one could argue that it would require significant fine-tuning to produce an open universe with a minuscule but still observable deviation of $\Omega_{0}$ from $1$, e.g. $1-\Omega_{0} \sim 10^{-2} - 10^{{-3}}$. However, this conclusion is not necessarily correct. Freivogel et al. argued that long stage of inflation in string theory may be improbable, so it would be natural to have $\Omega_{0} \ll 1$ [@Freivogel:2005vv]. The only reason why we do not live in such a universe is that the formation of galaxies would be disrupted by expansion of a curvature dominated open universe, just as it is disrupted by the existence of a cosmological constant [@Weinberg:1987dv]. This provides a possible anthropic explanation of the smallness of the parameter $1-\Omega_{0}$. According to [@Freivogel:2005vv], the probability of observing the deviation from flatness $1-\Omega_{0}<0.02$ is about $90\%$. This result was further strengthened in [@DeSimone:2009dq], where it was shown that in a certain class of the probability measures, the probability of finding a universe with $1-\Omega_{0} > 10^{-3}$ is only about 6%. One should bear in mind that such estimates strongly depend on the choice of the probability measure, which remains an unsolved problem. However, these estimates suggest that one can obtain an explanation
