Minuscule jitters may hint at quantum collapse mechanism

Data match prediction for wave function theory, but more experiments are needed

QUANTUM COLLAPSE  Using a miniature vibrating cantilever, scientists are searching for an explanation of how the wave function of a particle collapses to a single place. Excess jittering in the cantilever could provide clues, but other sources of shaking must first be ruled out.
