chuck4 said:Yeah, right. When just a single new vapor jet can double the brightness of a comet, nobody saw the enormous brightening that would accompany the massive burst of water and other volatile vapor that would accompany the sudden exposure of all that fresh ice to sunlight as a comet breaks apart near the earth.

Triton said:For how long would a huge heavy-lift booster with nuclear warhead(s) be operational to destroy the extinction-level event comet? 20 years? 30 years? When would the engines need to be refurbished and the booster refueled?
the world did not end in 1883. A new paper reinterpreting old astronomical data argues that a massive comet disintegrated near Earth and its fragments passed as close as 600km from us in August of that year.

August 1883 ? definitively a bad month then, since the Sunda Straits Krakatoa volcano exploded that very month - killing 36000 people in an explosion so huge it was heard 2500 miles away. Imagine if the comet strikes added to that mess...
