What role do neutrinos play in the outward propagation of the supernova shockwave?
Answer
They help re-energize the stalled shock.
The initial shockwave often stalls as it moves through infalling matter; the subsequent tremendous flux of neutrinos streaming from the dense core re-energizes this stalled shock, driving it outward to cause the visible explosion.
