• General relativity (GR) predicts concordant trajectories for photons and gravitational waves (GWs). We propose a new multimessenger avenue (GW-CMB-CMB) to prove this aspect of fundamental physics by cross-correlating the GW signal of astrophysical origin with the lensing field derived from the cosmic microwave background (CMB). This new window will allow robust measurement of the prediction from GR with high signal-to-noise ratio and will be able to unveil the true nature of gravity using the GW sources detected by missions such as the Laser Interferometer Space Antenna, Einstein Telescope, and Cosmic Explorer.
