Some assumptions of holographic principle either do not match with standard model of cosmology or predict yet another consequences. This model acknowledges expansion of the Universe, observed via Hubble in 1990s and since then only more facts. Information limit of volume is measured by how much information (written into matter) can be put into volume before it becomes black hole and forcibly occupy as much volume as required to preserve area limits. But that expansion of the Universe, how does it interact with black holes?

If the space expands, that helps escaping black hole. And effective horizon of black hole should be smaller than without accounting for space expansion. And it is possible to put little more information than area permits. This is hard to verify since distances where space expansion starts being noticeable, are orders of magnitude bigger than radius of known most massive black hole. But consistent description of reality should combine them somehow.

There may be alternative solution. Area limit may turn out to be more fundamental than space expansion, and big radius black holes will have stronger gravitation to overcome space expansion.

> With gravity, mass plays the role of charge. It bends space-time around it, and it is always positive. There is no negative mass

Equations have not just mass, but also pressure, and space expansion is theoretically described by dark energy that has positive mass and negative pressure overcoming its positive mass.
