LIMITS ON THE MEASURABILITY OF SPACE-TIME DISTANCES IN (THE SEMICLASSICAL APPROXIMATION OF) QUANTUM GRAVITY
Abstract
By taking into account both quantum mechanical and general relativistic effects, an equation that describes some limitations on the measurability of space-time distances can be derived. We then discuss possible features of quantum gravity which are suggested by this equation.
