Scientists like Vesto Slipher had previously noted the Doppler effects in question, but this law utilized new observations of Cepheid variable stars.
This law was developed by its eponymous scientist and his colleague Milton Humason, a former janitor at their Mount Wilson facility. It supported the ideas of Father Lemaître and helped resolve the Curtis-Shapley Debate. For decades the value of its constant, originally estimated at 500 kilometers per second per megaparsec, was uncertain, until complications like peculiar velocities were dealt with. Scientists like Vesto Slipher had previously noted the Doppler effects in question, but this law utilized new observations of Cepheid variable stars. For 10 points, name this law, a strong support for the expanding universe theory, which states that the redshift of faraway galaxies is linearly proportional to distance.
