Going back to the earlier point, would nuking asteroids help? As was mentioned earlier, in a vacuum you wouldn't get the added affect of air pressure fluctuation would you? Does the same apply for the use of thermobaric weapons and 'conventional' cruise missiles or ICBM's? Although here obvious problems with range and flight patterns and angles occur...
If, per chance, an asteroid did strike Earth. Would we notice? Millions of asteroids must have impacted the earth over the billions of centuries. After all, without asteroids the earth wouldn't have had the majority of the water it does now. And in recent centuries, lumps of 'space rock' are continually colliding with the Earth. However if you are talking about an Asteroid with the magnitude and capability to change the way we live on Earth, would nuclear weapons be of any use? Or even have an affect, after all this isn't futurama...
Please would someone with more 'knowledge' or 'experience' clear some of these questions up for me?
