FERMI NATIONAL ACCELERATOR LABORATORY/ SCIENCE PHOTO LIBRARY By Leah Crane Two of the most mysterious and elusive particles in the cosmos, neutrinos and dark matter, might be tied together by a weak force that permeates galaxies and gives neutrinos mass. Most fundamental particles get their mass from the Higgs field, which permeates the entire universe like a pool of molasses, slowing down all particles that interact with it and making them heavy. But neutrinos are a million times lighter than the next lightest particle, the electron,
