Dried water spots and the universe

[Jiggerj]

This morning I was outside where the light of the sun hit my eyeglasses at an angle that showed round, dried water spots. What struck me as odd is how the particles of dust and dirt were so evenly dispersed throughout the water spot. Then I remembered watching a documentary on the universe where a physicist asked, "Why are the objects in the universe so evenly dispersed?'

 

Is there some connection between the two (dried water spots and the universe)? I mean, are there similar laws involved on how things get dispersed through space and some kind of liquid?
