Carnival of Space!
Steinn at Dynamics of Cats links to an interesting new paper:
Improved CMB Map from WMAP Data.
The paper takes issue with the standard interpretation of WIlkinson Microwave Anisotropy Probe data. Among other results, the new paper estimates the amount of missing mass, usually ascribed to "dark energy," at only 68%. This is exactly what a student's very short paper predicted back in 2004. Since then other models have been explored that give a proportion of 72%. Creating models where the speed of light slows down will keep physicists employed for decades. The "GM=tc^3" cosmology looks better and better.
