erm.. money going into shooting down asteroids in stead of war?
hmmz.. u havent been on the happy grass, now have u?
Asteroids and meteors constantly go into our atmosphere. But the thing is that most of them are not large enough to make it through, since practically all of them get burned on the way down.
The chances of one actually making it down to earth and still be large enough to cause large scale damage is quite slim.
So its not really something to be worrying about.
btw: an asteroid the size of a football that hits the earth could probably wipe out a city/country. But I dont think many could last that long and still stay that size. plus there is a slim chance that one that big will head towards us.
And maybe putting some money into preventing them is good. but not putting money into war might not be a good idea either.
