Those are rookie numbers. Ok so not the same, but headline made me think of NANOGrav first, which uses minute shifts in pulsar timings to detect gravitational waves in the nano-Hz range[1]. The submission was about subs rather, and quite interesting as such. The ELF system was found to cause problems ranging from flickering light bulbs to phantom telephone ringing, and the Navy installed additional grounding and filtering on public utilities throughout the…</p><p><a href="https://hackerpaper.kaipfister.de/p/2306.16218/">Paper and discussion history</a>.
