For the first time in human history, the question is no longer whether we could survive an asteroid impact, but how precisely we might prevent one. Researchers at the China Academy of Launch Vehicle Technology have proposed a two-stage planetary defense method — drilling a cavity into an asteroid before detonating a nuclear device subsurface — that simulations suggest could triple the deflective force of a surface explosion. The proposal reflects a quiet but profound shift in humanity's relationship with cosmic fate: from passive acceptance to deliberate, engineered resistance.
