flatness problem

[′flat·nəs ‚präb·ləm]
(astronomy)
The problem of explaining why, after 1010 years of expansion, the density parameter is of the order of 1, whereas the standard big-bang theory suggests that once this parameter deviates even slightly from 1 it very quickly approaches an asymptotic value far away from 1 for open or closed universes.
