Will We Actually Be Able to Detect a Signal from an Alien Intelligence? (Weekend Feature)

Alien Signal

 

British physicist Stephen Wolfram believes extraterrestrial intelligent life is inevitable, but with a caveat. Although intelligent life is inevitable, we will never find it. Wolfram says that  in order to compress more and more information into our communication signals – be they mobile phone conversations or computers – we remove all redundancy or pattern. If anything in a signal repeats, then it can be deleted. But this process of removing any pattern from a signal makes the signal look more and more random – in fact, pretty much like the random radio “noise” that rains down on Earth coming from stars and interstellar gas clouds.

Alien Technology

 

“Machine learning provides a way of providing almost human-like intuition to huge data sets.  One valuable application is for tasks where it’s difficult to write a specific algorithm to search for something—human faces, for instance, or perhaps “something strange,” wrote astrophysicist and Director of the Penn State University Extraterrestrial Intelligence Center, Jason Wright in an email to The Daily Galaxy. “In this case, you can train a machine-learning algorithm to recognize certain things you expect to see in a data set,” Wright explains, “and ask it for things that don’t fit those expectations, or perhaps that match your expectations of a technosignature.

Origin of Life

 

British physicist Stephen Wolfram believes extraterrestrial intelligent life is inevitable, but with a caveat. Although intelligent life is inevitable, we will never find it -at least not by searching in the Milky Way.  We have a slim chance, he suggests, of distinguishing an ET artifact from a natural celestial object.

“This data release is a tremendous milestone for the Breakthrough Listen team,” said Dr. Danny Price of the search “pipeline” that scans through billions of radio channels, looking for signals of radio-transmitting extraterrestrial civilizations in our Galactic neighborhood that are too narrow and well-defined to result from natural processes.
