Flaw of averages: Is ordinary matter causing the cosmos to accelerate?

Article Abstract:

A group of cosmologists contended that the acceleration of cosmic expansion is among the biggest mysteries of modern science and an odd effect. It could be the most formal explanation for acceleration proposed, requiring neither exotic forms of energy nor new laws of physics, a careful accounting of how gravity interconnects structures of different size.
