Ureka! Easily and safely divert or even vaporize any size giant asteroid?
Eureka! How to easily and safely divert and even vaporize any size giant asteroid?
Gently land a nuclear reactor core on the side of the asteroid you want it to move away from. Withdraw control rods and allow the reactor to melt down. As the core evaporates everything below the shaft it is boring the gaseous rock will shoot out the top: moving the asteroid in the opposite direction with equal force.
An asteroid of the size that supposedly wiped out the dinosaurs has a gravity is about 1/600 of earth's. (Such an asteroid would be about the size of Mt. Everest. The pull is seemingly out of proportion to the mass of the earth because the surface is so much closer to the center -- the gravity does not have a chance to "spread out.")
When the core reaches gravitational center it will continue to evaporate rock all around it which could conceivably keep sinking into the superheated core instead of the other way around. If the size of the reactor core relative to the size of the asteroid were sufficient it might be possible for one or many superheated cores to evaporate an entire asteroid if the core or cores don't run out of fuel before the asteroid runs out of rock -- sort of like a reverse black hole.
