uhhh................. ok?

Clouds dont fall because when they do fall we just rename them Fog and pretend nothing ever happened.

I usually call falling clouds rain or snow.

any of you curious about the "Black Body" thing (ie if something absorbed all inciddent light) should read this first...

http://en.wikipedia.org/wiki/Black_body

http://en.wikipedia.org/wiki/Colour

as for how something "perfectly" black would appear, thats interesting and I'm not entirely sure about it.

"Normal" black objects we see because they aren't perfectly black (I assume) because in light they also reflect part of the light inciddent on them. If you could make something that is perfectly black and had no reflections from its surface, I guess it probably would be harder to see.

This is assuming it doesn't get very hot ( <700C)

The problem with this though is the eye itself, it "sees" a lot more than just the object itself, it would infer its existance through the other objects nearby, much like a Black Hole is inferred through the gravitational Lensing effect.

i suggest you guys/(gals....) watch What the Bleep do We Know - brain twister.cool.

No. Hell no. It's just one big advertisement for new-age bull**** covered up with a thin layer of "science". Which makes it worse because they're trying to pass it off as real. I hated that movie.

EDIT: If you want to watch something about real physics that will really blow your mind, you can watch "The Elegant Universe" online for free.

kyle, none of the links work for me. site says it could be because of high demand

never known high demand to lead to a 'page could not be displayed'

PBS? High demand? Does not compute.

That's weird, they work fine for me... well other than whenever I close it it crashes Firefox (but then again, what doesn't crash FF?).

I remember having to go through some horrendously complex series of steps in order for quicktime to play embedded mp3s in websites; maybe it's the same for video.
