View Full Version : Are Galaxy Clusters Corrupting Our View of the Big Bang?

SUMMARY: Astronomers made news in early 2003 with a precise measurement for the age of the Universe - 13.7 billion years - using data from NASA's Wilkinson Microwave Anisotropy Probe (WMAP) satellite. But new research from the University of Durham indicates that our view into the past might be skewed by clusters of galaxies which seem to be in regions where the microwave energy is lower. It's possible that hot gas in the galaxy clusters is interfering with photons from the Big Bang, and has corrupted the microwave map of the sky. These results may undermine theories about how the early Universe was dominated by dark matter and dark energy.
