Abstract

We adopt a new result in non-equilibrium statistical mechanics to follow the time evolution of the density of an exploding one-dimensional gravitational gas. We show analytically that the resulting structure formation is a natural consequence of many-body physics.

Key words: instabilities – galaxies: formation – large-scale structure of Universe
