The Hubble Constant
by Neal Jackson
Publisher: arXiv 2014
Number of pages: 48
Description:
The author reviews the current state of determinations of the Hubble constant, which gives the length scale of the Universe by relating the expansion velocity of objects to their distance. Many, but not all, object-based measurements give H0 values of around 72-74km/s/Mpc.
