Re:Speculation - 2005/07/24 04:52
"The major surprise was the opacity of the plume the impactor created and the light it gave off," said Deep Impact Principal Investigator Dr. Michael A'Hearn of the University of Maryland, College Park. "That suggests the dust excavated from the comet's surface was extremely fine, more like talcum powder than beach sand. And the surface is definitely not what most people think of when they think of comets -- an ice cube."
dust excavated from the comet's surface was extremely fine, more like talcum powder .
Ok here is some speculation which I am a little nervous about however, here goes:
The reason why the sky is blue is because the extremely fine particles suspended in our atmosphere scatter the blue light which is a component of the Sun's white light.
So with the blue light scattered what remains is the red light.
If the fine dust particles from the comet do the same the blue light could be entirely scattered out before it even reaches our planet leaving us with red light only.
Only red light would make it to the moon and be reflected and the sun would certainly appear darkened.
Heres a link to the sky colour thing:

Just speculating.
