Echoes of the Void: The Expanding Gravitational Wave Catalog
from Intellectually Curious · host Mike Breault
In this deep dive, we explore GWTC-4, the latest gravitational-wave transient catalog from LIGO, Virgo, and KAGRA. We examine how a nine-month run added 128 new candidates—more than doubling the catalog—and spotlight cosmic extremes: black holes around 130 solar masses, spins near 0.4c, and highly asymmetric pairs that challenge formation models. We unpack how standard sirens help measure the Hubble constant and what this expanding census reveals about gravity, relativity, and the hidden population of black holes shaping our universe.Note: This podcast was AI-generated, and sometimes AI can make mistakes.
