  • 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.

      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.*

    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.

    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.

    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.

    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.

    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.

      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.

  • @Jason-gt2kx
    @Jason-gt2kx 6 років тому +7

    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 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.

      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.

    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!

    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 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.

    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.
