The standard model of the Universe has it evolving from a concentrated uniform high energy density through phases of decreasing density and increasing components into the present dispersed system of galaxies. Observers use various Information channels to measure and define the parameters governing the expanding Universe. The more noise, uncertainty or error corrupting the signal the less the channel's maximum possible rate of information, the capacity. In the present era, the luminosity of galaxies is taken as the signal which is much larger than the noise of the CMBR. The standard model is applied with constituents and channel capacity examined for each main phase. Inflation occurs in the earliest Universe with constant Planck energy density and an equation of state similar to that of Dark Energy, Davies (2015). At the initial Planck time, the solution requires minimum input parameters and thus a minimum of Information is necessary. Estimates yield similar information rates from the earliest Inflation to the present era, thereby implying conservation of Information Capacity.
