Abstract

We present a new cosmological model, based on the holographic principle, which shares many of the virtues of inflation. The very earliest semiclassical era of the universe is dominated by a dense gas of black holes, with equation of state p = ρ. Fluctuations lead to an instability to a phase with a dilute gas of black holes, which later decays via Hawking radiation to a radiation dominated universe. The quantum fluctuations of the initial state give rise to a scale invariant spectrum of density perturbations, for a range of scales. We point out a problem, that appears to prevent the range of scales predicted by the model from coinciding with the range where such a spectrum has been observed. We speculate that this may be related to our field theoretic treatment of fluctuations in the highly holographic p = ρ background. The monopole problem is solved in a manner completely different from inflationary models, and a relic density of highly charged extremal black monopoles is predicted. We discuss the nature of the entropy and flatness problems in our model.

  • Thus, there are likely to be nearby points on the potential with small positive values and a small enough slope so that the scalars change acceptably slowly.] and no fully microscopic models of four-dimensional quantum gravity with zero or positive cosmological constant.[See [ref] for various approaches to describing $Λ> 0$ cosmology.] Even at the level of effective field theory, it is still controversial whether metastable string compactifications with $Λ> 0$ exist (see e.g. [ref] for recent discussions).

  • Describing the physics of a closed universe seems particularly challenging, since an asymptotic boundary of space appears to play a key role in the well-understood holographically-described quantum gravitational systems.[For various other approaches to describing cosmological phyics using holography, see [ref] .]
