density parameter

density parameter

Symbol: ω. A key parameter in determining the fate of the Universe. It is defined as the ratio of the actual density of matter in the Universe to the critical density, where the critical density is the density of matter above which an expanding Universe will eventually recollapse. It is currently thought that the value of ω is about 0.3. Before 1980 it was one of the mysteries of cosmology as to why the value of ω is fairly close to 1. The theory of inflation provides an explanation of why this is the case.

Even if we give the right density parameter values, it will not be able to deal with different range of densities and this may vary based on the nature of data base.
However, the train of thought bypasses the vital transport sector, in which the problem of energy storage must also take into account the energy density parameter.
Another remark concerning the variances of the estimates of the component density parameter is that increasing (decreasing) the proportion of a component in the mixture reduces (increases) the variance of the estimate of the corresponding parameter.
They have determined that the microwave sky is lumpiest on scales between 12[degrees] and 1[degrees], as predicted for a flat universe (one with a cosmological density parameter 0 of exactly 1).

Those parameters range from the Hubble constant (H0), which quantifies the universe's present-day expansion rate, to the cosmological density parameter (W0), which tells how much matter and energy the universe contains.
