It’s been a long while since I last did a long theory post, hasn’t it? Hopefully this is worth the wait!
So. Unless the technology in Starbound’s universe operates on principles entirely outside my understanding (which is possible), the ability to communicate long-distance is going to be a serious concern for the intergalactic traveler. Somehow, Esther is able to keep in touch with us no matter where we are, but considering that NPCs have us passing notes, it’s clear the lo-tech stuff hasn’t gone out of style. What’s this mean for worldbuilding?
Communication in space operates on a time delay, thanks to the limited speed of light. Just communicating with Mars takes an average of not quite 14 minutes. That’s a very long time if, say, your moon base is under attack and you’re trying to get the evacuation order from your boss on the planet below. It’ll be even worse with communicating between star systems, and there’s nothing that can be done to improve this, short of breaking the laws of physics. Small wonder the Apex rebellion’s got a solid foothold against the better-equipped Miniknog. They operate out of small regional cells, not dependent on outside powers for instruction, and can take advantage of the communication delay to disrupt the chain of command.
But how does Esther keep in touch? By breaking the laws of physics after all. There’s one substance we know of in Starbound that’s capable of bending space-time and moving things faster than light: Erchius. Supposedly volatile, dangerous to mine, and little understood, this stuff can warp ships between distant star systems, so it’s probably possible to have an erchius-powered device that can run a sort of mini-warp to send data, intel, and voice-chat along. It’s probably not easy to maintain, though, costing heavily on fuel and energy. Your average intrepid Apex rebel can still cripple Miniknog responses once they discover where the communication hub is and disable it until a replacement can be found. Major settlements and military bases might be equipped with such devices, and a spaceship with a FTL drive can probably rig something equivalent to piggyback off the drive, but your average space-colonist isn’t going to be able to afford something this rare. Especially not with Letheia’s chokehold on the erchius market.
That’s where the note-passing comes in. Wireless networks are a work in progress in the frontier, planet-wide and maybe barely system-wide if you’re lucky. For reaching things out of your range, write a note, pay a visiting merchant/space captain, and hope they deliver it where it’s going. Some penguin gangs, wandering novakid, and other hopeful explorers probably make good business as couriers. There might even be official mail teams; a final frontier revival of the Pony Express. If you and the recipient are lucky enough to both have teleporters, you can also send notes that way, or just visit in person.
…of course, this still doesn’t answer how Esther does things. The answer to that is definitely jumping into the deeply theoretical side, but she might use the Ark. She already left a radio recording rigged up to that Ancient Gate, and maybe even all Ancient Gates, transmitted from the one source where she’s sitting when we meet her. The Builders clearly knew how to bend space to suit themselves, if the Ancient Vaults are any indicators. If Esther can set a radio signal to a far-distant Gate that she has probably never visited in person, she’s probably able to reach our SAIL with ease, and SAIL can handle the rest.
