For decades, scientists have searched the skies for signs of extraterrestrial technology. A study from EPFL asks a sharp question: if alien signals have already reached Earth without us noticing, what should we realistically expect to detect today?

The signal would have had to orginated hundreds of years ago and pointed at one part of their sky. A needle in an infintely large haystack.

The chance is infinitisimal.

The odds are astronomical.
