was to close to our atmosphere, what type of effect would that have on the earths atmosphere, would there be a fallout?
Firing an ICBM ant an asteroid coming towards us at, lets say, 40K mph is not going to have any affect whatso ever on the asteroid. If nuclear weopons
are used in this manner to stop killer asteroids, then they must be parked in geo-sync orbits.
Nuclear detonation in the upper atmosphere will have little detrimental affects on the world. But still, trying to stop an asteroid in the atsmosphere
with a nuclear weapon is like trying to stop a car speeding towards you with a 20lb sledgehammer. It won't slow an asteroid, the size of Toutatis,
down or change it's trajectory one bit. In the event that astronomers do find an asteroid headed for an impact with Earth, we haven't got anything
in place to stop this cataclysmic event from happening. We're just lucky that Toutatis missed us by a million miles, or we'd be seeing spectacular
sunsets like we've never seen, and drops in temperatures worldwide that would affect the world's food supply.
Back to the topic of the thread. We need nuclear weapons as deterant. It's just sad now that so many countries, that aren't exactly stable IMO, has
nuclear capability.
I must agree that nuclear weapons, like conventional weapons, has the potential to kill many innocent people. It would be nice to think that we could
live in an Utopia-like world, but sadly, there are elements that will not permit that to happen.
