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] .]
