What is the chance we start a conversation with another civilization like ourown? Our technological society produced signals that could be received by otherextraterrestrial civilizations, within a sphere around us with a radius of$\sim 10^2$ light years. Given that, the Copernican principle provides a lowerlimit on the response time that we should expect from transmitters onEarth-like planets around Sun-like stars. If our civilization lives longer, theexpected number of responses could increase. We explore the chance of detectinga response in the future, and show that a response should only be expected toarrive after a few millennia.

Intelligent Responses to Our Technological Signals Will Not Arrive In Fewer Than Three Millennia
