A coming back to the steady-state cosmology permits, from the horizon radius temporal invariance, to apply the Holographic principle to Cosmology. This one invariant parameter cosmology resolves not only many problems of the standard cosmology, with its six temporally variable free parameters, but also theoretical physics problems, such as parity violation and a rehabilitation of the tachyo-bosonic string theory. In particular, this justifies the critical condition and the Universe vastness, introducing a space-time quantization, smaller than the Planck units by a factor 4.0 × 10^60, and a 'Grandcosmos' larger than the Universe in the same ratio. This Grandcosmos appears as a lacking element in the steady-state cosmology, and introduces a super-speed exceeding c in the same ratio, resolving the vacuum energy dilemma. A special form of the Eddington's horizon formula leads to a Universe mass in a specific rational ratio with the reduced electron mass, showing that the Cosmos is calculating p. Dramatic relations between cosmic and biologic canonic quantities suggests an inversion of the anthropic principle and rejection of Darwin evolution, suggesting universality of intelligent life.
