The Dark Side Of The Universe

- เผยแพร่เมื่อ 27 ก.ย. 2024
- For all we understand about the universe, 96% of what’s out there still has scientists in the dark. Astronomical observations have established that familiar matter-atoms-accounts for only 4% of the weight of the cosmos. The rest-dark matter and dark energy-is invisible to our telescopes. But what really is this dark stuff? How do we know it’s there? And what does it do? From the formation of galaxies to the farthest reaches of space, it appears that darkness rules. Without dark matter and dark energy, the universe today and in the far future would be a completely different place. We were joined by leading researchers who smash together particles, dive into underground mines, and explore the edges of the known universe in search of clues to nature’s dark side.

I may help you in french
If u r fine I can help in Hindi translation
I can translate to Klingon and Ferengi
Maybe Dark Energy and Dark Matter have something to do with information or distribution? Something like *Benford's Law* or *Zipf's Law.*
Did you know only about 4% of internet is accessible by through search engines like Google, Bing or Yahoo and remaining *96% of web contents only accessible* with special tools and software - browsers and other protocol beyond direct links or credentials. And of that 96% of the Deep Web (analog to Dark Energy??), a small percentage is the socalled Dark Web (analog to Dark Matter???).
I know, this wild idea seems almost esoterik, or seems to suggest something like simulation theory, but maybe it's something much more simpler, like *Benford's Law* or *Zipf's Law.*
Ambassadors do not do translations. That's a translator's job.
As I've said on many occasions, the World Science Festival discussions and the Royal Institute presentations keep me up well into the night. Ya gotta love science!
Op NBN
Mmmm mmmm min
You're an anonymous commenter under an anonymous username so what merit is there in stating " as I've said on many occasions...". Ridiculous.
@@bruceh92 Imbecile.
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.
😂 same here ...
Skip dance, go to Introduction - 16:30 - Show starts at- 24:58.
Ty. Im really not liking their bs halftime shows
I loved the dance but it was inappropriate to this venue and so was all the other yapping till 24:58 .
Thank you.
gosh, after listening to all the responses, you'd think these people would understand something about funding. it's called taking the bad with the good. grow up and focus your hate elsewhere...
@@rljpdx please elaborate upon the *funding* you mentioned.
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. 🙏
nice that we can see for free this on TH-cam.
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.
Brian Greene is a genius.
He has a real talent for explaining extremely difficult concepts to laypeople by having a great command of the language
Yes, he is exceptional. Humble too.
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...
Did anyone else find the 2nd host (not professor Brian) somewhat irritating?
I love this series...great for anybody interested in modern science.
I’m interested in these topics so I’m watching it
What's old science?compared to modern science
is anyone noticing how amazing those dancers are? watching them I am like wtf? really good .
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.
Great debate as usual, I just wish the moderator would stop interrupting and repeating everything they say...
He did a very good job of it though, & i was glad for it, he did his homework before the show
Brian Greene really knows how to explain clearly. But when we study very much, I feel we forget to explain thing easily.
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.
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!
GOALS!
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
Exactly what I was thinking
"Free from desire,
you realize the mystery.
Caught in desire,
you see only the manifestations.
Yet mystery and manifestations
arise from the same source.
This source is darkness.
Darkness within darkness,
the gateway to all understanding."
~ Lao Tzu
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.
! Brian Greene is a Professor of Physics and Mathematics! (Dot)
It seems fitting to me that we only really can identify a small percentage of stuff we have been around a short time
World Science Festival... best asmr videos to fall asleep to.
love the world science festivàl, im not even on your playing field, yet i manage to retain a few bits of info each time i listen. thank you.
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.
Yes but an important aspect of dark matter is that it also carries mass! It explains away the lack of mass that we observe in ordinary matter
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.
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
Nice and wonderful.... It's always a great feed from World science fest..... Thanks.
woah EPIC dance, I woke up to it thinking it's weird it's on a playlist but turns out it's still WSF. loved it
I can't wait to go and participate in this world science festival someday!
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 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?
I've felt like dark energy and dark matter can be summed up with virtual particles.
Hi Brian!
when you referred to "the dark matter as the scaffolding of the known matter"It reminded me of this revelation in Quran:
Allah is He Who raised the heavens without any pillars that you can see. (Quran 13:2)
It would be not a bad idea to use such verses just as hypothesis and see where it goes. this might have helped theoretical physicists if they knew it.
Quran also says Universe was created in six days and that humans are created out of clot of blood, should scientist check where it goes too?
Mohammad Rahmani ya seriously. shut the fuck up.
@@PiterixosI am not preaching religion here. Quran is just an ancient script. just look at it that way if you can :) Six days may mean six stages. or the human creation we now know science can now clone a copy of you just by having a stem cell of your body. so clot of blood may mean a stem cell.
@John Mitchell Those who share your attitude have a very well recorded history of a world scale collection of heinous crimes towards humanity and planet earth.
(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.
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.
I've got nothing to do with physics, but I love watching this!
25:20 - all panelists on hand
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.
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.
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!
Proverbs
(25:2) It is the glory of God to conceal a thing,but the glory of kings is to search out a matter.
... then that makes me a King...
Good discussion. Lets wait a few years ,and maybe someone can come up with a different approach to proving these theories.
Hugo Malave yes it seems like we are not even aware of the right tools to properly observe whatever Dark matter/energy are.
Excited to hear about the findings of the JWST in regards to dark matter and dark energy
I'd avoid mentioning entertainers as the JImmy Savile / similar investigations continue.
or politically connected people and royals too
"Don't Go To The DARK SIDE, Luke"
That dance must've been at least an hour long
totally
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.
the dark side of the universe is ruled by the sith..
Amen.
It’s a trap!
Love you Brian Green Sir .and WSF....Lot of knowledge with great fun and great people..
its was really fun to watch keep going
Some people sleep to white noise...I sleep to world science festival.
When I hear them disrespecting Glenn Beck and his ilk,.. I know I'm on the right team,...
🤘🤓🤘
Im surprised michio kaku does not feature in the WSF
Dang, just realized this is 7 years old. So, what was thought about dark matter and energy in 2015-6?
Holy crap, ,55 minutes in and not one of the guys had said one word.
I know, and as we are all aware that women should be doing the Ironing wearing only see-through underwear we can deduce that dark matter is a feminist plot to undermine Jordan Peterson! Dark energy is the fitness level needed for these women to crawl through the tunnel connecting the Kitchen to the bedroom, the only two parts of a house that women are allowed inside. Think about it for a while and, trust me, it will all start to make sense!
@@stevebrindle1724 ...lmfao....typical women..can't shut up,always yapping....dya know they spent ALL night on the phone to one another chatting tactics for this 'debate'....they eventually came to the theory the universe needs some cilit bang,rubbing together in the bathtub handwash prep and boil washed to get all the dark matter out!
I joke of course,the ladies in my life rock!
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"
I figured out everything
Im so glad we can all have free ideas and not be killed for free thoughts.
Brian Green such a good host
Hockenberry tries real hard to be funny. Fails miserably.
Your comments fail miserably. STFU
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.
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
instead of having this an hour long, just have vsauce do a video about it lol
I love watching science stuff, makes me almost regret dropping out of high school. With that said, I do believe that both of these theories are true. We have Dark matter in the form of Dark stars and we have dark energy, which is the positive pole of the Aether. I believe the Universe is simple, I believe that the answer to all these questions lies in meditation, in tapping into the Higher consciousness, the Higher Power. I'm grateful that there are amazing dedicated people like the guests we've seen here, making all the mathematical calculations. It is a great gift to mankind and I'm sure they love doing it and they have computers to do all the impossible math, so it doesn't have to take a hundred years, it just takes intuition. We need proof that all these theories are the fundamental objective truth, but we will unfortunately never find it without first finding God and no one likes a movie with spoilers in the intermission, so no one likes an experience without mistery and the thrill of unveiling the truth behind the mistery. But there are people that know how everything works, we are these people, we just can't remember because it was your choice before embarking on this misterious adventure we call life. I know that Gurus are going out of fashion, God is going out of fashion, but the Force, well that is always in fashion, it resonates with our Psyche. So the answer is actually quite simple, we know how everything works, but we need proof. We know that gravity has two poles, let's call it planks, gravity is the negative pole and anti gravity is the positive , the first attracts and the latter repulses. We categorize this into 4 Forces, but gravity has many more, it's adaptable and different circumstances will make it appear different. For example,if two particles are entangled over a period of time and in close proximity, they bond, they become part of each other and become atoms, electrons strengthen these bonds, but at some point the physics break down, because atoms maintain their properties without adding anything more to it's "relationship", if an atom of oxygen kept adding protons to it's atomic structure, it would become something else, but we still have oxygen atoms, and this is where the hand of God manifests itself, this balance between creation and destruction, its right in our faces, but we always dismiss it as being just random chance, but it's BOTH. The Universe is simple, it is random chance and balance, order and chaos, divine in all it's process. Many Gurus state that we have had 84 Big Bangs before this one and that the past repeated itself , but the will of the Higher consciousness can change the future by deciding differently in the present. I had to explain this theory, before I explain how the Universe works. Which is basically what our ego refuses to see, as if it's actually our will to remain in the dark, as to keep the mystery going. There is only ONE energy, one Force that permeates everything, both positive and negative, repulsive and attractive, it just has different ways or different strengths. String theory is correct , super symmetry is correct, multiverse is correct, time is linear, relative to gravity, but still moving forward, it would take the will of God to reverse expansionism, in order to reverse time, but it's possible. There are gravity whirlpools, that are powered by the interaction of the these planks, which are Space-time as they interact while being pushed by the expansion of the Universe, they later become wormholes and most of the time Black holes. These are just gravity pools of the same polarity, that became so full of mass that they stabilize and "eat" up all mass, but as opposed to magnets, same polarity in gravity doesn't repel it's "planks", it just groes stronger and then affect space, because the are space that filled up with matter and can be used as wormholes, unless they are made of dark energy which is still gravity, but repulsive and therefore opposite poles will be rejected (i.e the different speeds at which stellar bodies gravitate in orbit of stars), Hawking radiation is basically just particles that are made of Dark energy that either enter the Black hole, become anti-matter and get "spat out" or become anti-matter while going near it and never get in and we read the data as Hawking radiation. So we have gravity, attractive, anti-gravity, repulsive (to us, in our universe), anti-gravity is dark energy. We have matter and anti-matter of both "poles", we have atoms of anti-matter where its bonds are comprised of Dark energy (anti-gravity), we have atoms where its bonds are comprised of gravity. If anti-matter touches matter , it becomes neutral gravity and then becomes gravity or anti-gravity, depending on the pole with higher energy, but it can sometimes become the one with less energy, if they're of close amounts of energy. Nothing is still, space isn't still, except in the walls of a wormhole and in the event horizon of black holes. A space ship with a gravity generator can safely enter a Black hole if it's propelled fast enough, it can move instantaneously through space , by compressing space in front and expanding it behind, this is how aliens travel. To generate gravity we need anti-gravity, we can make it with our current technology, its basically an anti-gravity generator powered by anti-matter and alien ships are self powered, they use the energy of stars to create anti-matter and then use nuclear fission on the anti-matter reactor to make anti-gravity and affect space, they can also make regular gravity. If you use a Higgs boson particle it speeds up the process of making atoms. They have forges that literally make any element, there are way more than 115. All matter is just energy, you can create it by applying electro-magnetism, basically vibration, but here's the thing, the spark of creation is actually gravity and anti-gravity interacting. For example, you have a hypothetical micro particle, the plank, lets call it that and you have anti-planks. These two planks are space-time, it is their interaction that creates frequency in the fabric of space-time and generates "up's" and "down's, this frequency is TIME, without it, our physical Universe does NOT exist. This interaction is what creates everything really, it exists everywhere, in everything, it permeates the universe, the same way water permeates a full container, there is no empty space, vacuum is not empty, its just devoid of bigger particles. Also, there is only 3 dimensions, you have other "dimensions" , but they're still bound to our spatial dimension and are not perceivable, like ghosts. We have Universes where anti-matter and anti-gravity are what makes up life, but those will never collide with ours, because Universes repel. This is just what all the people that develop their intuition discover, such as gurus, yogis, etc, or maybe its just imagination ;) And we very rarely see them on tv, except Sadhguru, he is genuine, he appears on tv to help and fund projects that will make the world better. If we must teach something to our future generations, it is this, AWAKE, free yourself. Unfortunately my time is up, I hope this serves someone. Watch Sadhguru, enlighten yourself.Thank you for reading. Much love from Portugal. We are ONE. Namaste.
there 17 sub atomic particles in the standard model, 6 quarks 6 leptons 5 bosons, though alltogether there are over 200 known particles, and in the observable universe there are 10`83. dont ask me to write that out as a actual figure, id be here all day lol
have you seen joseph newmans electromagnetic engine. free energy forever, been known for decades but the mighty conglomorates wont have none of it, too much invested in fosil fuels, the fools will be the end of us for mear profit, but in there minds theyll just build a big space ship and fly away with all there money. lol love to see the aliens when these greedy sobs try buying materials with ben franklin notes hohoho. zap goes the alien space gun lol
Interesting theorems , I believe we will never figure it out because we are not meant to , our observation changes the “ physical” world we are in note the two slit experiment where photons act different under observation , it’s more likely we are in a simulation
Reason the universe is expanding at greater than the speed of light is the fact that the gravity of other several universes ( multıverse ) is so strong that it our universe is expanding So fast. This might be the reason , so is our universe is also causing other universes expand . The point the other universe crash to each other ,we will have a new big bang
Who the hell hires this incredibly annoying moderator year after year. He's wasting the potential for discussion among all these brilliant minds on stage with his stupid jokes and constant interruptions. Ruined the whole thing! So frustrating!
Someone who buys cocaine off of him...sniff.
Used to like him in the first couple vids but now its annoying
Mitja Irsic no one he hires himself, he’s chairman of WSF
gravity bends light or gravity bends space resulting in bend of lights path?
first 20min are waste of time
lol
thanks
no it's not
The dancing green arms and legs were fun to watch.
Calling what Brian Green has to say a waste of time doesn't put you in good llight...
listen to Piterixos' sound judgement
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...
They introduced gender quotas in science festivals?
+kaczan3 They always did, mostly negatively. Look at the photo from the Solvey conference 1927, just one woman. They say a woman has to be twice as good, and Marie Curie sitting there with her two Nobel Prizes. Search science, and look at Jocylen Bell, and her lack of Nobel Prize, Emmy Nother, and how fundamental, central her position is in modern science.
in Britain, Hertha Marks Ayrton (mathematician, engineer), Margaret Huggins (astronomer), Beatrix Potter (mycologist);
in France, Dorothea Klumpke-Roberts (American-born astronomer);
in Germany, Amalie Dietrich (naturalist), Agnes Pockels (physicist);
in Russia, Sofia Kovalevskaya (mathematician).
Lise Meitner
You have to dig to find women, because they're not even expected to address science, but they are there, and significant.
Brian Greene is THE MAN!!
Rather than calling it dark matter or dark energy would it not be more accurate to call it dark knowledge.
We Live in the Small, Our human Body is the universe, we all live in Someone!
This is a really really good science festival😁👏👏👌 For me one of the best ones👌👌
Was this gender divide on purpose or accidental?
Yeah ... what's up with that?
fistfull ofdollars Maybe they wanted to give comical a feeling of "boy's vs girls" or it was accidental.
Could be both.
lloydgush You could be right!
Yeah, and why did they put the disabled guy by himself???
Niskinatorn Because he was the host.
This panel should have had those physicists who disagree, the ‘fringe physicists’ one of these ladies joked even though she conceded they were mainstream and highly respected doctors. There should’ve been someone to argue that ‘dark matter’ is the new ‘cosmological constant’ or even an ‘ether’, I.e. just something created to make the numbers fit into the equations.
Informative, but I'm still highly skeptical of both dark matter and dark energy.
Jo Reven dark matter and energy are just catch all terms for matter and energy that we can't explain yet. As mentioned in another vid, neutrinos which have been proven, qualify as dark matter, there just isn't enough of them to make up all of the "dark matter".
Michael Durkin What other video are you talking about?
Jo Reven Thank you 😊
yup,me to buddy.
I always picture the universe like a firework. It explodes fast bright at first and flares up as it expands and dies out with time occasionally there are sub explosions that spread more bursts of light but are just as quick to fade as all the sparks move away from each other. and cool till all they are is embers then nothing but ash. That is what i think our big bang was really and this would work with the big freeze theory where all the stars die out fade and turn to cinders and ash.
The other option is that the big bang is still going on in a way. The big bang is Einsteins white hole and we are riding on a wave or a pulse from this white hole. We are speeding up because a newer wave is catching up to us and transferring energy from it to us as the wave behind it is transferring energy to it etc. This would explain dark energy we cant see it because its like a pressure pushing on our wave / bubble from the bubble behind us.. Just think of a drop of water hitting a body of water. The ripples propagate and radiate outward moving faster as they expand and the wave behind it pushes it. Water however meets friction by pushing on other matter so slows down eventually and the source is not continuous. If it was however it could keep expanding as long as there was water.
Now imagine a bubble where we live expanding and the bubble inside our bubble pushing out on us the bubble inside is primarily made of antimatter and out bubble is made of matter. Where their antimatter gathers is where we have little or no matter and helps to cause our matter to gather. This could help to explain dark matter and dark energy both and because we can barely grasp the concept of spacetime and dimensions at this point this could be a very solid reality but we cant see it or prove it based on our current technologies.
The way this commentator finesses his stage commentary ability is bar none top A grade 😅... Bravo
How about this? Galaxies radiate spacetime in the form of gravitational waves, which is what is adding more space between the galaxies?
That dance was absolutely beautiful!
Good presentation. Much to decipher.
In the whole discussion of Dark Energy and observing super novas the one thing I don't see anything about is Einstein's theory involving time dialation approaching infinite as the seperation approaches the speed of light. This would make the most distant objects appear closer than the nearest compared to the "real" distantce they would appear if the red shift was the only measurement. This might not eliminate Dark Energy but might make the msth agree with the observations. This should make super novas most distant appear to take much longer than closer ones do. I have not seen any information on this.
Loving this episode tremendously!
Why is this video classified as "unlisted"?
It says dark...they probably think it's a National Socialist Workers Party video.
I have just one Question, Does black holes feed on dark matter/energy?
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.
I believe anyone should be able to ask any question anywhere...that is the nature of true science.. and its a matter of choice on the participant most definetly what picture is used
It's all about finding the truth. 2 thumbs up
Fantastic Panel again.... Yeah could blackholes contribute or perhaps even just be responsible for the expansion of the universe?
They seem to interact on the planck level with the fabric of spacetime and as the universe grows larger, the expansion would increase.
Somehow there's also a hint that spacetime itself is just very flexible, perhaps even has a shape-memory kind of property because any coordinates a blackhole passed trough, might just be regular space again after.
I am convinced of the existence of both dark matter and dark energy, although no detection of dark matter yet.-!!!
I'd avoid mentioning entertainers as the JImmy Savile / similar investigations continue.
I have a question. If you consider all the photons of whatever wavelength ever released by the energy of the big bang, and you consider the energy density of that sea of photons spreading throughout the universe over time, what is the effect on the mass, and the space, caused by that energy density. We consider each cubic meter of space to be empty, apart from an atom or two per unit volume, but we need to count the sum of the total energy transiting the space from every angle before we can truly say the space has been weighed and counted. Maybe there is no dark matter, maybe its just the energy density between the stuff we can see. Sadly this one is a little beyond my math level right now. Someone tell me what the figure might be? If you remember from any point in space you can see total sum of light arriving from all directions at that instant in time, iff you could open your eye to all the frequencies across all the observable universe. That has to be a big number in its own right.
you know if you would advertise the life stream i would actually watch it. but i have no idea when the next life stream will happen and how i can watch 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?
+Apoc According to Albert.
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
I have had my 2013 ram1500 3.6l for about 4 years now. It only had 89k miles at purchase. Other than some minor electrical problems, including NY ac quitting on me 2 yes ago, and my electronic expensive as hell 3k$!!! Power Steering pump...smfh....other than that and the motor in my window going out and more oil leaks than I can count. Sparks plugs going bad at yr 1, changing out the fuel pump, starter, battery and the alternator, 2 belts. 1 tensioner pulley, countless oil changes, oil pan replacement, 2 battery terminal replacements, blower motor and resister replacements, replaced my gear shifter know 1 yr ago because it broke down in my drive way no warnings at all just quit 1morning when I was otw to work.... both headlights also went out along with the left back blinker light bulb and front right blinker bulb, I also had to replace the air filter and the fuel I
Injectors... I'm sure I'm missing a few but after all that in 4 years, I'd say I'm about done with dodge.... it had 89k miles, it now has little over 250 thousand miles. U tell me?? Good truck or pos? I'm tired of being broke down and Broke!!
Ratio of dark matter and dark energy is like a ratio of Hegel's participating opposites, that unites to produce a universe out of a possible many, that has the right parameters to make life and consciousness, says God ,alias Hegel.
great as always! it was fun to watch even for a non-scientist like myself
Hi there ... i have one doubt about this dark energy description that in one sense it is the stretching of space in between each and every galaxies so that we can see all the galaxies are moving away in an ever ending acceleration.
So My question is how we quantified the share into 73% about this increasing influence caused by dark enegy ...!?
Your detector is flowed it needs to be on a gyroscopic platform and pointed to the center of our galaxy and at least % feet of lead (bismuth or antimony) alloy, that will only detect dark energy. Dark matter can only be seen as SIGMA (the momentum and mass of it)
alright, how about this: the universe's density is inversely proportional to it's size. big bang happens. as matter reaches the edge of the universe,it is effectively tending towards infinity in size. having near infinite size, it's density(mass) tends towards zero. having a mass of zero positive(expressed as information a.k.a time) it can redistribute itself evenly(ish) across the cosmos, instantaneously, it's already near infinite in size. so the matter gets converted to space-time. that redistribution causes the expansion on the universe (distance over time). that inflation is how matter can reach the edge of the universe. so there'll be a heat death, and just short of infinite amount of space-time. since the universe is self-contained(educated guess) it's accelerating because as the volume of time-space builds up, the ratio of matter drops.
