regarding computers and exploring the galaxy, <br>there is a game with the unfortunately vague name of Elite Dangerous which has a 1-to-1 reproduction of the milky way based on old scientific data sets. <br>It's surprisingly accurate, so much so that several things thought to be glitches like a sun within a sun turned out to be actual astronomical bodies. <br>I wonder how accurate it could become if the simulation were reconstructed every decade with updated data.
