Most of the energy during the collapse of the iron core of a supergiant star is released in the form of neutrinos-nearly massless subatomic particles that rarely interact with matter.So how is it they can blow away a stars outer shells?
A)Although they rarely interact with matter,the sheer number released during the collapse is enough to move most of the star's mass into surrounding space at incredibly high rates of speed.
B)By creating a massive magnetic field that convulses in on itself,ripping away the stars outer shells
C)When neutrinos exceed a certain speed,22,300 km/s,they interact with matter quite effectively.
D)By developing a temporary,but relatively strong positive charge

Although neutrinos rarely interact with matter, the sheer number of them released during the collapse of the iron core is enormous. This means that they can push the outer shells of the star away at incredibly high rates of speed, resulting in a supernova explosion.
