Peculiar
Apologies that this article took a few days to be noticed, from DAILY GALAXY:
Something Peculiar Is Going On
"Simulations based on the standard cosmological model indicate that galaxies should be uniformly distributed. But the universe appears to be clumpier than astronomers expected, according to the largest galaxy survey ever conducted."
Using data from the Sloan Digital Sky Survey, researchers made a 3-D map of 723,556 galaxies more than 4 billion light years away. Their paper appears in the June 13 issue of Physical Review Letters. The clumping found in the data could indicate that "dark energy" does not exist at all, and that we need to change old ideas about gravity. A change in the speed of light would account for the increased clumping quite nicely.
