Researchers using measurements of the cosmic microwave background - a faintly glowing relic of the hot, dense, young universe - say their results provide support for the cosmological model of the universe - a prediction that dark matter and dark energy make up 95% of everything in existence while ordinary matter makes up just 5%. Writing in The Astrophysical Journal, researchers on the QUaD telescope project have released detailed maps of the cosmic microwave background (CMB); they focused their measurements on variations in the CMB's temperature and polarization to learn about the distribution of matter in the early universe. read more
