The particle’s most precise measurement yet suggests the LHC isn’t large enough

Spacetime ripples from black holes are becoming routine.

A team of physicists has used data from GPS satellites to hunt for dark matter, the mysterious stuff whose gravity appears to hold galaxies together. They found no signs of a hypothetical type of dark matter, which consists of flaws in the fabric of space called topological defects, but they say they have vastly narrowed the characteristics for how the defects—if they exist—would interact with ordinary matter. Their findings show how surprisingly innovative—and, in this case, cheap—methods might be used to test new ideas of what dark matter might be.
