What is the CMB? …A remnant from the BIG BANG
4
Discovery of the CMB Robert Wilson and Arno Penzias, 1964
5
The CMB and the Early Universe The CMB provides clues as how the Universe expanded, or inflated to its current size
6
The CMB and the Early Universe The CMB also provides clues about the composition of the universe…

Gravitational Lensing
11
The Structure of the Universe Early perturbations in the density of matter later give rise to the formation of galaxies…
