The Cosmic Rosetta Stone,
adapted from an article in Physics Today (November 1997, p.32) by
Chuck Bennett, Michael Turner and Martin White.
The ten's of microKelvin variations in the temperature of the cosmic microwave background (CMB) radiation across the sky encode a wealth of information about the Universe. The full-sky, high-resolution maps of the CMB that will be made in the next decade should determine cosmological parameters to unprecedented precision and sharply test inflation and other theories of the early Universe.
