摘 要:Theory and observations concerning the cosmic reionization epoch are briefly discussed in the context of recent observations attributed to dark matter. A case is made that cold ground state interstellar atomic hydrogen of average density of about one atom per cubic centimeter (1.67 × 10-21?kg·m-3?or 1.67 × 10-24?g·cm-3) appears to be the most likely candidate to explain these observations.Theory and observations concerning the cosmic reionization epoch are briefly discussed in the context of recent observations attributed to dark matter.
