WebDark matter appears to exist in at least two separate forms: one baryonic, and one non-baryonic. While the non-baryonic component is the dominant one, a substantial fraction of the baryons in the low-redshift Universe ( absent 1 3 –2/3; Fukugita, 2004; Fukugita & Peebles, 2004; Nicastro et al., 2005; Prochaska & Tumlinson, 2008) are also at large.
