Vacuum spacetime with multipole moments: the minimal size conjecture and gravitational wave observables Shammi Tahura, PhD; University of Iowa It is reasonable to expect that a bound source cannot produce arbitrarily large gravitational multipole moments. By observing the behavior of spacetime metric with large multipole moments at small distances from the source, we conjecture that for a sufficiently large multipole moment, there is a minimal size below which no object in nature can suppo...
