A pair of studies suggest that missing galaxy mass has been found using gravitational lensing, potentially solving a conundrum that exotic physics sought to resolve. The studies found that the galaxies may have more mass than previously thought. Researchers used information gleaned from the European Space Agency's Planck probe, which initially found the discrepancy in the mass, as well as the gravitational lensing technique, which measures clusters' weight based on how light is distorted when passing through their gravitational fields. One of the studies is still in preparation; the other has been posted on the arXiv preprint server.
