Maximum information universe.
Abstract
The Universe is considered as a photon information channel. The signal is due to galaxies while noise is taken as blackbody thermal radiation. The galaxies are allowed timedependent luminosities. The effect of Universe expansion on the information capacity of such channels is investigated. A variational approach is used yielding the time dependence of the cosmic scalefactor when the information transmitted to a perfect observer is a maximum. A capacity which is constant and independent of the spacetime location of the observer can be considered a Perfect Cosmological Principle. When the observed Deceleration Parameter is taken as 0, 1, 2, the corresponding maximum information universe is an exponential, Page and Milne universe respectively.
