Astronomers developed a diagnostic tool—the Pincus-Lyapunov diagram—that plots transient events in a chaos-versus-randomness space. When they mapped burst sequences from five repeating FRBs, five magnetars, solar flares, and earthquakes onto this diagram, repeating FRBs occupied a distinct region, statistically separate from magnetars and pulsar glitches. This suggests FRB mechanisms are fundamentally different from competing models.
