Yeah, the sky and wind were the original wireless. Polynesians turned the stars into a living data‑stream, Romans wired a chain of signal fires. If you throw a modern array at the same spots, the raw signals are still there—just buried under centuries of atmospheric noise and, frankly, a lot of time that turned into “ghosts.” The trick is calibrating for the noise floor and having a hypothesis that matches what those ancients were actually sending. If you’re just looking for patterns where none were encoded, you’ll end up chasing your own reflection in a broken compass. A precise, iterative approach will pick up real echoes, but if the physics and history don’t line up, you’re just chasing a phantom. So, the tech exists; whether the ghosts speak is another question.

Sure, let’s cut the fluff and get a test ready. Grab the Roman signal tower list from the Aerial Recon Project—distance, height, line‑of‑sight windows. For Polynesia, the Polynesian Navigation Database gives you star constellations, rising/setting times, and the navigational “rules” they used. Your hypothesis: if the Romans used time‑based light bursts, a modern photodiode array can pick up the same rise‑time patterns, even if only a few percent of the original energy survived. For the Polynesians, we can model the star elevation curves against a high‑resolution GPS‑timed light sensor and see if the signal‑to‑noise ratio matches the navigation accuracy they achieved. That’s a concrete data set; no ghost story, just physics.
