> I often imagine there is something like "subspace" or faster-than-light communication, and species across our galaxy are a bunch of chatterboxes chatting away.
I like to imagine, for the science fiction that I might write, a hypothetical phenomenon that allows instantaneous communication between two points (objects/particles/portals) but only after they have been "synced" or "bound" with each other, which must be done during physical contact.
So, you might construct two such "hyperspace modems", bind them with each other, then incur the initial cost of physically transporting one of them to another star system however many light years away, which may take years or decades but once it's there, communication between the two points would be instantaneous.
That's interesting. You could call your story Spooky Action. The Spooky channel need not be used exclusively by so-called advanced civilisations. In fact there are species on Earth now that are known to interact in evolutionarily useful ways with quantum effects. Of course, if Spooky is just entanglement the modem would be destroyed upon a single use. However, there could be an effectively unlimited supply of them occurring naturally.
This feels more feasible than SETI's hypothesis. Space was much smaller and was probably at just the right temperature to support life at a very early stage of the Universe.
