Scientific paper

We discuss work in progress about the existence and possible forms of molecular hydrogen as a dark matter component particularly in the outer galactic disks, and in late or low surface brightness galaxies. Mainly, the direct condensation of molecular hydrogen in solid or liquid form during gravitational collapses opens possibilities on the evolution of collapsing cold gas in the interstellar medium that differs from star or planet formation. Gas globules stabilized in their centre by a terrestrial planet-sized liquid or solid core of molecular hydrogen are possible long-lived structures that naturally explain a series of apparently distinct problems, such as the cometary globules in planetary nebulae and the relation of HI to dark matter in galactic disks.
