This was a great one. I really appreciate the 1 on 1 conversations. They are always deeper, more historical, more coherent, and more educational in my opinion, than the big panels are.
Agreed. BG obviously knows his stuff. You could tell the guest was impressed with Dr. Greenes basic knowledge of the subject and his preparation for the interview. Great questions without hesitation.
Im a registered nurse, never took a physics class in my life, but I love these videos and have learned so much from them. I also have a huge crush on Brian Greene, as I think, judging from the comments, many others do, too! 😊Thank you for such interesting information! Cheers from PA, USA
We are so very lucky to learn from some of the worlds foremost physicists and scientists like Brian , Sean Carrol and many more. As a total layman I find these talks totally fascinating. You can see what you can about social media, but this is one of the positive results of it.
I watched an interview with Nobelaureate David Gross. The interviewer asked Gross "what's everything made of?" and handed him the microphone. She settled in for a long answer. His response "two quarks and an electron" and he handed the mic back. This interview had a similar impact on me. James Peebles has a no-nonsense, cut-to-the-heart approach that is very insightful and refreshing. Bravo Brian Greene!
Combining enlightening Information with subtle humour, great guests and conveying the content in a understandable way makes this a special channel to me (and so many !) 👏 Thanks a lot from Germany for promoting science in times when facts are so often disregarded 👍
This is one of the best and most inspiring episodes I have seen. Dr. Peebles really enjoys the ideas of not being certain, hence creating an atmosphere of discovery, as well as inspiring new ways of thinking about the universe.
This was a great conversation as always. Loved the way Prof. Peebles discussed his ideas, they really gotta have people like him and Prof. Greene in classrooms.
Amazing Talk. James Peebles is fantastic! So clear and simple in the way he speaks and so wiling to say there are things he can't even guess at. One your best guests, Brian.
This was flawless. SO interesting. Thank you for putting it together and thank you both for your knowledge that we can gain just a glimpse of, but how satisfying! I love that it ended with questions. I was surprised! I thought we knew why many galaxies form spiral arms... Now my curiosity is piqued.
Amazing interview with a true champion of modern cosmology. His historical perspective on the development of the CMB and the Std model is priceless. At the end, thanks to Brian's cunning open question, several hard issues were posed for future generations. Peebles is in favor of keeping the fundamentals and focuses on correcting the details. Fortunately, so many of the details need ammendment that there's plenty of room to review the foundations as well.
This reminds me of years ago on Christmas morning, when the kids were trying to work out how Santa got all those toys down the chimney and placed them around the room and them asking how Santa knew just which presents each of them would like. If I'd have told them they just appeared from nothing, they would never have believed me.
Brian you really are doing great work with these questions. And very good answers from James as well! Dark matter and Dark energy are "patches". Well said!
The universe doesn't make men like this anymore. The pressure applied by corporations on staff has ended his kind. Very enjoyable discussion with a beautiful human.
Thanks great discussion. As for why there is nothing at all, it is clear nothing is unstable, it tends to decay to something. That is self evidently true.
20:40 Gamow's "intuition" is actually the realization of the academic knowledge he received from his teacher. P.S. Almost all peoples have myths about the beginning of the universe, but the first scientist who spoke about the "creation of the world" (literally) is Alexander Friedmann, who, with his solution of Einstein's equations, gave a scientific explanation to this phenomenon. Moreover, without any astronomical observations, he was able in his article (1922) to theoretically estimate the age of the Universe: about 10 billion years. (!) Friedmann's student Gamov also calculated (1948) this value as (1-10)K without astronomical data, that is, before the detection of the relic radiation. (!) P.P.S. "All thoughts that have huge consequences are always simple."(Leo Tolstoy).

I'm pretty certain that nearly a third of the time I've been watching has been for ads. RUclips is relentless and it makes following the discussions very difficult.
49:39 "A purely algebraic theory is required to describe reality." (Einstein, January, 1955). Maybe GR was QG… “The geometry of space in general relativity theory turned out to be another field, therefore the geometry of space in GR is almost the same as the gravitational field.” (Smolin). However apparently, the gravitational field is space-time in the Planck system: F(G)/F(e)=Gm(pl)^2/e^2=1/α, that is, gravity~strong interaction*. This assumption follows from the Schwarzschild solution: the gravitational radius (or Schwarzschild radius) is a characteristic radius defined for any physical body with mass: r(G)=2GM/c^2 Consequently: 2E(0)/r(G)=F(pl)=c^4/G=ε(pl)/r(pl): with indicating the mutual quantization of the mass (energy) and space-time: m(0)//m(pl)=r(G)/2r(pl)=n,where n-total number of quanta of the system; the tension vector flux: n=[(1/4π)(Gћc)^-½]gS ( const for all orbits of the system: n=0,1,2,3....). Moreover, the parameter r(0)=r(G)-r(pl)=(2n-1)r(pl), defining the interval of the formation of the system, at n=0, when r=r(G)=0 (for example, the state of the "universe" before the Big Bang) turns out to be a quite definite quantity: r(0)=-r(pl). In the area [(-rpl) - 0 - (+rpl)] there is an implementation of external forces, "distance": (-rpl)+(+rpl)=0 (≠2rpl). On the Kruskal diagram of the hyperbole r=0 corresponds to the true Schwarzschild feature, the features V and VI are not even covered by the global (R, T)- space-time and correspond to the "absolute" vacuum; then the singular areas above and below the hyperbolas r=0 can be formally treated as the energy source (external forces). That is, the frightening "true singularity" is actually a superconducting heterotrophic "window" between the proto-universe (the source) and physical bodies**. P.S. As a fundamental theory, GR has the ability with just one parameter: r(G)/r=k to predict, explain new physical effects, and amend already known ones. Photon frequency shift in gravitational field Δw/w(0)=k; the angle of deflection of a photon from a rectilinear propagation path =2k, the Newtonian orbit of the planet shifts forward in its plane: during one revolution, a certain point of the orbit is shifted by an angle =3πk, for a circular orbit (eccentricity е=0); in the case of an elliptical orbit - for example, for perihelion displacement, the last expression must be divided by (1-e^2). ------------------- *) - GR predicts a new physical effect: w/w(pl)=k; expression for gravitational radiation from a test body. This is amenable to physical examination in laboratory conditions at present. **) - From this, generally, from Einstein's equations, where the constant c^4/G=F(pl), one can obtain a quantum expression (as vibration field) for the gravitational potential: ф(G)=(-1/2)[Għ/с]^½ (w)=-[h/4πm(pl)]w. Final formula:ф(G)=-[w/w(pl)]c^2/2, where ф(G) - is Newtonian gravitational potential, r(n')=nλ/π=(n+n')2r(pl)l , the corresponding orbital radius, w - the frequency of the quanta of the gravitational field (space-time); - obviously, the quanta of the field are themselves quantized: λ=(1+n'/n)λ(pl) = 2πc/w, where n'/n - system gravity unpacking ratio, n'- the orbit number (n'=0,1,2,3…). Obviously, on the horizon [r=r(rG), n'=0] the "door" is closed, however, the quanta [λ=λ(pl)] can go out singly through the "keyhole" and form the first and all subsequent orbits (n'=1,2, 3 ...) during the time t(0)=r/c=2nт, where т=1/w, т=((1+n'/n)т(pl), spending part of their energy on it each time. And it is this mechanism that provides the step-by-step formation of the gravitational field ( expansion of the space-time): of course, the quanta coming through the "window" are also rhythmically restored. The phase velocity of evolution v' = r(pl)w: m(0)=(c/G)rv', where v'=v^2/c. The angular momentum: L(p)=|pr|=n^2ћ [const for all orbits of the system; at n=1: L(p)=ћ] and moment of power: M(F)=dL(p)/dt(0)=nћw/2=-E(G),where t(0)=r/c. Entropy (here: a measure of diversity/variety, not ugliness/disorder) of the system: S=πε(pl)r(t)=(n+n')k, where k is the Boltzmann constant. Obviously, with fundamental irreversibility, information is preserved (+ evolves): n=const for all orbits of the system. Accordingly, m=m(pl)/(1+n'/n), where m=ħw/c^2, is the quantum of the full mass: M=n'm [
(at 43:52) Tycho Brahe was not 2000 years ago. Look at Brian being polite when Jim blotches that one. It was a good talk. Jim is such a significant figure in the field. Priceless stuff. So is the heads up that there are live shows this month. My intuition tells me G.R. is flawed. I know there's multiple experiments pointing to both Dark Matter and Dark Energy but are any of them independent of General Relativity. If not why isn't this being talked about? I admire Einstein's genius too but gravity is a tough concept. Unless you have actually worked on Gravitational theory it might be hard to grasp how seriously elusive it is. Thanks again Brian
Are we able to measure the rate of collapse of star-forming nebulae, and if so, is this rate of collapse consistent with the matter we can see, or is there also unaccounted dark matter coming into play here, as with that in galaxies?
May I suggest MOND due to the fractilization of space itself by black holes, and also recursional unconscious, creational dynamics... Thank you for posting, I appreciate your effort in making this video. You are cleaning peoples minds :-) Bodhisattva.
Good question. What we left out is that we are saying blackholes instead of saying bright spots because everything we see in the space is same color with uncountable of stars including the sun. Ok. Let put into scale which is bigger the unoccupied space or sum up of the stars occupied space. It the like the question of the paper with the dot and you ask a person what do you see. They respond a dot without mentioning the rest of the paper, you holding and whole background behind you. This was a great discussion. I will watch it again for sure. Thank so much our seniors.
What the heck do you mean everything is the same color? Black holes are black in a figurative sense. It is the accretion discs around black holes that are luminous.
The real question is why there are massive clumps of matter to form Galaxies but with such great distance between, as the material concentrates it increases the distance and thus vacuum energy between it and another galaxy which helps to explain the growing distances but why there is distance in the First place seems puzzling.
After the slit experiment both particles behave differently.. how does relativity apply here.. In Quantum I think it's a difference.. I may be wrong .. but just wondering
On stage a man link of Physics and Cosmology , CMB to dark matter loop of non baryonic mass. Another new link of Super symmetry and repulsive gravity. This discussion is versatile for all levels. Science with pictures.
No one in the comment section expressed amazement how and why light illuminated the dark universe. So, with cyclic universe the same illumination goes on from cycle to cycle. What triggered this? The answer lies in the fact that infinite complexity becomes deterministic, this is where divine design finds water, as life, consciousness, soul and faith etc., are all metaphysical fundamentals.
As a guess, I think the black holes and surrounding stars are forming concurrently so questions of what came first are not the key to it. I am guessing due to the jets that eminate from the developing Black hole that material cannot surround the Black hole in a ball shape and thus forces the stars to spiral in a disc plane, the energies involved in the jets wouldn't allow for stars to surround the Black hole in a ball like fashion, hence the disc like fashion. Just a guess.
i think i have physics intuition but not passion , so im just not sure how i best learn. maybe non baryonic matter just needs to be closer together to exhibit more energy, and baryonic gravitation pulled it apart enough (by forces and gravity) to be cold now even if it wasn't cold in the past..? maybe when there's less baryonic matter pulling it apart, whatever dark energy "is" simply can't stay hot enough for our instruments to detect..? that's why some ppl believe the dark stuff has physical properties beyond just "leftovers from the big bang", while others think it could interact vary differently (with itself) depending on some unification (of forces) in the past that kept it together but has now spread out and formed massive webs of baryonic matter amidst a cold foam?
The disc nature could also be related to massive magnetic fields being created by the Black hole also limiting the position of surrounding stars. Again just guesses. If you think about magnetic field patterns there are loops to the "north" and "south" with the lines eminating more to the east and west which could help to constrain stars into the planes without the loops but more linear features on the "East" "West" planes.
"You need to discover what we left out of this theory" All of the people who watched this great interview is going to suffer anxiety attacks night after night
very confused about this CMB. A form of light emitted at the beginning of the universe, and stops shortly thereafter... if the big bang is true, and was a singularity, then the CMB light was emitted eons ago from that singular point, and zoomed away from the singularity at the speed of light, then matter appeared. Now, I know when I turn off my flashlight, the beam doesn't just vanish, it's just not being emitted anymore - the beam continues basically forever. just like the light that created the CMB...yet, somehow...you can detect it? ChatGPT tells me it "permeates" space, but if that's true....then...the CMB can't be light...for light doesn't just stop in its tracks. so how in the devil are you all able to detect it well after it's been emitted? is the CMB truly a form of light?? input - more input! :)
The moment a particle is a wave; it has to be a conscious wave! Gravity is the conscious attraction among waves to create the illusion of particles, and our experience-able Universe. Max Planck states: "Consciousness is fundamental and matter is derived from Consciousness". Life is the Infinite Consciousness, experiencing the Infinite Possibilities, Infinitely. We are "It", experiencing our infinite possibilities in our finite moment. Our job is to make it interesting!
I just learned that nearly 1% of the static you find in old televisions is from the cosmic microwave background radiation. It used to be an irritant. Now, I am constantly in awe of it as I realize its connection with the Big Bang. It's no longer some random signal from the void. It's home calling out to us.
7:54 .. You immediately won my heart saying you are theorist. I love that. I was trained in lateral thinking. Apparently I'm an existential ethic. I write about our makings. Truth is not just stranger than fiction. It's a lot more funnier, and sometimes more terrifying. There are things that I can't write. Like, god may be 'loneliness is hungry'. It's like we are in a mouth. If the universe are the two things, E=mc² & proximity + instantaneity (abiogenesis), and we be tendrils of sniff searching for safe crevices, &, ..well.. maybe come and read my latest work. E = mc² is tongue. Proximity and instantaniety may be mouth. Black holes are teeth. The sun is nasal cavity. Behind sniff, & in front of it, because sniff was all we had before time spun When black holes shattered self-healing reality. To sniff where safe crevice in space before E=MC² . That we smelt, was a testament to that we would smell. Basically, smell and taste are on opposite sides of one another, and betwixt them is the ticktweentime gap between you and you, which also happens to be also the inner-sharp-shard-star path of ever altering predetermined fate. Absolutely I am talking about smell in regards to marking territory.. .. Let's go Let's go, I can't wait to show you what I've got. Take it. It's heavy. I write about the relocating earth. We move. I think it's about time scientists stop expecting free writers to pay for our writers tech. I absolutely think you're going to kill us. You don't take care of your writers . We're in big trouble. I'm beginning to think, no matter what you do, I will never look at you the same way again if you don't help us. At least, we need better Google microphone. We've got something that feels to me like a gimmick from some show bag . Sometimes, I die inside. You are so neglectful.
It is simple. Prof Neil Turok has a theory that solves numerous issues including but not only Dark Matter. It is the Universe/Antiunivers pair. Prof Turoks theory makes testable predictions.
Cosmic Microwave background cannot be presently Standing in one piece against an Expanding Universe. Even more qualified is this Universal Law, the Stronger Energy Flow overrides the Weaker Energy Flow at all times, which certainly would've destroy that Cosmetic Microwave background.

That is, the frightening "true singularity" is actually a superconducting heterotrophic "window" between the proto-universe (the source) and physical bodies**.
P.S.
As a fundamental theory, GR has the ability with just one parameter: r(G)/r=k to predict, explain new physical effects, and amend already known ones.
Photon frequency shift in gravitational field Δw/w(0)=k; the angle of deflection of a photon from a rectilinear propagation path =2k, the Newtonian orbit of the planet shifts forward in its plane: during one revolution, a certain point of the orbit is shifted by an angle =3πk, for a circular orbit (eccentricity е=0); in the case of an elliptical orbit - for example, for perihelion displacement, the last expression must be divided by (1-e^2).
-------------------
*) - GR predicts a new physical effect: w/w(pl)=k; expression for gravitational radiation from a test body.
This is amenable to physical examination in laboratory conditions at present.
**) - From this, generally, from Einstein's equations, where the constant c^4/G=F(pl), one can obtain a quantum expression (as vibration field) for the gravitational potential: ф(G)=(-1/2)[Għ/с]^½ (w)=-[h/4πm(pl)]w.
Final formula:ф(G)=-[w/w(pl)]c^2/2, where ф(G) - is Newtonian gravitational potential, r(n')=nλ/π=(n+n')2r(pl)l , the corresponding orbital radius, w - the frequency of the quanta of the gravitational field (space-time); - obviously, the quanta of the field are themselves quantized: λ=(1+n'/n)λ(pl) = 2πc/w, where n'/n - system gravity unpacking ratio, n'- the orbit number (n'=0,1,2,3…).
Obviously, on the horizon [r=r(rG), n'=0] the "door" is closed, however, the quanta [λ=λ(pl)] can go out singly through the "keyhole" and form the first and all subsequent orbits (n'=1,2, 3 ...) during the time t(0)=r/c=2nт, where т=1/w, т=((1+n'/n)т(pl), spending part of their energy on it each time. And it is this mechanism that provides the step-by-step formation of the gravitational field ( expansion of the space-time): of course, the quanta coming through the "window" are also rhythmically restored.
The phase velocity of evolution v' = r(pl)w: m(0)=(c/G)rv', where v'=v^2/c.
The angular momentum: L(p)=|pr|=n^2ћ [const for all orbits of the system; at n=1: L(p)=ћ] and moment of power: M(F)=dL(p)/dt(0)=nћw/2=-E(G),where t(0)=r/c.
Entropy (here: a measure of diversity/variety, not ugliness/disorder) of the system: S=πε(pl)r(t)=(n+n')k, where k is the Boltzmann constant. Obviously, with fundamental irreversibility, information is preserved (+ evolves): n=const for all orbits of the system.
Accordingly, m=m(pl)/(1+n'/n), where m=ħw/c^2, is the quantum of the full mass: M=n'm [
(at 43:52) Tycho Brahe was not 2000 years ago. Look at Brian being polite when Jim blotches that one. It was a good talk. Jim is such a significant figure in the field. Priceless stuff. So is the heads up that there are live shows this month. My intuition tells me G.R. is flawed. I know there's multiple experiments pointing to both Dark Matter and Dark Energy but are any of them independent of General Relativity. If not why isn't this being talked about? I admire Einstein's genius too but gravity is a tough concept. Unless you have actually worked on Gravitational theory it might be hard to grasp how seriously elusive it is. Thanks again Brian
WONDERFUL!!!!
I admire the great maps of the standard galaxy ..that provide us to study further...
Gosto muito de ver cada vídeo.
Porém não falo inglês.
E já existem vídeos com tradução pela IA.
Poderiam fazer isso para o português?
Thanks for the wake-up call. We are specials but not so special now ,aren't we 😂😂
i love these gentlemen
"Maybe its inevitable that such brilliant intuition must go along with a certain dislike of authority"
:)
Wonderful discussion. Thank you
Are we able to measure the rate of collapse of star-forming nebulae, and if so, is this rate of collapse consistent with the matter we can see, or is there also unaccounted dark matter coming into play here, as with that in galaxies?
May I suggest MOND due to the fractilization of space itself by black holes, and also recursional unconscious, creational dynamics...
Thank you for posting, I appreciate your effort in making this video. You are cleaning peoples minds :-) Bodhisattva.
Excellent
Oh you young LEARN LEARN FROM THIS GENIOUS ❤
Good question. What we left out is that we are saying blackholes instead of saying bright spots because everything we see in the space is same color with uncountable of stars including the sun. Ok. Let put into scale which is bigger the unoccupied space or sum up of the stars occupied space. It the like the question of the paper with the dot and you ask a person what do you see. They respond a dot without mentioning the rest of the paper, you holding and whole background behind you. This was a great discussion. I will watch it again for sure. Thank so much our seniors.
What the heck do you mean everything is the same color? Black holes are black in a figurative sense. It is the accretion discs around black holes that are luminous.
@@philipm3173 Are we in one of them or they are just out there?
does the background radiation temperature ,2.3k, drop over time? Or will it retain its value
Great!!!!
The real question is why there are massive clumps of matter to form Galaxies but with such great distance between, as the material concentrates it increases the distance and thus vacuum energy between it and another galaxy which helps to explain the growing distances but why there is distance in the First place seems puzzling.
After the slit experiment both particles behave differently.. how does relativity apply here.. In Quantum I think it's a difference.. I may be wrong .. but just wondering
On stage a man link of Physics and Cosmology , CMB to dark matter loop of non baryonic mass. Another new link of Super symmetry and repulsive gravity.
This discussion is versatile for all levels.
Science with pictures.
No one in the comment section expressed amazement how and why light illuminated the dark universe. So, with cyclic universe the same illumination goes on from cycle to cycle. What triggered this? The answer lies in the fact that infinite complexity becomes deterministic, this is where divine design finds water, as life, consciousness, soul and faith etc., are all metaphysical fundamentals.
As a guess, I think the black holes and surrounding stars are forming concurrently so questions of what came first are not the key to it. I am guessing due to the jets that eminate from the developing Black hole that material cannot surround the Black hole in a ball shape and thus forces the stars to spiral in a disc plane, the energies involved in the jets wouldn't allow for stars to surround the Black hole in a ball like fashion, hence the disc like fashion. Just a guess.
The best.
i think i have physics intuition but not passion , so im just not sure how i best learn.
maybe non baryonic matter just needs to be closer together to exhibit more energy, and baryonic gravitation pulled it apart enough (by forces and gravity) to be cold now even if it wasn't cold in the past..?
maybe when there's less baryonic matter pulling it apart, whatever dark energy "is" simply can't stay hot enough for our instruments to detect..?
that's why some ppl believe the dark stuff has physical properties beyond just "leftovers from the big bang", while others think it could interact vary differently (with itself) depending on some unification (of forces) in the past that kept it together but has now spread out and formed massive webs of baryonic matter amidst a cold foam?
The disc nature could also be related to massive magnetic fields being created by the Black hole also limiting the position of surrounding stars. Again just guesses. If you think about magnetic field patterns there are loops to the "north" and "south" with the lines eminating more to the east and west which could help to constrain stars into the planes without the loops but more linear features on the "East" "West" planes.
The ending felt like he's gonna take that 💩 to the grave cause he ain't helping no one steal that nobel 😂 I wouldn't either.
"You need to discover what we left out of this theory" All of the people who watched this great interview is going to suffer anxiety attacks night after night
Cosmology would be boring if we already had all those answers discussed at the end there.
very confused about this CMB. A form of light emitted at the beginning of the universe, and stops shortly thereafter...
if the big bang is true, and was a singularity, then the CMB light was emitted eons ago from that singular point, and zoomed away from the singularity at the speed of light, then matter appeared. Now, I know when I turn off my flashlight, the beam doesn't just vanish, it's just not being emitted anymore - the beam continues basically forever. just like the light that created the CMB...yet, somehow...you can detect it? ChatGPT tells me it "permeates" space, but if that's true....then...the CMB can't be light...for light doesn't just stop in its tracks. so how in the devil are you all able to detect it well after it's been emitted? is the CMB truly a form of light?? input - more input! :)
Nice
Could larger galaxies in the past indicate a more linear non-inflationary universe?
Was this interview part of the festival, or was it the entire festival?
The moment a particle is a wave; it has to be a conscious wave!
Gravity is the conscious attraction among waves to create the illusion of particles,
and our experience-able Universe.
Max Planck states: "Consciousness is fundamental and matter is derived from Consciousness".
Life is the Infinite Consciousness, experiencing the Infinite Possibilities, Infinitely.
We are "It", experiencing our infinite possibilities in our finite moment.
Our job is to make it interesting!
I just learned that nearly 1% of the static you find in old televisions is from the cosmic microwave background radiation. It used to be an irritant. Now, I am constantly in awe of it as I realize its connection with the Big Bang. It's no longer some random signal from the void. It's home calling out to us.
6:10 .. Wow! Rich story.✍️🙂
I write on Abiogenesis. Interested?
7:54 .. You immediately won my heart saying you are theorist. I love that. I was trained in lateral thinking. Apparently I'm an existential ethic. I write about our makings. Truth is not just stranger than fiction. It's a lot more funnier, and sometimes more terrifying. There are things that I can't write. Like, god may be 'loneliness is hungry'. It's like we are in a mouth. If the universe are the two things, E=mc² & proximity + instantaneity (abiogenesis), and we be tendrils of sniff searching for safe crevices, &, ..well.. maybe come and read my latest work. E = mc² is tongue. Proximity and instantaniety may be mouth. Black holes are teeth. The sun is nasal cavity. Behind sniff, & in front of it, because sniff was all we had before time spun When black holes shattered self-healing reality. To sniff where safe crevice in space before E=MC² . That we smelt, was a testament to that we would smell. Basically, smell and taste are on opposite sides of one another, and betwixt them is the ticktweentime gap between you and you, which also happens to be also the inner-sharp-shard-star path of ever altering predetermined fate.
Absolutely I am talking about smell in regards to marking territory.. .. Let's go Let's go, I can't wait to show you what I've got. Take it. It's heavy.
I write about the relocating earth. We move. I think it's about time scientists stop expecting free writers to pay for our writers tech. I absolutely think you're going to kill us. You don't take care of your writers . We're in big trouble. I'm beginning to think, no matter what you do, I will never look at you the same way again if you don't help us. At least, we need better Google microphone. We've got something that feels to me like a gimmick from some show bag . Sometimes, I die inside. You are so neglectful.

.....Tycho Brahe lived between1546-1601....
It is simple. Prof Neil Turok has a theory that solves numerous issues including but not only Dark Matter.
It is the Universe/Antiunivers pair. Prof Turoks theory makes testable predictions.
Cosmic Microwave background cannot be presently Standing in one piece against an Expanding Universe.
Even more qualified is this Universal Law, the Stronger Energy Flow overrides the Weaker Energy Flow at all times, which certainly would've destroy that Cosmetic Microwave background.
What is he speed of darkness?
You guys need to do an *experiment.*
