The Parameters of the Universe

Part of the Astronomers’ Universe Series book series (ASTRONOM)


A parameter is a quantity that can take on one or more values. A child’s height or weight could be one of its parameters. Several of the parameters that occur in a cosmological context are time varying, in analogy to a child’s height or weight. The large-scale time behavior of our Universe is characterized by the parameters that determine its scale factor. They are not only measurable but over time have been evaluated with increasing accuracy. Examples are the Hubble constant H0 and the cosmological constant.
