For me, "super earths" are just EARTH-SAME exoplanets!!

 ...and NOT Earth-like.




Only EXO-PLANETS SAME TO EARTH should be searched, where mass + size differ at most 10% with TERRA. So I'm by no means thinking of the "super-earths" that have been praised more often in recent times but are misleading and are 2/3 times as big or massive as our earth !!
Because the strong gravitational forces there make grasping systems too clumsy (if at all) in creatures and thwart such fine-motor tool-making as gadgets/computer manipulation. There is also no trace of the upright gait, which is important here, with probably extremely compact - even 6/8-legged - "creeping animals". Everything that doesn't resemble our great apes has a hard time forming adequate arms + hands (I've already explained this in more detail in other articles)! However, these are the most important prerequisites for the formation and evolution of intelligence.



It may be that on significantly smaller earths there will be animal-like ones whose longer + narrower limbs also have good cards there. Upright gait is also probably dominant here, because bipeds will suffice with significantly less gravitational pull. But what use is it if a planet that is too small cannot form an atmosphere - at least it cannot hold it in the long term. The best example of this is our Mars. The relevant protection from magnetic fields is also hardly given here.



It stays that way:
If you are looking for (radio telescope) technical civilizations, the alien earth should only be SOMETHING larger or smaller than our earth! EQUAL to earth and not earth-like! ! Unfortunately, "sun scanner" Keppler discovered only one of the several thousand discovered planets SAME TO EARTH. It is to be expected that successor TESS will achieve more. TESS scans an area several times larger and it is also much closer. Relatively small EARTH-SAME planets are easier to locate...
