A New View of Space from String Theory and String Cosmology

Robert Brandenberger (Physics Department, McGill University)

Abstract

String theory is the best candidate for a quantum theory which unifies all four known forces of nature. However, string theory is mathematically consistent only in a ten-dimensional space-time. This forces physicists to reconsider the role of space. The question of why we observe only three spatial dimensions now becomes a question which can be addressed using the tools of a physical science. I will discuss the changing role of space resulting from developments in string theory. I will also outline a new theory of the very early universe which results from combining string theory and cosmology.
