@article{Zhang2010ConstraintsOT, title={Constraints on the Dark Side of the Universe and Observational Hubble Parameter Data}, author={Tong-Jie Zhang and Cong Ma and Tian Lan Department of Astronomy and Beijing Normal University and Center for High Energy Physics and Peking University}, journal={Advances in Astronomy}, year={2010}, volume={2010}, pages={184284} }

This paper is a review on the observational Hubble parameter data that have gained increasing attention in recent years for their illuminating power on the dark side of the universe: the dark matter, dark energy, and the dark age. Currently, there are two major methods of independent observational measurement, which we summarize as the “differential age method” and the “radial BAO size method.” Starting with fundamental cosmological notions such as the spacetime coordinates in an expanding… Expand
