Black Hole Mergers Illuminate Stellar Evolution

Recent analysis of black hole mergers reveals a significant "mass gap" in the detected population of black holes. This discovery suggests that some stars possess such massive cores that they culminate in a pair-instability supernova, resulting in total annihilation rather than forming a black hole or neutron star.

Black holes emerge from the core collapse of stars during supernova events. While the outer layers explode outward, the core may plunge inward, contributing to the formation of a black hole. As researchers continue to analyze data from gravitational wave detectors, our understanding of stellar evolution and the life cycles of these massive celestial bodies is becoming increasingly clear.
