"Dark Matter: The Cosmic Key to Unraveling the Mystery of Magnetic Fields"

Researchers at SISSA theorize that dark matter mini-halos could be indicators of primordial magnetic fields, potentially solving the mystery of the origin of cosmic magnetic fields. These mini-halos, resulting from the gravitational effects of primordial magnetic fields on dark matter density perturbations, could provide evidence that magnetic fields were formed within a second of the Big Bang. The study, published in Physical Review Letters, suggests that detecting these dark matter mini-halos would support the idea that magnetic fields are a primordial phenomenon, offering new insights into the early universe.
