Watch a 16-minute conference talk examining whether current theoretical models are overestimating the rate of binary black hole mergers detected through gravitational waves. Explore how recent gravitational wave detections, Gaia's discovery of dormant black holes in detached binaries, microlensing observations of isolated black holes, and time domain surveys are revealing new populations that challenge our understanding of stellar mass black holes. Learn about the complex lifecycle of stellar black holes, from their massive star progenitors through core collapse and associated transients, to their existence as dormant or accreting objects, and their potential fate as gravitational wave sources during mergers. Discover how these emerging observational findings are compelling researchers to reassess theoretical models and develop new strategies for understanding black hole evolution and merger rates.
