If you're looking for reasons why humanity has not found any aliens yet, you can find a lot. We never left our solar system, set foot on another planet, and while our telescope technology allows us to observe distant planets, we do not have the ability to see what actually happens. Looking for reasons why the aliens have not found us, on the other hand, it's a bit harder to answer. A new work by Michael Hippke, a researcher at the Sonnenberg Observatory in Germany, offers a possible explanation that you probably never mentioned before.

Hippke suggests that extraterrestrial "space programs" could struggle with the technology needed to send them into space, especially if they live in one of the many "super-lands" that astronomers have discovered in recent years. Years. These huge worlds, which can look like Earth, are twice as big as our planet, which would mean a significant increase in gravity. The result could be intelligent civilizations that simply can not fend off their own planet.
