Fuzzy Space Time, Quantum Geometry and Cosmology
arXiv:physics/0301015
Abstract
It is argued that a noncommutative geometry of spacetime leads to a reconciliation of electromagnetism and gravitation while providing an underpinning to Weyl's geometry. It also leads to a cosmology consistent with observation. A few other ramifications are also examined.
