Well, if you're a conspiracy buff, then you've probably heard of Majestic 12. Their secret documents say that aliens are planning a worldwide invasion, with the purpose of exterminating the human species on the year 2030. A lot to look forward too!
Well, after that asteroid in 2017 we're all dead anyway so who cares
If aliens had found a way to travel faster than the speed of light don't you think they'd have the technology to drop a few nukes in our atmosphere? That would be all that was needed. No messy invasion.
Or a few asteroids. Less messy, no fallout to clean up afterwards etc. (and you don't have to take your bombs with you, there's plenty of them right here in this solar system).
Nothing to fear, according to an article I read in this forum a few months ago, we're going to die in 2006 due to some plague or something.
Probably a conspiracy between the alien invaders and the CIA to take over the world
Don't mean to pick nits here, but he is right about the breaking up. The smaller bits present more surface area as the enter the atmosphere, and more mass will burn off as it enters the atmosphere, and less mass will strike the actual surface.
Depends on how small the bits are. If each bit is still larger than the asteroid that caused the Tunguska event, we could be worse off with many smaller hits than one biggy.
As with bombs, many small strikes are worse than a single huge strike. More dirt and water vapour thrown into the atmosphere etc. Just the initial craters will all be a bit smaller but that's only the initial superficial damage. The real trouble starts afterwards from the tidal waves and climate change and those will be worse with multiple ELE type strikes.
