Early data from a Columbia-led dark matter experiment rule out recent hints by other scientists who say they have found the elusive particle that holds the universe together. The findings show that dark matter, which is believed to make up 83 percent of the matter in the universe, is more elusive than many had hoped.
"Dark matter particles continue to escape our instruments, yet we are getting much more clever in our search and feel confident that we will soon unveil them," said Elena Aprile, spokesperson of the XENON100 experiment and a professor of physics at Columbia University.
Aprile and her collaborators, who number more than three dozen physicists at nine institutions around the world, presented their findings at a dark matter workshop on May 1 and have submitted a paper to the journal Physical Review Letters. The scientists, whose experiment is the most sensitive search for dark matter to date, plan to release a much larger set of data over this summer.
The group did not expect to find dark matter in this short run of data taken last fall. Instead, their results show that the detector is better than any other at screening out background radiation that can be mistaken for the elusive particles.

I think dark matter is just scientists code for 'we don't know what 90% of the universe is."
