Primordial black holes may have triggered Type Ia supernovae — and could be detected

New research suggests that primordial black holes (PBHs), hypothetical objects formed from dense matter in the early Universe rather than from stars, could penetrate white dwarfs and trigger Type Ia supernovae. These events would leave distinctive chemical signatures detectable by astronomers. The finding offers a potential new method for indirectly confirming the existence of PBHs.

Should indirect evidence be enough to confirm the existence of primordial black holes?
