Tabletop-sized gravitational wave detector could shed light on dark matter

It can take huge equipment to detect the tiniest things, and that's particularly true when it comes to gravitational waves. The LIGO detector uses 4-km-long (2.5-mi) arms to pick up distortions just a thousandth of the width of a proton. But now, a Northwestern University team is aiming to build a gravitational wave detector small enough to fit on a tabletop, which could detect signals the larger facilities miss.
