This newly-published research study suggests we shouldn't expect to hear from any alien civilizations for a long time - perhaps as long as another 400,000 years.

If there are so many galaxies, stars, and planets, where are all the aliens, and why haven't we heard from them?
Those are the simple questions at the heart of the Fermi Paradox. In a new paper, a pair of researchers ask the next obvious question: how long will we have to survive to hear from another alien civilization?
Their answer? 400,000 years.
400,000 years is a long time for a species that's only been around for a couple hundred thousand years and only discovered farming about 12,000 years ago.
But 400,000 years is how long we'll need to keep this human experiment going if we want to hear from any alien civilizations. That's according to some new research into Communicating Extraterrestrial Intelligent Civilizations (CETIs).
The paper is "The Number of Possible CETIs within Our Galaxy and the Communication Probability among These CETIs". The authors are Wenjie Song and He Gao, both from the Department of Astronomy at Beijing Normal University. The paper is published in The Astrophysical Journal. ...
