EXCERPT: For years physicists have been looking for the universe's elusive dark matter, but so far no one has seen any trace of it. Maybe we are looking in the wrong place? [...] In a new research paper, he [Chris Kouvaris] and [Ian] Shoemaker study the possibility that dark matter can indeed interact substantially with atoms. They claim that depending on the properties of the dark matter particles, deep placed detectors can be blind because particles might have lost most of their energy before reaching the detector.
"In such a case, it would make more sense to look for dark matter signals on the surface of the Earth or in shallow sites", Kouvaris argues....
