Origin of the Hubble constant controversy

Abstract

The long-standing argument as to whether the Hubble constant is closer to 50 or 100 km s-1 Mpc-1 may be due to large local disturbances in galactic motions caused by excess mass in the Coma-Sculptor cloud. Outside this region, a value of 85 to 95 km s-1 Mpc-1 is consistently found. © 1988 Nature Publishing Group.
