New research by Professor Enrique Gaztanaga of the University of Portsmouth and the Institute of Space Sciences in Barcelona suggests that some black holes formed before the Big Bang and survived the cosmic ‘bounce’, potentially explaining dark matter, the gravitational wave background, and the early growth of supermassive black holes and galaxies. Gaztanaga proposes a … Read more
Gravity is so strange that cosmologists are essentially forced to agree on one of two equally radical conclusions: either dark matter exists or the fundamental rules of gravity require major modifications. To settle the debate, scientists embarked on the largest-ever study of gravity and discovered that old physics wisdom is powerful when it comes to … Read more

Collapse of dark matter may be the missing ingredient in explaining how supermassive black holes formed before the first stars. A growing mystery in astronomy is the existence of massive black holes (some as heavy as a billion suns) that … Read more
