Gravitational Wave Search Finds Tantalizing New Clue – Space Ref

Pairs of black holes billions of times more massive than the Sun may be circling one another, generating ripples in space itself.
The North American Nanohertz Observatory for Gravitational Waves (NANOGrav) has spent more than a decade using ground-based radio telescopes to look for evidence of these space-time ripples created by behemoth black holes. This week, the project announced the detection of a signal that may be attributable to gravitational waves, though members aren’t quite ready to claim…
