Hubble's Law
Concerning the graph in this article: the redshift, being a dimensionless quantity, should not be expressed in units of km/s. What is meant is the 'recession speed', which is equal to the redshift times the light velocity. It is not correct to express a redshift in km/s! Moreover, the title of the article ("Hubble's Law") should be changed into "Hubble-Lemaître Law".
