Dark matter could be made of black holes from a different UNIVERSE

"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."

"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."

"According to this view, the universe collapsed in on itself at the end of its previous phase, falling inwards to an enormously, but not infinitely, dense point."

Dark matter, which constitutes about 27% of the universe's mass, may be formed from ancient black holes that existed before the Big Bang. These black holes, described as 'relics', are small and invisible except for their gravitational effects. Professor Enrique Gaztanaga proposes that instead of being a new particle, dark matter could be a population of black holes from a previous universe phase. This theory suggests a 'bouncing' universe model, where the universe collapses and then expands, avoiding the issues associated with the singularity concept.
