A Potential Astrophysical Source of Dark Energy.
This article is a scientific study about the relationship between black holes and the universe's expansion, and how this might be linked to dark energy, a mysterious force that's believed to be causing the universe to expand at an accelerating rate.
The authors start by discussing the evidence they've found for black holes of various sizes throughout the universe's history. They note that the current model for black holes, known as the Kerr solution, doesn't quite fit with the idea of an expanding universe. Instead, they propose that black holes might actually grow in mass as the universe expands, not just from sucking in matter or merging with other black holes, but in a way that depends on what's happening inside the black hole.
