View Full Version : Dust?

2007-Mar-11, 02:05 AM
On the podcast I here Pamela talk about the dust in space. I have always pictured space dust to be a lot like the dust under my couch. But the more and more I come to some grip or understanding with just how VAST the Universe is I started wondering if dust in space was much larger then here on earth but just dust when compared to the overall size of galaxies etc.

So...if I had a piece of dust that we see in distance galaxies etc here in my hand...how big would it be?
