Europa, one of Jupiter's large moons, is predicted to have a salty ocean beneath its icy surface. This ocean is expected to have more liquid water than the oceans of Earth have. Virtually every place on Earth that we find liquid water we find at least microbial life. Based on this it seems likely that some form of life could exist on Europa. Of course, jumping from "there's a good chance there might be life" to "let's consider intelligent life" is a huge leap, but I'm mostly just bringing this up for fun speculation. As unlikely as it might be, the idea of intelligent life in that ocean is a interesting thought. It seems possible a species could actually become fairly advanced without ever seeing a star. Humans have had the luxury of being able to look up into the sky and see other planets and stars. If it just got colder and more dangerous the father you got from the center of the world and it just was dark off in that direction with no apparent goal to be seen, it might not seem very worth while to explore in that direction. Especially if you eventually reached the ice. A first assumption in this situation might just be that the water goes on forever, it just gets cold enough that it's solid from here on out. From this you could advance in other ways without any knowledge of astronomy. Anywho, I know that this is a kind of ridiculous topic, but ridiculous things can be very entertaining. My first question about this is why might this idea not work at all? I like to find out when my random ideas are completely infeasible for one reason or another. Secondly, what interesting thoughts can you add to this random thought? Thanks!
