Of the fundamental particles of matter, neutrinos are among the most elusive, though theorists postulate that these particles are plentiful in the universe. Originally thought to have no mass, neutrinos barely interact with other forms of matter, making them extremely difficult to detect.
Now, a 2-year experiment at the Los Alamos (N.M.) National Laboratory has produced evidence supporting the idea that neutrinos actually have a mass, albeit a small one. This finding has important implications for cosmology, because it allows neutrinos to account for much of the mass in the universe.
