If we had a planet midway between an oxygen planet and a carbon planet where the proto planetary cloud was made of Carbon Monoxide primarily we might have interesting phenomena. Probably alcohol based...

Would methanol pool at the bottoms of the oceans like brine pools in our oceans, and stay there due to its high cohesion? I imagine life might evolve around using Methanol as a solvent because I'm uns...

Normally we only talk about Carbon worlds as a single category, a world with carbonate rocks, diamond mantle, a carbon monoxide atmosphere, and oceans of hydrocarbons. But what would an extremely vola...

I like the renames, but do you think there's important information potentially being lost that way?

Is there a clear dividing line in terms of chemistry between neptunian ydratians and thalassic super earths? They seem very similar to me and it seems to be a spectrum, but I may be misunderstanding i...

Post: RE: Fluorogaian worlds

Why is Fluorine less abundant than Chlorine? That seems to break the standard logic of elemental abundance.

Post: Fluorogaian worlds

If a Chlorogaian world is possible does that mean Fluorine could fulfill a similar role in such an ecosystem? Fluorine is more abundant than Chlorine (although less present in Terragen life) so why ar...

I think a lot of super earths fall into this category. Technically super Earth is a mass category but they will tend towards liquid domination even in Gaian ones due to maintaining thicker atmospheres...

Would it be possible for a very large planet to form similar to a gas giant, but without a supercritical mantle? This would make it have a clearly defined liquid surface below a gas atmosphere. I imag...
