Dimension and dimensional reduction in quantum gravity

Abstract

© 2017 IOP Publishing Ltd. A number of very different approaches to quantum gravity contain a common thread, a hint that spacetime at very short distances becomes effectively two dimensional. I review this evidence, starting with a discussion of the physical meaning of 'dimension' and concluding with some speculative ideas of what dimensional reduction might mean for physics.
