Inequality between size and angular momentum for bodies

General Relativity and Quantum Cosmology 2014-02-05 v2

Abstract

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