This tool helps to better detect aliens

This innovative approach boosts the chances of finding extraterrestrial intelligence in our galaxy by using probability theory to calculate the possibility of detecting an extraterrestrial signal at a given distance from Earth



Scientists from Ecole Polytechnique Fédérale de Lausanne and University of California, Berkeley have developed a statistical model that gives researchers a new tool in the search for the kind of signals that an alien society might emit. This can also make the search cheaper and more efficient.


The advantage of this statistical model is that it lets scientists deduce both the success and failure to detect signals at variable distances from Earth. It employs Bayes' theorem to compute the remaining probability of identifying a signal within a given radius around our planet.
