#:The first 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. The second cited article, from National Geographic, November 6, 2014, is about whether an object speeding past Sagittarius A* is a star or merely a gas cloud, concluding that it is a star. No scientist doubts that the thing that this object is speeding past, Sagittarius A*, is a black hole. | #:The first cited article says absolutely nothing about the ''number'' of black holes, modeled or observed.
