The universe is filled with blackbody millimeter radiation (CMBR),temperature 2.7{\deg} Kelvin[1]. Big-bang cosmology explains this by theinitial thermalization of photons scattered by electrons[2]. This explanationrequires ad hoc previous existence of photons and thermal electrons. On theother hand most of the mass of the universe is unknown dark matter3. Itexplains anomalous dynamical properties, like that of stars in galaxies[4,5,6]. Alternatively the anomalies have been explained by adjusting and modifyingwell known laws ("Modified Newtonian dynamics"[7]). Here we show thatmillimeter black holes (m.b.h.) explain both: the background radiation, by itspartial "evaporation", and the dark matter. Black holes emit blackbodyradiation (Hawking[8] evaporation), and this is what is observed in the CMBR.Millimeter size black holes emit blackbody radiation at a temperature of2.7{\deg} Kelvin, and this is the resulting CMBR . Partial evaporation of~10^30 m.b.h. gives the observed background field of photons being emitted andabsorbed at the same rate by the m.b.h. The number of photons is constant, asobserved. Their temperature decreases with time because the mass of the m.b.h.(and therefore its size) increases with time (the mass-boom effect[9]). Thetotal mass of the m.b.h. is the dark matter. Hence dark matter is not so "dark"after all. Two important cosmological items are here identified by only onesource: millimeter black holes.
