Now there are two more options available for theoretical physicists mulling over the mystery of what dark matter is, and with them come another two pointers towards how to narrow down our search. UC Santa Cruz Professor of Physics Stefano Profumo published a paper examining whether dark matter was always there or instead could have come from a 'mirror world' or the edge of space ballooning along with the rest of the universe. Whatever its truth, it would produce dark matter that does not interact with ordinary particles and significantly modify our modern view of the cosmos. New Theories Suggest Dark Matter Emerged from a Mirror World or Cosmic Horizon Radiation As per Physical Review D reports, Profumo's July study theorises that dark matter could form in a shadow sector that mirrors known particles and forces yet remains completely undetectable. The theory is like quantum chromodynamics (QCD), but the dark sector has new quarks and gluons, and it imagines that heavy “dark...
