A 7-hour gamma-ray burst is like a train that never ends. Such records break old models and point to a new scenario: a black hole falling into a helium star and detonating it from within. Perhaps this is the key to understanding the most powerful explosions and sources of gravitational waves.
🎯 The burst’s energy was so enormous that for those 7 hours, it outshone all the stars in its galaxy combined.
