we have 'Dark matter'. From Einstein, we know that E = mc^2, not the complete equation ... my hypothesis of MOND which I haven't seen any research about is rotational kinetic energy. E_rot/c^2 = (1/2*(moment of inertia)*(angular frequency))/c^2 = 'Dark_mass' 'Dark energy' is the term we use to talk about the physics that is causing the measured expansion of space. We cannot see the process causing the expansion and it involves a change in energy. Work = (force=mass*acceleration)*(distance) = Change in energy. It is the distance between galaxies that is measured to be changing.
If dark matter is made of particles then what is between those particles? And what are then those particles made of? It's funny to think how far does the rabbit hole continue, and is it perhaps possible that it goes on and on forever? That reality is actually infinitely full of new questions to be asked, new stuff to be found and new levels of existance to be discovered, and it just goes on and on forever.
"...between..." - Gravity. "...made of?" - We don't know. Not baryons at any rate. Not a single jot nor tiddle points towards a "god" at any rate, we're maximally certain of that.
I believe dark energy is a positive pressure exerted by the vacuum energy of space-time, and that what we are calling dark matter is merely the effects of dark energy on regular matter. A positive pressure exerted by space-time's vacuum energy predicts; -the accelerating universe -the expanding universe -we should measure there to be more mass than we can see matter being accountable for -matter in the center of a galaxy / cluster should have added relativistic mass, increasing its gravitational attraction, as well as its escape velocity -matter in the outer regions of a galaxy / cluster should be moving faster than we predict, sometimes faster than our predicted maximum orbital speed without flying out of orbit.
My novel hypothesis that dark matter is just distortions in spactime by which the curvature alone is the cause of the gravity. Spactime has been observed to react like a fabric by warping, twisting, and propagating waves. These properties have been proven with observations of gravitational lensing, frame dragging, and recently gravitational waves. Fabrics can be stretched, pressured, and/or heated to the point of deformation losing elasticity. Such extreme conditions were all present during inflation, so it is plausible that spacetime’s elastic nature hit its yield point and deformed. Therefore, if gravity is the direct result of warped spactime, and fabrics can be deformed, then a deformation of spacetime could create a gravitational effect independent of mass. Dark matter may simply be a particle of the spacetime’s structure, instead an exotic particle sitting in spacetime causing the warped geodesics.
Well, dark matter was definitely not present during early universe inflation, the CMB is as straight/smooth as it gets, so even if dark matter were just deformations in spacetime, they had to have happened much later.
@The Truth of the Matter GR has been virtually infallible for +100 years, I think saying "it must be wrong, somehow" is the cop out, not the other way around.
@The Truth of the Matter It had been virtually infallible in everything it described, and almost everything it predicted, so unless you think it's a theory of everything, I'm not sure what you're referring to? Incomplete, perhaps, but fallible? Also, its incompleteness can't (easily) be blamed for the existence of dark matter, and you haven't exactly presented a good case against either (GR or dark matter), beyond "I don't believe in dark matter, therefore relativity is wrong/needs modifying", which is not just bad science, it's bad reasoning.
Is it possible that we do not fully understand gravity? I know that we do not understand the role of gravity at the quantum level, is it possible that Einstein's explanation of gravity is not fully understood despite the sarcasm of some of the scientist's on the platform. After all, science is an ongoing study of things and they all swore by Newton for a few hundred years
There are 45 items you could listen to here. Each talk is over an hour long. Most of them are an hour an half, thats over 200 hours of listening. I wonder if anyone has ever listened to all of them.. Amazing!
1:41:23 I live in Missouri, and I already believe in the theory of Dark Matter as it stands. Of course nothing is certain but I see no reason to doubt it yet.
"are we believers, are we believers in dark matter and energy?" I guess this is the type of science that takes on a faith element... one thing I've never been good at is faith, you know what we really could use would be some facts and evidence... thank you
The acceleration of the expansion of the universe is observed it's not a question of faith or even a hypothesis, the acceleration is what's called dark energy. Dark because we don't know what causing it, and energy because it's an acceleration. Astronomers have recently discovered a galaxy that does not have extra gravity, no dark matter, the speeds of the stars are according to Newton's law, another observation that supports the hypothesis of the existence of dark matter and in this case the absence of it. I think you are confusing religious faith and belief in a scientific hypothesis based on observations. It is perfectly fine to belief in a hypothesis, in the end science will correct it self. If you don't like faith don't be a like a puritan!
the Dark Energy premise is closer to respecting the idea of a consiousness universe. weather you visualize a pushing gravity or a mysterious substrate fluid, you need to FIRST PERCEIVE THAT THE UNIVERSE IS AN ALIVE RESPONSIVE PHENOMENON THAT PERCIPITATES MULTIPLE "NOW'S". dark energy is an idea that allows us to cope with our own limited perception. we are observing a latency of agrigate animation of a living responsive culture (life system). responding to and from beyond time, because it is conscious. the universe is like a huge creature living in multiple versions of "now". until you see the greater whole the pieces will not make sense.
@Cole D dark matter is ignoring the greater challenges of valuing how consiousness is perceived. their conservative inquiry will support many careers. dark energy is taking a chance in a more realistic direction, but they inevitably must cling to an inadequate paradigm, if they want continued granting. self mastery (mind and body) will be absolutely necessary for any real breakthrough in our species's understanding of reality. Something like schroedinger meets spoon Bender type of experiments.
I'm not a scientist. So maybe that's why I don't understand what or how that dance is related to dark matter. Is it just that there are ppl in velvet black suits making the glowing green bits move. Im kinda hoping there's more to it then that.
These WSF panel presentations and their discussions are so enjoyable. I can't get enough. IMHO the issues surrounding dark matter/ dark energy, as well as discovering just what they are (or are not) exactly, are the most fascinating in physics and cosmology today. I actually like the moderator's humorous style. Within the obvious constraints of his role he does a pretty good job. I do wish he would interject himself less but it's plain to see that occasionally he has to direct the panelists out of the weeds. On the other hand in every one of the panels that I have seen him moderate he is compelled to throw in the occasional tendentious political commentary. While his habitual bias and bigotry are customary in his profession it is surprising that a journalist is so misinformed on the subject. Then again, perhaps not.

(I am a woman) I LOVE Brian Green! (His mind okay) Thankyou so much for these priceless talks regarding the deepest questions of our existence. Wonderful thankyou for this.
When I hear about interesting things about the universe, it excites me and motivates me to learn more about it. But the voice in the video made me fall asleep without even realizing it
I have a question, at 35.17 the picture shown is of a cluster, so turn the image 180 degrees (like it should be) and you will see how mass pushes down on space/time, correct?
I inhabit the realm of the social sciences by profession and I hated taking the "hard sciences" in school, but I love watching physics videos. Astro/particle/theoretical/quantum is so badazz. Thanks WSF!
It was really good wasn't it! . I thought it emphasized the relationship between the seen and unseen brilliantly. The dancers being the dark matter and energy and the glowing parts representing the little bit everything else is! A point which seems to have eluded a lot of people
Geoffrey Zoref one side thinks that classical physics formulas can be augmented with more conditional terms, another side wants to scrap those kludgey interpolations and make up total hacks.
I don’t know how he/they does it… but these World Science Festival Vids are fantastic..,, This one arguably more than most. They make me feel so inadequate and exhilarated simultaneously.
I'm pretty convinced by now that there is a huge possibility that our reality, might be completely auto-generated and even, (if you believe the holographic universe theory is correct) our universe is a "computer simulation" and I put that in between quotes, because computer simulation is a terrible name for talking about things like these, because it is just a metaphor, for saying that there might be an underlying code that the universe and the multiverse and everything either take into account or somehow reality has a way to generate itself. I don't know how else to explain it, but maybe physics and physicists are not "discovering the underlying truths of the universe" but instead they only discover some random laws that gave birth to our universe where other universes might have completely different set of rules and at the end everything might be auto-generated into a "supercomputer"
Interesting prospect. Perhaps, if we are ever able to understand antimatter sufficiently, it will be somehow related. Or maybe not, idk. Just a random thought.
My Theory of Time Has anyone ever wonder, how they come up how with how many years the Universe or anything has been in existence? Well I do! We tell time by calculating how long it takes the Earth to spin one full rotation on it's axes, which we formed time measures for call seconds, minutes, hours and days. We also formed a time measure how long it takes the Earth to revolve (orbit) around the Sun once and call it a year. There is another time measure we formed and it's call a month. A month is a unit of time, used with calendars, which is approximately as long as a natural period related to the motion of the Moon; month and Moon are cognates. The traditional concept arose with the cycle of moon phases; such months (lunations) are synodic months and last approximately 29.53 days. it's in a class by it's self. Anyways, the time that we live by is off. We measure our time according to the Earth, called an Earth year. The Earth is in a stable orbit around the Sun. In it's creation, The Earth's orbit was unstable and all over the solar system due to cosmic collisions. There were about a hundred planets in our solar system before the Earth settled down as it is now, therefore, the Earth was always getting knock out of orbit, recaptured by the Sun into another orbit. So how can we tell the age of anything based on Earth years when the age of the Earth is incorrect? You can't carbon date anything and place years behind it as it's time unit, because again, a year is how long it take the Earth to revolve (orbit) around the Sun. The Universe is thought by scientist to be 13.8 billion years old. How is that when the so called Big Bang happened around 13.8 billion years ago? The Universe and the Big Bang are not the same! The Universe was already there. If we took everything that we know to exist in the Universe out, I mean delete it all, Galaxies, Stars, Planet, ect... what would be left? The Universe, right? The Big Bang happened in the Universe! Therefore, one can never know the age of the Universe, because one will never know the age of GOD. This is my Theory of Time. Thank you for reading, I hope you got that, GOD is Time! It takes Him for any and everything to exist!
I thought DM computer simulations were the only ones really successful, just because it is impossible to emulate the behavior of spacetime curvatures on computer simulations. So why don’t they simply say they use DM as a substitute for gravity waves and space curvatures?
When it comes to galaxies, I prefer the Electric Universe's explanation. "Dark matter" isn't necesary for maintaining a galaxy's rotation...Just the electro-magnetic force. They've done experiments in a laboratory that clearly show that their theory might be right. Check out the "Primer Fields" by David LaPoint, here on RUclips.
Don't come here with your electric universe propaganda we all know that your studies are flawed! You guys give science a bad rep! Instead of arguing for your fancy 'mordern' hypothesis maybe you could support real science that more people consider be good for our society. You divide science instead of supporting our theorys, you make it harder for people to belive in pur science with your alternative hypothesises. Please don't poison science with your new-age thinking and mordern ideas.
It was a different weird, i couldnt make out the dance theme, dark matter as headless- stomachless entities, arms and legs float about like serpents and swans, & thankfully finished.
The Fermi Paradox explained. There is a beautiful loving Universe many people claim they experience when they are undergoing an NDE. Long before any Advanced Civilization gains the technology necessary for Interstellar Travel - they find a way to escape to that Universe. In other words, it is technologically easier to get to that other very pleasant and safer place, than it is to develop the Type II Civilization Technology necessary for Interstellar Travel. This explains why we have found no sign of an Advanced Alien Civilization anywhere in the Universe.
It's really remarkable that this three women represent the top scientist in the Physicist investigation, no wonder we are actually discovering more and more amazing things about our mysterious universe than ever before 💪😁
Since everything in the universe rotates, I think there is nothing to keep the universe its self from rotating, thus creating a sintrifical force that is pulling the universe apart. As the size of the universe increases so do the force pulling out due to the rotation. Would that explain dark energy. If this make seance to anyone I akso have some thoughts on dark mater as well.
To think we are approaching the 10 year prediction mark and neither a dark matter nor dark energy theoretical understanding is any closer. It is all the more reason to believe that when physics finally breaks through, the theory and explanation will have profound meaning to our cosmological reality.
Actually, for a change! I really enjoyed that! great format! Great Science, I was hoping for answers sooner rather than later, but the reality of the situation is just as expected, with some awesome problems to solve.
I may have missed it, but did they say whether they considered the cumulative mass of all the stuff as we move further away from the centers of galaxies, including stellar black holes and objects too faint to show on telescopes? Did they consider the interlocked movements of moons, planets, stars, star systems, etc., and how each drags the other and is itself being dragged? No wonder they all go at pretty much the same speed when they are connected like the cars of a train ... maybe!

(I am a woman) I LOVE Brian Green! (His mind okay) Thankyou so much for these priceless talks regarding the deepest questions of our existence. Wonderful thankyou for this.
The way this commentator finesses his stage commentary ability is bar none top A grade 😅... Bravo
This is a really really good science festival😁👏👏👌 For me one of the best ones👌👌
When I hear about interesting things about the universe, it excites me and motivates me to learn more about it. But the voice in the video made me fall asleep without even realizing it
Guys, science needs to be more in the forefront of our society. Ty and goodnight
instead of having this an hour long, just have vsauce do a video about it lol
Excited to hear about the findings of the JWST in regards to dark matter and dark energy
"Don't Go To The DARK SIDE, Luke"
I have a question, at 35.17 the picture shown is of a cluster, so turn the image 180 degrees (like it should be) and you will see how mass pushes down on space/time, correct?

I inhabit the realm of the social sciences by profession and I hated taking the "hard sciences" in school, but I love watching physics videos. Astro/particle/theoretical/quantum is so badazz. Thanks WSF!
Brian is the most accomplished person on the stage. But he can't get a word in edgewise
But the moderator took a quarter of the time.
Loving this episode tremendously!
Wow, that is so cool they included the interpreted dance. Really caught me by surprise. And quite enjoyed it.
It was really good wasn't it! . I thought it emphasized the relationship between the seen and unseen brilliantly. The dancers being the dark matter and energy and the glowing parts representing the little bit everything else is! A point which seems to have eluded a lot of people
Great presentation & no adds!
It's all about finding the truth. 2 thumbs up
Brian Greene is THE MAN!!
But the alternative may be that Physics as we know it may be wrong.
Exactly! Finally a proponent for flat earth.
***** Got Milk?
I got chicken legs too but I don't tell anyone
in fact there are many examples in history mankind was wrong why not also in this case ? ;)
Almost certainly the case.
Wait, what's up with the pro Dark Energy Pro Dark Matter? They're not mutually exclusive.
Geoffrey Zoref one side thinks that classical physics formulas can be augmented with more conditional terms, another side wants to scrap those kludgey interpolations and make up total hacks.
I don’t know how he/they does it… but these World Science Festival Vids are fantastic..,, This one arguably more than most. They make me feel so inadequate and exhilarated simultaneously.
I'm pretty convinced by now that there is a huge possibility that our reality, might be completely auto-generated and even, (if you believe the holographic universe theory is correct) our universe is a "computer simulation" and I put that in between quotes, because computer simulation is a terrible name for talking about things like these, because it is just a metaphor, for saying that there might be an underlying code that the universe and the multiverse and everything either take into account or somehow reality has a way to generate itself. I don't know how else to explain it, but maybe physics and physicists are not "discovering the underlying truths of the universe" but instead they only discover some random laws that gave birth to our universe where other universes might have completely different set of rules and at the end everything might be auto-generated into a "supercomputer"
Is it possible that a particle formed that gravity has the opposite effect on?
Interesting prospect. Perhaps, if we are ever able to understand antimatter sufficiently, it will be somehow related. Or maybe not, idk. Just a random thought.
Brian Green such a good host
My Theory of Time
Has anyone ever wonder, how they come up how with how many years the Universe or anything has been in existence? Well I do! We tell time by calculating how long it takes the Earth to spin one full rotation on it's axes, which we formed time measures for call seconds, minutes, hours and days. We also formed a time measure how long it takes the Earth to revolve (orbit) around the Sun once and call it a year. There is another time measure we formed and it's call a month. A month is a unit of time, used with calendars, which is approximately as long as a natural period related to the motion of the Moon; month and Moon are cognates. The traditional concept arose with the cycle of moon phases; such months (lunations) are synodic months and last approximately 29.53 days. it's in a class by it's self. Anyways, the time that we live by is off. We measure our time according to the Earth, called an Earth year. The Earth is in a stable orbit around the Sun. In it's creation, The Earth's orbit was unstable and all over the solar system due to cosmic collisions. There were about a hundred planets in our solar system before the Earth settled down as it is now, therefore, the Earth was always getting knock out of orbit, recaptured by the Sun into another orbit. So how can we tell the age of anything based on Earth years when the age of the Earth is incorrect? You can't carbon date anything and place years behind it as it's time unit, because again, a year is how long it take the Earth to revolve (orbit) around the Sun. The Universe is thought by scientist to be 13.8 billion years old. How is that when the so called Big Bang happened around 13.8 billion years ago? The Universe and the Big Bang are not the same! The Universe was already there. If we took everything that we know to exist in the Universe out, I mean delete it all, Galaxies, Stars, Planet, ect... what would be left? The Universe, right? The Big Bang happened in the Universe! Therefore, one can never know the age of the Universe, because one will never know the age of GOD. This is my Theory of Time. Thank you for reading, I hope you got that, GOD is Time! It takes Him for any and everything to exist!
I thought DM computer simulations were the only ones really successful, just because it is impossible to emulate the behavior of spacetime curvatures on computer simulations.
So why don’t they simply say they use DM as a substitute for gravity waves and space curvatures?
How about this? Galaxies radiate spacetime in the form of gravitational waves, which is what is adding more space between the galaxies?
Love you Brian Green Sir .and WSF....Lot of knowledge with great fun and great people..
Good presentation. Much to decipher.
When it comes to galaxies, I prefer the Electric Universe's explanation. "Dark matter" isn't necesary for maintaining a galaxy's rotation...Just the electro-magnetic force. They've done experiments in a laboratory that clearly show that their theory might be right. Check out the "Primer Fields" by David LaPoint, here on RUclips.
Don't come here with your electric universe propaganda we all know that your studies are flawed! You guys give science a bad rep! Instead of arguing for your fancy 'mordern' hypothesis maybe you could support real science that more people consider be good for our society. You divide science instead of supporting our theorys, you make it harder for people to belive in pur science with your alternative hypothesises. Please don't poison science with your new-age thinking and mordern ideas.
That dance was absolutely beautiful!
32:16 Gravity doesn't bend light. Gravity bends space time and light follows those curves.
The moderator interrupts the experts too frequently.
He was high on cocaine...but yes
Every vid they have its all he does
Hannah Fyre would be a better moderator/lay language translator.
@@DemandAlphabetBeBrokenUp lol I was thinking that too
I think he is doing well and he asks the questions that I would ask
I really wasn't expecting one of the coolest dance numbers ever when i started this video.
It was a different weird, i couldnt make out the dance theme, dark matter as headless- stomachless entities, arms and legs float about like serpents and swans, & thankfully finished.
I watched it again at speed x2.. you R right it was very cool...
What if time is dark energy?
The Fermi Paradox explained. There is a beautiful loving Universe many people claim they experience when they are undergoing an NDE. Long before any Advanced Civilization gains the technology necessary for Interstellar Travel - they find a way to escape to that Universe. In other words, it is technologically easier to get to that other very pleasant and safer place, than it is to develop the Type II Civilization Technology necessary for Interstellar Travel. This explains why we have found no sign of an Advanced Alien Civilization anywhere in the Universe.
the dark side of the universe is ruled by the sith..
Amen.
It’s a trap!
It's really remarkable that this three women represent the top scientist in the Physicist investigation, no wonder we are actually discovering more and more amazing things about our mysterious universe than ever before 💪😁
I dunno, because the first 2 ladies behave awfully to Brian and have spent much money for nothing
Since everything in the universe rotates, I think there is nothing to keep the universe its self from rotating, thus creating a sintrifical force that is pulling the universe apart. As the size of the universe increases so do the force pulling out due to the rotation. Would that explain dark energy.
If this make seance to anyone I akso have some thoughts on dark mater as well.
To think we are approaching the 10 year prediction mark and neither a dark matter nor dark energy theoretical understanding is any closer. It is all the more reason to believe that when physics finally breaks through, the theory and explanation will have profound meaning to our cosmological reality.
I can't stop to watch the videos of this channel
Actually, for a change! I really enjoyed that! great format! Great Science, I was hoping for answers sooner rather than later, but the reality of the situation is just as expected, with some awesome problems to solve.
I may have missed it, but did they say whether they considered the cumulative mass of all the stuff as we move further away from the centers of galaxies, including stellar black holes and objects too faint to show on telescopes? Did they consider the interlocked movements of moons, planets, stars, star systems, etc., and how each drags the other and is itself being dragged? No wonder they all go at pretty much the same speed when they are connected like the cars of a train ... maybe!
Also, how do gravitational ripples interact with each body independently of the mother gravity well of the galaxy's black hole?
its was really fun to watch keep going
When I realized that I was watching dancers during the 7 - 15 minutes section, and not computer graphics!
Absolute WOW !
Edit, Thank you for giving credit to MOMEX. I have seen them before and been amazed.
Why is this video classified as "unlisted"?
It says dark...they probably think it's a National Socialist Workers Party video.
