Abstract The elliptic loop equation of cosmic string is studied in the Minkowski space and during the radiation-dominated era in the Robertson- Walker universe. A remarkable fact about this equation is that a loop may never contract to one with a Schwarzschild radius, if it is sufficiently non-circular.
