Most scientists believe the strange material is made of an undiscovered particle that doesn’t absorb or reflect normal light.<\/p>\n
But a new theory\u00a0suggests that dark matter might really be made of ancient black holes that existed before the Big Bang.<\/p>\n
These ‘relic’ black holes from another universe are small, packed with mass, and would be totally invisible except for their gravitational tug.<\/p>\n
According to Professor Enrique Gaztanaga, from the University of Portsmouth, this makes them the prime suspect in the search for dark matter.<\/p>\n
The key to this bold suggestion is the suggestion that there was a universe before our current one, and the Big Bang was just the transition between the two.<\/p>\n
Professor Gaztanaga says: ‘The idea is that dark matter may not be a new particle, but instead a population of black holes formed in a previous collapsing phase and bounce of the Universe.’<\/p>\n

The mysterious substance known as dark matter could really be made up of black holes from another universe, according to a scientist\u00a0<\/p>\n
According to the most common theory, the universe began as an infinitely dense point known as a ‘singularity’.<\/p>\n
This singularity then exploded out in a rapid phase of expansion known as inflation, the lingering energy from which we can still see as the Cosmic Microwave Background.<\/p>\n
However, some scientists don’t like the idea of a singularity because their infinitely dense interiors appear to break down the fundamental rules of physics as we know them.<\/p>\n
To get around this issue, Professor Gaztanaga suggests we might live in a ‘bouncing’ universe.<\/a><\/p>\n According to this view, the universe collapsed in on itself<\/a>\u00a0at the end of its previous phase, falling inwards to an enormously, but not infinitely, dense point.<\/p>\n As the universe became more and more dense, it eventually hit a point where it ‘bounced’, rushing outwards in a period of inflation to form the universe we currently live in.<\/p>\n ‘The Big Bang corresponds to a bounce from a previous collapsing phase, rather than the absolute beginning of everything,’ Professor Gaztanaga told the Daily Mail.<\/p>\n ‘So it is the start of the expansion we observe, but not necessarily the beginning of time itself.’<\/p>\n According to this theory, the Big Bang was not the start of the universe but simply a transition from a previous universe’s collapse to our current one. Black holes from the earlier might have survived this transition and now make up dark matter\u00a0<\/p>\n What makes this idea so important for dark matter is that Professor Gaztanaga says that black holes might have survived the collapse.<\/p>\n That means the black holes formed by the collapsing galaxies of the last universe could still be floating around our universe today.<\/p>\n Professor Gaztanaga says: ‘These ‘relic’ black holes would survive into the expanding phase we observe today and behave exactly like dark matter: they interact gravitationally, but do not emit light.’<\/p>\n Although this sounds far\u2013fetched, it actually helps avoid some thorny problems plaguing our current theory.<\/p>\n Scientists neither need to explain away the infinite density of the singularity nor add any mysterious extra particle to explain dark matter.<\/p>\n Likewise, the relic black hole theory could help explain some of the most puzzling discoveries made by the James Webb Space Telescope (JWST).<\/p>\n![\"According](\"https:\/\/www.newsbeep.com\/uk\/wp-content\/uploads\/2026\/04\/107908203-15734741-image-a-5_1776242859070.jpg\")
