"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."

I'm looking for the cause of the worldwide bibical flood, could something like this be it?

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

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.

Melting glaciers?

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.
