science ☄️ Nuclear weapons to defend Earth from space rocks?
Scientists tested if a nuclear weapon could protect Earth from a dangerous asteroid using computer simulations. A team from Lawrence Livermore National Laboratory studied a 160-metre-wide asteroid with a 1-megaton weapon. Researchers found explosions several metres away could vaporize material via X-rays, changing the asteroid's path. In one simulation, 98.2 per cent of the material was badly damaged when the blast was 10 metres away. These findings offer insight into nuclear disruption as a last-resort option for planetary defence. ☄️
