What event is often associated with the collapse of the most extremely massive stars into a black hole via the 'collapsar' model?
Answer
Hypernova and long-duration gamma-ray bursts (GRBs)
Hypernovae are more energetic explosions linked to the collapse of very massive stars into a black hole, where the nascent black hole launches powerful jets that create observable gamma-ray bursts.
