Abstract: In efforts to demonstrate the linear Hubble law v = Hr from galaxy observations, the underlying simplicity is often obscured by complexities arising from magnitude-limited data. In this Letter, we point out a simple but previously unremarked fact: the shapes and orientations of structures in redshift space contain in themselves independent information about the cosmological redshift-distance relation. The orientations of the voids in the CfA slice support the Hubble law, giving a redshift-distance power index p =0.83±0.36 (void data from Slezak, de Lapparent, & Bijoui) or p =0.99±0.38 (void data from Malik & Subramanian).
