How Smooth is the Universe? | ScienceBlogs
"A cloud is made of billows upon billows upon billows that look like clouds. As you come closer to a cloud you don't get something smooth, but irregularities at a smaller scale." -Benoit Mandelbrot It isn't just the clouds that appear smooth, but aren't if you zoom in close.
