Could game theory help discover intelligent alien life?

New research from the University of Manchester suggests using a strategy linked to cooperative game playing known as 'game theory' in order to maximize the potential of finding intelligent alien life.
If advanced alien civilisations exist in our galaxy and are trying to communicate with us, what's the best way to find them? This is the grand challenge for astronomers engaged in the Search for Extraterrestrial Intelligence (SETI). A new paper published in The Astronomical Journal by Jodrell Bank astrophysicist, Dr. Eamonn Kerins, proposes a new strategy based on game theory that could tip the odds of finding them more in our favor.
SETI programs tend to use one of two approaches. One is to conduct a survey that sweeps large areas of sky in the hope of seeing a signal from somewhere. This survey approach can quickly generate huge volumes of data that can be very hard to search through comprehensively. An alternative approach is targeted SETI, where the search focuses more intensively on specific star systems where life might exist. This provides more comprehensive data on those systems, but maybe there's nobody there?
SpaceX vs NASA: Who will get us to the moon first? Here's how their latest rockets compare

No one has visited the moon since 1972. But with the advent of commercial human spaceflight, the urge to return is resurgent and generating a new space race. NASA has selected the private company SpaceX to be part of its commercial spaceflight operations, but the firm is also pursuing its own space exploration agenda.
To enable flights to the moon and beyond, both NASA and SpaceX are developing new heavy lift rockets: SpaceX's Starship and NASA's Space Launch System.
But how do they differ and which one is more powerful?
Starship
Rockets go through multiple stages to get into orbit. By discarding spent fuel tanks while in flight, the rocket becomes lighter and therefore easier to accelerate. Once in operation, SpaceX's launch system will be comprised of two stages: the launch vehicle known as "BFR" (Big Falcon Rocket) and the Starship.
BFR is powered by the Raptor rocket engine, burning a combination of liquid methane and liquid oxygen.
