Dark Matter

Papers
  1. -Has the Majority of the "Missing" Mass of the Universe Been Found? (Time.com)
      "As you might have heard if you pay attention to these things (and will be distressed to learn if you don’t) up to 80% of the matter in the universe is simply missing. The Milky Way spins so fast it would fly apart if the gravity of some invisible matter weren’t holding it together. Clusters of galaxies, buzzing around one another like angry bees, would similarly fragment and disperse. And when you run the gravitational numbers, the mysterious matter that keeps all that cosmic disintegration from happening should outweigh the familiar stuff by about four-to-one."

      "Just as researchers working at Europe‘s Large Hadron Collider last year announced that they had bagged the Higgs Boson, so did investigators this week reveal that they’ve found compelling evidence for a type of theorized particle known as a WIMP—for weakly interacting massive particle—and that at least one form of it may be the dark quarry they’ve been hunting for 80 years." 04-13

  2. -Scientists Search for Dark Matter With Hadron Collider (PBS.org)
      "The massive particle collider runs in a 17-mile circumference ring under the Switzerland-France border. In 2013, physicists used the high-energy particle smasher to find the elusive Higgs boson. The Higgs boson explained why particles have mass, an idea first proposed in the 1960s."

      "It was a monumental achievement for the field of physics. It was the final piece in the Standard Model of physics, the theory which describes the particles that make up the universe and the forces between them."

      "One mystery physicists hope to unlock in the next phase of experiments is dark matter. Scientists estimate that dark matter makes up 85 percent of the universe, Mike Lamont, operations group leader for CERN, told CNN. It’s invisible, and it would explain effects physicists can observe on radiation and visible matter in the universe." 3-15

  3. Dark Matter (Wikipedia.org)
      "Dark matter is matter that can't be detected by its emitted radiation but whose presence can be inferred from gravitational effects on visible matter such as stars and galaxies." 10-04

  4. Dark Matter Filaments of the Universe Uncovered (Christian Science Monitor)
      "Scientists have long thought that threads of dark matter provide the underlying architecture upon which galaxies in the universe are distributed. A new study now verifies that theory."

      "Three-dimensional astronomical maps developed since the late 1980s show that the vast majority of the universe's galaxies are distributed as threads and sheets that span the universe, with galaxy clusters as well as superclusters of thousands of galaxies appearing where threads and sheets intersect. These structures were thought to have formed on a framework of dark matter, the unseen form of matter that scientists believe binds galaxies together."

      "The results announced Thursday mark 'the first time we have observationally verified this very important theoretical prediction' of a dark-matter backbone, says Jörg Dietrich, an astronomer at the University of Munich Observatory in Germany who led the team." 06-12

  5. Dark Matter May Reveal Extra Dimensions in the Universe (Nature.com)
      "Welcome to the fourth dimension. And the fifth, and the sixth. A team of astrophysicists claims to have identified evidence that space is six-dimensional." 9-05

  6. Stange Lump of Dark Matter Found (Space.com)
      "A lonely clump of dark matter 2.4 billion light-years from Earth is confounding scientists by its mere presence, researchers say. Contrary to popular astronomy theories, the invisible stuff appears to have been left behind in space after a cluster of galaxies collided." 03-12
