Artistic impression of the Double Pulsar system, where two active pulsars (emitting beams of radio waves) orbit each other in just 147 min. The orbital motion of these extremely dense neutrons star causes a number of relativistic effects, including the creation of ripples in spacetime known as gravitational waves. The gravitational waves carry away energy from the systems, which shrinks by about 7mm per days as a result. The corresponding measurement agrees with the prediction of general relativity within 0.013%.

Michael Kramer/MPIfR - Einstein's theory of gravity, general relativity, has not been disproven once in over a century, despite relentless efforts from scientists to find its faults. Pulsars are stars toward the end of the stellar life cycle, emitting radio waves that sweep through space like a lighthouse: they can be detected by radio telescopes in the form of highly regular flashes. Seven radio telescopes observed a double pulsar for 16 years, thereby enabling a series of high-precision tests of the theory of general relativity..
