Cosmic oddity casts doubt on theory of universe

A new analysis of the "echo" of the Big Bang has left cosmologists scratching their heads and could throw a monkey wrench into efforts to understand how the universe began.
U.S. and European scientists analyzed the distribution of "hot" and "cold" regions -- areas that are putting out greater or less amounts of energy than the average -- of the cosmic microwave background radiation (the so-called echo). What they found was unexpected: an apparent correlation between those hot and cold spots and the orientation and motion of our solar system.
"All of this is mysterious," says Glenn Starkman, a Canadian physicist based at Case Western Reserve University in Cleveland and one of the authors of a recent paper in Physical Review Letters that outlined the finding. "And the strange thing is, the more you delve into it, the more mysteries you find."
The study, by Case Western scientists and the European Centre for Nuclear Research in Geneva, is based on data from the WMAP satellite, the NASA spacecraft that began mapping the cosmic microwave background (CMB) radiation in fine detail in 2001.
The observed correlation is troubling on several fronts.
