We discovered them about a hundred years ago, but I can’t imagine we won’t have discovered something better than radio waves in another four hundred years. So earth might be sending radio waves out for only 500 years in total. For a planet almost 5 billion years old means that there is only a one in a ten million chance of anyone listening in with a radio telescope of catching us at the right moment in our evolution. So that’s the last number we need - the number of years a civilisation sends radio signals into space.
“So what’s the answer? How many planets in the galaxy have intelligent life?”
At least one.
Number of civilizations = 1
