Was Bruce Willis right? Could a nuclear blast save us from killer asteroid?
Briefly

In a groundbreaking study, researchers at Sandia National Laboratories simulated a nuclear X-ray pulse to effectively alter an asteroid's trajectory, mimicking potential real-world applications for asteroid deflection.
Dr. Nathan Moore explains, "The pulse created a vapor plume which pushed the rock away. The vaporized material shoots off one side, pushing the asteroid in the opposite direction." This demonstrates practical methods for asteroid deflection.
Using the powerful Z machine, scientists generated X-ray pulses by creating plasma, effectively simulating a nuclear detonation in a controlled environment, providing new strategies for planetary defense.
Moore noted that concentrating immense power—about 80 trillion watts—overcomes the energy needed for this simulation, which could lead to effective behavior modification of dangerous asteroids before they approach Earth.
