The possibility of a connection like this would make astrophysicists' lives easier.

Black holes may be a source of so-called dark energy that impacts the universe's expansion, according to a group of astrophysicists from the University of Hawaii, Imperial College London, and other research organizations.

The researchers examined many supermassive black holes and found that now the elliptical galaxies have many more holes than they had 9 billion years ago. However, there are no substances due to which black holes might arise.

Supermassive black holes are thought to be generated not only by stars, interstellar dust, and other black holes, but also by the energy of the vacuum, which is absorbed by black holes.

According to new estimates, black holes have absorbed so much vacuum energy that it explains the existence of a large amount of dark energy in the universe. The Universe is more than 95 percent composed of dark matter and dark energy.

Scientists indicate that the method they proposed for the emergence of dark energy does not require that astrophysicists' assumptions about how the Universe operates be corrected.
