Cosmological inflation and string theory
Max-Planck-Institut für Physik, München
SummaryThe precise measurement of the fluctuations in the cosmic microwave background confirms the model that in the early universe a period of rapid expansion of its todays visible part has taken place. The detection of remnant gravitational waves from this period would be another milestone of experimental cosmology and would have important theoretical consequences. The theoretical department of the Max-Planck-Institut für Physik is working on building theoretical models of inflation that are based on string theory, the candidate for a theory of quantum gravity.
