An article on news.discovery.com titled, "The Universe is Precisely 13.75 Billion Years Old" on Feb. 4 says: "The amount of CMB radiation spotted near clusters of galaxies is greater than expected. According to [cosmological] theory, CMB photons should interact with these clusters, getting kicked to higher energies. WMAP cannot detect these higher energy photons, so there should be a deficit of CMB photons around clusters. This is not the case and scientists will probably be confused by this for some time to come." What ideas of cosmological theory might this make us rethink?
