#''Computer simulations based on the theory of relativity predict far more black holes than are observed''.

#:The cited article says absolutely nothing about the ''number'' of black holes, modeled or observed.  It is about a discrepancy between computer models predicting the ''masses'' of black holes at the centers of galaxies and the observed masses.  The article suggests a heretofore-unmodeled mechanism whereby galaxy evolution would cause less mass to go into the black holes.  The article in no way suggests that black holes don't exist.

#:Relativity does not predict quasars; relativity was formulated in 1905, and quasars weren't discovered until the 1950s.  The word "relativity" does not occur anywhere in the cited article.
