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 star's outer shells?
A. by developing a temporary, but relatively strong positive charge B. 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. C. by creating a massive magnetic field that convulses in on itself, ripping away the stars outer shells D. When neutrinos exceed a certain speed, 22,300 km/s, they interact with matter quite effectively.
