"Astronomers monitoring Comet Elenin have noticed the comet has decreased in brightness the past week, and the coma is now elongating and diffusing.
Some astronomers predict the comet will disintegrate
and not survive perihelion, its closest approach to the Sun."
I don't thing that's goog for planet Earth.
It will probable shower us with lot of junk.
Quoting: jarha when they say it 'won't survive perihelion', do they want us to believe an object 4 miles in diameter will simply POOF, vanish into thin air? or thin space, sorry.
do they REALLY think we're that stupid?
what is the weight of material of a comet 4 KMs in diameter, material being SCATTERED in relatively close proximity to us, speaking in terms of space?
well, they have a density of 0.6g per cubic cm on average, so that's 600 kilos per cubic metre, and there's 64 billion cubic metres in a comet 4 Kms wide, assuming it's a perfect square, of course.
anyway, by my very rough calculations, that makes 38 billion 400 million metric tons of stuff that 'won't survive'? I think it's safe to say that it isn't a perfect square, but the 'disintegrated' material out there will still be in the 10s of billions of tons. Even a TINY fraction of that hitting us would be pretty bad.
nice.
