Sixty-seven million light-years away, three galaxies have been found where standard cosmology says none should exist — stripped of the dark matter that theory insists is the invisible cradle of all galactic life. The discovery of NGC 1052-DF9, the third such galaxy in a peculiar linear chain, does not unravel our understanding of the cosmos so much as deepen it: these orphaned galaxies may be the rare scars left by catastrophic collisions that tore ordinary matter free from its invisible scaffolding. In their absence of something we cannot see, they offer some of the most tangible evidence yet
