What is the essential mechanism credited with reviving the stalled shock wave to drive the supernova explosion?
Answer
The emission and absorption of neutrinos
The emission of neutrinos generated during the core collapse deposits just enough thermal energy into the stalled shock wave, re-energizing it and launching it outward powerfully.
