If confirmed, timing its radio pulses could test General Relativity with unprecedented precision. Pulses traveling through curved spacetime experience Shapiro delay, gravitational redshift, and frame dragging from the spinning black hole. Each effect leaves a signature in the timing residuals — the difference between expected and observed pulse arrivals.","shortDescription":"Pulsar timing tests General Relativity near a black hole"}}
