So if we can somehow preserve the signal and make it go round and round, can we get long term storage out of nothing?

- lucaslazarus 9mo agoThis is possible but you'd have to deploy it right by a black hole: https://en.wikipedia.org/wiki/Photon_sphere https://en.wikipedia.org/wiki/Photon_sphere
- hidroto 9mo agoi wonder how sensitive your equipment would need to be to read it from the back scatter off the interstellar medium.
- terminalkeys 9mo agoNot a scientist, but I assume the signal would degrade or mutate over time due to space radiation and other radio waves.
- PartiallyTyped 9mo agoIt should be same logic we use for repeaters, so it'll be fine.
- Sesse__ 9mo agoThe logic we typically use for repeaters (EDFA, erbium-doped fiber amplifiers) for long-distance lines amplifies but does not clean noise (so across the oceans, you are very much bound by SNR). And you need one of them every 80 km or so in typical fiber.
- lxgr 9mo agoElectromagnetic waves have perfect/lossless superposition, so radiation can’t really degrade a signal that way. The big limiting factors are free space path loss and noise.
- Y_Y 9mo agoThat's only true in classical electrodynamics, as it happens. If you're in a very strong B-field like you might find near a compact object you'll get nonlinear QED effects. You can get a low order correction with Euler-Heisenberg: https://en.wikipedia.org/wiki/Euler%E2%80%93Heisenberg_Lagrangian https://en.wikipedia.org/wiki/Euler%E2%80%93Heisenberg_Lagra...
- marcosdumay 9mo ago"Nothing" is a funny name for an interplanetary communication network.
- idiotsecant 9mo agoYou're still storing your data in the same EM field, just in a slightly different non-inertial reference frame.
