@frank-germany ,
I was watching some of the programs about space and the solar system on TV (at PBS, which is the Public Broadcasting System in US) and I heard them saying that one of the major threats to earth is the possibility of a medium to big size asteroid hitting it without any warning. They (the scientists) were saying that there are two ways to deal with this threat, one is to blow up the asteroid and destroy it in space which might result in having a bunch of smaller asteroids to deal with, and the other way is to try to change the course and trajectory of the asteroid while it is still far away from earth so that it wouldn't hit earth, and in order to do this you don’t have to hit the asteroid with any missile or anything, all you have to do is to park a spaceship right next to it while it is still far enough from earth and the pull of gravity that is produced by the spaceship on the asteroid although very small, but will gradually help change the course of the asteroid by very small degree which is enough to make it miss earth without having to have to destroy it.
My suggestion to you and others is that instead of trying to destroy anyone, perhaps its better if you let the pull of the gravity of your personality and logic set them on the right course. That’s what someone did 2000 years ago, he didn’t use a sword to attack people, he only used common sense based on logic and compassion to guide them, and it was the gravity of his personality that made him an internal force for good that so many people believe in to this day.
