Physics

Scientific paper

The existing supernova measurements of the universe's (accelerating) expansion history have pointed the way to the next generation of experiments. This next generation of supernova measurements must be made with a dramatic step forward in constraints on systematic uncertainties, since the previous measurements already have statistical uncertainties that are close to the current systematics limits. I will show how some recent results set the stage for these advances, and describe a series of ground- and space-based projects and a new satellite experiment (the SuperNova / Acceleration Probe, "SNAP") that promise a systematics-controlled prize: a detailed expansion history of the universe that can teach us about the nature of the mysterious "dark energy" that accelerates the universe.
