Limits on the Measurability of Space-time Distances in (the Semi-classical Approximation of) Quantum Gravity

Abstract

By taking into account both quantum mechanical and general relativistic effects, I derive an equation that describes some limitations on the measurability of space-time distances. I then discuss possible features of quantum gravity which are suggested by this equation.
