Thinking about how Grace casually gave Rocky a computer with basically All Human Knowledge.
How did the people of Erid feel when they got that? I mean, here's this thinking machine they apparently had no concept of, containing all this advanced knowledge of things they had no idea about like radiation and relativity...
My headcanon is that they're gonna feel like total assholes for not sending something similar back, so they end up using the laptop and Grace to make a human-compatible primer of Eridian science including the recipe for xenonite and their spaceship, then launch it towards Earth.
But the laptop didn't have just science texts; it had fiction and music and games. So they add a bunch of Eridian cultural stuff too.
So now there's this ocassional information exchange between planets lightyears away from each other that use astrophage to send probes full of the latest knowledge and news. By the time the civilizations advance enough to travel and contact, Earth and Erid are like old friends.
