Yes, We Can Take the Gravitational Wave Hunt to Space

Scientists at the European Space Agency have successfully engineered the quietest environment in the known universe, paving the way for deep-space gravitational wave detectors.

In December 2015, the 22-nation ESA launched the LISA Pathfinder spacecraft to determine if it’s possible for two gold-platinum cubes to remain perfectly still, relative to each other, as they orbited the sun. That meant shielding the cubes from all disturbances — even forces as minuscule as the gravitational pull
