Scientific research into dark matter origins

Overview

Scientific research into the nature of dark matter has expanded from investigating primordial black holes to exploring ancient stars and potential new cosmic forces.

Initial studies from the University of Portsmouth proposed that black holes formed before the Big Bang might have survived a ‘cosmic bounce,’ acting as ‘cosmic fossils’ that could explain dark matter. This research utilizes ‘bouncing cosmology’ models to address unanswered questions regarding the composition of dark matter and the origins of the universe.

Subsequent investigations have shifted focus toward the existence of ancient dark matter stars. These celestial bodies may have been powered by the self-annihilation of dark matter particles rather than nuclear fusion. Additionally, researchers are examining whether dark matter involves an unknown force beyond gravity, which could influence how dark matter halos cluster and affect the evolution of large-scale cosmic structures.
