From National Geographic News:Dark Energy's Demise? New Theory Doesn't Use the Force"Dark energy, a mysterious force proposed more than a decade ago to explain why the universe is flying apart at an increasingly faster clip, is no longer necessary. That's the conclusion of a controversial new theory that shows how the accelerated expansion of the universe could be just an illusion."The article refers to work by Blake Temple of UC Davis and Joel Smoller of University of Michigan. Their work suggests that our galaxy is in the middle of a density fluctuation that mimics the effects of an accelerating universe. This would explain supernova data without cosmic acceleration, but violate the Copernican Principle.The inferrence of a repulsive "dark energy" has led science nowhere. Focus on DE is one more factor eroding the reputation of physics. These new theories are nails in the coffin of DE. As readers know, the data can be precisely matched by GM=tc^3 and a changing speed of light.
