The standard cosmological model defines the Observable Universe as the region of the Universe observed from the earth at the present time; all the signals that have arrived to the earth since the beginning of the cosmological expansion. The fruitful formula of the Heisenberg uncertainty principle allow us to explore some issues concerning the observable universe. One of them is the possible topology of the universe according to recent cosmological data. The other one is the cosmological constant value, arising numerically from the Heisenberg principle. Finally will describe a numerical depiction about the evolution of the observable universe which involves the Hubble parameter, the number of stars, the hydrogen molecule, the degrees of freedom of the hydrogen mulecule related to the amount of information of ordinary matter as well as the surface area of the observable universe event horizon.
