Intelligent Life Really Can’t Exist Anywhere Else Hell, our own evolution on Earth was pure luck. In research published in 2020 from Oxford University's Future of Humanity Institute, scientists study the likelihood of key times for evolution of life on Earth and conclude that it would be virtually impossible for that life to evolve the same way somewhere else. Life has come a very long way in a very short time on Earth, relatively speaking—and scientists say that represents even more improbable luck for intelligent life that is rare to begin with. For decades, scientists and even philosophers have chased...

Congress made two startling claims. The first is that “cross-domain transmedium threats to the United States national security are expanding exponentially.” The second is that it wants to distinguish between UFOs that are human in origin and those that are not: “Temporary nonattributed objects, or those that are positively identified as man-made after analysis, will be passed to appropriate offices and should not be considered under the definition as unidentified aerospace-undersea phenomena,” the document states. What does all this jargon mean, though? One key word in the congressional report is “transmedium,” a term the Pentagon has recently adopted for its...

How do you get machines to perform better? Tell them they could croak at any minute. In a new paper from the University of Southern California, scientists say that “in a dynamic and unpredictable world, an intelligent agent should hold its own meta-goal of self-preservation.” This idea invokes the design concept of a survival game, where a finite number of resources is given to a set number of players and they must find an equilibrium or eliminate their competitors. The gorgeous 2018 card game Shipwreck Arcana is a great example of a cooperative survival game: To win, at least one...
