To me the most straightforward thing to think about is EM waves at frequencies we can only imagine. Very different sources and detectors from what we have, therefore the radiation is undetectable to us (also very line-of-sight), but still the same physics in terms of the properties-of-the-universe required. I would imagine this increase would be developed for the same reason we have gone from KHz to GHz in a hundred-odd years: The higher the frequency the more information you can transmit per second.
- saltcured 8y agoSo, you're thinking those cosmic rays are really symbols in an alien modulation scheme? Quasars are really light houses...?
- dhimes 8y agoHa ha yeah that would be scary-cool-- the cosmic charts showing black holes to avoid and such.
- saagarjha 8y agoThe issue with high frequency communication is the power needed to sustain it, since energy goes up as wavelength decreases.
- dhimes 8y agoI suspect that's not the biggest issue. Developing the tech to create a and detect a modulated wave at these frequencies is way bigger, IMHO. You might be using nuclei as detectors, for example. But in my imagination I can see this being solved.
- Procrastes 8y agoMaybe it looks something like this: https://www.technologyreview.com/s/611977/get-ready-for-atomic-radio/ https://www.technologyreview.com/s/611977/get-ready-for-atom...
- dhimes 8y agoYeah- maybe using a nuclear version of this ("Rydberg nuclei?"). Thanks for the link!
