The world’s most sensitive dark
matter detector has failed to yield any trace of the elusive substance thought
to account for more than four-fifths of the mass of the universe, even after 20
months of operation. The Large Underground Xenon (LUX) dark matter experiment,
which operates beneath a mile of rock at the Sanford Underground Research
Facility in the Black Hills of South Dakota, has completed its silent search
for the missing matter of the universe. LUX’s sensitivity far exceeded the
goals for the project, scientists said, but yielded no trace of a dark matter
particle.
