i guess but it is denser. alternatively you could have a gas giant exactly like earth’s atmosphere in composition with salt in the water in the middle to stop it from freezing by slipping between the molcules in any ice
How would a gas giant form that isn’t mostly hydrogen and helium? Everything else is so rare.
artificial construction most likely
And here we go into a while separate discussion. Many species and kind of life forms could potentially be made to work - underwater civilizations, space whales, robotic life forms (though the last one differs greatly from the others) - but the question here isn’t could it be made, is it possible; it’s is it naturally possible, could it realistically evolve through natural selection?
Imo evolving on an artificial planet, even if the organism developed naturally, is not natural evolution, as the environment has been custom tailored so that it is able to work for such organisms.
Anyway what I’m trying to say is that the argument isn’t only whether or not it could feasibly exist, but whether or not it could logically and naturally evolve. This takes bioengineering/custom creating planets and the like off of the table, and means it would have to make sense step by step.
Short text wall about this kind of discussion
Tbh while this, space whales, and other arguments are good conversation startersand activity for the forum, I think the best thing to do for all of them is do what Hhyyrylainen has done with underwater civilizations - challenge someone to make a realistic, scientifically plausible argument with math for your ideas(preferably general but specific examples are probably best for this kind of arguement), so that the same ideas aren’t recycled with minimal evidence over and over. Such a thing could be advertised through a pinned thread in the future game topic that lists what subjects require this kind of explanation.
While it is a lot of work to write something like that, it also discourages less informed answers and hopefully allows for a less back and forth going nowhere, and more working out what is wrong with ideas as a whole.

We have the math for plant civs, its just unlikely to happen, one of my posts specifically showed a way it could happen.
i meant for an atmosphere exactly like earth’s it would likely have to be artificial construction but given an infinite universe and infinite time a gas giant with the exact same atmospheric composition as earth could form but assuming it has even slight percentage deviations that vastly increases the chance it will form naturally and assuming differences of even 1 percent that makes it likely enough for it to happen in almost every galaxy and
could easily evolve given an infinite universe with at least 1 gas giant with an earthlike atmosphere per galaxy
I’ll close this thread in favour of funnelling all talk about this to this earlier thread:
