  Cosmic Microwave Map Swirls Indicate Inflation 

  Explanation: Did the universe undergo an early epoch of extremely
  rapid expansion? Such an inflationary epoch has been postulated to
  explain several puzzling cosmic attributes such as why our
  universe looks similar in opposite directions. March 16, results
  were released showing an expected signal of unexpected strength,
  bolstering a prediction of inflation that specific patterns of
  polarization should exist in cosmic microwave background radiation
  -- light emitted 13.8 billion years ago as the universe first
  became transparent. Called B-mode polarizations, these early
  swirling patterns can be directly attributed to squeeze and
  stretch effects that gravitational radiation has on
  photon-emitting electrons. 

  The surprising results were discovered in data from the Background
  Imaging of Cosmic Extragalactic Polarization 2 (BICEP2) microwave
  observatory near the South Pole. BICEP2 is the building-mounted
  dish pictured above on the left. Note how the black polarization
  vectors appear to swirl around the colored temperature peaks on
  the inset microwave sky map. Although statistically compelling,
  the conclusions will likely remain controversial while
  confirmation attempts are made with independent observations.
