• Because of the upper limit of the nuclear density , which prevents the core to compress too far , the collapsing inner core will bounce back outwards . this out - going inner core will collide with the in - coming outer core , which is collapsing rapidly . this collision will send off shock waves and create heavy elements , like uranium
  由于原子核的天然密度会成为巨大的阻力，防止核心进一步收缩，这时核心会猛烈反弹，以极高速塌缩的核心外壳会和反弹中的核心碰撞，产生强烈的冲击波，同时产生出像铀等比铁更重的元素，并把恒星外壳炸毁，这便是
