Although the perspective for nearby objects in the hyperbolic space is very nearly identical to Euclidean space (i.e. the Universe locally is approximately flat consistent with local observations), the apparent angular size of distant objects falls off much more rapidly, in fact exponentially. The Universe globally is hyperbolic as we did prove mathematically. The current observed density of the Universe =1031g/cm3 is consistent with a hyperbolic open universe. The hyperbolic universe consists of zero cosmological constant. The hyperbolic universe doesn`t need Dark Energy to account for the accelerated expansion. The Hyperbolic Universe grows exponentially preserves a legitimate inflation covers the current observed large structure 1.3x1028cm. The equation of state of cosmologyp=-ρ is a property of the hyperbolic structure of the hyperbolic universe. We calculated the Hubble constant due to the Hyperbolic Universe, H=72.34 [(Km/sec)/Mpc].
