超新星爆炸的能量来源

按照nasa的说法，重力造成的塌陷反弹。
“Gravity gives the supernova its energy. For Type II supernovae, mass flows into the core by the continued formation of iron from nuclear fusion. Once the core has gained so much mass that it cannot withstand its own weight, the core implodes. This implosion can usually be brought to a halt by neutrons, the only things in nature that can stop such a gravitational collapse. Even neutrons sometimes fail depending on the mass of the star's core. When the collapse is abruptly stopped by the neutrons, matter bounces off the hard iron core, thus turning the implosion into an explosion.”
按照真理社的说法。重力压缩使得电子进入简并态，被挤压进质子形成中子，这个过程中释放出1E58数量级的中微子。这些25%光速的中微子被压缩过的铁核aka中子核捕获，形成了爆炸的压力能量来源
本民科觉得真理社的解释靠谱一些
