We Thought All Black Holes Came From Stars. We May Have Been Wrong.
Season 11
Episode 33
LIGO may have detected a black hole that shouldn't exist, potentially revealing the first evidence of primordial black holes formed in the earliest moments after the Big Bang. But the bigger story is how a decade of gravitational-wave astronomy has transformed from proving Einstein right into a mature science capable of uncovering entirely new physics.
