# Cosmology, Inflation and the Physics of Nothing

@inproceedings{Kinney2003CosmologyIA, title={Cosmology, Inflation and the Physics of Nothing}, author={William H. Kinney}, year={2003} }

These four lectures cover four topics in modern cosmology: the cosmological constant, the cosmic microwave background, inflation, and cosmology at the Planck scale. The underlying theme is that cosmology gives us a unique window on the “physics of nothing,” or vacuum energy. The theory of inflation postulates that vacuum energy, or something very much like it, was the dominant force shaping the evolution of the very early universe. Recent astrophysical observations indicate that vacuum energy…
