Stellar Gravitational Lensing as Interstellar Relay Points: A SETI Proposal and Alpha Centauri Observation

To the point

Nick Tusay and Macy Huston, guided by Jason Wright, propose that gravity near stars could bend and magnify radio signals to create a galaxy‑spanning relay network of probes, tested by pointing the Green Bank Telescope at Alpha Centauri but yielding no detections in a single night, with future work suggested including extended searches or relay probes, and a paper on the idea is accepted by The Astronomical Journal with a preprint on arXiv.
