The cosmic Dark Sector

*It wouldn't surprise me much to learn that Dark Energy and Dark Matter, which are allegedly most of the universe, are very complex and where all the real cosmic action is, whereas visible matter, the stuff we're made of, is just a froth, or trash.

*When you're in a Copernican universe, it's important to realize that your apparent starring role can get radically downgraded any time.

"About four years ago, James Bullock, a professor of physics and astronomy at the University of California, Irvine, began to wonder whether the standard view of dark matter was failing important empirical tests. “This was the point where I really started thinking hard about alternatives,” he said.

"Bullock thinks that dark matter might instead be complex, something that interacts with itself strongly in the way that ordinary matter interacts with itself to form intricate structures like atoms and atomic elements. Such a self-interacting dark matter, Bullock suspects, could exist in a “dark sector,” somewhat parallel to our own light sector, but detectable only through the way it affects gravity…."
