LIGO Signals Point to Primordial Black Holes from the Big Bang
A LIGO detection involving an object lighter than a solar mass challenges standard stellar-black-hole formation, with researchers proposing a primordial black hole created in the early universe as the explanation. If confirmed, PBHs could account for dark matter, but further detections and next‑gen observatories like LISA and Cosmic Explorer are needed to build stronger evidence.
