Mini-detectors for the gigantic? Bose-Einstein condensates are currently not able to detect gravitational waves

The gravitational waves created by black holes or neutron stars in the depths of space have been found to reach Earth. Their effects, however, are so small that they can only be observed using kilometer-long measurement facilities. ...
