New research suggests that we may be vastly underestimating the number of black holes that existed in the early universe, which could help answer a big question in cosmology. As detailed in a study published in The Astrophysical Journal Letters,

Recent observations, including those from the Hubble Space Telescope, suggest that early galaxies harbored significantly more black holes than previously thought, challenging our understanding of their rapid growth given the limited time after the Big Bang.

The extent of job losses needed to address a £30m black hole in its budget is not yet clear, Cardiff University's vice-chancellor has said. A voluntary redundancy scheme at Wales' biggest university closed last month but Prof Wendy Larner said she did not have definite numbers of post closures and did not rule out compulsory job losses.

Stephen Hawking, Roger Penrose, Robert Oppenheimer, Karl Schwarzschild, John Wheeler, Albert Einstein, Leonard Susskind – these renowned scientists all, in one way or another, helped black holes
