Our Focus The Cosmic Microwave Background (as viewed by WMAP)
What is the CMB? …A remnant from the BIG BANG
Discovery of the CMB Robert Wilson and Arno Penzias, 1964
The CMB and the Early Universe The CMB provides clues as how the Universe expanded, or inflated to its current size
The CMB and the Early Universe The CMB also provides clues about the composition of the universe…
Evolution of the Universe
The CMB and Last Scattering
Looking Back in Time
The Structure of the Universe Early perturbations in the density of matter later give rise to the formation of galaxies…
