Scientists are closing in on dark matter

New research on one of science’s enduring mysteries


 

(NASA/European Space Agency/AP)

The first results from a particle physics detector aboard the International Space Station are in—and show tantalizing hints of dark matter, a mysterious substance that binds the galaxies together.

New research from the $2-billion Alpha Magnetic Spectrometer (AMS), revealed today by Nobel laureate Samuel Ting, confirm an excess of positrons (the antimatter counterpart to an electron) that could very well be a sign of dark matter particles annihilating each other in space. Then again, maybe these signals are just some cosmic debris, although scientists are cautiously excited.

“Over the coming months, AMS will be able to tell us conclusively whether these positrons are a signal for dark matter, or whether they have some other origin,” Ting said in a statement.

Since it launched to the Space Station in 2011, the AMS has recorded about 25 billion cosmic ray signals, including the largest collection of energetic antimatter particles ever measured from space. Scientists predict that collisions of dark matter particles produce positrons and electrons, which is why the ratio of these tiny particles is so interesting to dark matter hunters, Ting included. But we still don’t know for sure if the positrons AMS has found are from dark matter, or  something more mundane, like pulsars. What the AMS has found “is an indication, but by no means is it a proof” of dark matter, Ting told New Scientist earlier today from a seminar at CERN, near Geneva, from where he presented his results.

Still, an indication is exciting enough. Ting’s results had been hotly anticipated for months, and in February he teased reporters with a promise that news was coming soon. “The Cosmos is the ultimate lab,” he said then. While scientists on the ground continue the hunt for dark matter—at CERN’s Large Hadron Collider, for example, and at SNOLAB, deep underground in Sudbury, Ont.—this massive orbital experiment, which continues until the Space Station is decommissioned in 2020, looks to be quickly closing in on one of the enduring mysteries of science. Dark matter makes up about a quarter of our universe, yet we know almost nothing about it; many predict we’ll have found dark matter within the next ten years. Maybe sooner.


 

Scientists are closing in on dark matter

  1. They’re fiddling with the data again. This is simple background noise, cosmic radiation, the lingering remnants when matter started to coalesce after the first few seconds of the Big Bang Theory. Just a good story. Nothing of any real consquence.

    • yeah, the nobel laureates would never have thought of that.
      /sarcasm

      • Yes. Sarcasm is deep. Very profound. Glad you could take the time from your paper on astophysics to weigh in on the subject.
        Irony is obviously not your strong suit is it pretentious?
        . .

      • This is not really my field. I’m trying to determine the field vectors for extrapolation points.

  2. ahhh, and the scientist’s are cautiously excited….

  3. You lost me on this one

  4. There is no dark matter. The expanding universe can be explained else-wise. There were two big bangs. The first was significantly larger than the second. The outer reaches of mass (or pre-mass) of the first big bang expanded temporarily. Mass nearest the origin collapsed back to a new singularity and exploded again, the second big bang. We are part of that second event. The total mass of the first event was great enough for it to eventually collapse, which is what it is doing now. Our second event “universe” is being drawn out, faster and faster, by the gravity of this encroaching shell. The light from this “Outerverse” has not reached us yet, but it will, and suddenly. Then there will be a new sky, unlike anything we could have imagined. There is no dark matter.

  5. Confirm Dark Matter?

    With utmost sincere respect, dark matter and dark energy
    may be found only in some human minds. Energy is mass in motion; as the galaxy
    clusters move since inflation their mass decreases as their travel distance
    increases. Thus ALL mass and energy are accounted for.

    Dark energy and matter YOK. They simply do not exist.

    All The Mass Of The Universe Formed At The
    Pre-Big-Bang Singularity

    The universe is a two-poles entity, an all-mass and an
    all-energy poles.

    The elementary particle of the universe is the
    graviton. The gravitons are compacted into the universal inert singularity mass
    only for the smallest fraction of a second, when all the gravitons of the
    universe are compacted together, with zero distance between all of them. This
    state is mandated by their small size and by their hence weak force.

    The big bang is the shattering of the short-lived
    singularity mass into fragments that later became galactic clusters. This is
    inflation. The shattering is the start of movement of the shatters i.e. the
    start of reconversion of mass into energy, which is mass in motion. This
    reconversion proceeds at a constant rate since the big bang since the
    resolution of gravitons, their release from their shatters-clusters, proceeds
    at constant rate due to their weak specific force due to their small size.

    Graviton’s Energy-Mass Dualism:

    Gravity Is The Monotheism Of The Universe

    Everything in the dictionary and in the universe –
    nouns and verbs objects and processes – originate and derive from the
    energy-mass dualism, from the ongoing constant rate conversion of mass to
    energy, from the ongoing resolution-release of inert gravitons, mass, leaving
    the clusters of the fractured seed of the universe, singularity, and becoming
    energy, mass in motion.

    The Graviton’s energy-mass dualism derives from its
    gravity, self-attraction, and its compactness.

    Gravity:

    the propensity of the gravitons – the elementary
    particles of the mass of the universe – to return to their singularity
    state of zero motion, of compacted zero inter-particle distance.

    Compactness:

    the default particle’s size and shape that enable zero
    inter-particle distance at singularity.

    This, commonsensically, therefore possibly
    scientifically, is the matrix of the universe.

    PS:

    Life is the obvious manifestation of energy-mass dualism.
    The sun’s energy, i.e. fast-moving mass particles, convert into slow-moving
    temporary mass formats…DH
