The Universe Is Smooth, Not A Fractal At Large Scales, Say Astronomers_Featured_, Space Friday, August 24th, 2012
(By Jeff Blagdon | The Verge)
Our current picture of the universe goes like this: hundreds of billions of stars group together to form galaxies, galaxies clump together to form clusters, and clusters clump together to form superclusters. In other words, the universe exhibits properties of a fractal — the same “lumpy” pattern is visible whether we’re looking at the galaxy scale or the supercluster scale.
We can say with a high degree of certainty that our picture of the large-scale Universe is correct.
The question is what happens when we zoom out farther?
