Cosmic strings arise as remnants of phase transitions in the early Universe, often related to theories of grand unification (GUTs). If such a phase transitions occurs at high energies, the resulting cosmic string network generates a sizable amount of gravitational waves. Most work so far has focused on the gravitational wave signal from topologically stable cosmic strings. In this talk I will introduce metastable cosmic strings, which are a generic consequence of many GUTs, are largely unconstrained so far but can be probed by current and upcoming gravitational wave experiments. As a concrete example, I will present an SO(10) model which explains inflation, baryogenesis and dark matter while being fully testable by LIGO .
