- Without dark matter, galaxies would lose a large fraction of the gas that forms new stars immediate after the first major star-forming event they experienced. Gas could still funnel into them from minor mergers and the surrounding intergalactic medium, but they would possess much less of the material that forms new stars than modern galaxies do.
