late night worldbuilding idea
what if I made the point of origin for one of the civilizations in my setting a former ice giant whose atmosphere has been blown off by the expansion of its parent star into a low mass red giant
apparently a 0.5 mSol star can keep a planet orbiting at Jupiter's distance in its habitable zone for nearly 6 billion years which is literally a better prospect for life than most F-type stars, let alone anything more massive

*nearly 6 billion years after leaving the main sequence for that first toot, rather
late night worldbuilding idea, a continuation
just realized that red giants from stars with such low masses won't exist for another forty billion-odd years from now, so I'd have to justify that with a star lifting project or somesuch in setting
still though, the entire idea of a star possibly giving birth to new life even on the verge of death, in a universe that's starting to show the first signs of aging is some philosophical-ass shit

@Thaminga that'd be cool! but also wouldnt the planet have really weird geology?

@Thaminga like the core is molten metals, and hydrogen and ice

@daylight oh, absolutely
I'm here for it

@Thaminga rad, i mean easy source of water :D

@Thaminga carbon life chemistry?
late night worldbuilding idea
@daylight should work, yeah! -plenty- of water to go around in all likelihood, after all

@Thaminga oooooo

@Thaminga I initially parsed this as referring to the ice giants of Norse mythology and that would be a very interesting (and strange) world

losing the deep atmosphere and no longer viable volatiles would be a fairly quick process if the solar system's history is any indication, and you'd likely be left with something that'd ostensibly resemble early Earth, if with less geological activity
hmmmm...
