Resumen:
A universal inequality that bounds the angular momentum of a body by the square of its size is presentedand heuristic physical arguments are given to support it. We prove a version of this inequality, asconsequence of the Einstein equations, for the case of rotating axially symmetric, constant density, bodies.Finally, the physical relevance of this result is discussed.
