The Search for Dark Matter Continues (Scientific American)

outer space, galaxy, universe, Dark matter: invisible and untouchable, yet a prominent gravitational force tugging on the Universe’s normal matter. With recent funding, three projects now move forward to attempt to identify the particles behind these gravitational forces. They differ in the types of detectors they will use to search for particles that currently only exist in theory (WIMPs and axions). These labs are confident that they will be able to either detect particles or reject their hypothesis within this next stage of research.

“In science the ruling out is as important as discovery,” says Stanford University physicist Blas Cabrera, “but of course discovery is always more fun.”

Cabrera, a spokesperson for the CDMS collaboration, also presented a Kibbe lecture at Bowdoin this past spring.
