Gravitational collapse requires great densities. In the current epoch of the universe these high densities are only found in stars, but in the early universe shortly after the [[big bang]] densities were much greater, possibly allowing for the creation of black holes. The high density alone is not enough to allow the formation of black holes since a uniform mass distribution will not allow the mass to bunch up. In order for [[primordial black holes]] to formprighghfhhhh in such a dense medium, there must be initial density perturbations which can then grow under their own gravity. Different models for the early universe vary widely in their predictions of the size of these perturbations. Various models predict the creation of black holes, ranging from a [[Planck mass]] to hundreds of thousands of solar masses.<ref>{{cite arXiv |eprint=astro-ph/0511743v1 |last1=Carr | first1=B. J. |title=Primordial Black Holes: Do They Exist and Are They Useful? |class=astro-ph |year=2005}}</ref> Primordial black holes could thus account for the creation of any type of black hole.
