Primordial Black Holes May Trigger Type Ia Supernovae, Explaining Milky Way Chemical Patterns

An international research team suggests that primordial black holes (PBHs), hypothetical remnants from the early universe and potential dark matter candidates, could pass through white dwarf stars and trigger Type Ia supernova explosions. This mechanism could explain observed chemical abundance patterns in supernova remnants and stars across the Milky Way.
