A Blue Flash in Ice
So in a sense while we are still looking to the April 3 Announcement from Cern, I thought I would lay out some information that had me stop to think and ponder about. If you ask me how this is all connected all you would have to do is surmise that my attention while directed to CERN, is also directed to the cosmological outlay of our universe.
So many experiments are connected, that while we do not see it's significance in the experiments isolation, it is part of a much bigger plan to ask what it is, is at the basis of our progression and predictions about the causes of the universe.
- Clues to the nature of dark matter could come from evidence that high-energy neutrinos are produced in the Sun. The neutrinos, according to certain dark matter theories, would result from particles called WIMPs (weakly interacting massive particles) becoming trapped by the Sun’s gravitational field and annihilating with each other. Now, the collaboration running the world’s largest neutrino telescope, the IceCube experiment at the South Pole, reports in Physical Review Letters its most comprehensive search to date for the predicted neutrinos. See: Synopsis: A Year-Long Search for Dark Matter
- We have performed a search for muon neutrinos from dark matter annihilation in the center of the Sun with the 79-string configuration of the IceCube neutrino telescope. For the first time, the DeepCore subarray is included in the analysis, lowering the energy threshold and extending the search to the austral summer. The 317 days of data collected between June 2010 and May 2011 are consistent with the expected background from atmospheric muons and neutrinos. Upper limits are set on the dark matter annihilation rate, with conversions to limits on spin-dependent and spin-independent scattering cross sections of weakly interacting massive particles (WIMPs) on protons, for WIMP masses in the range 20–5000 GeV/c2. These are the most stringent spin-dependent WIMP-proton cross section limits to date above 35 GeV/c2 for most WIMP models.See: Search for Dark Matter Annihilations in the Sun with the 79-String IceCube Detector

| The ATLAS Experiment offers the exciting possibility to study them in
the lab (if they exist). The simulated collision event shown is viewed
along the beampipe. The event is one in which a microscopic-black-hole
was produced in the collision of two protons (not shown). The
microscopic-black-hole decayed immediately into many particles. The
colors of the tracks show different types of particles emerging from the
collision (at the center). Photo #: black-hole-event-wide |
A message from the Past perhaps?
 | Exploring the Wonders of the UniverseThe newly-installed Alpha Magnetic Spectrometer-2 is visible at center of the International Space Station's starboard truss. The Alpha Magnetic Spectrometer, or AMS, is the largest scientific collaboration to use the orbital laboratory. This investigation is sponsored by the U.S. Department of Energy and made possible by funding from 16 nations. Led by Nobel Laureate Samuel Ting, more than 600 physicists from around the globe will be able to participate in the data generated from this particle physics detector. The mission of the AMS is, in part, to seek answers to the mysteries of antimatter, dark matter and cosmic ray propagation in the universe. Image Credit: NASA |
