SETI Director Warns: Those Aliens Could Be Malevolent

Harvard astronomer agrees: We’ve sent a lot of signals in recent years; they may have got them. But now what?

As the Mars Rover Perseverance bumps around looking for fossil bacteria and such, many students of possible ET life are becoming surprisingly cautious about what it might mean: “We have no reason to believe that technological advancement and altruism or morality are somehow linked,” SETI researcher Andrew Siemion told Inverse. “There probably are malevolent civilizations elsewhere in the universe so that’s certainly something that we should consider as we continue to explore the universe.” Siemion, who’s the director of the Berkeley SETI Research Center and principal of the alien-hunting Breakthrough Listen project, is invoking a tension at the heart of any project searching for alien life.

We Are Warned: Don’t Try To Colonize Super-Earths

Theoretical astrophysicist Ethan Siegel tells us why he thinks it would end in disaster

According to NASA, super-Earth planets are “a class of planets unlike any in our solar system – are more massive than Earth yet lighter than ice giants like Neptune and Uranus, and can be made of gas, rock or a combination of both. They are between twice the size of Earth and up to 10 times its mass.” Such plants are common in our galaxy and so far we have discovered 1,342 of them. Some are hot enough to vaporize metal; some are dim and frozen. An infographic from NASA of the TOI 270 system provides examples of super-Earths in relation to Earth: From NASA: “This infographic illustrates key features of the TOI 270 system, located about 73 light-years away…
