I've been looking a lot at hydrothermal vents recently, because I was making a moon with a subsurface ocean that has life in it, and I found out that Sulfur can be used as an oxidant. My question is: could a biosphere exist with Sulfur in place of Oxygen? I was thinking of disulfur, but that isn't very stable according to the research I've done. I was wondering if there is a sulfur compound that could be used in place of O2, because I think a biosphere based on sulfur instead of oxygen would be really cool. Plus, who doesn't love oddly colored skies?

  • $\begingroup$ Can Sulphur be used as an oxidizing agent? Yes. But developing the chemistry to prove that an entire biome could exist based on sulphur as the primary oxidizing agent might violate the help center book rule. Do you have a specific question? (See help center). $\endgroup$

  • $\begingroup$ @JBH Oh shoot, whoops! I should probably go to some other SE for that. Would the chemistry SE do me any good for this question, or would some other one be better for that? $\endgroup$

  • $\begingroup$ Most of the help center rules are common to all Stacks. Unfortunately, the other Stacks focus on Real World applications. The odds are pretty good you'll get shuttled back here. You just need to ask a series of focused questions rather than one big global question. After all, one of the most important reasons for this Stack is to educate users in worldbuilding processes, not just shovel data (or provide free research...). $\endgroup$

  • $\begingroup$ @JBH Oh... alright, I'll delete this question, and make a new one that is more specialized, I thought I remembered a rule somewhere that said you couldn't have more than one question, but it's the exact opposite apparently. $\endgroup$
