Shedding New Light On Dark Matter: Brian Greene and Priyamvada Natarajan 

With the world and politics being what it is today, hearing conversations like these between brilliant minds is comforting, and reassuring. Thank you.

Priyamavada is amazing and she is very clever in her explenations so a layman can understand what she is describing, never seen Brian so scilent thou 😅 Wonderful conversation on dark matter, so much information my head is still spinning a bit, i have to digest this over time. Huge thanks for making this availeble to the general public for free, you are true heroes.

This two hour format was quite enjoyable and succinct. Your guests are always interesting. I love sharing the link with my friends, and watching it again again for a better understanding. You cover a lot of ground with each live stream! Muchas Gracias from Miami :)

What a wonderful conversation between two brilliant minds!

Yes. I definitely believe that there is other life out there. It depends how you define intelligence. If you are thinking about self awareness and communication systems etc., yes I still believe it exists somewhere. The question is, at least for lower species, would we recognize it as life?

we are evolving through time

Brian what a great dissection of metaphysics and thank you for separating analytics from theologic ruinations. Both are important, but all we can use as mere mortal human beings to analyze the universe is our physically limited analytics. Whether there are multiple dimensions or multiple universes, We will never know. And even the mathematics and physics are limited by our own interpretation and experience of them. But I think it’s important to distinguish between reality and theology.

Novel Dark Matter Hypothesis Dark Matter is simply unaccounted for gravity. GR states that gravity is the consequence of the curvature of spacetime. Is it possible that the structure of spacetime itself could be warped without the presence of mass? Spacetime has been shown to react like a fabric by warping, twisting, and propagating independently of mass, and all have been proven with observations from gravitational lensing, frame dragging, and now gravitational waves! Fabrics can be stretched, pressured, and/or heated to the point of causing a deformation. All of these conditions were extreme during inflation, so it is plausible that the “fabric” of spacetime analog could extend having its elastic property have hit a yield point. Therefore, if gravity is the consequence of the warping of spacetime, and fabrics can be permanently overstretched, then those empty warped geodesics would create gravitational wells independent of mass. My hypothesis of DM is subatomic black hole imprints of the quantum fluctuations that popped in at the moment of inflation. These would be clouds of quantum sized floating fixed geodesics, so they couldn’t expand or evaporate. Perhaps nothing has been detected because there is nothing to detect, and GR wouldn’t require modification of mass interactions because DM would just be an extension of how space-time behaves at extreme conditions. No WIMPS, no MOND, no parallel universes, just empty spacetime deformations that produce gravitational wells to help jump start galaxy accretion processes.

I am sure glad that you both take the time to reach us normies. There is more public interest in these topics than ever and we need you all to explain them in ways that we can understand. Much appreciated.

What symbol is the actual thing. The word "tree" is not a tree. Not ever. There is only ONE BIG thing that ever was "going on". Math never deals with this unless infinity speaks to a fraction of itself. Same as all "language". Nothing sums up.

Streamed two years ago??? Omg I have got to catch up with this incredible lady!! Wow!

THE MOON landing MIGHT BE A JOKE TO.. 👈 😮😯... THEY LANDED on The back side of THE MOON... SO NO live CONNECTION WHIT EARTH.. RIGHT... 😂.. NOW GO watch THE live version... WHERE Armstrong TALKS... 👈😮LIVE WHIT Houston.. 😮.. MAJOR MISTAKE.. Smart boy, s😂

🤔 BUT WHO is PLAYING THIS SYMPHONY of sound AND LIGHT 👈.... COS sound CREATES mass AND PATRONS.. AND WE ALL KNOW WHAT Light DOES... Bhot goes hand in hand WHEN needed... 369 God is GREAT 🙏🏽🙏🏽🙏🏽

Shedding new light on dark matter with Brian Greene and Priyamvada Natarajan 2:09:27. ⭐️⭐️⭐️⭐️⭐️

21:15 The good professor describes a ficticious debate between David Albert and Donald Trump. That discussion reminded me of the part of the movie "The Forbidden Planet" when Dr. Morbius brought the Doc, and Capt. Adams into the Krell laboratory and used the "plastic education" on each of them. The others had IQs in the genius range but the caption's IQ was "normal". Professor Morbius then said to the skipper something like: "oh well, I guess you don't need brains to be a good commander"........

1:10:00, So someone should not be allowed to be themselves just because You think the person is a jerk? It sounds like she's the intolerant one in that equation.

what the future of universe? it's every matter decaying ? how about dark matter it is decaying to

Brian Greene and his science sessions are fascinating, informative, entertaining, and articulate. You can't ask for much more than that!

Thank you Dr. Green . I always learn something from watching you

Sir.. you are such an inspiration for us... Thanks a lot...❤️❤️

This was a lovely discussion between you two. Thank you Prof. Greene ♥️♥️♥️

No political views please. We are all well aware.

Very intelligent & interesting discussion thank you for sharing. Actually dots are connected but it’s hard to put in words I sat in long silence meditation 🧘🏻‍♀️ it takes so deep I see visualize pyramids & my third eye 👁 takes me so so deep it’s so deep .. beyond time & place experiences. No language can explain :)

The theory also suggests, by consequence, that these extra dimensions are made of some form of energy, or its equivalent ‘glue’, but by the same token the feet that walk upon that ‘glue’ must also recognize it. The ant must have components that recognize it built into the soles of its shoes or the dimension will be so dark it won’t matter!

If the extra dimensions where connected from manifold to manifold (knot to knot) by a string of energy (of that dimension) then it may well look like quantum fluctuations in the vacuum energy density.

Wow. My ears hurt from listening to her

The "Ring traps theory" from 2019 Provides a consistent model, what Happens with knowledge, and how it comes to universes seemlessly, even in accordance with godels sentences.

Excellent discussion on dark matter

EXPLANE THE PHYSICS of THE 911 ATTACKS in 2001.. I REALLY LIKE TO KNOW... OR is IT COMMING TO close TO YOU AND THE TRUTH COULD HURT YOU hmmm🤔... IGNORE ALL YOU WANT.. BUT THESE QUESTION WILL NEVER GO... B4R...

Priya ma'am is a gem of India who deserves a lot more recognition

Of course there is life nope. look at the microscopic and Macroscopic

A course on General Relativity like the one you had on Special Relativity would be such a gift to the world. Your Special Relativity course is just amazing and so well done. it would be something wonderful to see you do that same kind of course on General Relativity even if the mathematics would be tough to follow. I would not care and neither would most people watching it. I TRULY HOPE you do it. (fingers crossed)

I love this discussion thank you both very much

I was thinking one time that dark matter was the thoughts of all living things. Somehow thoughts never die and they go into the thoughtosphere. I recall Einstein saying something like it wasn't his thoughts and he tapped into some sort of stream of thoughts. Maybe i made that up idk but it was a pretty cool thought I had

What a great presentation, nice explanations mostly only verbally.

We may find that it takes an entire universe to incubate one earth, considering how fine -tuned the conditions for life seem to be. Maybe it takes trillions of planetary systems to make just the right combination.

Thank you both for advancing human knowledge, and special thank you to Brian Greene for making sure that this is shared amongst us!

I love Priyas work and explanation of how she's gotten to where she is now with her understanding. Absolutely amazing.

24:39 The one-over-zero curvature model depends on whether you’re talking about kinematic vs inertial reference frames of the observing researcher. This is because in the inertial reference frame, you can have division by zero due to the effect that being stationary has on the equation velocity = distance/time. When rearranged to Time = distance/velocity where T ≥ 0 at velocity 0 making the “undefined” condition of can’t divided-zero, in this instance, not mathematically undefined but actually zero as far as inertial reference frames are concerned 😹

It is interesting that wherever you find gravity in concentration you also find the bending of space nd the slowing of time, suggesting time is being bent as well. But matter is charge, Either positive, or negative or neutral (Balanced) as in the neutron, but its still charge er unit volume. Thing I can’t square is electrons are spread out over a much bigger volume than protons, and this imbalance gives rise to the emergent property of gravity.

Hi Brian, can dark matter consist of these virtual particles that constantly pop up and disappear in empty space?

50 years ago when learning Calculus, my teacher told me that ONE OVER ZERO IS NOT NUMBER BUT A CONCEPT, it seams that new generations are not thought in the same way

Gracias Brian, really appreciate you sharing your time and knowledge in these difficult times.

Life didn't "happen", all forms of life were created by God with the ability to replicate. Man was created with enough intelligence to know that they were created by God. Those who reject that knowledge will spend an eternity in outer darkness, the God they chose to worship. Eternity is a long time to waste, choose wisely.

Thank you for yet another effort to bring out of the views of working scientists

Speed of dark, well I contend it's infinite because dark is ubiquitous. Imagine if the roles were reversed, dark had the speed limit of light (or a speed of some decay factor of light), and light was infinite speed, then light would be ubiquitous and whatever light decays at a speed darkness will result. Just another universe rules to imagine 😜

I'm still going with DARK MATTER being older then the Universe's physical matter. Could the birth of our universe be the birth of the 4rh dimension, thus the 3rd ( and by definition) was in existence prior (or always exist) as it is void of time. If that said be true then as our visable physical universe moves thru this 3rd dimension be DARK ENERGY itself. A static electric charge (not unlike rubbing your feet on the carpet ) Just a thought that came to me a year ago.

Not enough talk about dark matter... but I already have that figured out! Dark matter - 1. Lots of it, which I believe was the stuff from which our universe sprang. 2. Undetectable - really interesting - 3. Passes right through us and the earth, without interacting. 4. Holding galaxies and clusters of galaxies together, through its massive gravitational influence. Here I want to induce everyone to think about the density of dark matter, what the possible states the early universe might have been in and how changes to dark matter density might happen during the universe's development... More to come...

Understanding infinity depends on our perception of time. Tomorrow is just another day, but what does it matter? 1/7= .142857🦖

Genesis 1 verse 2 says in part …and God’s Active Force Was moving about ….. If they think about this , they may understand . This force holds everything in place in galaxies and expand The universe too . Dark matter and dark energy

I always wondered if the fuzziness of the quantum world is due to the quantum world being small enough to slip in and around and out of these extra spacial dimensions, but at the macro scale we can only perceive the larger 3 so we don't look to be moving around through all the extra spatial dimensions.

41 year hi Inflation and going into Recession. Afghan withdrawal disaster and fast rising crime rates and on the brink of Nuclear Holocaust. Please give me Trump back.

I want to ask about a particle's relationship with the environment. Whem the particle iitself expands, space must expand. Other than classical movement there is another way of motion! Growth. Is thatt snother axis?

i love your work Brian , im hungry for understanding i appreciate the free content being a Disability Pensioner on limited income

MUST they always bring up colour" or some form of racial aspect", its sickening, it just shows over and over where the REAL Predjudis lies.

there's zero pain in "dying" the chemical reaction ;) you just go out and remember it maybe sometime later. to what extent, well there is no I ego nor death. PARABRAHMAN but MAYA I i I AM what am I particle Matter cannot be measured; truly WHAT AM I. death die to I measure I show me and did I Brian Love You sorry kinda implied a sellout but you in the mind and spirit three six nine outside the box. Tesla, Nikola My Hero time travels' possible. so how to explain well come see me but i we need a new math working on it. OM. Namaskar. Douglas

It probably incredible arrogant for humans to put that question are there other intelligent species like us out there. We are only an advanced predator species who has very irrationally and not intelligent managed to bring ourselves to the brink of existence and possibly extinction. We have managed to make the overwhelming majority of our species suffer more and more. All because the few who managed to arrive at privileged positions have only one interest, to further their own advantage and dominate over the rest. In America this behavior is actually a sign of advanced intelligence and the only criteria for evaluation as a quality. It may be possible that somehow a small group of supreme wealthy and privileged humans survive in some underground bunker or in some space technology. But I suspect that their supreme predatory instinct will further reduce their number, simply because competition, greed and dominance is the MO. I do no believe that other more advanced species in the universe will allow humans to contaminate realms away from their origin. Maybe there is a path for the few individuals who actually possess true empathy and practice it, as unsuccessful as they may be in their environment, can have a place in the community of advanced species through some form of mind transfer, soul transfer or whatever one might imagine. But basically humans as a dominant species on their planet violate a primal rule of any species, not to contaminate and destroy their own ecological support structure.

I see some people are easily impressed. However, I did find the information about the simulation code fascination. I wonder how modular the code is and how much hard coding is necessary. The data libraries must be immense and I suspect it's classical rather quantum simulated hardware. Was used I'm encouraged that some aspects of dark matter is being nailed down.

If they don't know what it is they are talking about actually is, then what makes it matter ? How convenient is it that this dark matter that doesn't interact with matter we can see test and detect would have ONE exception of interaction, which would be gravity which is not very well understood to begin with and account for the "missing mass of the universe" that would now render their calculations and predictions correct. This claim by itself cannot be taken seriously at all ! And if it was actually matter, then when you're walking down the street, you should almost always be running into a wall of dark matter ! This is not worth the time to even waste 1 second thinking about it

...a bit too many interruptions of the guest speaker by Brian made it difficult to keep continuity of concepts and argument. Otherwise, very challenging and illuminating...

Your speech is very important you speak about science and religion.can you explain with scientific evidence how to explain the miracles of saints of our church and how the holy water is always good!!?

Good day, thanks 🙏

Is it remotely possible that the reason dark matter can't be detected is because it's time matter? As objects of density occupy and move through space, is it feasible it is 'rubbing' out Spacetime particles which may be amassed into and construed as dark matter? How bizarre is that?

The assumption that spinning galaxy should throw off stars is an error of the nature of inertia. The gravitational platform is the prime reference. The moon has inertial motion wrt the earth's surface. We who are on the earths surface every day rush at the moon, stop, turn and rush away with no sense of inertial change, because we are on the gravitational platform of the earth, and unless we move wrt the earth, there is no inertia tossing us around. Galaxies that spin are in their own platform and so thinking that they are in an inertial motion that should spin off stars is nonsense. Gravity is a field that connects al mass to all mass, and is checked by motion. It is the light carrier. It is the fabric on witch all time vibrates. Its density is never homogeneous and that is why light bends according to the gravitational structure of the local, & why "in a vacuum" gives no pertinent info about the light conveyance.

Reflective energy and geometry is interesting Save my thoughts for the future ! Still looking for the man of East and West A Divine Joke !

Why did he chose to answer all of the dumbest questions... Especially when there would have been multitudes of intelligent inquiries ???

It’s wonderful to learn English listening Brian Greene speaking about that matter.

There is most certainly intelligent presence that is not of planet earth. Philosophically we must define life. The question arises whether high intelligence (far exceeding humankind) can exist as a non physical entity.

Wow! could you guys stop poking around into space. Odds are we're not going to find aliens before they find us. And we probably wont be top of the food chain anymore.

Life on Venus & we are talking bacteria wouldn't be so surprising - it would be very, very strange that life evolved in this one planet - if the conditions are right, life should evolve anywhere! So Dark matter wins the contest

If you wait around forever something might eventually happen....this is known as the door knock theory.

Is it possible UFOs dwell/ travel on black matter ? And to top it, Quantum tells you matter can be in two places at the same time ? Is that within realm? Anyone at it?

Life on Venus? Wasn.t Valiant Thor that worked with the U.S. Government for 27 yrs. from Venus ?

The bewildered criminal locally perform because spider phenotypically drum near a garrulous australian. marked, historical okra

David Albert talking to Donald Trump = Einstein talking to an ant. LOL Bazinga

2:05 - "invisible stuff" like God? lol When will this go away? All it takes is to make a cheap promise of an eternal life of pleasure and people are willing to throw their own brothers & sisters, even mothers and fathers, into gas chambers in hell

Let me ask you a different question. What if our planet WAS the only planet in the universe with intelligent life? What would be the odds of that?

it was a wonderful session professor Brian Greene..can you invite Elon Musk to discuss aerospike and Edward Witten to discuss more about String Theory!! please. ALSO YOU ARE NEVER OLD FOR ME..ALWAYS THAT THEORETICAL PHYSICIST WHOS IS EXPLAINING THE GENERAL THEORY OF RELATIVITY IN THE BEST WAY HE CAN......!!!!

Why if light is massless, can it be bent by a large mass? In black holes light cannot escape. Therefore light should have mass.

Brian Greene looks like he might have smoked a joint before going online? - I’m not saying that’s the case I’m jus saying das all

As far as math is real instead I believe in Plato's dimension so ya. It makes sense to me that the pattern abstracts are more real and this dumb material are just emanations of that.

😭I had read RB story 50 years ago, still is one of the most sad stories I have ever read, even today I remember it

please invite Alan Guth!

So we could be dead and alive at the same time considering eternal life in paradise where it will be a point in time that we never realize we ever left from there in the first place?

Our math is based on observations of the universe, if the universe was different our math would be different, so based on that, math is “out there”

How does math that was not even discovers until we have arrived we as in person so how is math this huge proponent of matter to our world. I think it’s great but how is it the best thing we have to offer.

I do believe there's life out there...somewhere

I love your observation on influencing people as opposed to a handful of specialists.

The woman’s are the mother of our nature’s, and more closers to the truth of our existence so they are capable to know more from universes.

If we can't see these extra dimensions but a microscopic creature can walk in them, shouldn't the creature also disappear? Isn't that a way to see whether these dimensions exist or not?

You do not think how to find this is nature others find not giving time to talk but I like you .I know whats your question but answer is in not right

Love to see rise of My Indians people!

Another thought provoking subject ur expertise is compelling Like ur eyes

To me there’s a 100% chance we’re not alone 👽. The universe is WAY too big.

Dark speed is much more than speed of lights, as before the lights gets to the distances, then dark is already there !

Wonderful discussion, thank you. Could you invite Jim Al-Khalili on and talk about quantum biology? It's extremely interesting, and he's also an excellent teacher.

8:30 they come when we don't deny or hunt them, as with each other and getting that which we give; super sonic.

If you consider a painting, You can with all the math available, describe the painting, but can you use math to tell me what it conveys to your feelings?

Undergraduate thesis with Alan Guth!! Sheesh! What a name drop!!
