![]() ![]() Game changing resultsĭr Duncan Farrah, University of Hawai’i Astronomer and lead author on the study, said: This data provided a crucial steppingstone to understanding the distant universe and then dead galaxies and black holes. STFC RAL Space led efforts to accumulate data from massive galaxies in the local Universe, and particularly ultra-luminous infrared galaxies linked to previous work conducted by RAL Space using the Herschel Space Observatory. It was led by the University of Hawai’i, including Imperial College London and STFC RAL Space. The study, which is published in The Astrophysical Journal and The Astrophysical Journal Letters, was conducted by a team of 17 researchers in 9 countries. This new result suggests that black holes could account for the total amount of dark energy responsible for the accelerated expansion of the Universe. ![]() It also shows that black holes gain mass in a way consistent with them containing vacuum energy, providing a potential source of dark energy. To test this theory, researchers took measurements from ancient and dormant galaxies to show that black holes are growing more than traditional explanations account for. For example, produced by the production and destruction of virtual particles and antiparticles in a perpetual cycle, which pushes the Universe further apart despite this strong gravitational pull. One explanation for this could be that black holes are a source of dark energy in the form of vacuum energy. However, this theory is challenged by our understanding of black holes, which have an extremely strong gravitational pull that is hard to oppose, especially at their centres. Answering fundamental questionsĭark energy is thought to be the reason that the Universe expands faster as it ages even though the pull of gravity between objects should be slowing the expansion down. If confirmed, this finding has the potential to change our understanding of black holes as well as providing an origin for the dark energy in the Universe. The study, which included contributions from physicists at the Science and Technology Facilities Council (STFC) RAL Space, contains the first observational evidence that dark energy connects black holes to the expansion of the Universe.
