XENON100, a new widely anticipated experiment underneath a
mountain in Italy designed to detect dark matter particles, did
not see anything during a test run last fall, scientists
reported Saturday.But, they said, the clarity with which they
saw nothing spurred hopes that such experiments are approaching
the rigor and sensitivity necessary to detect the elusive
gravitational glue of the cosmos.The results also cast further
doubt on some controversial claims that dark matter has already
been seen."It's the strongest statement about dark matter today
and it reads: we have looked here and there and over there but
didn't find nothing," said Rafael Lang of Columbia University,
one of the researchers.A
paper describing the
work has been submitted to
Physical Review Letters.
