Black Holes Are Not A Source Of Dark Energy

This recent claim picked up in the mass media struck me as dubious. A new preprint explains why.
The hypothesis that the mass of BHs increases with time according to the same law as the volume of the part of the Universe containing it and therefore the population of BHs is similar to dark energy in its action was recently proposed. We demonstrate the reasons why it cannot be accepted, even if all the assumptions on which this hypothesis is based are considered true.

The objects are so massive, that if confirmed, they could change how we think of the origins of galaxies.5 days ago
