Massive Primordial Black Holes in Contemporary and Young Universe (old
  predictions and new data)
  A brief review of the recent astronomical data, indicating that the universe
is abundantly populated by heavy black holes (BH), is presented. Conventional
astrophysics and cosmology cannot explain such a high population of BHs. A
mechanism of the paper of 1963 is described, which at least qualitatively
explained the observational data. In particular, the prediction that massive
primordial BHs can be cosmological dark matter "particles" is discussed.
