Searching through existing data spanning 9 billion years, a team of researchers led by scientists at the University of Hawaiʻi at Manoa has uncovered the first evidence of “cosmological coupling” – a newly predicted phenomenon in Einstein’s theory of gravity, possible only when black holes are placed inside an evolving universe.
Astrophysicists Duncan Farrah and Kevin Croker led this ambitious study, combining Hawaiʻi’s expertise in galaxy evolution and gravity theory with the observation and analysis experience of researchers across nine countries to provide the first insight into what might exist inside real black holes.
