Professor Lawrence Krauss
Arizona State University

The last decade or two have represented the golden age of observational cosmology, producing a revolution in our picture of the Universe on its largest scales, and perhaps also its smallest ones. I will argue that these recent developments bring to the forefront some vexing questions about whether various fundamental assumptions about the universe are in fact falsifiable. I will focus on 3 issues:

1. Exploring the physics of the early universe,
2. Determining the nature of mysterious energy of empty space that remarkably seems to be causing the expansion of the universe to be speeding up, and its implications for understanding the origin of the fundamental constants of physics and
3. Cosmology of the far future, and the possibility that all evidence for the big bang will disappear.

Prof. Krauss researches at the interface between elementary particle physics and cosmology. He is a Fellow of the American Physical Society and of the American Association for the Advancement of Science. He is involved in issues of science and society and is the author of many popular book
