Could Some Black Holes Predate Stars? | PBS Space Time

PBS Space Time examines the possibility of primordial black holes: objects that, in theory, could have formed in the early universe rather than from collapsing stars. The episode uses gravitational-wave astronomy to explain why unusual merger signals can prompt researchers to revisit ideas about how black holes originate.

The attraction is the link between a measured signal and the competing explanations built around it. A candidate event is not a confirmed population of primordial black holes, and the connection to dark matter remains a research question. Watch for what has been observed, what has been inferred and what still needs a stronger test.
