Physics in the Dark: Searching for Missing Matter

  • If you believe the world’s leading physicists, the vast majority of matter in the universe is hiding in plain sight. For nearly a century, evidence has mounted that the gravitational pull necessary to keep clusters of galaxies intact, as well as stars within galaxies from flying apart, requires far more matter than we can see-matter, according to the experts, that has eluded our telescopes, because it does not give off light. Problem is, such “dark matter” has also eluded one specially designed detector after another that researchers have deployed to catch it. Which raises the big question: What if we have failed to find dark matter because it isn’t there? Join leading physicists on a scientific treasure hunt that has proved more challenging than anyone expected, and may ultimately require rethinking some of our most fundamental ideas about the universe.
    This program is part of the BIG IDEAS SERIES, made possible with support from the JOHN TEMPLETON FOUNDATION.

    Brian Greene is the best physics panel moderator because he's an accomplished physicist. Many times I have seen him gently bring a bickering panel of scientists back to the topic at hand, which is only possible if you understand the topic at hand.

      Atheists And God Worshipers Live In Deceit
      Truth Is Existence
      Truth is All That Truly Exists.
      Other Than Truth there is Just The understood Concept of An Absence.
      Lies with intent to deceive or not is fantasy. Lies remain in the nonexistent realm.
      The Great Designer and Creator, Matter, Knowledge, Energy, Time and Space Has Always Existed.
      All Without Beginning or end.
      Beginning and End only reveals an absence.
      Creation is only the rearrangement of Matter. As Existence and Matter does not evolve from nothing.
      Spirit Is The Highest Energy Source.
      Gods Are Imaginary Personages Of Worship, Gods are Fantasy!
      Gods are not creators. There are Hundreds of Gods that the human has worshipped.
      The Great Creator is far more Massive and complex than the God worshipers realize and understand.
      The Great Creator is not a being somewhere in space.
      The Great Creator is a huge mass of spirits in perfect unity. And with the same care for each another.
      Words to the honest and wise: honesty and understanding is the only true belief. Without honesty and understanding we do not know what to believe.
      To accept other’s opinion of the truth without proving it to yourself; it is being deceived it is not believing.
      We must understand to believe.
      Until Next time: Sweet Dreams: Truth will solve all our problems before we create them; and ignore or reject the truth; problems will multiply all by themselves; those problems will need no help.
      Have a great and a meaningful life if it is at all possible.
      Just whispers, of the Spirit of Reality.

    I love this panel style of explaining theories... If you just watch one person being interviewed, or a documentary of like minded scientists, they often say something like, "This is how we know that is, or is not the case... and that is the way it is".
    This way you see the emotion involved in the theories and there are other views and it's all incomplete. Much more informative in an important way.

      I don't like DM, at least in the way its been conceptualized, and I like alternative views as well as Erik's. But his theory has many problems and is most likely wrong. It's crazy to me how DM as a particle is either totally wrong or of an energy scale that we can never achieve yet no one will quite admit it BC they want more funding. And so the charade continues at the neglect of more important studies where all this funding could be routed. The DM issue Is so complex. They find Galaxy after Galaxy where there isn't any DM at all. But it's also very conceivable that it+' mass is too large for us to recreate. I think our understanding of gravity at large scales is incomplete..
      I sure brought a different point of view didn't I? No one spoke of these ideas before me! N

      Not so easy for nonsapiens, so please consider this...
      Spacial distortion bending the path of light, also distorts the frequency of light emitted from super heavy distant galaxies.
      Gravity from distant galaxies has a redshift effect on the frequency of light they emit in the same way that gravity can bend the path of light from a light source behind the gravitational field.
      Dark energy is an illusion caused by a spacial distortion caused by the gravitational fields of the distant galaxies emitting the light.
      Hence no cosmic acceleration, no dark energy causing acceleration, no unaccounted for dark matter, and certainly, no big bang. This universe is eternal, without beginning or ending. Cosmic background microwaves are but distant galaxies who's light has been gravitationally distorted beyond your visible spectrum.
      Galaxies continually exchange and recycle energy and birth new stars out of old dead ones for ever and ever.
      How do you think light escapes super heavy distant galaxies with its frequency visually unaffected by spacial distortions?
      Someday sapien's evolutionary decendents might survive travel to distant galaxies and discover the return trip doesn't take require extra travel time, as no acceleration is actually occuring.

    Really excellent moderation allowed an equal taste of all these different theories trying to account for one of the greatest mysteries of our times. As an aside, perhaps one day these brilliant minds will come up with an explanation of where socks go when we put them in the dryer. We know there is a basic symmetry to socks - they always come in pairs. Yet when they come out of the dryer there is always an odd one, breaking the symmetry. Energy must be involved in breaking the covalent bond between the pairs of socks, and we know the heat in the dryer must play a part. This also has implications involving information theory and entropy. Perhaps the answer lies somewhere at the intersection of supersymmetry and string theory.

      This has been tested. If you put them in the dryer all together in one mesh laundry bag they found you never lose any! Also if you were to check the grommet around the dryer and even sometimes the washer you may a couple. But they never truly disappear just collect in a tough to find spot or you never actually put them in but thought you did.

    I was a little puzzled that the intro notes made no reference to the fact that this talk was filmed on the anniversary of the solar eclipse of 29th May, 1919, as observed by Sir Arthur Eddington and colleague, which was very significant, because it was the first observational proof of the validity of Einstein’s theory of GR.

    My last comment about a standard model of space is influenced by the hypothesis some physicists have that first there is Inflation and then there is the Big Bang. That hypothesis implies empty space expanding then time, matter and energy emerging. If that hypothesis is true then it's more important to focus on space than on matter.

    4. n = number of superpositions
    And you get dark matter

    m = 0.3313 10^18 10^-34 = 0.3313 10^-16 kg ( all superpositions).
    1 particle = 0.331 10^-16 / ( 0.4 10^18) = 0.828 10^-34 kg = 46 eV

    I recently read an interesting article--In 1920, lecturing at the University of Leiden, on the topic "Ether and the Theory of Relativity," Einstein stated outright that the ether did exist, that it was necessary as a medium of transfer because light also had wave-like properties. He even wrote Lorentz to clarify this point. But by now, the damage had been done. This lecture received little notice, it was ignored in Roland Clark's watershed biography on Einstein published in 1971, and so the 20th and early 21st centuries evolved in such a way to dismiss entirely ether theory.

    Start focussing on the fact that time could have mass. This will lead us to what dark matter is as well as give us a clearer indication as to what gravity actually is and how we should treat time fields around objects of matter/mass. Time, Mass and the Higgs Boson are inextricably linked to Gravity and each other but it is not in the way most physicist are thinking. Dark energy is going to be a shocker of some kind because it looks like it may play into the Einsteins General Relativity and the tweak needed to his equation.

    Thanx Dr. Green, as always very good job in the explanations of the matter.
    I found some interesting numbers that all apply to GRAVITY some way or the other, some times gravity is counted as adding the 8 in the disc. The periodic table as well is counted by adding the 118 places, as well I added the mass of each group: METALS, NOT METALS AN METALOIDS. I did the same in 2 other forms to see later.
    The numbers could go UP and DOWN so the SMALL and the BIG is no problem.
    77.86 is the gravity of THE 8 PLANETS IN THE DISC and if we add the SUNS GRAVITY(274) =
    351.86M/S2 THAT IS THE SOLAR SISTEM GRAVITY and 3.1416/351.86 = 112.00025.
    112.00025/300000KM/S(LS) = 2678.5654/89.28 = 30.001852.
    89.28 is the result of 351.86/31416(is a number very common all over cosmology METRIC based) as the coming exemple:
    149.6 millions of Km. for the sun light to reach earth times 210(common number) = 31416(is the PI 10000 times).
    31416 is what you get whene you add the three faces with the ones the UNIVERSE WORKS in my first book in Hz that could go UP or DOWN as needed for a system to work:
    10920 IS FULL FACE/3141600 = 287.6923/144(# PHI) = 1.9978631.

      William Peterson Perhaps so... but the concept of there being a _single_ external objective reality that we all share _ought_ to be a fundamental underlying principle of _all_ facets of life, not just science. and now even science has become corrupted by the intrusion of politics in areas such as Anthropogenic Global Warming Denialism. It is important to show the concept of objective reality being applied successfully in scientific research, and the same concept ought to be applied in politics, journalism, the rule of law, and in the study of history, for example. This should be part of our standard education system.
      The recent trend toward relativism, obfuscation, conspiracy theories, and outright serial lying poses an existential threat to the stability of our society. This danger should be apparent to _everyone_ not just those who seem superficially to benefit from it in the short-term. Science can serve as an example that multiple realities, if they exist at all, may only be relevant at Quantum scale, and should not be invoked in a cynical political strategy intended to promote confusion and divergence of "worldviews" within our culture.

      MendTheWorld Hmm.....Trillions Of visible, invisible layers of stuff? With trillions of trillions of Connectivity? There is no difference between any layer of stuff! And-Just paid experts? Giving an opinion, of where the Tree is rooted. By the roots in the ground or rooted by the branches in the invisible ether! There is something quite dramatic that being in the rut of a percentage of 5% Known, drawing conclusions about the 100% Unknown unknowables Which seems archaic! The impeachment inquiry and Dark Stuff are the same thing, it is Incomplete Understanding Of Anything.....So it does not matter what you watch, it is watching You anyway, by hook or by crook!

      i saw a video of him on entanglement that is done in a wrong way, matter entangles from north to south as seen in ALTON HARP INTRINSIC RED SHIEFT as well in the video THE FLOWER OF LIFE OR DNA DECODED Alton shows the MACRO mine is MICRO and is DNA,

      @@lancetschirhart7676 THANX a lot LANCE for correcting me I am realy bad in spell but I think now I am better than before started readdyng peoples coments, HALTON ARP is been of so much help to understand better my universe in the video HALTON ARP INTRINSIC RED SHIEFT where at first I wonder or though of ENTANGLEMENT AT ALL SCALES that is a video in you tube and the entanglement is done all around in 4 orbits if not broken light and 8 if light is broken, in the video of HALTON ARP you can see how 2 pairs of quasars are entangled to a galaxie, there are too systems with many pairs of quasars relating to a claster of galaxies that to is ENTANGLEMENT in it found that south side brakes more than north cause south side always opposes more resistanse and are the rocky ones the north side are the gaseous so north is positive and south is negative they are 2 one another in pair cross section. Here I new of the 7steps in wave lenghth that to me is the order of the universe that is like a rainbow araingement that fits the TZOLKIN Mayan Calender as orbits that to me are herts but some times seem like matter and any thing you wat to know in physics might be there.

    The whole panel was excellent but @1:08 where Eric shows the graph and says "the critical value [where the expected vs observed rotation rates diverge] is connected to the expansion rate of the universe" --- now THAT really got my attention.

    These people need to actually read Erik's papers, which are great and actually reproduce general relativity - with corrections that add the extra gravity that is ascribed to dark matter.
