Dark energy has been described as the biggest problem in cosmology. In new work, I suggest that we have been looking at the problem in the wrong fashion.
Abstract. The timescape cosmology has been proposed as a viable alternative to homogeneous cosmologies with dark energy. It realizes cosmic acceleration as ...
