The “rockburst” is the sudden release of the stress potential energy formed by the expansion of atoms in solid objects caused by the cosmic expansion. According to the “rockburst plus nuclear explosion” model, the “rockburst” was firstly triggered by the heat produced by the friction between the asteroid and the atmosphere after it entered the atmosphere, and then the high temperature and high pressure generated by the “rockburst” ignited the fusion fuel inside the asteroid, resulting in a thermonuclear explosion.展开更多
