Spontaneous Dimensional Reduction in Short-Distance Quantum Gravity?

Several lines of evidence suggest that quantum gravity at very short distances may behave effectively as a two-dimensional theory. I summarize these hints, and offer an additional argumentbasedon the strong-coupling limit of the Wheeler-DeWitt equation. The resulting scenario suggests a novel approa...

Description
Summary:Several lines of evidence suggest that quantum gravity at very short distances may behave effectively as a two-dimensional theory. I summarize these hints, and offer an additional argumentbasedon the strong-coupling limit of the Wheeler-DeWitt equation. The resulting scenario suggests a novel approach to quantum gravity at the Planck scale.
