  • Duncan Forgan at the University of St Andrews, UK, modeled 500 points in the galaxy, each representing a civilization that can manipulate its planet's transit in a visible way. That's relatively conservative; some researchers estimate there could be millions of alien societies that advanced. He determined how long it would take for each point to be lined up to see a transit at another point, slowly building a web across the galaxy. Chatting with them all would need a kind of relay network to avoid celestial obstacles.
