Neutrinos not only have mass, but they oscillate or change their identity as they travel. Scientists measured the third of three numbers that describe how these neutrinos change identity. Because this last "mixing angle" is larger than thought, it becomes possible to check whether the oscillations of neutrinos and antineutrinos differ, possibly answering the question, 'Why is there matter in the universe?'
