Analysis of LIGO gravitational wave data reveals a 'mass gap' in detected black holes, providing evidence for pair-instability supernovae - extremely violent stellar explosions that leave no remnant behind. This finding supports theoretical models predicting that stars above a certain mass threshold undergo complete destruction rather than forming black holes. The research represents a significant advancement in understanding stellar evolution through gravitational wave astronomy.
Background
Gravitational wave detectors like LIGO have been collecting data on black hole mergers, allowing scientists to study the mass distribution of these cosmic objects. Theoretical models had predicted that extremely massive stars might undergo complete destruction in pair-instability supernovae rather than forming black holes.
