.....I guess we are trying to blow up comets...never heard of that before...
Yes, I have heard about this- I think it was on the National Geographic channel, but
it was about blowing up Meteorites! Not comets. The meteorites of course can do great damage to the earth and by blowing them up (when they come to close) they can be made smaller.
The Americans are indeed busy with the developments of missiles that can be directed towards an approaching meteorite, something like that.
that is all I heard.
