The nonlinear stage of development of a Jeans instability in a cold nondissipative gravitating gas is considered. It is shown that, for a time exceeding the Jeans time, a nondissipative gravitational singularity (NGS) is formed in the vicinity of a local density maximum. The NGS is a stationary dynamic structure based on a singularity. The density of the gas in the center of the NGS becomes infinite as r approaches zero. The turbulent state arises as a result of the development of instability in the case of an irregular initial density distribution.
