Spacetime and Noncommutative Geometry

This talk, which is intended for non-specialists and makes particular emphasis on astrophysical/cosmological implications, will review the underlying physical motivations for the suggestions that spacetime is noncommutative. Causality violations are implied by such noncommutativity and that leads to physical effects. It also leads to Pauli principle violations and forbidden transitions, and to observable effects in CMB temperature spectrum. Finally it has definite predictions about CPT and Lorentz invariance violations in scattering. The talk discusses these aspects of spacetime noncommutativity as well.
