Title: Cosmic Acceleration Then and Now
Abstract: This talk will highlight some current issues in cosmological physics. Topics will include contrasting attitudes toward, ideas for, and language used to describe primordial and contemporary inflation, as well as recent cosmological observations and the tensions between some measurements. These tensions may be signs of systematic errors or they may point to impending disruption of the Lambda-cold-dark-matter paradigm and be harbingers of new physics. The talk will conclude with descriptions of some newer observational techniques and projects that should help clarify and resolve these issues.
