I have a question that I have been contemplating for some time, it is: If a large comet made a close pass to the earth and shed a large amount of water/ice and this water/ice was captured by the gravitational pull of the earth, how exactly would this water/ice reach the surface of the earth? As rain?

If the core survived, the impact would destroy it (vaporize). You might see a contrail i think.

"If the core survived, the impact would destroy it (vaporize). You might see a contrail i think." I'm talking about a big comet that has a tail larger than the earth that does not impact. A close pass.

I don't think the gravity well goes all the way to the bottom under a comet. </humor
I would have to think it would reach the surface the same way as any other water/vapor that occurs above the Earth's surface....

As rain? Wouldn't it just be water vapor and blend in with the other molecules? And might precip out as rain at some point!

The tail of the comet is all gas, so the water vapor would mix as vapor with the atmosphere. Eventually it would precipitate out to the ground.

I remember reading that in 1910, the Earth actually passed through the tail of Halley's Comet. The ice particles, since they are moving so fast (tens of thousands of miles per hour) that they would instantly vaporize in the Earth's atmosphere.

"The fact that the tail 'holds together' so well probably means that the dust is mostly the same size," The dust is probably very fine, like silt. The water ice, once it is free as a kind of dust would evaporate in the vacuum, sublimate.

Not likely. You would still be left with the question of where did the water. Perhaps best not to look for naturalistic explanations.

should read: "where did the water go?"

If you can imagine the world covered to the tops of the mountains, you must also imagine the water draining somehow. I would be interested in understanding where the water went.

It would be interesting to see other cultural references to this worldwide flood.

I don't think so. A comet or asteroid striking one of the oceans could cause A LOT of coastal flooding, and if it broke into fragments beforehand, and the Earth spun a bit before it impacted, it could cause another catastrophic flood.

It's the Small Comets, as described by the University of Iowa that have deposited the water on Earth!

Try the story of Gilgamesh. It is supposedly the oldest ancient epic tale ever recovered (way before the Bible). It is the story of the King Gilgamesh who ruled in Iraq (yep, a little south of Mt Ararat). After his best friend, Enkidu, died, Gilgamesh sought the meaning of life, death and immortality.
He made an attempt to descend into 'hell,' (the seeds of the Greek's Orpheus) but did not get too far. Some old, dusty hole in the ground, ha ha ha.
Then the story relates his long journey in search of his 'father,' an old man who had survived the flood and had the secret of immortality:
"He [Gilgamesh] longed to hear the voice of one
Who still used words as revelations;
He yearned to talk to Utnapishtim,
The one who had survived the flood
And death itself, the one who knew the secret." (source: "Gilgamesh" a verse narrative by Herbert Mason, New American Library (Signet), 1972)

"If you can imagine the world covered to the tops of the mountains, you must also imagine the water draining somehow. I would be interested in understanding where the water went."Maybe not to the top of all mountains.
I was thinking that I've tied a number of catastrophic events to different times and imagery from the bible...and I've always thought that the flood described in the bible was probably the flooding from the end of the Ice Age (or the Black Sea flood) but, that doesn't quite do it.
I'm looking for lots of rain (40 days & 40 nights). The number forty is a mistranslation that should read 'many.' But a lot of rain none-the-less.
