Question:
After what happened on Jupiter, if that string of rocks and gas was coming toward Earth could we destroy it with a laser? If so what kind?



Replies:
That is a good question. We do not yet have any lasers powerful enough to destroy or deflect a large meteor, asteroid, or comet. Some scientists think we might be able to use nuclear weapons to deflect an object on a collision course with the Earth if we detect the object early enough. The real problem is detecting the object: even a large meteor is very, very small compared to a moon or planet, and space (as they say) is a very big place.
